Municipal sewage treatment equipment

1.Introduction to Municipal Sewage Treatment Equipment

Municipal sewage refers to the general term for urban domestic sewage and industrial wastewater, mainly including residential sewage, commercial service area sewage, etc. The main processes for treating municipal sewage include pre-treatment, primary treatment, secondary treatment, and advanced treatment.

The pre-treatment stage includes processes such as grid removal, sand settling tank, and regulating tank, which are used to remove large particle impurities, sediment, and regulate water quality in wastewater, preventing adverse effects on subsequent treatment equipment and processes.

Primary treatment typically uses physical and chemical methods such as chemical precipitation, biodegradation, and membrane separation to remove suspended solids, suspended sediments, and some organic matter from wastewater.

The secondary treatment mainly adopts biological treatment technologies, including activated sludge method, biofilm method, and artificial wetland, to degrade organic matter and remove pollutants such as nitrification, denitrification, and phosphorus removal.

Deep treatment is mainly aimed at special industries with higher discharge or effluent requirements, using technologies such as high-density sedimentation tanks, deep bed denitrification filters, ozone biological activated carbon, etc. to achieve stricter emission standards.

2.Composition of municipal sewage treatment equipment

The composition of municipal sewage treatment equipment includes：

(1) Grille well: used to remove large suspended solids in sewage, such as plastic bags, leaves, paper, etc;

(2) Lift pump room: Lift sewage and pressurize it to lower level treatment equipment as needed;

(3) Biochemical reaction tank: usually using activated sludge method or anaerobic/aerobic process, utilizing microorganisms to decompose organic matter in wastewater;

(4) Sedimentation tank: separating suspended solids in wastewater;

(5) Disinfection equipment: Chlorine disinfection is usually used to kill bacteria and viruses, ensuring that sewage meets standards before being discharged into the environment;

(6) Filtering system: further remove residual suspended solids and other pollutants from wastewater;

(7) Electrical control system: used to control the operation and monitoring of the entire sewage treatment equipment;

(8) Instrument: used to monitor various indicators in the sewage treatment process, such as pH value, DO, temperature, pressure, etc.

3.Process characteristics of municipal sewage treatment equipment

(1) Advanced technology, effluent meets standard requirements;

(2) Intelligent control, easy to operate;

(3) Excellent removal effect and cost-effective maintenance;

(4) Provide customized services and develop treatment processes that are highly compatible with customer needs.
