Residential sewage treatment project
Release time:
2024-06-25
The domestic sewage of this project is mainly the sewage used in daily life in the community and various detergents, garbage, feces, etc. The domestic sewage of this community contains mostly nitrogen, phosphorus, and sulfur, and there are more carcinogenic bacteria. The domestic sewage treatment process generally determines the degree of sewage treatment and the corresponding treatment process according to the use or discharge of sewage and the natural purification capacity of the water body. The treated sewage is partly used for greening and irrigation. Sludge is treated with agricultural fertilizer operated outside the manure truck.

Solutions and technical features
SOLUTIONS AND TECHNICAL FEATURES
According to the actual investigation of the district, our company's technical group has formulated the corresponding process flow for the district, which effectively solves the problem of daily domestic sewage treatment in the district.
1. The combination of hydrolysis acidification and biological contact oxidation can effectively improve the treatment effect, and the treated water can meet the national emission standards.
2. Less sludge is produced, the sludge produced at each stage can be returned and digested, and the final sludge is extracted regularly.
3, the process can be organically combined together, can be located under the surface of the underground, the surface can be built as a parking lot or green lawn, embellishing the surrounding environment.
4. The complete set of equipment has high automation. The automatic control operation of fans, water pumps and other equipment in the system reduces the operating workload. The equipment adopts effective measures to reduce noise and odor, and has no impact on the surrounding environment.
5. The effluent can be used again after advanced treatment.
Effect after treatment
THE EFFECT AFTER TREATMENT
The effluent quality of the sewage treatment system designed for the district is good, the main water quality indicators can meet the discharge standard, which can well adapt to the unstable water quality of the influent, and the effluent of the system can reach the first-class standard of comprehensive sewage discharge, which effectively solves the reality that the effluent color can not meet the standard. According to the actual requirements and design process, the combination of hydrolysis acidification and biological contact oxidation is used to improve water quality, meet the requirements of effluent standards and ensure the long-term stable operation of the sewage treatment system.
