Treatment and disposal of surface wastewater and Sludge

Abstract

The main sources of surface wastewater pollution are products of soil washout, destruction of asphalt and so on. Surface wastewater pollutes water bodies with suspended, surface-active substances, oil products, organic impurities, heavy metal ions and other pollutants. Precipitation leads to pollution and siltation of watercourse channels, disrupts the vital activity of living organisms, microorganisms, and has a negative effect on the biocenosis and self-cleaning ability of water bodies. The aim of the study was to develop a technology for treating surface wastewater from coal industry enterprises using a new water filtering facility, a clarifier reactor. The composition of the enterprise’s surface wastewater was studied. A draft of a new wastewater treatment plant and a clarifier reactor were developed. The quality of the treated water corresponded to the requirements. As a result of theoretical and experimental studies, a technology for the storm sewage treatment of industrial enterprises was developed, which allows them to be dumped into open water bodies or used for disposal in industrial water supply enterprises.
