Industrial and Domestic Wastewater

Industrial wastewater mainly comes from production wastewater, production sewage and cooling water. Industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health.

Domestic sewage refers to the waste water discharged by people in their daily life activities. Domestic sewage contains a large number of bacteria and pathogens, which can lead to the spread of infectious diseases.

Technology

Wastewater treatment is a method of separating the pollutants contained in the waste water, or converting them into harmless substances, so that the waste water can be purified.

Sludge dehydration and drying

Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complex and expensive part of the operation of the sewage treatment system.

Technology

A typical sludge dehydration and drying process generally goes through sludge concentration-sludge digestion-sludge dehydration-sludge drying-sludge disposal.
