Experiments were conducted to study the role of enhanced micro-electrolysis techniques (METs) in treatment of s-atrazine wastewater, regarding atrazine production wastewater as the object of this research. The intensified METs methods included O3and ultrasound (US). With O3METs technology, a better result could be achieved under weak acidity condition. The highest removal rate of TOC reached 18.7%. US before METs could gain higher removal rate of 38.7% compared to the rate of 27.8% by US in METs.

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.

Given the shift in perception of wastewater treatment plants as water resource recovery facilities, conventional mathematical models need to be updated. The resource recovery perspective should be applied to new processes, technologies and plant layouts. The number and level of models proposed to date give an overview of the complexity of the new plant configurations and provides a wide range of possibilities and process combinations in order to construct plant layouts. This diversity makes the development of standard, modular and flexible tools and model libraries that allow the incorporation of new processes and components in a straightforward way a necessity. In this regard, the plant-wide modelling (PWM) library is a complete model library that includes conventional and advanced technologies and that allows economic and energetic analyses to be carried out in a holistic way. This paper shows the fundamentals of this PWM library that is built upon the above-mentioned premises and the application of the PWM library in three different full-scale case studies.
