Description

Baffling pond biomembrane composite sewage treatment device Technical Field The utility model belongs to the technical field of sewage treatment, and particularly relates to a baffling tank biological membrane composite sewage treatment device. Background The high-speed service areas in China synchronously construct and operate along with the rapid development of highways, but the sewage discharge of the high-speed service areas cannot be incorporated into municipal pipe networks for unified collection treatment, so the sewage treatment problem of the service areas is increasingly prominent and needs to be solved. The sewage in the high-speed service area mainly comes from restaurant wastewater, toilet wastewater, road watering water, car washing water, hotel room water, greening water, unforeseen water (pipe network drainage water) and the like. Wherein the restaurant wastewater and the toilet wastewater are the main sewage to be treated. The high-speed service area is far away from the living area and the industrial area, the sewage discharge characteristics and the pollutant composition concentration of the high-speed service area are different from those of domestic sewage and industrial sewage, and the pollutant discharge concentration of the sewage in the high-speed service area is higher than that of typical domestic sewage. The sewage discharge in the high-speed service area has larger fluctuation and larger non-uniformity coefficient under the influence of weather, seasons, time periods and the like. The emission peak is mainly concentrated on weekends and legal holidays, the daily emission is higher than at night, and the sewage emission in rainy and snowy days is less. Meanwhile, the sewage in the service area contains characteristic pollution factors, the sewage in the toilet is mainly a substance with strong biodegradability, and the kitchen waste contains a large amount of animal and vegetable grease and other refractory substances, so that the sewage in the service area needs a targeted sewage treatment process link or technology to improve the sewage treatment efficiency.
