Abstract
The utility model discloses a diffusionless total-enclosed hospital sewage treatment device with sterilization disinfection and preventing germ diffusion, belonging to the sewage treatment equipment field. The utility model comprises a closed grille, a balancing tank, a highly efficient film biological reactor, and a highly efficient wide-spectrum ultraviolet sterilizer, which are all serially connected. The device adopts a totally enclosed structure with simple assembling, convenient operation, and good processing effect. All the gas discharged from the film biological reactor, the balancing tank, and the grille is collected into the single ultraviolet sterilizer to be disinfected through a pipeline, which the outward diffusion of the germ is prevented through the gas. The output of the film biological reactor is quite small without sludge emission, which eliminates interference caused by suspended substance to the ultraviolet disinfection in the waste water and fully develops the high-efficiency function of the ultraviolet disinfection with largely reducing the probability of diffusion and rampancy of the se-producing germ through sludge emission. After processing, various indexes of the yielding water all reach or are better than the emission standard GBJ48-83 specified by the country to the hospital sludge.
Description
Technical field
The utility model belongs to the sewage disposal device scope, particularly has a kind of fully-closed hospital sewage treating apparatus of not having diffusion that sterilization and disinfection prevents proliferation of germs.
Background technology
Hospital sewage source and complicated component, hazardness is big, contains a large amount of pathogenetic bacterias, virus and chemical agent in the sewage, has the feature of space-pollution, acute infection and latent infection.If contain the hospital sewage of cause of disease micronic dust thing, enter urban sewage pipeline or environment water without disinfecting discharging, tend to cause the pollution of water body, cause various diseases and transmissible disease, the serious harm people's is healthy.Existing conventional Hospital Sewage Treatment is generally the one-level materialization and handles and add the chlorination sterilization, or secondary biochemical treatment adds the chlorination sterilization, has a lot of problems aspect hygienic safety.Because hospital sewage water quality is special, conventional aerobe treatment system does not have the sealing measure, the bubble that aeration oxygen supply process produces has diffuseed to form a large amount of aerosol molecules, these aerosol macromole surface attachment some pathogenic micro-organisms, diffusion is propagated in air, this causes the severe contamination to air with regard to having opened another passage for the propagation of infectivity eqpidemic disease; Cholorination method commonly used has very strong toxic side effect and secondary pollution problem in the hospital wastewater treating processes at present, the excessive dechlorination system that also needs necessity of dosage, and ozone, the less sterilizing agent of dioxide peroxide toxic side effect have limited large-scale use owing to its high expense, and therefore no matter the sterilisation system in the existing Hospital Sewage Treatment is that the sterilisation effect or the economic rationality aspect of operation are all desirable not to the utmost.The particularly effective control that spreads for similar " SARS " this height respiratory tract acute infectious disease, original system is worthless.At existing patent documentation: buried unpowered Hospital Sewage Treatment equipment 96220159.6, handle the novel appts 91214463.7 of hospital sewage, disinfection of hospital sewage automatic gear 86202796, improving one's methods of some original conventional hospital sewage disposal systems disclosed among hospital and the service facility waste disposal plant 98228652.X, make equipment layout compacter, or make that to add conventional cholorination agent more convenient, level of automation is higher, and more than relevant patent does not have some principle matters (as not have the consideration pathogenic bacteria secondary pollution problem that air diffuser may cause in treating processes or some problems of cholorination) of existing in the radical change Hospital Sewage Treatment.Above simultaneously existing patent does not relate to membrane bioreactor and the Ultraviolet Disinfection of utilizing fully-closed and handles hospital sewage.
Summary of the invention
The purpose of this utility model provides has sterilization and disinfection, prevent a kind of fully-closed hospital sewage treating apparatus of not having diffusion of proliferation of germs, constitute by membrane bioreactor and uv steriliser, it is characterized in that: described hospital sewage treating apparatus is all-sealed structure, airtight grid 1, equalizing tank 2, the membrane bioreactor 9 of intake pump 3 and fully-closed is connected in series, membrane module 5 is immersed in the membrane bioreactor 9, gas blower 8 is connected the inlet mouth of membrane bioreactor 9, aeration tube 10 places the below of membrane module 5, and suction pump 6 is connected on the water outlet position of membrane module 5; The exhaust line 4 of system's each several part and connect the back be connected with a uv steriliser 7, another uv steriliser 7 is connected the water outlet of suction pump 6.
The beneficial effects of the utility model are: 1. total system adopts airtightly, and all gas of membrane bioreactor and equalizing tank and grid discharging is collected by pipeline and entered independent uv steriliser gas is carried out disinfection, prevent germ by gas to external diffusion.All reach or be better than country by the every index of the water outlet after the system handles at the emission standard GBJ48-83 of hospital sewage.2. the membrane bioreactor sludge yield is very little, does not have mud discharging substantially, greatly reduces the probability that pathogenic bacteria spreads by the mud discharging diffusion.3. suspended substance is given full play to the efficient effect of uv sterilisation to the interference of uv sterilisation in the elimination waste water.
Description of drawings
Fig. 1 is a fully-closed hospital sewage treating apparatus structural representation.
Embodiment
Figure 1 shows that the fully-closed hospital sewage treating apparatus structural representation that does not have diffusion.This hospital sewage treating apparatus adopts all-sealed structure.Airtight grid 1, airtight equalizing tank 2, intake pump 3 and airtight membrane bioreactor 9 are connected in series, and gas blower 8 is connected the inlet mouth of airtight membrane bioreactor 9, and suction pump 6 links to each other with the water outlet of membrane module 5.The gas exhaust duct 4 of this treatment unit each several part and connect the back be connected with a uv steriliser 7, another uv steriliser 7 is connected the water outlet of suction pump 6.
The suspended solid retaining was in grid 1 when hospital sewage passed through airtight grid 1, sewage enters equalizing tank 2, enter in the airtight membrane bioreactor 9 by wet-pit 3 pressurizations, the oxygen of aerobic reaction is provided by gas blower 8, in airtight membrane bioreactor 9, carry out biological respinse by aerobic microbiological and come pollutent in the degrading waste water, by be immersed in hollow-fibre membrane in the airtight membrane bioreactor 9 realize to virus and bacterium efficiently hold back effect, the excellence that reaches system's effluent index is discharged.Uv steriliser 7 sterilizations behind the gas exhaust duct 4 that this treatment unit each several part expellant gas is connected and connects, be connected 7 pairs of drainage water sterilizations of another uv steriliser of the water outlet of suction pump 6, uv steriliser 7 can all kill virus and the bacterium in system's water outlet and the discharge gas in the several seconds, guarantee non-secondary pollution, do not produce by product.
