Embodiment 1

[0041] refer to Figure 1-5 As shown, this embodiment provides a sedimentation tank suitable for sewage treatment with high suspended solids, including a tank body 1, a sludge bucket 2 arranged in an array at the bottom of the tank body 1, and an overflow plate arranged at the top of the tank body 1 3. The slope 4 set in the middle of the pool body 1 and the water inlet pipe 5 set inside the pool body 1 .

[0042] The pool body 1 is made of Q235B steel plate with a thickness of 10mm. The inner wall of the pool body 1 is anti-corrosion with epoxy coal tar pitch. The outer wall of the pool body 1 is anti-corrosion with two bottoms and one middle and two sides. The paint adopts epoxy ester topcoat. The two sides of the pool body 1 are provided with a water inlet 11 and a water outlet 12 respectively. The height of 13 is lower than water inlet 11 and water outlet 12, is positioned at the middle part of pool body 1, and the bottom of pool body 1 is provided with support leg 14, an...

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. Contents of the invention [0004] The object of the prese...
