The main purpose of sewage water quality monitoring

The scope of water quality monitoring is very wide, including regular surface and groundwater monitoring, surveillance production and living process monitoring, and emergency accident monitoring. So what is the main purpose of sewage water quality monitoring? In this chapter, the editor will give you a simple explanation. Sewage water quality monitoring can provide data and information for environmental management, and for evaluating the water quality of rivers and oceans. Specifically divided into the following situations: 1. Regular monitoring of pollutants in surface water and groundwater such as rivers, rivers, lakes, reservoirs, canals, seawater, etc., to grasp the current status of water quality and its changing trend. 2. Carry out surveillance monitoring of waste (sewage) water discharged from waste (sewage) water discharge sources such as production and life, grasp the discharge volume of waste (sewage) water, its pollutant concentration and total discharge, and evaluate whether it meets the discharge requirements. Standards provide a basis for pollution source management. 4. Carry out emergency monitoring of water pollution accidents to provide a basis for analyzing and judging the causes and hazards of accidents and formulating countermeasures. 5. Provide relevant data and information for government departments to formulate water pollution protection standards, regulations, and plans. 6. To provide basic data and technical means for water environment quality assessment and prediction, forecasting and environmental scientific research. 7. Arbitrate and monitor environmental pollution disputes to provide scientific basis for judging the causes of disputes. Generally speaking, there are two main aspects: first, to understand the quality of sewage water and provide a basis for sewage treatment technical solutions. Because the description and definition of a kind of sewage is mainly from the perspective of its conventional water quality indicators, which contain the basic characteristics and information of sewage. Can be selected as a routine indicator, has its importance and significance (or environmental requirements, or very important in the treatment process, or the country has relevant emission regulations, etc.). The water quality characteristics of sewage determine which treatment method it is suitable for, and conventional indicators provide the most basic and important basis. Second, provide reference for water treatment process operation. Taking biological treatment of wastewater as an example, each process unit has relevant requirements for influent water quality, and the effluent water quality must also meet the design effect, so it is necessary to test the sewage water quality at each process node, and use this to judge whether the operation is normal. Abnormalities can also be predicted from water quality indicators. In general, routine water quality monitoring is used to reflect the basic characteristics of water quality. Provide quantitative indicators for administrative, economic and technical characterization of sewage.
