[0002] A wastewater treatment device is a special equipment for treating various types of wastewater. The purpose of the wastewater treatment device is to purify the wastewater to meet the discharge standards or to be reused, thereby reducing environmental pollution and protecting water resources and the ecological environment. With the implementation of rural revitalization, a large number of wastewater treatment equipment have been put into use. During the use of wastewater treatment equipment, chemical agents need to be added through a chemical dosing device.
[0003] Existing technologies such as the utility model with the publication number CN211971790U disclose a supporting chemical dosing device for wastewater treatment equipment, including a wastewater treatment circulation pipeline. A group of motors are fixedly installed on the right side of the front end of the outer peripheral surface of the chemical dosing barrel. When it is necessary to add liquid medicine into the chemical dosing barrel, only four rubber fan-shaped sheets need to be turned outwards, so that the female buckles fixedly installed on the top surfaces thereof are respectively buckled and matched with the male buckles fixedly installed on the top surfaces of the four U-shaped blocks, restricting the four rubber fan-shaped sheets in the unfolded state. Since the four rubber fan-shaped sheets are all in the unfolded state, the top opening end of the chemical dosing barrel is exposed, facilitating the addition of liquid medicine. After the liquid medicine is added, only the male buckle and the female buckle need to be separated, and under the characteristic of the material of the rubber fan-shaped sheet, it will automatically rebound and re-seal the top opening end of the chemical dosing barrel together. Through the design of the structure of the utility model, the addition of liquid medicine is more convenient, solving the cumbersome steps of opening the lid of the chemical dosing barrel during traditional liquid medicine addition.
[0004] At present, most chemical dosing devices fill the liquid medicine by gravity. Due to the flow of sewage inside the wastewater treatment circulation pipeline, the filling efficiency of the liquid medicine is low. At the same time, the sewage is easily refluxed into the chemical dosing barrel through the pipeline, polluting the chemical dosing barrel and being unfavorable to the normal use of the chemical dosing device. Therefore, improvements are needed. Summary of the Utility Model

[0008] Preferably, the manifold pipe is in a circular ring shape and the manifold pipe is sleeved on the hopper.
[0009] Preferably, the spray pipe is inclined. The number of the spray pipes is seven. The seven spray pipes are arranged in a circumferential array. Before injecting the liquid medicine, the liquid medicine is added into the hopper. Then the air pump is turned on. The air pump sprays gas through the conduit and the manifold pipe and out of the spray pipes. Then the gas impacts the liquid medicine. Since the spray pipes are inclined, the liquid medicine is immediately mixed. Then the air pump is turned off.

When injecting the liquid medicine, the sealing cover is installed on the hopper. Then the valve and the air pump are turned on. The air pump flushes gas into the hopper. The liquid medicine in the hopper is injected into the sewage treatment pipe through the valve and the check valve.
[0012] Preferably, a support frame is fixedly connected to one side of the hopper. One end of the support frame away from the hopper is fixedly connected with a clamping frame, which is convenient for placing the sealing cover.
[0013] Compared with the prior art, the advantages and positive effects of the utility model are as follows:
[0014] 1. In the present utility model, before adding the liquid medicine, the liquid medicine is added into the hopper. Then, the air pump is turned on. The air pump sprays gas through the conduit and the shunt pipe and out of the spray pipe. Then, the gas impacts the liquid medicine.
