Small rural sewage treatment works
Release time:
2024-06-25
The effluent quality of the sewage treatment system designed for the countryside is good, the main water quality indicators can meet the discharge standards, which can well adapt to the unstable water quality of the influent, and the effluent of the system can reach the first level of comprehensive sewage discharge standards, which effectively solves the reality that the effluent color cannot meet the standards. 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.
Case analysis
CASE ANALYSIS
Product classification: Domestic sewage treatment engineering
Project name: Henan rural sewage treatment
Pollution control type: daily life sewage treatment
Processing scale: daily processing capacity of 300 tons
Implementation of standards: integrated emission standards
Treatment process: combined hydrolysis acidification and biological contact oxidation
Project introduction: small-scale rural domestic sewage treatment project, the treatment water volume of the project is 300m/d, and the treatment effect reaches the national first-class discharge standard.
Characteristics and difficulties of domestic sewage treatment
CHARACTERISTICS AND DIFFICULTIES OF SEWAGE TREATMENT
The domestic sewage of this project is mainly the sewage used in daily life in rural areas and various detergents, garbage, feces, etc. The domestic sewage in this rural area 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.
Solutions and technical features
SOLUTIONS AND TECHNICAL FEATURES
According to the actual investigation of the countryside, our company's technical team has formulated the corresponding technological process for the countryside, which effectively solves the problem of daily domestic sewage treatment in the countryside.
1, the use of hydrolysis acidification and biological contact oxidation combination method, effectively improve the treatment effect, treated water.
It can meet 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 fan, water pump and other equipment in the system operate automatically, reducing 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 countryside is good, the main water quality indicators can meet the discharge standards, which can well adapt to the unstable water quality of the influent, and the effluent of the system can reach the first level of comprehensive sewage discharge standards, which effectively solves the reality that the effluent color cannot meet the standards. 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.
