Inside the waste liquid treatment tank 1, there is a waste liquid treatment chamber 11. At the top of the waste liquid treatment tank 1, there are a chemical storage bin 2, a detection bin 3, and a liquid inlet bin 4. The chemical storage bin 2, the detection bin 3, and the liquid inlet bin 4 and the waste liquid treatment tank 1 can be of an integral structure or a split structure. Inside the chemical storage bin 2, there is a chemical storage chamber for storing chemicals, and the chemical storage chamber is used to store the chemicals required for waste liquid treatment. The chemicals can be alkaline liquids, acidic liquids, flocculants, etc. There are at least two chemical storage bins 2, and the chemicals stored in different chemical storage bins 2 are also different, so as to realize the treatment of different waste liquids. At the bottom of each chemical storage bin 2, there is a connection channel 21, and the connection channel 21 communicates with the waste liquid treatment chamber 11. A third control valve 22 is arranged on the connection channel 21.

[0023] In this embodiment, a liquid inlet buffer chamber 43 is arranged inside the liquid inlet chamber 4. A liquid inlet 41 is arranged on the liquid inlet chamber 4.

A pH detection element 32 is arranged in the detection chamber 31. The pH detection element 32 can detect the waste liquid to be treated. During use, the operation process is as follows:

[0025] First step, in the initial state, the second control valve 47 closes the second liquid conveying channel 45, the third control valve 22 closes the connection channel 21, the first control valve 46 opens the first liquid conveying channel 44. The waste liquid to be treated is conveyed into the liquid inlet buffer chamber 43 through the liquid inlet 41. The filter element 42 in the liquid inlet buffer chamber 43 treats the waste liquid. The waste liquid after filtration treatment is conveyed into the detection chamber 31 through the first liquid conveying channel 44, and the pH detection element 32 detects the pH value of the waste liquid.

[0026] Second step, after the pH detection element 32 finishes detection, the first control valve 46 closes the first liquid conveying channel 44, the second control valve 47 opens the second liquid conveying channel 45, and continues to convey the waste liquid. At this time, the waste liquid after filtration treatment is conveyed into the waste liquid treatment chamber 11. When the waste liquid in the waste liquid treatment chamber 11 reaches the preset amount, the conveying is stopped.

[0027] In the third step, according to the pH value detected by the pH detection component 32 for the waste liquid, the third control valve 22 is correspondingly opened, so that the medicament stored in the medicament storage bin 2 is transported into the waste liquid treatment chamber 11 to treat the waste liquid. If the waste liquid is detected to be acidic, alkaline liquid or flocculant, etc. is transported through the medicament storage bin 2 to treat the waste liquid. If the waste liquid is detected to be alkaline, acidic liquid or flocculant, etc. is transported through the medicament storage bin 2 to treat the waste liquid.
