Description
Technical field
The utility model relates to a kind of middle water treatment system, is water treatment system in a kind of membrane bioreactor and the apparatus for ultraviolet disinfection bonded, belongs to water treatment field.
Background technology
China is the country of a shortage of water resources, and the human settlements water resources quantity is about 2200m
3, be about 1/4th of world average level.And China's water resource waste is serious, and water resource utilization efficiency is lower.Because the Industry Structure Industry Structure is unreasonable, the high water volume industry development is concentrated simultaneously, and production management level is low, and the water of productive use waste is serious; Thought of people is had less understanding, and lacks sense of crisis, and consciousness of saving water is poor, and city domestic water, domestic water wasting phenomenon are general; Lack overall control, violate the ecological rule development, the exploitation of predation formula, the utilization of waste formula, the management of chaotic formula occur; The repeating utilization factor of water is low, and relevant law, system are unsound, all is the reason that China's water resources crisis occurs.
Middle water reuse is the important channel that solves the city water resource crisis, also is the basic outlet of coordinating city water resource and water surrounding, and life sewage treatment and reuse can reduce can bring certain economic benefits to us again to phreatic exploitation.Middle water is meant various drainings after treatment, reaches the water quality standard of regulation, the undrinkable water that can use mixedly in scopes such as life, municipal administration, environment.Because its water-quality guideline is lower than the water quality standard of Drinking Water, but be higher than the water quality standard of the sewage that allows discharging, be between the two, so be called " middle water ".
Membrane bioreactor (Membrance Bio-Reactor is called for short MBR) technology is a kind of high-efficiency sewage treatment process that biological treatment combines and forms with membrane separation technique.Replace the second pond and the conventional filtration unit of traditional contact oxidation technology with membrane separation technique, the efficient solid-liquid separation capability of film makes effluent quality outstanding, and suspended substance and turbidity approach zero.
Membrane Bio-reactor Technology is a kind of new sewage treatment process that combines and form with ultrafiltration or micro-filtration technology and traditional activated sludge process, the mud-water separation process replaces the gravity settling of traditional technology with membrane sepn, no matter the settling property of solid particulate how, all can finish the mud-water separation process, and can avoid the biology of traditional activated sludge process to run off and cause the problem of thrashing.Membrane bioreactor is owing to almost completely hold back microorganism, but sludge retention time endless, so microbe population and kind are all very abundant in the reactor, system can move under high sludge concentration and low sludge loading, therefore degradation of organic substances is thorough, removes the effective of ammonia nitrogen, and effluent index is better than national standard and highly stable, surplus sludge volume is few, the simple and saving occupation of land of technology.
The ultraviolet radiation for sterilizing and disinfecting principle be utilize the ultraviolet ray of suitable wavelength in can the destroy microorganisms body cell DNA (thymus nucleic acid) or the molecular structure of RNA (Yeast Nucleic Acid), cause the growth cell death and (or) the reproducibility necrocytosis, reach the effect of sterilization and disinfection.Through test, the effective wavelength range of ultra-violet sterilization can be divided into four different wave bands: UVA (400～315nm), UVB (315～280nm), UVC (280～200nm) and vacuum ultraviolet ray (200～100nm).What can see through wherein that ozone layer and cloud layer arrive earth surface has only UVA and UVB part.With regard to sterilization speed, UVC is within the microorganism absorption peak scope, can within 1s, kill virus and bacterium by the dna structure by destroy microorganisms, and UVA and UVB are owing to be in outside the microorganism absorption peak scope, sterilization speed is very slow, often need a few hours just can play germicidal action, in the time, in fact this part belongs to invalid ultraviolet portion at the several seconds of actual engineering hydraulic retention (irradiation).Therefore, said ultraviolet disinfection in fact just is meant the UVC sterilization in the water supply and sewage work.The ultraviolet disinfection technology is based on the basis of modern anti-epidemiology, medical science and photodynamics, utilize high-level efficiency, high strength and long-life UVC wave band ultraviolet lighting water jets of particular design, various bacteriums, virus, parasite, algae and other pathogenic agent in the water are directly killed, reach the disinfectant purpose.
The middle water technology that adopts membrane bioreactor and ultraviolet radiation for sterilizing and disinfecting to combine combines advantage separately, and it is easier that equipment is installed, and treatment effect is stable, and working cost and first input expense are lower, have very strong practicality.
The utility model content
The utility model is according to the problem of above existence, adopt the knockdown middle water treatment device of membrane bioreactor and ultraviolet radiation for sterilizing and disinfecting, provide a kind of both efficient, but have the middle water technology of good sterilization effect and the cheap wide popularization and application of cost cost again.
Technical solutions of the utility model are made up of grid maker, equalizing tank, diving lift pump, hair collector, membrane module, Aeration fan, vacuum primingpump, apparatus for ultraviolet disinfection, middle pond, cleaning pond.
Sewage treatment process: sewage enters former water equalizing tank by drainage pipeline.Former water equalizing tank ingress is provided with grid maker, be used for tackling water greater than 3 millimeters particulate matter; Be provided with submersible pump in the former water equalizing tank, with sewage transport in reactor.The hair collector is set on pipeline, is used for tackling the hair of water; After sewage enters reaction tank, under the effect of aeration, water is formed in membrane bioreactor to circulate up and down, simultaneously under the filteration of the suction of vacuum primingpump and hollow-fibre membrane, make water see through hollow-fibre membrane, continue degraded in the bio-reactor, finish and large particulate matter is trapped in until degraded; For preventing the obstruction of hollow-fibre membrane surface, under the effect of aeration, the film silk is shaken fully, under the effect of mass force, the big material that floats over film silk surface is got rid of in the reactor, continue degraded; The water that comes out through vacuum primingpump directly enters middle pond, reuse in waterworks is transported to buildings again.On the pipeline between vacuum primingpump and the middle pond, ultraviolet sterilization apparatus is set, guarantees to handle back hygienic quality index and can satisfy reuse standard.
Bottom, described membrane biological reaction pond is provided with distribution device and blowdown apparatus, and the membrane bioreactor bottom air inlet connects gas blower.
The processing mode of membrane bioreactor combined uv, combine both advantages, effluent quality by membrane bioreactor is better, especially suspension content is lower, thereby make the ultraviolet penetration coefficient height of water, exposure intensity and the scope of UV-light in water is bigger, for follow-up disinfection by ultraviolet light has been carried out sufficient preparation.Simultaneously, apparatus for ultraviolet disinfection can become the sterilizing unit of enclosed ultraviolet radiation for sterilizing and disinfecting or open tunnel type according to water quality, water yield condition setting.
