Abstract
Operation of centralized wastewater disposal systems requires not only technical, but also organizational measures. The efficiency of these measures can be assessed by increasing the quality of wastewater treatment. The analysis of operation of facilities in the northern conditions and the zone of sharply continental climate demonstrates a number of issues that require urgent solution. According to the studies of biological wastewater treatment in such conditions, a comprehensive approach should be taken, considering climatic parameters and conditions of their operation, along with technological features of wastewater treatment plants. The paper considers the performance indicators of two water treatment plants located in the northern districts of Irkutsk Oblast. Insufficient wastewater treatment for some pollutants was revealed. A complex analysis was carried out, which identified a number of possible causes of exceeded concentrations of pollutants. Maximum permissible concentrations set for fishery water bodies were used as normative indicators. In order to provide a more complete and in-depth analysis, each stage of treatment should be evaluated according to the implemented scheme in accordance with the project and the developed technological regulations, and the optimal parameters and wastewater analyses should be specified step-by-step. A preliminary analysis resulted in a number of measures to improve the efficiency of wastewater treatment and to justify the introduction of a system for the quality control of wastewater discharged by consumers.
