Description

Technical Field

[0001] The invention belongs to the technical field of sewage, and in particular relates to an environmental protection mechanism for sewage treatment. Background Art

[0002] Sewage treatment refers to the treatment of wastewater generated in the fields of life, industry, agriculture, etc. to remove harmful substances and pollutants so that it meets the discharge standards or reusable water quality requirements. The main purpose of sewage treatment is to protect the environment and human health. Sewage treatment environmental protection institutions are equipment or systems used to treat sewage and purify the discharged water. These institutions usually include various technologies and equipment to ensure that sewage discharged from industry, cities and rural areas is properly treated to meet the requirements of environmental protection. The biological filter system is a common sewage treatment institution that uses biodegradation to remove organic matter and pollutants such as nitrogen and phosphorus from sewage.

[0003] The bioreactor rollers in existing sewage treatment and environmental protection mechanisms are unable to stir the sewage. The solid matter produced after the sewage reaction is easily deposited in the treatment system pipes and on the surface of the bioreactor membrane, which will block the pipes and affect the treatment efficiency. When there is no stirring device, it is necessary to manually clean the sediment and sludge in the sewage treatment equipment regularly, which will increase the operating cost. At the same time, the existing sewage treatment and environmental protection mechanisms have no function of cleaning and discharging the flocs produced by the reaction after filtering them, resulting in the suspended matter in the sedimentation tank gradually accumulating at the bottom of the tank to form a sludge layer. If the sludge is not cleaned regularly, the sludge layer will continue to thicken, reducing the sedimentation effect and affecting the treatment effect. Summary of the invention
