wastewater treatment machine is an industrial device that can effectively treat domestic sewage, industrial wastewater, etc. in urban areas, avoiding direct flow of sewage and pollutants into water bodies. It is of great significance for improving the ecological environment, enhancing urban quality, and promoting economic development.

The so-called primary sewage refers to untreated domestic or industrial wastewater directly discharged from cities. The current utilization method is to directly enter the sewage source heat pump system for heat exchange, and provide indoor cooling and heating for urban buildings while consuming a small amount of electricity. There are several technical difficulties that need to be overcome in the reuse of sewage: blockage, corrosion, and heat transfer efficiency.

Urban raw sewage directly enters the sewage heat exchanger for heat exchange, and the heat exchanged is transferred indoors by the heat pump inside the sewage source heat pump.

The advantages of reusing urban primary sewage are energy conservation, environmental protection, and pollution-free.

The four main methods of ink wastewater treatment clear equipment include biological treatment, physical treatment, chemical treatment, and membrane separation. Among them, biological treatment is the most widely used, which degrades organic matter through microorganisms; The physical processing method mainly involves precipitation and filtration; Chemical treatment utilizes reactions to remove pollutants; The membrane separation method achieves efficient separation through permeable membranes. ‌‌

Biological treatment method

The use of microbial metabolism to decompose organic matter is divided into aerobic (such as activated sludge process, biofilm process) and anaerobic (such as upflow anaerobic sludge bed) types, which have the advantages of low cost and no secondary pollution. ‌‌

Physical processing method

Removing suspended solids through physical means such as precipitation, filtration, and adsorption to improve wastewater turbidity and color is an auxiliary step in pretreatment or subsequent processes. ‌‌

Chemical treatment method

By using chemical reactions (such as neutralization and oxidation) to adjust pH or convert harmful substances, such as ion exchange, heavy metals can be recovered, and catalytic combustion can degrade organic matter. ‌‌‌‌
