Abstract

The utility model relates to a four-section medical sewage treater. The first section of the sewage treatment process is to collect all the medical sewage into a collecting basin; the second section thereof is to perform aerobic reaction in a first reaction tank and a second reaction tank to the sewage collected in the collecting basin, so as to decrease the content of pollutant and meet the requirement on discharging; the third section thereof is to filter water in a pipe membrane filter; and the fourth section thereof is to pump bactericide (sodium hypochlorite drug) water in a drug storage tank into a sterilizing tank for sterilization through a metering pump, and discharge the treated sewage into an urban sewage drain after reaching the Discharge Standard of Water Pollutants for Medical Organization regulated by the nation.

Description

The four-part form medical sewage treater

Technical field the utility model relates to the water treating equipment field, the concrete four-part form medical sewage treater that relates to

Background technology China has implemented new standard " Discharge standard of water pollutants for medical organization " on January 1st, 2006.It is reported that new standard is higher, more perfect than original standard to the requirement of aspects such as biological indicator.By carrying out new standard, infectious hospital can cut down COD70%, and BOD cuts down 80%, and SS cuts down 80%.General hospital polyclinic cuts down COD50%, and BOD cuts down 60%, and SS cuts down 60%.Along with the development of China's medical industry, every day is discharged large amount of sewage by medical institutions, and these sewage may contain infectivity cause of disease bacterium, virus, chemical pollutant and radioactive substance, will cause environment and HUMAN HEALTH and have a strong impact on as not adding control.Medical sewage except containing pollutents such as COD, BOD, be the more important thing is and contained a large amount of pathogenic bacterium.Hospital sewage is through post precipitation, has the worm egg of 70～80% germ, virus and 90% to transfer in the mud.Therefore, traditional treatment process is that sewage, the mud of septic tank and discharging are disinfected effectively.Lazaretto ward and infectious hospital must be provided with the customizations manure pit.Year draw once clearly septic tank mud every half a year to one.Reply septic tank mud is monitored during clear washing in a pan.The induced worm egg death rate of septic tank and sewage works mud and excrement colibacillus group number should reach respectively＞95% and≤requirement of 100MPN/g, mud up to standard is delivered to special Disposal sites disposal or is carried out burning disposal by specialised vehicles, has caused the waste of great human and material resources and financial resources.That have even handle not thoroughly, cause the hidden danger of pathophoresis for the second time.

The summary of the invention the purpose of this utility model is the deficiency of handling at above medical sewage, has proposed a kind of four-part form medical sewage treater of thorough processing medical sewage, can save great amount of manpower and material resources and financial resources.

The utility model is made up of water collecting basin, the first aerobic reaction pond, the second aerobic reaction tank, intermediate pool, tubular membrane strainer, storage medicine pond, sterilization pond and volume pump.

Be divided into four sections operations and handle, first section is that medical sewage is all focused on water collecting basin; Second section is that the sewage that will concentrate on water collecting basin carries out aerobic reaction through the first aerobic reaction pond, the second aerobic reaction tank, reduces pollutant load, reaches emission request; The 3rd section is with the tubular membrane strainer waterpower to be handled; The 4th section is to enter the municipal effluent network of drains with the sterilization of clorox medicine after " Discharge standard of water pollutants for medical organization " that reach national regulation.

Description of drawings

Fig. 2 is the utility model sewage disposal operation simplified schematic diagram

Embodiment is in the three-dimensional simplified schematic diagram of four-part form medical sewage treater shown in Figure 1, and the utility model is made up of water collecting basin 1, the first aerobic reaction pond, 2, the second aerobic reaction tank 3, intermediate pool 4, tubular membrane strainer 5, storage medicine pond 6, sterilization pond 7 and volume pump 8.Water collecting basin 1 is underground 9 parts, allows as the place, should be square pond; Other four ponds are conjuncted rectangle pond, and with the welding of U-pvc plate, volume pump 8 is installed in above " ten " word support plate; Pipe network connects with the U-pvc pipe fitting.

Except the rectangular pond body of selecting disjunctor, also can adopt second-hand U-pvc bucket to connect the back and use, not disjunctor.

In four-part form medical sewage treater sewage disposal operation simplified schematic diagram shown in Figure 2, the sewage disposal operation is for first section that medical sewage is all focused on water collecting basin 1; Second section is will concentrate on the sewage of water collecting basin 1 through carrying out aerobic reaction in 2, the second aerobic reaction tank 3 of the first aerobic reaction pond, and the reduction pollutant load reaches emission request; The 3rd section is with tubular membrane strainer 5 sewage to be handled in intermediate pool; The 4th section is that the bactericide (clorox medicine) in the storage medicine pond 6 is evacuated to sterilization in the sterilization pond 7 with volume pump 8, after " Discharge standard of water pollutants for medical organization " that reach national regulation, the sewage of handling is entered the municipal effluent network of drains.

The size of each pond body can calculate according to hydraulic detention time according to concrete needs design, and the hydraulic detention time in each step sees table.

Each goes on foot hydraulic detention time

Sequence number	Pond body title	Hydraulic detention time (hour)
Sequence number	Pond body title	Hydraulic detention time (hour)	1	Water collecting basin	12
2	The first aerobic reaction pond	3	1	Water collecting basin	12
2	The first aerobic reaction pond	3	3	The second aerobic reaction tank	3
4	Intermediate pool	3	3	The second aerobic reaction tank	3
