Waste water is the general term for water discharged during human activities and runoff rainwater, and it is one of the three major public hazards in nature. Waste water mainly includes domestic waste water and industrial waste water. Domestic waste water is sewage discharged by people in daily life activities. This waste water is mainly polluted by domestic waste and human excreta. Domestic waste water may not contain toxic substances, but it contains a lot of bacteria and pathogens, which is harmful.
Industrial waste water contains many toxic substances, including production materials, intermediate products, by-products, and pollutants generated during the production process that are lost with the water. Since waste water often contains a variety of substances harmful to the ecological environment, it is necessary to adopt corresponding purification measures for disposal according to the composition and concentration of pollutants in the waste water in order to allow discharge. The application of waste water analysis standards is an important reference material for analyzing the composition and content of pollutants in waste water.
Application fields
Waste water analysis: The waste water contains soluble and insoluble substances. The waste water should be separated before analysis. Insoluble substances generally do not cause serious pollution to water, and can be filtered to meet discharge standards. However, the analysis of insoluble substances is relatively more complicated. Waste water analysis standards are compounds for which the type and content of pollutants have been established. They can be directly used for chromatographic analysis standards to identify the components of waste water, which are convenient, fast, and highly accurate.
Environmental quality inspection: According to quality standards, waste water must be treated and meet the standards before it can be discharged. However, bad manufacturers will not discharge according to the standards, which will cause water source and soil pollution. During the environmental quality inspection process, the source of certain substances in the water source may be sewage. Therefore, the comparison of standards for sewage analysis can provide a more comprehensive analysis of the types and contents of various substances in the water.
