Description

Technical Field

[0002] Water quality monitoring is the process of monitoring and measuring the types, concentrations, and changing trends of pollutants in water bodies to evaluate water quality. The monitoring scope is very broad, encompassing both unpolluted and polluted natural waters (rivers, lakes, oceans, and groundwater) as well as various industrial wastewaters. Key monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other is the presence of toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury, and organic pesticides. In addition to the aforementioned monitoring items, flow velocity and flow measurement are sometimes necessary to objectively assess the quality of river and ocean water.

The water drawn out of the water supply pipe flows slowly or even does not flow. Water quality monitoring cannot obtain real-time and accurate monitoring results. In addition, the existing monitoring devices are mostly not easy to disassemble after installation, which brings certain inconveniences to users when they conduct maintenance in the later stage.
