What are the divisions of industrial sewage treatment equipment?

This is an article about industrial sewage treatment equipment. I hope it can help you a little bit. Let's take a look at the article.

The treatment technology of industrial sewage treatment equipment can be divided into primary, secondary and tertiary treatment according to the degree of treatment.

primary treatment：

Industrial sewage treatment equipment mainly removes suspended solid pollutants in sewage, and most of the physical treatment methods can only complete the requirements of primary treatment. After primary treatment of sewage, BOD can generally be removed by about 30%, which does not meet the discharge standard. The primary treatment belongs to the preprocessing of the secondary treatment.

Secondary processing：

It mainly removes organic pollutants in colloidal and dissolved state in sewage, and the removal rate can reach more than 90%, so that organic pollutants can meet the discharge standard.

Tertiary treatment：

Further treatment of refractory organic matter, nitrogen and phosphorus and other soluble inorganic matter that can lead to eutrophication of water bodies. The main methods of industrial sewage treatment equipment include biological denitrification and phosphorus removal, coagulation and sedimentation, sand rate method, activated carbon adsorption method, ion exchange method and electroosmosis analysis method.
