Background

Sewage treatment generally refers to a process of purifying sewage to meet the discharge requirements or reuse requirements. The sewage treatment can be divided into a physical method, a biological method and a chemical method according to the functions of the sewage treatment. The physical method mainly separates the non-soluble substances in the sewage by physical action, and does not change the chemical properties in the treatment process. Gravity separation, centrifugal separation, reverse osmosis, air flotation, etc. are commonly used. The physical method is simple and economical in treating the structure, and is used for the conditions of large water volume of villages and towns, strong self-purification capacity and low requirement on sewage treatment degree. The biological method utilizes the metabolism function of microorganisms to decompose and oxidize organic matters in a dissolved or colloidal state in the sewage into stable inorganic substances, so that the sewage is purified. Commonly used are an activated sludge process and a biofilm process. The biological method has higher treatment degree than the physical method. The chemical method is a method for treating or recovering dissolved substances or colloidal substances of sewage by using a chemical reaction, and is often used for industrial wastewater. As the method, coagulation, neutralization, redox, ion exchange, etc. are generally used. The chemical treatment method has good treatment effect and high cost, is mainly used for effluent after biochemical treatment and further treatment, and improves the effluent quality.

In the sewage treatment process, precipitation and aeration are two common treatment means, the former is used for removing suspended particles, and the latter is used for obtaining enough dissolved oxygen in water body to degrade organic pollutants.
