Water is the basis of everything. In recent years, the whole society attaches more and more importance to ecological environmental protection, "gold and silver mountains is not as good as green water and green mountains" to our awareness of ecological protection once again sounded the alarm.
Where there is water, there is water quality monitoring, especially domestic wastewater, industrial effluent and surface water. Not only to achieve 24-hour continuous monitoring, but also scientifically and effectively control the monitoring of the quality of the water body does not meet the standard, and then discharged and used. So water quality monitoring is particularly important.
What is water quality monitoring?
Water quality monitoring refers to the compounds in the water, floating matter, silt and water ecosystems to focus on regular or irregular testing, monitoring and testing of water quality in the pollutant categories, concentration values and change patterns, evaluation of water quality conditions and other work.
Water quality monitoring projects are divided into two categories: one is a comprehensive indicator of water quality conditions, such as: temperature, colour, turbidity, pH, conductivity, conflation, dissolved oxygen, chemical oxygen demand and biological oxygen demand, etc.; the other is a part of the harmful substances, such as: phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides, etc..
Water quality monitoring a wide range, including natural water (rivers, streams, lakes, oceans and groundwater) and a variety of industrial drainage.

There are several purposes of water quality monitoring:
There are two types of water quality monitoring, namely environmental water quality monitoring and water pollution source monitoring. Environmental water quality monitoring of groundwater and surface water; water pollution source monitoring of hospital wastewater, domestic wastewater and so on.
(1) Regular monitoring of pollutants entering surface water bodies such as rivers, streams, lakes, reservoirs and oceans, and pollutants seeping into groundwater, in order to keep track of the quality status of the water body and its development trend.
(2) Monitor various wastewater discharged from production processes, living facilities and other emission sources to provide a basis for pollution source management and discharge charges.
(3) Carry out emergency monitoring of water environment pollution accidents, providing the basis for in-depth analysis of causes, hazards and response strategies.
(4) Provide relevant data and information for our governmental agencies to formulate ecological environmental protection regulations, standards and planning, and to carry out comprehensive environmental protection management.
(5) Provide basic data and means to carry out water environment quality assessment, prediction and environmental scientific research.
The significance of water quality monitoring
Environmental monitoring is the main work of water quality monitoring, accurate, early, all-round reflection of the water quality status and development trend, for water environment management, pollution control, urban ecological planning to provide a scientific basis for the whole water environment protection, water pollution control and water environment health maintenance plays an important role.
