Catering sewage treatment equipment discharges mud once per shift. Mud is too long. Mud will undergo anaerobic fermentation.

After investigating various sewage treatment examples of the biological turntable of the catering sewage treatment equipment , the treatment effect is good or bad, and the hotel sewage treatment is also good or bad. We believe that the biological turntable avoids oil pollution in sewage, so in the design and operation of the purification station, the degreasing measures of the kitchen sewage are taken seriously. The working environment of the turntable must be well ventilated. Through the operation management and monitoring of the turntable, the above two points are correct.
The two caissons of the catering sewage treatment equipment shall be drained once every 4 hours and the sludge shall be drained once per shift. Otherwise, the mud time is too long, the mud will undergo anaerobic fermentation, and it will rise in the mass, which will affect the quality of the effluent. Problems in the work of the filter tank: 1 After the filter is operated, the surface of the sand layer is knotted, and the backwash intensity and backwash time are slightly larger than the design parameters. The water level of the filter tank should be relatively stable to ensure that the filter head is higher than 2.0m. Maintenance management must be strengthened and standardized operations must be performed. Currently, fiber bundle filtration technology is developing rapidly. It has pressure and gravity, fast filtration speed, good effluent quality, and turbidity of about 1 degree. We believe that in the process of catering wastewater treatment equipment, fiber bundle pressure tanks can be used for filtration, with a small footprint, which is superior to sand filter tanks in terms of technical performance and maintenance management.
At present, many catering sewage treatment equipment, including some sewage treatment plants, have not been digested by sludge due to various factors. Only concentrated mechanical dehydration, pollutants in the sewage, parasite eggs, and pathogenic bacteria can be enriched. In sludge, not only is it difficult to dehydrate, but the sludge is not stable enough, and it still causes pollution. Therefore, we recommend that the sludge treatment structure in the catering sewage treatment equipment is a biogas digester.
The biogas digester is generally built underground, with a simple structure, low construction cost, simple maintenance and management, and does not require a built-in concentrated water tank. Digestive sludge has high dehydration and hygienic conditions, high fat content, and further degradation of organic matter. Since the operation of the purification station, the operation of the biogas digester has been relatively stable. After the sludge is digested, it can be pumped out through the discharge port at any time. It can be used directly as a fertilizer or dehydrated as an agricultural fertilizer.
