It can be understood that the overflow box 32 can be made of plastic material, which can not only prevent the sewage from corroding the overflow box 32, but also reduce the weight of the overflow box 32, and the required buoyancy is smaller, thereby making the size of the first floating plate 33 smaller. Small.

In the embodiment of the present application, by injecting sewage into the sediment pretreatment assembly 3, the floating matter and large particle sediment in the sewage are left in the overflow tank 32, and the pretreated sewage flows into the sedimentation tank 1 Sedimentation is carried out, and the settled sewage is discharged through the drainage assembly 4. The drainage assembly 4 follows the sediment pretreatment assembly 3 and floats on the upper water surface of the sedimentation tank 1, which can effectively avoid the agitation of the sediment at the bottom and improve the separation efficiency.

In addition, when the sewage in the sedimentation tank 1 is pumped out, the drainage assembly 4 and the sediment pretreatment assembly 3 follow the water level to descend, and the drainage assembly 4 keeps sucking the upper water surface in the sedimentation tank 1, which does not require real-time operation by staff, and is more convenient. It is simple, and the workload is more convenient and less than manual suction.

When the sewage plant needs to treat the sewage, it means separating the sewage after sedimentation.

Specifically, as shown in Fig. 3 and Fig. 5, the relevant staff connects the water inlet pipe 34 to the sewage treatment place, which can be the sewage source pool of the sewage plant, (the sewage source pool, which is used to store untreated treated sewage pool), and the sewage is pumped into the overflow tank 32 by the water inlet pipe 34 through the water pump. As the sewage in the overflow tank 32 increases until it overflows the filter plate 35, the floating water in the sewage The sediment and large particle sediment are blocked by the filter plate 35, and the pretreated sewage finally overflows the overflow tank 32 and flows into the sedimentation tank 1. The sewage is filtered by the sediment pretreatment component 3 to remove the large particle in the sewage (comprising sediment, floating matter and floc, etc.) are blocked in the overflow box 32, and the sewage has been preliminarily filtered.

Along with more and more pretreated sewage in the sedimentation tank 1, the overflow box 32 floats under the buoyancy effect of the first floating plate 33, and the connector 321 on the overflow box 32 floats along the first column 31, keeping The overflow tank 32 is always in a floating state.

Then, as shown in Figure 4, the relevant staff puts a precipitant or flocculant into the sedimentation tank 1 to make the pretreated sewage settle down, and after the sewage in the sedimentation tank 1 is left to stand, the relevant staff through the external The water pump sucks the water in the sedimentation tank 1 from the drainage pipe 43, and the extracted sewage can be used for deep purification of the sewage plant.

As the water level in the sedimentation tank 1 decreases, the sediment pretreatment assembly 3 drops with the water level, and the drainage assembly 4 descends with the sediment pretreatment assembly 3, and the second floating plate 42 moves on the second column 41 following the water level, always maintaining The pumping end of the drainage pipe 43 sucks the upper water surface, so that the sediment at the bottom of the sedimentation tank 1 will not be stirred, and the separation efficiency of sewage and sediment is higher.

It can be understood that the end of the drain pipe 43 close to the second floating plate 42 can be provided with an adsorption cover, and a filter can be provided in the adsorption cover to further filter the residual floating matter in the sewage in the sedimentation tank 1 .
