Background

The information disclosed in the background of the utility model is only for enhancement of understanding of the general background of the utility model and is not necessarily to be taken as an admission or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

Sewage treatment refers to the process of purifying sewage to meet the water quality requirement of being discharged into a certain water body or reused. The sewage treatment is widely applied to various fields of buildings, agriculture, traffic, energy sources, petrifaction, environmental protection, urban landscapes, medical treatment, catering and the like, and the sewage treatment is increasingly carried into the daily life of common people.

Sewage treatment can be classified into three kinds of physical methods, biological methods and chemical methods according to their functions.

The physical method mainly utilizes physical action to separate insoluble substances in sewage, and does not change chemical properties in the treatment process. Commonly used are gravity separation, centrifugal separation, reverse osmosis, air flotation, etc. The physical method has simple and economical treatment structure and is used for the conditions of large water volume, strong self-cleaning capability and low sewage treatment degree requirement in villages and towns.

Biological method, which utilizes the metabolism function of microorganism to decompose and oxidize organic matters in dissolved or colloid state into stable inorganic matters, so as to purify the sewage. Commonly used are activated sludge process and biofilm process. Biological processes are more highly processed than physical processes.

Chemical methods, which are methods for treating or recovering dissolved or colloidal substances of sewage by chemical reaction, are widely used for industrial wastewater. Examples of the conventional methods include coagulation, neutralization, redox, and ion exchange. The chemical treatment method has good treatment effect and high cost, and is mostly used as effluent after biochemical treatment for further treatment, thereby improving the quality of the effluent.
