Pain Points and Necessity of Surface Treatment Wastewater Industry

Zero discharge solution for surface treatment wastewater of Shangchen Environment
helps achieve environmental protection and benefit guarantee

What is Surface Treatment Wastewater?

It mainly refers to the wastewater generated during the processing of a layer of material covering the surface of various metal or non-metal materials. These wastewaters may contain harmful substances such as heavy metals, organic matter, etc., which pose a threat to the environment and human health.

Limitations of
traditional treatment

Although chemical precipitation and physical filtration methods can remove some pollutants, it is difficult to achieve comprehensive purification and may cause secondary pollution.

Regulatory pressure

As environmental regulations become increasingly stringent, electroplating companies face greater compliance pressure and higher environmental costs.

Environmental and
social impacts

The discharge of wastewater that does not meet treatment standards can cause damage to water bodies, soil and ecosystems, as well as pose a potential threat to human health.

Remove harmful substances

High efficiency and energy saving

Low operating cost

Comply with environmental regulations

Surface Treatment Wastewater Zero Discharge Technology

technology of Shangchen Environment

Innovative technologies drive environmental upgrades to achieve efficient processing and maximize resource utilization

Heavy metal high-precision removal
pretreatment technology

Technical principle: Accurately remove heavy metal ions from wastewater by adopting efficient chemical precipitation and electrochemical technology, ensuring the efficiency and stability of subsequent treatment links.
Innovation highlights: By adjusting chemical agents and electrochemical parameters, it can realize optimized treatment according to different wastewater characteristics, achieving higher removal efficiency and lower treatment costs.
OSMMBR biochemical technology

Technical principle: Achieve deep degradation of organic pollutants and wastewater purification through the optimized membrane bioreactor (MBR) combined with efficient oxidation process.
Innovation highlights: Improve treatment efficiency by adopting advanced oxidation technology, reduce membrane pollution, extend membrane service life and reduce maintenance costs.
SPNR technology

Technical principle:A new type of physical-chemical combined treatment technology that removes suspended matter and dissolved organic matter in water through specially designed reactors.
Innovation highlights:Efficiently remove particulate matter and soluble pollutants in wastewater, ensure that treated wastewater can be directly reused, and reduce corporate water costs.
MVR crystallization technology

Technical principle:Concentrate and crystallize wastewater, precipitate soluble metal ions by adopting mechanical vapor recompression (MVR) technology, and achieve resource recovery.
Innovation highlights:Compared with traditional evaporation crystallization technology, MVR technology has lower energy consumption, lower operating costs, higher metal recovery rate, and reduces the generation of solid waste.
