[0044] see Figure 1 to Figure 10 , the embodiment of the present invention proposes a first embodiment of a sewage sedimentation system. The sewage sedimentation system includes a sedimentation box 110, a water inlet pipe 120, a flow blocking channel 210, a flow blocking plate 220, a drain pipe 130, a partition 140, a floating Slag salvage mechanism 300 and sewage pipe 150.

[0045] The settling box 110 has a settling cavity 101 for containing domestic sewage. The settling cavity 101 has an upward first opening 101a. The settling box 110 has an inclined settling side wall 111 and a horizontal settling bottom wall 112. The settling side wall 111 is connected to the edge of the precipitation bottom wall 112, and the cross-sectional area of ​​the precipitation chamber 101 gradually increases from bottom to top.

[0046] The water inlet pipe 120 communicates with the sedimentation chamber 101 through the sedimentation side wall 111, the water inlet pipe 120 is used to input dome...

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage precipitation system. The sewage precipitation system comprises a precipitation tank body, a water inlet pipe, a flow resisting channel, a flow resisting plate, a drain pipe, a baffle plate, a scum fishing mechanism and a blow-off pipe, wherein the scum fishing mechanism comprises a pumping part, a conveying part, a water receiving groove and a flow guide pipe. In the embodiment of the invention, the scum fishing mechanism is arranged in the sewage precipitation system, so that scum on the water surface of a precipitation cavity can be fished and conveyed out of the precipitation tank body, and the scum in the precipitation cavity is prevented from flowing towards the drain pipe.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of sewage treatment, in particular to a sewage sedimentation system for domestic sewage treatment. [0003] 【Background technique】 [0004] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for drainage or reuse. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Domestic sewage treatment generally includes steps such as filtration and sedimentation. Sedimentation is the process by which the suspended sinkable solids in sewage sink under the action of gravity. [0005] The sewage flowing out from the water inlet in the existing domestic sewage sedimentation device includes sedimentable suspended solids and floatable scum, and the existing domestic sewage sedimentation system cannot remove the scum in the sedimentation tank. [0006] 【Content of i...
