Abstract

The invention discloses a sedimentation tank suitable for treating sewage with high suspended solids. The sedimentation tank comprises: a tank body provided with a water inlet, a water outlet and a sludge discharge port; a plurality of sludge hoppers distributed at the bottom of the tank body in an array manner; an inclined pipe arranged in the middle of the tank body; and a plurality of water inlet pipes respectively communicated with the water inlet, wherein each water inlet pipe corresponds to one sludge hopper, and the water outlets of the water inlet pipes are positioned below the inclined pipe. The sedimentation tank can effectively improve the treatment efficiency of sewage with high suspended solids (ss) and other indexes, avoid the disturbance of a supernatant to the sludge sedimentation process, increase the sludge settling speed, avoid secondary disturbance of sludge, easily clean the water inlet pipes from the top ends when the water inlet pipes are blocked, and improve thesludge discharge efficiency.

Description

technical field

[0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a sedimentation tank suitable for sewage treatment with high suspended matter. Background technique

[0002] With the accelerated pace of life, water pollution is becoming more and more serious, and sewage treatment and reuse are becoming more and more necessary. In the sewage treatment process, the vertical flow sedimentation tank is widely used due to its small footprint and good sludge discharge efficiency. When there is a problem of disturbance to the settled sludge, the sedimentation effect is not ideal.

[0003] Therefore, in view of the above technical problems, it is necessary to provide a sedimentation tank suitable for sewage treatment with high suspended solids, which can improve the efficiency of sewage treatment and avoid disturbance of the supernatant to the settled sludge.
