All contaminated water sources of various types need to go through disinfection, sterilization and other relevant treatment processes. After that, Water Quality Monitoring Equipment can be used to conduct targeted tests on multiple indicators to evaluate the safety condition of water bodies.
River water is a widely seen raw water source in daily life, and river water quality testing serves as an important part of water treatment. For river water treatment and monitoring, identifying pollution sources before conducting treatment helps slow the outward spread of pollutants and reduce the affected area of contamination. Specific ways to trace pollution sources are affected by multiple natural and human factors, including river geographical conditions, surrounding environment, rainfall and population distribution.
Take emergency river pollution response as an example. The first task for on-site staff is to block pollutant spread, control continuous pollutant discharge from pollution sources and slow down the diffusion rate of contaminants in river water. A closed pollution control zone can also be designated. Inside the enclosed zone, standardized treatment can be carried out on polluted water, and water quality monitoring stations can be set up to track real-time water quality changes. Once the cause of water pollution is identified, relevant measures shall be adopted to lower the concentration of pollutants in the water body.
Common pollution sources include industrial wastewater and domestic sewage discharged without sufficient treatment. Proper source control can greatly ease river pollution issues. Still, source control alone cannot avoid river pollution entirely. When river pollution occurs, water purification agents can be applied to relieve pollution impacts. Another feasible solution is to pump polluted water to water treatment plants for professional disposal. After treated water meets standard requirements in all tested indicators, isolation facilities can be removed. Upstream river flow will flush and dilute residual pollutants to further lower contamination impacts.
Take water supply plants for reference. Many plants take river water as raw water, which will be transported to water supply enterprises for complete purification treatment. Drinking Water Quality Tests will be implemented afterwards. Only when all indicators meet relevant standards can treated water be delivered to residents through pipelines for daily use.
