Description
Technical Field

Background
With the continuous increase of the economic level, the total sewage amount is also continuously increased. Thus, the need for wastewater treatment is also increasing. The sedimentation tank is a structure for removing suspended matters in water by sedimentation and is a device for purifying water. The natural precipitation or coagulating sedimentation of water is used to remove suspended substances in water. The sedimentation tank is divided into a horizontal sedimentation tank and a vertical sedimentation tank according to the water flow direction. The sedimentation effect is determined by the flow rate of the water in the sedimentation basin and the residence time of the water in the basin.
Because the industrial water plant has lower requirements on water quality (except special industry), but has higher requirements on the cost of water purification treatment, the use of an efficient treatment process is necessary for treating industrial water. The high-efficiency sedimentation tank in the integrated sewage treatment equipment is used for enabling turbid liquid in sewage to achieve solid-liquid separation to a certain extent. The traditional high-efficiency sedimentation tank is divided into four parts of a coagulation area, a flocculation area, a pre-sedimentation area and an inclined plate sedimentation tank, coagulant is firstly added into raw water, and a certain speed gradient is ensured through the stirring effect of a stirrer, so that the coagulant and the raw water are quickly mixed. And (3) entering a flocculation tank, adding a flocculating agent, shearing suspended solids in the water history under the stirring of a stirrer in the tank, and fumigating to form larger floccules easy to settle. The wastewater enters a sedimentation tank which is divided into a pre-sedimentation area and an inclined tube sedimentation area; the floccules which are easy to precipitate in the pre-sedimentation area are quickly settled, the unoccupied floccules are precipitated and the micro floccules which are difficult to precipitate are captured by the inclined tube, and finally the high-quality effluent is collected and discharged through the water collecting tank at the top of the pond. However, in the normal operation period of the high-efficiency sedimentation tank, the pre-sedimentation area is easy to form accumulated mud, long-time accumulation can lead the anaerobic and anaerobic water to float up to the water surface, the sanitation of the tank body is seriously influenced, and the water quality of the water outlet is influenced, so that the floating mud and the settled mud are required to be manually salvaged for a long time, the time and the labor are wasted, and the manpower resource is occupied. In view of this, we propose an auxiliary plug flow system for a high-efficiency sedimentation tank of a sewage plant.
