Fourth, it is easy to complete automatic control and simple management and operation.
In addition, the fillers in the contact oxidation tank of underground integrated domestic sewage treatment equipment are mostly combination soft fillers, which are lightweight, high-strength and have stable physical and chemical properties, large specific surface area, strong biofilm adhesion ability, and high contact efficiency between sewage and biofilm. high.
