Primary enhanced treatment process for domestic sewage treatment station equipment:

For example, primary enhanced treatment refers to the use of physical, chemical and other enhanced treatment methods based on the planning requirements and scale of urban domestic sewage treatment facilities construction. AB method obtains front-end process and front-end technology. Hydrolysis method, aerobic method, and activated sludge method can all be used.

Secondary treatment process of domestic sewage treatment station equipment:

1. Sewage facilities with a daily processing capacity exceeding 200000 cubic meters (excluding 20 cubic meters per day) generally use conventional activated sludge method, but other mature technologies can also be used.

For sewage facilities with a daily processing capacity of 100000 to 200000 cubic meters, some mature technologies can be adopted, such as conventional activated sludge method, oxidation ditch, SBR, and AB method.

3. For sewage treatment plants with a daily processing capacity of less than 10 cubic meters, oxidation ditch, SBR, hydrolysis aerobic, AB, biofilter or conventional activated sludge method can be used for treatment.
