The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage, etc. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand, etc.; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides, etc. In order to objectively evaluate the water quality of rivers and oceans, in addition to the above monitoring items, it is sometimes necessary to measure the flow rate and flow.
