Technical field
The present invention relates to Sewage treatment systems, be specifically related to a kind of oxygenation filtering system being applicable to advanced treatment of wastewater.
Background technology
Along with China's urbanization and industrialized progress faster, urban wastewater treatment firm is collected and has been processed most city domestic sewage, and the water displacement growth of this part is relatively swifter and more violent, and this poses a big pressure to the environment of a given area.If still according to the emission request design operation urban wastewater treatment firm of " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level B standard, nitrogen wherein, phosphorus etc. accumulate over a long period in water body, will cause eutrophication to water body.
Realizing mainly through single or combination physics, chemistry, physical chemistry and biological method of advanced treatment of wastewater.
At present, the method for the treatment of of domestic sewage advanced is generally coagulation, precipitation, filtration, sterilization, if having higher requirement can select the methods such as charcoal absorption, ion-exchange, reverse osmosis to water quality.The water outlet of filter tank to second-level settling pond processes at a slow speed, and it has good removal effect to turbidity, COD, colourity; Flocculation sediment-V-type filter tank can the sanitary sewage of advanced treatment low-carbon-source.Meanwhile, there are some researches show that the advanced treatment that also can realize sewage is combined in micro-filtration, nanofiltration, ultrafiltration, reverse osmosis.The advanced treatment of sanitary sewage also can use biological method and membrane processing method to realize, such as MBR, BAF, MBBR, biological diafiltration, artificial swamp etc.But these method Shortcomings, are mainly manifested in:
1. Chemical deep facture needs to add chemical agent, and chemical agent not only increases running cost, also may impact natural water;
2. the film of film depth logos needs to change, and replacement cost is higher, and meanwhile, the scavenging solution of film easily causes secondary pollution;
3. the floor space of filter tank and artificial swamp is comparatively large at a slow speed, is not suitable for the advanced treatment of wastewater in the area of some land used anxieties;
4.BAF etc. need some to shut down the processing mode of back flushing, easily impact operating performance, and have certain technical requirements to staff.
Summary of the invention
The object of this invention is to provide a kind of floor space little, easy and simple to handle, the good and oxygenation filtering system being applicable to treatment of domestic sewage advanced of stable effluent quality for the treatment of effect.
The present invention is achieved in that the oxygenation filtering system being applicable to advanced treatment of wastewater comprises advanced treatment of wastewater pond, is provided with leads abrasive cone in the bottom in advanced treatment of wastewater pond; Lead above abrasive cone and be provided with water distributor, water distributor connects the thrust-augmenting nozzle at center, advanced treatment of wastewater pond; The thrust-augmenting nozzle the other end is connected with water inlet pipe; Water inlet pipe stretches out advanced treatment of wastewater pond, and water inlet pipe is provided with oxygen replenishing equipment, intake pump and vacuum breaker; Center, advanced treatment of wastewater pond is provided with sand developing tube; Sand developing tube successively through leading abrasive cone, thrust-augmenting nozzle center from bottom toward top, is provided with bottom sand developing tube and carries sand valve, top is provided with sand-washing device; Carry the sand valve the other end and connect blast main, the blast main the other end stretches out advanced treatment of wastewater pond and connects air lift; Sand-washing device spirally around sand extraction tube top, and is provided with washed-out sand rising pipe; Top, advanced treatment of wastewater pond is provided with effluent trough; Effluent trough top is provided with effluent weir, bottom is provided with rising pipe; Filtering layer is provided with in advanced treatment of wastewater pond; Advanced treatment of wastewater is provided with blow-down pipe bottom pond.
Described oxygen replenishing equipment is ejector.
Described water distributor is perforated pipe, by center to periphery by-pass line radially water distribution uniformity.
The filtrate of described filtering layer is porous sintered ceramic particle, and particle diameter is 0.8 ~ 3mm, and the ratio of filtering layer height and advanced treatment of wastewater pond height is 0.6 ~ 0.9:1.
Described effluent trough is surrounded on inwall top, advanced treatment of wastewater pond, is provided with effluent weir on effluent trough top.
Filtrate bottom filtering layer is under the effect of air lift, enter sand developing tube by carrying sand valve and be thus lifted in sand-washing device, filtrate falls filtering layer upper surface after being cleaned by sand-washing device, the sewage that cleaning after stain substrate concentration is higher arrives washed-out sand rising pipe through sand-washing device water outlet, and is back to biological processing unit above and processes.
The oxygenation filtering system being applicable to advanced treatment of wastewater can select operation cleaning and resting period property continuously to clean two kinds of patterns according to the concentration of dirty water pollutant and biomembranous thickness.
Compared with prior art, the feature of system of the present invention is:
1. floor space is little, and the present invention is cylindricality tank body, and transporting something containerized row and cleaning one, need not separately establish recoil wash pool, the floor space of facility can be reduced.
2. sewage before entering advanced treatment of wastewater pond through oxygen replenishing equipment oxygenation, rich oxygen containing sewage forms aerobic layer bottom filtering layer, promote microbial growth, filtering layer top then can form anoxic pond, and the removal for COD, ammonia nitrogen, TN provides good condition.
3. the space of filtrate porous sintered ceramic particle prosperity can be biofilm development, attachment provides good place, improves the biological activity of system; The absorption of porous sintered ceramic particle and crown_interception can also have higher processing rate to the SS in sewage; Meanwhile, the high-strength characteristic of porous sintered ceramic particle, avoids filtrate to be destroyed in cleaning process.
4. cleaning model is flexible, operation cleaning and resting period property continuously can be selected to clean two kinds of patterns according to the concentration of dirty water pollutant and biomembranous thickness.
