Description

Wastewater treatment equipment

Technical Field

The utility model relates to a quality of water clarification plant technical field, concretely relates to waste water treatment equipment.

Background

At present, most of waste water treatment equipment adopts a sedimentation tank for waste water treatment, such as a common radiation type sedimentation tank and a high-density sedimentation tank. Patent with publication number CN209128112U discloses a radial sedimentation tank, the body of which is circular, when in use, wastewater enters the tank from the central inlet pipe of the tank and slowly flows to the periphery of the tank along the radius direction. The suspended matters are settled in the flow and enter a sludge hopper along the gradient of the bottom of the tank, and the clarified water overflows from the periphery of the tank and flows out of a water channel. Sludge is collected by a rotary mud scraper, and the sludge settled to the bottom of the tank is scraped to a sludge hopper at the center of the tank by a scraper plate of the mud scraper and is discharged by gravity or a sludge pump. Because the water flow velocity of the sedimentation tank is unstable, the sedimentation tank is greatly influenced by water inflow, the water outflow is unstable, the sludge sedimentation effect is poor, the wastewater treatment efficiency is low, and energy is wasted, the improvement is urgently needed.
