The processing process of sewage turning water usually requires multiple steps and methods. The following are some common sewage treatment methods, which can help sewage become clear water:
Physical treatment: Physical treatment remove solid suspension, sediments and floating objects through filtering, precipitation, stirring and other methods. Common physical treatment methods include grille, sand tank, sedimentation tank, filter, etc.
Bio -treatment: Bio -treatment uses microbial degradation organic substances and pollutants such as nitrogen and phosphorus to transform it into harmless substances. Common biological treatment methods include activated sludge methods, anaerobic digestion, and artificial wetlands.
Chemical treatment: Chemical treatment uses chemical agents to concrete and sedimentary suspension, colloidal, and organic matter in sewage. Common chemical treatment methods include the addition of coagulants and the use of oxidants.
Membrane separation technology: Membrane separation technology includes ultrafiltration and reverse osmosis. It can be separated from the filtering of the membrane to separate the sewage, dissolved objects, and microorganisms in the sewage to obtain water.
Advanced oxidation technology: Advanced oxidation technology uses strong oxidants (such as ozone and hydrogen peroxide) to break down organic substances and particle pollutants. Common advanced oxidation technologies include ozone oxidation and ultraviolet light oxidation.
It should be noted that different sewage sources and treatment requirements may need to use different treatment methods or combinations of multiple methods. In addition, sewage treatment is a complex project that involves problems in equipment, technology and operation management. Therefore, the fastest sewage treatment method depends on specific conditions and resource investment. In practical applications, in accordance with local conditions and regulations, we should comprehensively consider technology, economic and environmental factors, and choose the appropriate sewage treatment method.
