People’s daily domestic sewage mainly uses integrated sewage equipment. What is the working principle of the equipment? What method is used to treat sewage into purified water?

       The so-called sewage treatment is simply understood to be a process of making sewage reach a certain indicator for discharge or purifying its water quality so that it can be used again. Integrated sewage equipment is mainly divided into three stages:

  

       Second stage: It belongs to the microbial treatment method. The principle is to use the physiological effects of the microorganisms themselves and the decomposition and synthesis of the microorganisms put into the water to cause physiological reactions between toxic and harmful substances in the sewage and the microorganisms, which can decompose the organic matter in the sewage.

       Three stages: This is what we call the chemical treatment method. It involves denitrification, dephosphorization, ozone addition, etc. to the water that has been treated by microorganisms. The sewage treated in this step can be directly used to irrigate fields and be used as daily cleaning water.

       Basically, the sewage treated through these three steps of integrated sewage equipment can realize the reuse of water resources.
