Embodiment Construction

[0060] The present invention will be further described in detail below in conjunction with specific examples, but the implementation of the present invention is not limited thereto.

[0061] see Figure 1-Figure 11 As shown, the present invention provides a high-efficiency sedimentation tank for multiple filtration sewage treatment, which includes a tank body 1, a sludge filter part, a filter pressure part, a tank top sealing plate 4, a motor 5, a water inlet pipeline 6, a sewage discharge assembly and drainage pool.

[0062] see Figure 1-Figure 3 , the pool body 1 is formed by four facades 11, 12, 13, 14 enclosing a bottom surface 15; wherein, the bottom of the left facade 11 is provided with a left drain 111, and the bottom of the right facade 12 is provided with There is a right drain 121, and the middle part of the bottom surface 15 has a sinking tank 151 for collecting sludge. The sinking tank 151 is composed of two downward slopes 1511 and a horizontal tank bottom 151...

Abstract

The invention discloses a multi-filtration sewage treatment efficient sedimentation tank. The sedimentation tank comprises a tank body, a sludge filtration part, a filtration pressure applying part, amotor, a water feeding pipeline, a sewage discharge assembly and a water discharge tank, wherein the tank body is used for accommodating sewage, the sludge filtration part is used for filtering sewage; the filtration pressure applying part is used for extruding the sewage in the tank body, and the sewage can be extruded from left and right sides and the upper side in reciprocating manner to accelerate the drainage speed of filtered water; the motor is used for providing power for extruding the sewage; the water feeding pipeline is used for supplying the sewage into the tank body, the sewage discharge assembly is used for discharging sludge deposited at the bottom of the tank body, and the water discharge tank is used for further precipitating the water discharged from the tank body. An original passive sedimentation method depending on gravity is changed, sedimentation of sludge and discharging of clear water are accelerated through continuous reciprocating extrusion of the filtrationpressure applying part, and the sludge can be rapidly collected and deposited at the bottom of the tank body and then pumped away by the sewage discharge assembly.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sedimentation tank for sewage treatment. Background technique [0002] Sedimentation tanks are often used in foundation pit engineering to settle the accumulated water on the site. Its function is to settle the sludge and sand particles in the water, so that the water can be purified to a certain extent, and then discharged into the municipal drainage system. [0003] In the current sedimentation tank, sludge and sand are settled naturally by gravity, which belongs to passive settlement. Due to the natural settlement by gravity, the settlement speed is slow and the settlement time is long, and the discharged clear water is also discharged naturally without any power, so the drainage speed is relatively slow. [0004] At present, this kind of passive sedimentation tank is a very common sedimentation tank, which is often seen in construction sites of various tunnels and subways. ...
