Two discharge pipes 5 are arranged at the bottom of the liquid storage tank 1, and an electromagnetic flow valve 501 is arranged on the discharge pipe 5. A pH detector 3 for inserting into a sewage treatment tank is connected to the controller 2.

A cover plate 4 is sealed and threadedly connected to the upper end of the liquid storage tank 1, and two groups of injection ports 401 corresponding to the acid liquid tank 102 and the alkali liquid tank 103 are arranged on the cover plate 4.

[0022] A dripper 502 is provided at the lower end of the discharge pipe 5, so that the discharged acid or alkali solution is added to the sewage treatment tank in a dripping manner, which saves resources better.

[0023] When using the device, the controller 2 is installed on the side of the liquid storage tank 1 to facilitate the connection between the controller 2 and the electromagnetic flow valve 501, and the liquid storage tank 1 is placed on the upper end of the sewage treatment device, and the pH detector 3 on the controller 2 is placed in the sewage treatment device to detect the pH in the sewage treatment device at all times;

[0024] When the pH detector 3 detects a change in the pH value in the sewage treatment plant, the pH value signal is transmitted to the controller, and the controller processes the pH value signal and feedback controls the corresponding electromagnetic flow valve 501, so that the electromagnetic flow valve 501 controls the amount of acid or alkali solution flowing out according to the pH value, so as to ensure the sewage treatment efficiency and make the pH value in the sewage treatment tank tend to a stable state;

[0025] It should be noted that in order to further ensure the sewage treatment effect, the operator needs to regularly comply with the pH value recorded by the controller and self-test the pH value, and at the same time add the consumed acid and alkali solution.
