What are the operating principles and main units of a sewage purifier?

Answer:

3, after a period of operation, turn on the backwash pump for backwashing. This product has replaced the traditional agitation, flocculation, precipitation, scraping, lifting, filtration, recoil, sludge concentration and other complicated process and structure system.
1) the whole process control principle. The entire process of hospital wastewater generation, treatment and emission control. 2) the principle of minimization. Strict hospital internal health and safety management system, in the sewage and sewage generation source for strict control and separation, hospital living sewage and ward sewage collection respectively, namely source control, clean sewage diversion. The hospital sewage and dirt are not allowed to be disposed of and discharged into the sewer. 3) the principle of on-site treatment. In order to prevent the pollution and harm in the process of hospital sewage transportation, the hospital must be treated locally. 4) classification guidelines. According to the nature and scale of the hospital, the whereabouts of the sewage discharge and the regional differences, the sewage treatment of the hospital is classified and guided. 5) the combination of standards and risk control. Consider the comprehensive hospital and infectious disease hospital sewage discharge standard of the basic requirements, and strengthen the awareness of risk control, improve the ability to respond to emergencies from the technology, engineering construction supervision and management etc.. 6) ecological safety principle. Effective removal of toxic and harmful substances in sewage, reduce the disinfection by-products in the process of production and control excess chlorine in water, and protect the ecological environment safety.
Sewage purifier principle and device:1. The wastewater enters the regulating tank and is pumped into the purifier by the water pump. At the same time, the medicament and the waste water are absorbed into the pipeline by using the principle of negative pressure, and the mixture is mixed into the purifier.
2. After purification, centrifugal separation, gravity separation, dynamic filtration and sludge concentration in the purifier, the purified water is discharged from the top of the purifier, and the concentrated sludge is discharged regularly or continuously from the bottom.
