The water environment protection work is continuously promoted and achieves certain effect, but the environment protection mechanism still needs to be further improved in the actual work. Water quality testing work is carried out, water quality testing work can also be carried out and detailed understanding can be carried out on indexes such as pollutant categories and concentrations in the water, the water pollution condition can be known in time, pollution sources are clear, effective reference basis is provided for later-stage water quality condition understanding and treatment work development, water resource pollutants are removed in time, and the water resource quality is effectively improved. At present, the water quality detection in China has a wide working range and comprises water sources such as natural water, rivers, lakes, underground water and the like. The water quality detection indexes mainly comprise indexes such as the content, chromaticity, oil content, COD (chemical oxygen demand), BOD (biochemical oxygen demand) and the like of the combined pollutants in the water body, and the water quality detection work is to scientifically evaluate the water quality of daily water. The hydrological conditions of all regions can be objectively known, the quality of the existing water resource can be reasonably evaluated, and the method has a positive promoting effect on the water environment protection work.
The quality of the water quality detecting instrument directly influences the accuracy of the water quality detecting result, and the stability of the water quality detecting instrument can obviously influence the quality control in the actual work of water quality detection. A novel rapid detection device for sewage quality pretreatment is introduced in the patent CN112505274A, can detect sewage in different layers in real time, and effectively improves the quality of sewage detection by adopting a hierarchical detection mode. However, when the sewage quality is actually detected, the impurity components in the sewage can block the devices for detecting the water quality, and further cause the error of the detection result. Therefore, the problem of researching how to improve the result accuracy of the detection equipment and reduce the accumulation of impurities in devices in the water quality detection equipment is a problem.
