Abstract
A sewage treating system for public lavatory is composed of three-stage septic tank, efficient membrane bioreaction for degradating pollutants and intercepting suspended solid, gas-liquid mixing unit, and efficient broad-spectrum ozone disinfecting unit.
Description
Technical field
The invention belongs to the sewage disposal technology scope, particularly have sterilization and disinfection, prevent proliferation of germs, non-pollutant discharge, the lavatory is with the reusable high-efficiency environment friendly of water cycle Public toilets Sewage treatment systems.
Background technology
It is the environmental protection difficult problem very ancient and technical difficulty is very big that sanitary wastewater is handled.Fast development along with China's economy, sanitary sewages such as lavatory increase day by day to the pressure of original municipal wastewater outfall pipeline, the discharge capacity of the underground sewage network in the most cities of China seriously descends in addition, and serious area has dropped to below 20% of initial ejection ability.If put into the melting pot original urban sewage discharge system, be a very huge engineering to local municipal administration.Except that the huge factor of engineering cost, to involving of other urban operating mechanism also be inconceivable.More feasible solution probably has two aspects:
On the one hand, can adopt the inner dredging method (mechanical type and biological process) of at present popular in the world non-unlatching pipeline; On the other hand, can carry out reuse to local sewage discharge zone and administer, accomplish few discharging even zero release, as far as possible to reduce pressure to municipal drainage.
To existing patent documentation inquiry, Decontamination plant for the toilet 85104520, fully enclosed multifunctional water closet 92105222.7, a kind of with treating excrement and urine with compound microbes method and install 01102944.7, biological self cleaning toilet system 00118350.8, the processing method 01129167.2 that the lavatory fecaluria is handled, digital intelligent control system of microbial environment protecting closet 02133579.6, a kind of water-saving ecological toilet 03117722.0 is exempted from bath/little ecological toilet 01225159.3, anhydrous washing-free toilet 01233260.7 discloses the rational method of some original sanitary wastewater treatment systems in 01268092.3 grade of a kind of circulating water to flush lavatory.But be weak aspect the water quality of reuse water, and processing, the sterilization of dirty gas is difficult to thoroughly, operational path is also advanced inadequately, does not reach environmental protection, the water-saving function of real meaning.With existing municipal drainage supporting, be connected very big problem also arranged.
Summary of the invention
The purpose of this invention is to provide a whole set of sterilization, sterilize, prevent dirty gaseous diffusion, the high-efficiency environment friendly Public toilets Sewage treatment systems of no sewage, emissions and water saving.
The object of the present invention is achieved like this: a kind of Public toilets Sewage treatment systems, the membrane bioreactor and the high-efficiency broad spectrum ozonization equipment that mainly comprise the high-performance bio bacterial classification constitute, this Public toilets Sewage treatment systems adopts the relative close type structure, be used for preventing that at sewage treatment process all contaminations that discharge in the lavatory and unpleasant odor gas are to the pollution of system's outside atmosphere.Described fully sealed high-efficiency membrane bioreactor and airtight grille well and three grades of septic tanks are connected in series.The ozone tail gas collection device of gas-liquid mixed equipment by pipeline be connected from three grades of septic tanks, the vapor pipe that contains the high performance membrane bio-reactor of dominant microflora and enter independent ozonateur, dirty gas is mixed with ozone tail gas and make it to be sterilized, taste removal.In the high performance membrane bio-reactor, by the microbial process of dominant microflora, all contaminations in the degradation of sewage, and suspended solid efficiently is trapped in the membrane bioreactor.Water outlet in gas-liquid mixed equipment with high-efficiency broad spectrum sterilizing agent ozone thorough mixing, further reduce the level of water pollutant.
Owing to having above-mentioned structure, the system final outflow water of making to reach Ministry of Construction's " miscellaneous domestic water quality standard " and being recycled repeated use, the environmental protection of system, water saving characteristic are achieved.Native system is equally applicable to Hospital Sewage Treatment and marine domestic sewage process field.

Figure 1 shows that Public toilets Sewage treatment systems synoptic diagram.
Among the figure, 1-one-level septic tank; 2-grid; 3-two, three grades of septic tanks; 4-wet-pit; 5-high performance membrane bio-reactor; 6-suction pump; 7-independent ozonateur; 8-gas blower; 9-ozonizer; 10-ozone tail gas collector; 11-clean water basin; 12-urinal.
Embodiment
Referring to Fig. 1, Public toilets of the present invention Sewage treatment systems adopts all-sealed structure, is used to prevent at sewage treatment process.Sanitary wastewater through septic tank 1 precipitation anaerobic digestion, by precipitation step by step, the purification of airtight grid 2 and two, three grades of septic tanks 3, is pumped in the airtight membrane bioreactor 5 by wet-pit 4 earlier again.Gas blower 8 is connected the inlet mouth of membrane bioreactor 5, and aeration tube places the below of membrane module, and suction pump 6 is connected on the water outlet position of membrane module; The exhaust line of system's each several part also connects the back and is connected with independent ozonateur 7, dirty gas wherein, via be sterilized from the mixing of the residual ozone in the ozone tail gas collector 10, taste removal.The employing of film keeps off suspended solid in membrane bioreactor 5, provide dominant microflora to carry out the required dissolved oxygen of biological respinse by gas blower 8, with the pollutent in the degradation of sewage, realize efficiently holding back to virus and bacterium by the hollow-fibre membrane that is immersed in the reactor.Water outlet in clean water basin 11 with from the ozone thorough mixing that produces in the ozonizer 9 and be sterilized, decolour, system's water outlet reaches Ministry of Construction's " miscellaneous domestic water quality standard ", be used for flushing toilet bowl 12 or, reach the purpose that recycles as the water of purposes such as greening.
