At present, all dewatered sewage sludge generated by sewage treatment works (STW) is disposed of at landfills. This current practice of sludge disposal at landfill is not sustainable from both environmental and technical perspectives. The Hong Kong sludge contains high content of chloride due to use of seawater flushing in most of the Hong Kong areas and Hong Kong is a densely populated city. This unique condition has limited its selection of the alternative sludge treatment technology. The Sludge Treatment Facilities (STF) adopting fluidized bed incineration technology is a sustainable alternative for sludge disposal in Hong Kong. The design capacity of the STF is 2000 wet tonnes per day. The STF will be implemented under a Design-Build-and-Operate contract arrangement with a contractual operation period of 15 years and is scheduled to be commissioned by 2012.

Abstract This research paper tries to identify and address issues related to efficiency of Sewage Treatment Plants (STPs) and their implications on the Dal Lake ecosystem in Srinagar city, Kashmir, India. Fluidized Aerobic Bioreactor (FAB) and Sequential Batch Reactor (SBR) technologies having been recently installed along the periphery of Dal Lake were evaluated for efficiency for a continuous period of 24 months from December 2016 to November 2018. Apart from chemical quality, total coliform (TC), fecal coliform (FC), and fecal streptococci (FS) analyses were also carried out. Major highlights of our work using one-way ANOVA (Analysis of Variance) revealed significant variations (p < 0.05) in Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), ammonia (NH3-N), total phosphorus (TP), TC, FC, and FS. Our findings indicate that both technologies are struggling for removal efficiency, which is very low, especially in FAB during three to four months of winter season where a very high drop in the working efficiency of the STP was observed. The treatment facilities did not meet the prescribed standards in respect of TSS, BOD, NH3-N, TP, TC, FC, and FS thereby having the potential to compromise public health and trophic status of Dal Lake.

Small wastewater treatment plants suffer from higher specific peak loads and less qualified operational services. Therefore, small plants need special rules for design, construction and operation on the basis: the smaller, the less sophisticated - the less sophisticated, the better! Advantages and disadvantages as well as process stabilities of activated sludge plants with long time aeration, trickling filters, rotating bio-contactors and different pond systems are described and compared to each other. Technical plants should be preferred for serving housing estates when separate sewerages exist. Ponds are a favourable solution for villages with combined sewerages, especially such in rural areas. Emergent hydrophyte treatment systems (reed beds) are considered as still being under development. Practice proves that newly developed, highly sophisticated technical systems tend toward simplification, and small reaction volumes or areas are increasing when applied under practical conditions.

Large-scale livestock pollution has become the third largest source of pollution following industrial pollution and domestic pollution. The possible dangers of livestock sewage pollution on rivers, lakes, underground water, soil, human health are pointed out. Pretreatment is necessary for processing of livestock sewage treatment. The principle, advantages and disadvantages, applicability of three modes of livestock sewage treatment including land spreading, natural treatment and industrialized treatment are summarized. It is very necessary to study and develop efficient, low-cost, resource utilization of livestock sewage treatment technology according to local conditions.

Rural domestic refuse treatment technology is a complex uncertainty problem, which should consider not only the technical performance of rural domestic refuse treatment technology, but also its suitability for the social, economic and environmental situation of particular rural region. In this paper, Set pair analysis theory and information entropy method is used to evaluate rural domestic refuse treatment technology option.A case study was conducted in Wanxing Village in Chengdu City, and the evaluation results matched the local conditions. The method can serve as the decision analysis tool for sewage treatment technology demonstration and promotion in rural areas.

The development of heavy pollution industry has a certain impact on the ecological environment. This paper combs and summarizes the environmental treatment technology of heavy pollution industry from the aspects of air pollution and water pollution. During studing the advantages and disadvantages of various environmental treatment technologies, the authors finds that there are the following problems in the development of environmental treatment technology of heavy pollution industry in China: there is a lack of long-term planning for air pollution environmental treatment; The cost of water pollution control is high and the energy consumption is large. Therefore, relevant environmental governance departments should promote the concept of sustainable development and strengthen the constraints of waste gas and sewage treatment process; Enterprises in heavy pollution industries need to learn and learn from the cutting-edge technologies of environmental governance; Social media positively guide enterprises in heavily polluting industries to protect the ecological environment through public supervision.

The Village

The article analyses the accessibility of medical facilities in rural areas of modern Russia and the specifics of their organization and development. The authors reveal causes why rural residents have much less opportunities to seek quality medical care than urban ones, what leads to a disparity between the inhabitants of the city and the village. The thesis is substantiated that state programmes that should make health services accessible to the rural population to a greater extent do not cope with the task at hand. An attempt is made to highlight the public’s response to the existing disparity in the health services of the villagers compared to urban dwellers. Such a reaction can be considered an outflow of people from rural areas, and an increase in self-medication among rural people as a result of the difficulty in obtaining health services. The decrease in the number of treatment facilities in rural areas leads to a deterioration in the medicine situation in rural areas. That, according to the authors of the article, justifies the need to study the issues associated with the provision of medical care to the rural population.

Pyridine Degradation

Bacterial strains capable of degradation of 0.8-15.8 g/1 pyridine hydrochloride have been isolated from activated sludge of municipal biological treatment plants in Perm (BOS) and local treatment facilities of the LUKOIL-Permnefteorgsintez enterprise (PNOS). The strains were identified as Achromobacter pulmonis and Burkholderia dolosa. The optimal pyridine concentration for the growth of the isolated strains was 4.0 g/1. The pyridine degradation during the A. pulmonis PNOS and B. dolosa BOS cultivation on a medium with ammonium chloride and glucose and without additional nitrogen or carbon sources was studied. It was shown that the strains are able to accumulate biomass in a medium with pyridine as the sole carbon and nitrogen source; the addition of glucose to the medium (1 g/L) accelerated the pyridine degradation by A. pulmonis PNOS, but inhibited the process carried out by B. dolosa BOS. B. dolosa BOS and A. pulmonis PNOS biofilms efficiently utilized pyridine during growth on basalt and carbon fibers; the highest rate of pyridine utilization (1.8 g /(L day)) was observed in A. pulmonis PNOS biofilms on basalt fibers. pyridine, biodegradation, activated sludge, biofilms, Achromobacter pulmonis, Burkholderia dolosa The authors grateful to Dr. I.I. Tchaikovsky, Head of the Laboratory of Geology of Mineral Deposits of the Mining Institute, a branch of the Perm Federal Research Center, for help with electron microscopy of the samples. This work was carried out as part of a state assignment on the topic « Study of the Functional and Species Diversity of Microorganisms Useful for Ecocenoses and Human Practical Activity», registration number R&D AAAA-A19-119112290008-4.
