Introduction. The authors carried out a comparative analysis of Russian and foreign approaches to regulatory and legal regulation of technologies for industrial treatment of wastewater and its sediments concerning parasitic pathogens. The scientific and applied aspects of introducing domestic lime-containing reagents into disinvasion technology, which can be an alternative to energy-intensive and expensive water treatment methods, have been updated. For consideration by the R.F. Department of water and communal services, the work presents a comparative analysis of Russian and European regulatory and legal acts on the use of reagent compositions of slaked/quicklime in industrial technologies for decontamination and disinfection of sewage and their sediments. Standardization of processes and quality of wastewater disinvasion and its sediments with justification of measures to strengthen hygienic control in the world community of water treatment is updated. Materials and methods. applied methods of overview, comparative analysis to evaluate the regulatory and legal regulation of technological techniques that ensure parasitocidal efficiency of wastewater treatment and its sediments in industrial water treatment. Results. The data of full-scale studies of the waters of the surface reservoirs of the Moscow region and the quality of wastewater treatment at discharge points indicate the low efficiency of disinvestment of urban wastewater from centralized wastewater disposal, entering the hydraulic structures of the metropolis and their contribution to the total level of high parasitic pollution of surface water sources. Conclusion. The analysis of the regulatory regulation of the wastewater treatment and sediments industry showed no development of standardization of wastewater and sediments treatment sub-processes and their complete disinvasion according to parasitic safety criteria. A comparative analysis of measures to enhance hygienic assessment of the quality of cleaning and production of secondary products from formed waste and sediments also showed that preliminary work was done with best available technologies (BAT-5) (information technology support (ITS) 10-2015) on compliance with the sanitary legislation of the Russian Federation, including in terms of legal regulation of standard procedures for the production of by-product (biogas, organic fertilizer, soil, recultivant, etc.) or practically non-hazardous or low-hazard waste intended for placement in the environment.

Рассмотрен опыт внедрения современных технологий очистки сточных вод на очистных сооружениях г. Москвы, описаны технологические схемы для сооружений разной производительности. С конца 1990-х годов Инженерно-технологическим центром АО «Мосводоканал» проводились работы по разработке и внедрению современных технологий очистки сточных вод с удалением биогенных элементов. Поскольку состав сточных вод имеет отличия на разных очистных сооружениях, не удается «перенести» зарубежные технологии без изменения и адаптации, а иногда требуется разработка технологии «с нуля». Более чем за 20-летний период осуществлено поэтапное внедрение современных технологий на московских очистных сооружениях Южного Бутова и Зеленограда, блока удаления биогенных элементов Люберецких очистных сооружений (БУБЭ ЛОС), нового блока Курьяновских очистных сооружений (НКОС). В настоящее время идет реконструкция ЛОС (старый и новый блоки), планируется реконструкция старого блока КОС, в процессе реконструкции находятся очистные сооружения Троицкого и Новомосковского административных округов (ТиНАО) г. Москвы. Опыт АО «Мосводоканал» был использован при разработке справочника наилучших доступных технологий ИТС 10-2015. Разнообразие технологических решений позволяет обеспечить нормативное качество очистки для условий разных сооружений. The experience of introducing advanced technologies for wastewater treatment at the wastewater treatment facilities in Moscow is considered; process flow schemes for the structures of different capacities are described. Since the late 1990s, the Engineering and Technology Center of Mosvodokanal JSC has been working on the development and introduction of advanced wastewater treatment technologies with the removal of nutrients. Since the composition of wastewater differs at different treatment facilities, it is not possible to "transfer" foreign technologies without correction and adaptation; moreover, sometimes the development of technology "from square one" is required. For more than 20 years, a stepwise introduction of advanced technologies has been carried out at the Moscow treatment facilities of South Butovo and Zelenograd, at the nutrients removal block at the Lyuberetskie wastewater treatment facilities, at the new block of the Kurianovskie Wastewater Treatment Facilities. At present, the reconstruction of the Lyuberetskie Wastewater Treatment Facilities (old and new blocks) is underway, the reconstruction of the old part of the Kurianovskie Wastewater Treatment Facilities is planned, the treatment facilities of the Troitsk and Novomoskovsk administrative districts in Moscow have been under upgrade. The experience of Mosvodokanal JSC was used in the development of an ITS 10-2015 reference book of the best available technologies. A variety of process solutions provides for ensuring the standard quality of effluent for the conditions of different facilities.

