First of all, rural domestic sewage can be treated with integrated sewage treatment equipment.
Secondly, sewage treatment processes are mainly divided into activated sludge process and biofilm process; Activated sludge methods mainly include oxidation ditch method, A/B method, A2/O method and aeration method. Biofilm method includes biological turntable method and contact oxidation method.
The water treated by integrated sewage treatment equipment meets the national sewage discharge requirements, that is, it can be directly discharged. What are the characteristics of integrated sewage treatment equipment?
1, the equipment has strong impact load resistance, and the average residence time of contact oxidation method can reach more than 6 hours.
2. The sludge output of this equipment is low, and the effluent quality is stable.
3. The equipment is simple in structure and the operation can be automatically controlled.
4. At present, integrated sewage treatment equipment can be applied to urban sewage, industrial sewage and domestic sewage. The reason is that the equipment has the ability of nitrogen and phosphorus removal.
5. The equipment can be connected to a car to make a mobile integrated sewage treatment equipment.
Buried sewage treatment equipment is also a kind of comprehensive sewage treatment equipment, which is often used in hotels, restaurants, nursing homes, hospitals, residential quarters, villages and so on.
