Abstract
The utility model discloses a hospital sewage treatment system based on an MBR (Membrane Biological Reactor), relates to a sewage treatment system, and aims to solve the problem that in the prior art, the hospital sewage treatment effect is poor, and further pollution or infection is easy to occur. The technical scheme is that the hospital sewage treatment system comprises a lift pump used for lifting sewage to a pre-filter; the back end of the pre-filter is connected with a membrane treatment unit; the back end of the membrane treatment unit is connected with a sludge drawing pump used for drawing sludge; the membrane treatment unit comprises an anoxic tank for receiving sewage sent by the pre-filter; the back end of the anoxic tank is connected with an aerobic tank; the back end of the aerobic tank is connected with a membrane treatment tank; a membrane treatment component is positioned in the membrane treatment tank; aeration devices are arranged at the bottoms of the aerobic tank and the membrane treatment tank; and the back end of the membrane treatment tank is connected with a backwashing unit and a disinfecting-and-cleaning unit which are used for conducting anti-pollution treatment on the membrane treatment component. The hospital sewage treatment system is mainly applied to sewage treatment in hospitals or similar environments.
Description
Technical field
The utility model relates to a kind of Sewage treatment systems, particularly relates to a kind of hospital sewage disposal system based on MBR.
Technical background
Though hospital sewage only accounts for the sub-fraction of China's total amount of sewage discharge; but hospital sewage source and complicated component; contain a large amount of pathogenetic bacterias, virus and chemical agent; have features such as space-pollution, acute infection and latent infection; effectively processing can not become the important channel that an eqpidemic disease spreads, thereby serious environment pollution increases the weight of China's water crisis.
Traditional biochemical processing process device processing rank is generally lower, and the treat effluent concentration of suspension is higher, and sterilisation effect is poor.Remaining malignant bacteria, virus and parasitic ovum enter receiving water body with water outlet, cause the pollution to water body environment, edatope and near farm crop, and surrounding population is also formed direct or indirect harm.Because the Hospital Sewage Treatment facility is relatively backward, equipment operation maintenance and management workload are big, and level of automation is low.In system's operational process, managerial personnel directly contact sewage and mud, easily cause infection.Described herein MBR is meant: Membrane Bio-Reactor, membrane bioreactor.
The utility model content
The purpose of this utility model is that solution prior art institute of traditional Chinese medicine wastewater treatment efficiency is poor, forms easily and further pollutes or the problem of infection, and a kind of hospital sewage disposal system based on MBR is provided, the native system full automatic control, and treatment effect is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hospital sewage disposal system based on MBR, comprise the lift pump that is used for sewage is risen to prefilter, the rear end of prefilter is connected with the film processing unit, film processing unit rear end is connected with the mud extraction pump that is used to extract mud, wherein the film processing unit comprises that acceptance sends into the anoxic pond of sewage from prefilter, the anoxic pond rear end is connected with Aerobic Pond, the Aerobic Pond rear end is connected with the film treating pond, and the film processing components is positioned at the film treating pond.
Bottom at described Aerobic Pond and film treating pond all is provided with aerating apparatus.
Be connected with backwash unit and the sterilization cleaning unit that is used for the film processing components is carried out anti-pollution processing in film treating pond rear end.
From above-mentioned said structure feature of the present utility model as can be seen, its advantage is: can full automatic control move, after modular design, upgrading is very easy to, stable water outlet and effluent quality are good, because the film processing unit effectively tackles bacterium, disinfect convenient and disinfectant consumption few, save great amount of cost, and treatment effect is good, remaining after treatment sludge concentration height, strong shock resistance the utlity model has good marketing using value.
Description of drawings
The utility model will illustrate by way of compared with accompanying drawings and combined with example:
Fig. 1 is a structural representation of the present utility model
Wherein Reference numeral 1 is that prefilter 2 is that lift pump 3 is film processing units
The 4th, mud extraction pump 5 is that anoxic pond 6 is Aerobic Ponds
The 7th, film treating pond 8 is film processing components
The 9th, aerating apparatus 10 is that backwash unit 11 is sterilization cleaning units
Embodiment
The utility model is described further by embodiment below in conjunction with accompanying drawing:
Preferred embodiment
A kind of hospital sewage disposal system as shown in Figure 1 based on MBR, comprise the lift pump 2 that is used for sewage is risen to prefilter 1, the rear end of prefilter 1 is connected with film processing unit 3, film processing unit 3 rear ends are connected with the mud extraction pump 4 that is used to extract mud, wherein film processing unit 3 comprises that acceptance sends into the anoxic pond 5 of sewage from prefilter 1, anoxic pond 5 rear ends are connected with Aerobic Pond 6, and Aerobic Pond 6 rear ends are connected with film treating pond 7, and film processing components 8 is positioned at film treating pond 7.
Bottom at described Aerobic Pond 6 and film treating pond 7 all is provided with aerating apparatus 9.
Be connected with backwash unit 10 and the sterilization cleaning unit 11 that is used for film processing components 8 is carried out anti-pollution processing in film treating pond 7 rear ends.
The function of various piece or effect can be described as in the utility model: prefilter mainly is to utilize block to hold back macrobead suspended substance in the sewage, to prevent that deposition is to the surface damage of membrane module in the process of aeration; Anoxic pond mainly is the small organic molecule that the macromolecule long-chain organism in the sewage is decomposed into easy biochemistry, carries out organic anti-nitration reaction simultaneously to finish denitrification functions; Be equipped with aerating apparatus at the bottom of the pond of Aerobic Pond and uninterruptedly carry out aeration, sewage carries out the organism biochemical degradation and carries out the biological nitration reaction simultaneously in this pond; In the film treating pond, by the efficient crown_interception of film processing components, whole bacterium and suspended substances all are trapped, and can effectively hold back nitrifier, and nitration reaction is carried out smoothly, effectively remove ammonia nitrogen; Simultaneously can hold back the larger molecular organics that is difficult to degrade, prolong its residence time in reactor, make it to be degraded to greatest extent; The utility model is provided with the mud extraction pump, regularly will remain a spot of mud and discharge; The utility model can also be provided with reflux pump, and the mixed solution after handling is carried out denitrification by being back to anoxic pond; Aerating apparatus in the film treating pond can carry out the air water vibration to film on the one hand and clean, and keeps the cleaning surfaces of film, in addition further biodegrade; Follow-up treating processes comprises backwash unit and sterilization cleaning unit, can place the pollution on film processing components surface, in addition since membrane reactor part to organism, bacteriophagees etc. have very high clearance, so the consumption of sterilizing agent is very little, greatly reduce the disinfectant consumption in traditional chlorine disinfectant technology, reduced the carcinogenic and teratogenesis by product of the use generation of chlorhexidine-containing disinfectant.
Disclosed all features in this specification sheets except mutually exclusive feature, all can make up by any way.
Disclosed arbitrary feature in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
