Domestic sewage treatment refers to the treatment of wastewater generated in human life to reduce environmental pollution and protect human health. Domestic sewage mainly includes wastewater generated from households, schools, hospitals, restaurants, and other places, which contains a large amount of organic matter, suspended solids, nutrients, and microorganisms. If these untreated sewage are directly discharged into natural water bodies, it will have a serious impact on the water environment and ecosystem.
In order to effectively treat domestic sewage, a series of treatment processes and equipment need to be adopted. Common domestic sewage treatment processes include physical treatment, chemical treatment, and biological treatment. Physical treatment mainly removes suspended solids and solid particles through methods such as precipitation, filtration, and adsorption; Chemical treatment mainly involves adding chemical agents for coagulation, precipitation, and oxidation reactions to remove organic matter and nutrients; Biological treatment mainly converts organic matter and ammonia nitrogen into harmless substances through the degradation of microorganisms.
The equipment for domestic sewage treatment includes grilles, sedimentation tanks, regulating tanks, aeration tanks, sedimentation tanks, filters, and disinfection equipment. Grille is used to remove large particle impurities from sewage; The sedimentation tank is used to remove sand particles and stones from wastewater; The regulating pool is used to balance the water quantity and quality entering the treatment system; Aeration tanks are used to provide oxygen supply for microbial degradation reactions; Sedimentation tanks are used for settling and removing suspended solids from wastewater; The filter is used for further removal of suspended solids and organic matter; Disinfection equipment is used to kill bacteria and viruses in wastewater.
In the process of domestic sewage treatment, the following points need to be noted:
1. Design reasonable treatment processes and equipment to ensure effective removal of pollutants from wastewater;
2. Control the operating parameters during the treatment process, such as aeration rate, aeration time, sludge concentration, etc., to achieve the best treatment effect;
3. Regularly inspect and maintain the processing equipment to ensure its normal operation;
4. The treated sludge should be properly treated and disposed of to prevent secondary pollution;
5. Monitor the treatment effect to ensure that the effluent quality meets national and local discharge standards.
