Technical Field

The utility model relates to a sewage treatment technical field especially relates to a sewage treatment system.

Background

The vatch well is a well in which contaminated cellar wells are collected, and which leads to a sewage treatment plant, and if there is no such well, each pipe leading to a dwelling or other sewage discharge must be connected directly to the sewage treatment plant in order for sewage to enter the sewage treatment plant. In the front, a well is used for intercepting the sewage, a pipeline is directly communicated from the intercepting well to discharge the sewage to a sewage treatment plant, the pipelines from the sewage treatment plant are greatly reduced, and the sewage collection is also facilitated.

The current vatch basin includes the well body and with the blow off pipe of well body intercommunication, blow off pipe and sewage treatment plant intercommunication, the top and the ground intercommunication of the well body, the well body still communicates there is the downspout, downspout and river course intercommunication, the level of downspout is higher than the level of blow off pipe, the purpose of downspout design is mainly, because the pollutant that the rainwater in middle and later stage contains is comparatively few, can directly arrange to the river course in not handling, so that when heavy rain, in the rainwater in middle and later stage can be arranged the river course from the downspout, the burden of blow off pipe and sewage treatment plant has been alleviateed.

The above prior art solutions have the following drawbacks: when the rainwater in the middle and later periods is drained from the rainwater pipe, the drain pipe is in a state communicated with the well body, so that the rainwater in the middle and later periods is also partially drained to a sewage treatment plant from the sewage discharge pipe, the treatment burden of the sewage treatment plant is increased, and the improvement needs to be carried out on the rainwater.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a sewage treatment system which can reduce the burden of sewage treatment in sewage treatment plants.

The above object of the present invention can be achieved by the following technical solutions:

the utility model provides a sewage treatment system, includes the well body, well body intercommunication has downspout and sewage pipe, the level of downspout is higher than the level of sewage pipe, the sewage pipe is equipped with the board that cuts that opens and shuts the sewage pipe, be equipped with the drive assembly that the drive cut board moved on the well body.

Through adopting above-mentioned technical scheme, when heavy rain, after the rainwater reachd middle and later stage rainwater, drive assembly drive closure plate shutoff is at the sewage pipe to make the rainwater of middle and later stage be difficult for arranging to sewage treatment plant from sewage pipe department, alleviateed sewage treatment plant's the burden of handling sewage, the rainwater of middle and later stage passes through the rainwater pipe and arranges to the river course in, supplements the river, with the discharge of having richened the river course. The horizontal position through setting up the downspout is higher than the level of sewage pipe to make earlier stage's the sewage of discharging and earlier stage rainwater can follow the sewage pipe earlier and drain away, so that carry out centralized processing to sewage and earlier stage rainwater at sewage treatment plant.

The present invention may be further configured in a preferred embodiment as: the cutoff plate is located at the communication position of the sewage pipe and the well body, the cutoff plate is connected with the inner wall of the well body in a sliding mode, and a limiting piece for limiting the cutoff plate to be separated from the well body is arranged on the inner side wall of the well body.
