JD-LSZ05 Water is the source of life, protecting water resources and maintaining water quality is related to everyone's health and life. How to ensure water quality safety? Water quality monitoring is an indispensable task. Let's take a look at the relevant content of water quality monitoring.
1. Monitoring content.
Water quality monitoring mainly includes three aspects: water quality indicators, water pollutants, and water functional zoning. Water quality indicators include dissolved oxygen, pH value, ammonia nitrogen, etc., which are the basis for judging whether the water quality meets the standard. Water pollutants mainly refer to chemical pollutants, biological pollutants, etc., which are the key to judging the degree of water pollution. The functional zoning of water bodies is based on the water quality, quantity and other factors of the water body, which are divided into different functional areas, such as drinking water protection areas and ecological reserves.
Second, the monitoring method.
Water quality monitoring is mainly divided into on-site monitoring and laboratory monitoring. On-site monitoring refers to the collection of water samples in water bodies and testing them through on-site analytical instruments; Laboratory monitoring involves bringing the collected water samples back to the laboratory for analysis. The two monitoring methods have their own advantages and disadvantages, and the on-site monitoring response speed is fast, but the accuracy is relatively low. Laboratory monitoring accuracy is high, but resource costs such as time are high.
3. Monitoring Bodies.
Water quality monitoring is a highly professional work, which requires professional institutions to monitor. At present, China has established a sound water quality monitoring network, and the national environmental protection department and local governments at all levels have set up special institutions to monitor water quality.
Water quality monitoring is an important task to maintain the health of water bodies, and we hope that everyone can strengthen their attention to water quality monitoring and jointly protect the healthy water sources around them.
