Description

water disposal system The present disclosure relates to a water treatment system. Various pollutants generated in our surroundings can be classified into point source pollutants and non-point source pollutants. Point source pollutants are those discharged from so-called point sources, which have distinct and limited origins, such as domestic sewage or industrial wastewater from households or factories. In contrast, non-point source pollutants are those originating from extensive areas without defined pollution zones, such as farmlands, pastures, forests, or roads. Non-point source pollutants include, for example, fertilizers and pesticides sprayed on farmland, livestock effluent, dust and heavy metals, pathogenic microorganisms, organic compounds, radioactive materials, and untreated sewage overflow. These pollutants remain stagnant as dust and debris or accumulate within sewer pipes, and when it rains, they are washed away by the initial rainwater and flow into nearby sewage treatment plants, groundwater, lakes, reservoirs, or the ocean. Therefore, it is crucial to prevent the initial rainwater from flowing directly into sewage treatment plants, groundwater, lakes, reservoirs, or the ocean. Accordingly, various types of non-point source pollution reduction facilities are being applied in recently developed new towns, residential districts, or heavily polluted areas to prevent environmental pollution caused by non-point source pollutants. As a type of water treatment facility, these reduction facilities pass water containing non-point source pollutants—such as initial rainwater, untreated sewage overflows (CSOs, SSOs) during rainfall, and water from contaminated lakes and reservoirs—through their interiors to filter out pollutants and discharge the water in a partially purified state. Meanwhile, although the treated water, which has been purified to some extent by filtering out these pollutants, has a large proportion of non-point source pollutants compared to the initial rainwater, organic pollutants including phosphorus remaining in the treated water can flow back into sewage treatment plants or groundwater without being filtered and can also cause odors. Therefore, it is necessary to improve the filtration performance of water treatment facilities to additionally filter out harmful substances remaining in this treated water.