Developing countries' experience is a huge gap in the coverage of collection-system and domestic wastewater treatment. Wherever the wastewater treatment facilities are available, they are running below the design standards. This leads to the discharge of pollutants into the natural water bodies and creating a negative impact on the environment and human health as well. Odor nuisance has become a major environmental issue worldwide with increasing public demand for better control of odor emissions from the municipal wastewater treatment facilities. Odor get affects the population directly and there is a trend that more and more peoples are becoming less tolerable with more odor emissions. Bad smell is often an indicator of the public potential health risk. Performance assessment of Haya water treatment plant in Manuma Village has been done. The main objective of this study is to assess the performance of the treatment plant with respect to produce high quality of treated water and reduce odor complaints. Influent and effluent samples were collected at critical treatment steps of the plant and analyzed for chemical, physical and microbial parameters. The study will be used to monitor the Manuma wastewater treatment plant and compare its performance to that one that uses the Sequence Batch Reactor (SBR) process. Study shows that process with wet scrubber technology will be the suitable treatment process to create an environment without any health-related issues, and selecting these alternative treatment facilities with the latest technology will lead to creating high-quality of treated water without any odor issues.

При эксплуатации сооружений очистки природных и сточных вод могут изменяться условия относительно принятых в проектных решениях. Вследствие этого очистные сооружения прекращают выполнять возложенные на них функции. До реконструкции таких сооружений водоподготовки и очистки сточных вод инженерно-техническое обследование является основой принятия верных технико-технологических решений. При обследовании используется алгоритм принятия решений, направленный на достижение поставленных целей при проектировании мероприятий по реконструкции и их внедрении. На примере одного из предприятий пищевой промышленности рассмотрено положительное влияние проведения расширенного инженерного обследования на принятие верных точечных технико-технологических решений, позволивших обеспечить надлежащее качество очистки сточных вод при оптимальных капитальных вложениях. During the operation of natural and waste water treatment facilities, conditions may change in relation to those accepted in design decisions. As a result, the treatment facilities cease to perform the functions assigned to them. Before the reconstruction of such water treatment and wastewater treatment facilities, engineering and technical examination is the basis for making the right technical and technological decisions. The examination involves a decision-making algorithm aimed at achieving the goals set while designing. Through the example of one of the food industry enterprises, the authors considered the positive impact of an extended engineering examination for the acception of correct technical and technological solutions that provide the proper quality of wastewater treatment with optimal capital investments.

Introduction. A review of the judicial practice of securing land use rights on the territory of sanitary protection zones (SPZ) of sources of centralized household drinking water supply of the population, a comparative analysis of Russian and foreign approaches to the legal regulation of sanitary protection of sources of centralized household drinking water supply (starting now - SPZ). The computational methods for assessing the spread of pollutants and determining the size of the boundaries of the 2 nd zone of the WSS for water sources, analysis of the degree of protection of aquifers of drinking water supply sources, which can become an alternative to expensive measures to prohibit economic activities in the territory of the SPZ, have been updated. The data on the water pollution of the sources of the centralized drinking water supply of the population of the Russian Federation, the Moscow River, on the effect of surface runoff polluted with persistent organic substances on the sanitary state of surface waters are presented. Material and methods. Methods of the survey, comparative analysis were applied to assess the legal regulation of sanitary protection of sources of centralized drinking water supply to the population in urbanized areas, hygienic assessment of water pollution, correlation and regression analysis. Results. The data of field studies of surface water bodies and groundwater in the Russian Federation indicate the low efficiency of wastewater treatment to ensure water quality safety in the sources of centralized drinking water supply to the population. On the one hand, the low efficiency of groundwater protection and the ability to protect groundwater due to natural conditions are shown. Judicial practice confirms the need to establish the security of a water supply source from wastewater when justifying health hazards and violations of current regulations. Conclusion. The analysis of the legal regulation of the protection of sources of centralized economic water supply to the population and treatment, wastewater disposal showed that the issues of the legal status of the territory of the SPZ of water sources are not developed. The need to standardize approaches to the organization of SPZ and the methods used to ensure the protection of sources of centralized drinking water supply to the population was not evaluated.

Recently, process control in wastewater treatment plants (WWTPs) is, mostly accomplished through examining the quality of the water effluent and adjusting the processes through the operator’s experience. This practice is inefficient, costly and slow in control response. A better control of WTPs can be achieved by developing a robust mathematical tool for performance prediction. Due to their high accuracy and quite promising application in the field of engineering, Artificial Neural Networks (ANNs) are attracting attention in the domain of WWTP predictive performance modeling. This work focuses on applying ANN with a feed-forward, back propagation learning paradigm to predict the effluent water quality of the Habesha brewery WTP. Data of influent and effluent water quality covering approximately an 11-month period (May 2016 to March 2017) were used to develop, calibrate and validate the models. The study proves that ANN can predict the effluent water quality parameters with a correlation coefficient (R) between the observed and predicted output values reaching up to 0.969. Model architecture of 3-21-3 for pH and TN, and 1-76-1 for COD were selected as optimum topologies for predicting the Habesha Brewery WTP performance. The linear correlation between predicted and target outputs for the optimal model architectures described above were 0.9201 and 0.9692, respectively.
