In order to protect the environment and prevent industrial wastewater from polluting water resources, we need to treat industrial wastewater. The treatment of industrial wastewater must be targeted, and different wastewater treatment schemes should be used. So, what are the treatment methods of industrial wastewater? The editor summarized four points and discussed with you.
1. Biological treatment method
The main method is to use the metabolism of microorganisms to remove organic pollutants in wastewater. Commonly used methods include activated sludge method, biofilm method, oxidation pond method, sludge digestion method, etc., which can remove colloids and soluble substances.

2. Chemical method

Mainly through the action of chemical reactions, the conversion, separation, and recovery of pollutants in wastewater. The methods include neutralization, coagulation, chemical precipitation treatment and redox treatment. The purpose is to adjust the pH value and remove suspended solids. , Colloidal and soluble substances.

3. Physical Law

It is mainly separated according to the different proportions of suspended solids contained in wastewater by physical action, which can be separated by gravity, centrifugal separation, filtration, evaporation and crystallization, etc. The purpose is to remove suspended solids and gel-packed substances.

4. Physical and chemical treatment method

It mainly includes electrolysis, adsorption, membrane separation and magnetic separation methods to remove suspended, colloidal and soluble substances.
