Abstract

A sewage treatment system belongs to the field of environmental protection and aims to achieve the purpose of comprehensively utilizing sewage in schools. The sewage treatment system mainly comprisesa gathering system, a precipitation system, a filtering system, a grading system, a disinfection system, a mechanical pressurization system and a circulating water system; the disinfection system is provided with a quicklime treating agent, and the filtering system adopts a mechanical pressurizing filtering mode. When the sewage treatment system is used, sewage generated by washing, canteens and the like is gathered to the gathering system and naturally precipitates in the precipitation system, solid wastes are removed, the obtained liquid flows into the grading system, the obtained solid is mechanically pressurized and filtered through the filtering system, the obtained liquid flows into the grading system, the obtained solid is landfilled, the liquid flowing into the grading system is graded, a part of the liquid is used for irrigation, a part of the liquid flows into the disinfection system, and is disinfected with quicklime to kill bacteria and viruses to form usable circulating water, and the usable circulating water is input into the mechanical pressurization system to be prepared for use through the circulating water system. The sewage treatment system has the advantages ofreasonable structure, high treatment efficiency and simplicity, and is mainly applicable to closed schools.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a sewage treatment system. Background technique [0002] Fresh water is a very precious material, which is related to national development and people's life and health. Our country is extremely scarce in resources, and the per capita ownership ranks low in the world. But in daily life, the waste of fresh water is very serious. There is a serious water waste phenomenon in schools, and the loss is very huge. However, it is very feasible to use the characteristics of the school for recycling. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a sewage treatment system to achieve the purpose of comprehensively utilizing sewage in schools. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: the sewage treatment system is mainly composed o...
