Description

Technical Field

[0001] The present application relates to the field of waste liquid treatment, and in particular to a prefabricated reagent tube waste liquid collection device. Background Art

[0002] Prefabricated reagent tubes can save analysts’ time in preparing reagents and quickly obtain accurate data. The analysis items such as COD, NH3-N, total nitrogen, total phosphorus, etc. in domestic sewage, industrial wastewater, and circulating water of sewage treatment plants and chemical enterprises are mostly measured using prefabricated reagent tubes.

[0003] In the prior art, such as Figure 3 As shown, the waste liquid in each reagent tube needs to be poured into the waste liquid cup separately, and then the reagent tube is cleaned 2-3 times to ensure that there is no reagent residue in the reagent tube, and then the waste liquid in the waste liquid cup is classified and collected in a special waste liquid bucket, and finally the waste liquid cup is cleaned. This method is time-consuming and has low processing efficiency. In addition, the main components of the COD reagent tube reaction reagent are concentrated sulfuric acid, potassium dichromate, and mercuric sulfate. The main components of the NH3-N reagent tube reaction reagent are sodium hydroxide, potassium sodium tartrate, mercuric dioxide, and potassium iodide. These reaction reagents are toxic and corrosive. When pouring the waste liquid into the waste liquid cup, it is inevitable that the waste liquid will splash and corrode the workbench, threatening the personal safety of the operator.

This embodiment can supply water to the flushing nozzle 51 through the flushing water pipe 52 to achieve spraying of flushing water.
