Abstract

The invention discloses a small sewage treatment sedimentation tank. The small sewage treatment sedimentation tank comprises a hull, a water inlet, a water outlet pipe and a support. The water inlet is communicated with a rectifier tank in one side in the hull. Flow baffles are fixedly installed in the hull. A set of sedimentation sloping plates are arranged below the hull. The bottom of the hullis provided with mud vents at equal intervals. The rectifier tank reduces the power of sewage entering the hull and reduces the sewage flowing rate so that the sedimentation is convenient. The at least two flow baffles can further reduce the water flow rate in the hull and stabilize the water. The set of sedimentation sloping plates accelerate the precipitation so that sludge floating is avoided.Through use of a slag discharge pipe and a slag blocking plate, the automatic floating slag removal is realized.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment equipment, and in particular relates to a small sewage treatment sedimentation tank. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. It is an equipment for purifying water quality. It uses the natural precipitation of water or the effect of coagulation and sedimentation to remove suspended solids in water. The sedimentation tank is divided into horizontal sedimentation tank and vertical sedimentation tank according to the direction of water flow. The sedimentation effect depends on the flow rate of the water in the sedimentation tank and the residence time of the water in the tank. Sedimentation tanks are widely used in wastewater treatment. Sedimentation tanks are generally structures for separating mud and water before or after biochemical treatment, and mostly separate sludge with finer particles. Before...
