Environmental Pollution by Wastewater from the Urban Sector

The problem of environmental pollution by wastewater from the urban sector is considered. The composition of these waters and their impact on aquatic ecosystems depending on the content of soluble phosphates and polyphosphates are analyzed. A photometric analysis was performed to quantify the level of soluble phosphates. The results of hydrochemical analysis of wastewater for the content of soluble phosphorus compounds are presented. Increased concentration of phosphorus compounds entering the environment with wastewater and contributing to its pollution, especially in the absence of a sewerage system, was revealed. It is concluded that it is necessary to control the phosphate content in domestic wastewater.
