Water quality detection method

Abstract

The invention discloses a water quality detection method which includes the specific steps: reading real-time data; replacing cleaning water; performing measurement and cleaning. Compared with a traditional water quality detection method, the water quality detection method can detect various water quality data by the aid of a plurality of groups of independent electrodes, a measuring cell and the electrodes can be cleaned by clean water after water quality is detected every time, accuracy of the detected data is ensured, the measuring cell is made of transparent organic glass, electrode conditions are conveniently checked out, maintenance is facilitated, the positions of a first water pump and a second water pump can be changed at any time through a floating platform by a water pumping detection method, operation is convenient and simple, and measuring points can be conveniently replaced.

Description

technical field [0001] The invention belongs to the field of water quality detection, and more specifically relates to a water quality detection method. Background technique [0002] Water is the source of life, and human beings cannot do without water in life and production activities. Water quality testing is the process of monitoring and measuring the types of pollutants in water bodies, the concentration and change trend of various pollutants, and evaluating the water quality status. The detection range is very wide, including unpolluted and polluted natural water and various industrial drainages. The main testing items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, chroma, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing water quality detection methods generally use water quality measuring instruments to detect various water quality parameters. However, the existing water quality measuring instruments integrate the electrodes used to measure various parameters into one form. The measurement method needs to insert the water quality measuring instrument into the water body. This kind of water quality measuring instrument and detection method has the following disadvantages: 1. The maintenance cost is high, the electrodes are integrated into one body, it is inconvenient to disassemble and replace, and the state of the electrodes cannot be ascertained. Inconvenient; 2. The submerged measurement method makes the selection of measurement points more limited
