The responsible departments vary from place to place. Take Fuhai Town as an example: Notice on Printing and Distributing the Management Measures for the Operation and Maintenance of Rural Domestic Sewage Treatment Facilities in Fuhai Town.
Rule number three? The town government is the main body responsible for the operation and management of rural domestic sewage treatment facilities, and is responsible for supervising the operation units to perform the operation and maintenance management responsibilities of domestic sewage treatment facilities.
Article 4? The specific management and supervision institution of rural sewage in our town is the town drainage management station, which shall do the corresponding work according to the requirements of the higher authorities and bear the corresponding supervision and management responsibilities, specifically:
1, organize to review the annual operation and maintenance management plan of domestic sewage treatment facilities.
2. Organize the supervision and inspection on the implementation of management personnel and management system of operating units.
3. Organize the supervision and inspection on the operation, maintenance and management of domestic sewage treatment facilities, and the inspection shall not be less than 1 time every ten days, and timely urge the operating units to rectify the problems existing in the operation, maintenance and management (including safety issues).
4. Organize the assessment on the operation, maintenance and management of domestic sewage treatment facilities.
5. Organize the collection and collation of inspection records, assessment and other related materials.

How to treat sewage from bean products workshop;
Flocculants are used in sewage treatment. Because the water quality produced by sewage treatment in different industries is different, the purpose of adding polyacrylamide is also different, so the temperature of sewage quality has a certain influence on flocculants. Here, we will introduce the influence of the temperature of wastewater quality on flocculants.
Too high or too low temperature of sewage quality is unfavorable to flocculation, because when the water temperature is too high, the chemical reaction speed is too fast, which makes the floc formed fine and increases the hydration of the floc, and finally makes the sludge produced high in water content, large in volume and difficult to treat.
When the water temperature is too low, the hydrolysis speed of some coagulants slows down and the hydrolysis time increases, which affects the external water treatment. In addition, when the water temperature is low, the viscosity of water increases, which increases the tearing effect of water on the driver and makes the floc fine.
Anaerobic-aerobic treatment process can give full play to the advantages of anaerobic microorganisms bearing high concentration, high load and recovering effective energy, and at the same time, it can take advantage of the characteristics of aerobic microorganisms' fast production speed and good water quality.
