Activated Carbon For Municipal Wastewater Heycarbons Manufacturer From China

Urban sewage treatment is the basic guarantee for the operation and sustainable development of modern cities. Nowadays, municipal sewage treatment is carried out in a separate system.

Urban domestic sewage mainly comes from residents’ daily life activities and is mainly divided into two types: black water and gray water. What we call municipal sewage refers to gray water.

Black water refers to toilet drainage containing feces and urine. It is highly polluted and contains a large amount of organic matter, ammonia nitrogen, and pathogenic microorganisms.

Gray water refers to other domestic sewage except toilets, such as drainage from bathing, laundry, and kitchen. The pollution level is relatively low, but it still contains grease, surfactants, organic matter, etc.

Untreated sewage contains a large number of pathogenic microorganisms, which may lead to outbreaks of infectious diseases. Once the tap water sources of downstream cities (such as rivers, lakes, and groundwater) are polluted by domestic sewage discharged from upstream cities, it will directly affect the drinking water safety of residents.

Domestic sewage contains a large amount of organic matter, nitrogen, phosphorus and other nutrients, which will lead to eutrophication of water bodies and cause ecological disasters such as blue algae, algal blooms, and fish deaths. Sewage also contains detergents, grease, and drug residues, which have long-term effects on aquatic populations and food chains.

The available water resources in cities are limited, and water pollution will further aggravate the shortage of water resources. Treated domestic sewage can be reused for greening, flushing toilets, cleaning, cooling, etc., to relieve water pressure.
