Embodiment 1

[0026] Embodiment one, at first start drive motor 10, make it drive stirring paddle 16 and start to rotate, open control valve and ultraviolet sterilizing lamp 12 on the water pipe 7 simultaneously, then pass into sewage from water inlet pipe 5, sewage passes filter plate 17, The floating matter is blocked in the groove of the filter plate 17 when passing through the filter plate 17, and the sewage falls from the filter plate 17, and flows into the second treatment pool 3 from the water pipe 7, and the sewage in the second treatment pool 3 Flow from the water pipe 7 to the third treatment tank 4, when the second treatment tank 3 and the third treatment tank 4 are full of sewage, stop feeding the sewage, and the sewage is stirred by the stirring paddle 16 to make the sediment and sewage quickly Separation, and at the same time make the stirred sewage evenly receive the irradiation of the ultraviolet sterilizing lamp 12, and quickly separate and precipitate the sediment from the ...

Embodiment 2

[0027] Embodiment 2, when dealing with floating matter, when the floating matter passes through the filter plate 17, it accumulates in the groove of the filter plate 17, and during each treatment, when the sewage in the first treatment pool 2 flows to the second treatment pool 3 and After the third treatment tank 4 is inside, unscrew the screw, pull the handle 18 outwards, and filter plate 17 is extracted out. When the filter plate 17 is extracted, the tooth grooves at the bottom of the filter plate are constantly meshed with the teeth of the fixed runner 20. With the assistance of the wheel 20, read and extract quickly, then the floating matter is poured out, then the filter plate 17 is plugged back, and one side of the handle 18 is inserted with a screw to be fixed in the side wall of the first treatment pool 2.

Abstract

The invention discloses a precipitation tank for sewage treatment. The precipitation tank comprises a precipitation tank, a first treatment tank, a second treatment tank and a third treatment tank, wherein a support column is welded at the upper end of the bottom end of the interior of the precipitation tank; the first treatment tank is arranged at the upper end of the support column through an installation sheet; one side of the first treatment tank is connected to the second treatment tank through a water pipe; the bottom end of the second treatment tank is arranged at the upper end of the support column through the installation sheet; the bottom end of the support column is fixedly welded at the bottom end of the interior of the precipitation tank; the other side of the second treatmenttank is connected to the third treatment tank through a water pipe. The precipitation tank has the advantage that after treating by the first treatment tank, the second treatment tank and the third treatment tank, the sewage treatment effect is greatly improved, and the dirt content of the sewage is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sedimentation tank for sewage treatment. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow type according to the direction of water flow in the pool. Considering the flocculation factor in the process of particle settling, it is assumed that the settling velocity of the particles changes at constant acceleration, and the initial settling velocity is set to zero. Among them, the sedimentation tank is the natural sedimentation of sewage in the pool, so that the sewage in the sewage settles at the bottom of the pool, so as to facilitate collection. [0003] The Chinese invention patent with the notification number CN206799336U di...
