[0002] Urban residents generate a large amount of garbage and sewage in their comfortable lives, which must be treated promptly and efficiently to prevent pollution and ensure the stable operation of society. Wastewater treatment technology requires multiple stages to ensure treatment effectiveness. Among these, sedimentation tanks are used to remove impurities and particulate matter from the sewage to ensure they do not affect subsequent treatment processes.

[0003] Existing sedimentation tanks for wastewater treatment still have some shortcomings. Most of them do not have the function of quantitative addition of coagulants. The coagulants are mainly added by staff based on experience, which can easily lead to waste of coagulants. Therefore, we propose a sedimentation tank for wastewater treatment. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The system is equipped with a storage tank, connecting pipe, flow meter, metering tank, level gauge, and solenoid valve to achieve quantitative addition of coagulant. The coagulant inside the storage tank enters the metering tank through the connecting pipe. The flow meter can measure the amount of coagulant flowing through the connecting pipe, thereby controlling the amount of coagulant and avoiding waste.

[0012] 2. The system is equipped with a motor, a rotating shaft, and stirring blades, which enable the mixing of wastewater and coagulant. When the motor is started, the rotating shaft rotates, which in turn drives the stirring blades to mix the wastewater and coagulant, thus increasing the mixing speed. Attached Figure Description
