According to the different processing methods, it can be divided into distributed processing and two different modes.

The decentralized sewage treatment mode is a brand-new attempt in the field of sewage treatment. It refers to dividing a large area into several small units, and independently laying out the pipe network and establishing sewage treatment facilities in each small unit. Do not cross each other without affecting each other. This sewage treatment mode has changed the status quo that traditional sewage treatment must be centralized, so that sewage treatment can be completed in a small area, which is more in line with the sewage treatment requirements of the actual situation of scattered living in most rural areas in my country.
