In the present embodiment, above-mentioned bio-contact oxidation system is provided with biological contact oxidation equipment.
In the present embodiment, above-mentioned biological contact oxidation equipment is polyfunctional reactant unit, and polyfunctional reactant unit comprises removes BOD, nitration reaction and absorption phosphorus reaction unit.
In the present embodiment, above-mentioned MBR film reaction system is provided with membrane reactor.
In the present embodiment, above-mentioned bio-contact oxidation system and MBR film reaction system are provided with Aeration fan.
In the present embodiment, the pipeline that above-mentioned vacuum primingpump draws water to clean water basin is provided with sterilisation system.The pipeline that vacuum primingpump draws water to clean water basin is provided with sterilisation system.
Sanitary sewage enters equalizing tank regulating pondage, balanced water quality, more successively through anaerobic pond and anoxic pond, utilizes that anerobe makes organism be hydrolyzed, acidifying in anaerobic pond, removes dirty Organic substance in water and discharges phosphorus; Anoxic pond carries out denitrification denitrogenation, rise to bio-contact oxidation system by lift pump afterwards and carry out aeration, the intrasystem biological contact oxidation equipment of bio-contact oxidation is polyfunctional reactant unit, removes BOD, nitration reaction and absorption phosphorus etc. and occurs all herein.Reuse standard is reached for making effluent quality, water after biological contact oxidization treatment enters MBR film reaction system again, and the intrasystem membrane reactor of MBR film reaction, because of its effective crown_interception, can retain the microorganism that life cycle is longer, further denitrogenation dephosphorizing, realizes the deep purifying of sewage.Water after purification is sterilized through sterilisation system, and is evacuated to clean water basin by vacuum primingpump, and the water in clean water basin is evacuated to by reuse pump and uses water place.Sanitary sewage can all afforest as this district, sweep ground, landscape water moisturizing etc. after treatment.
Living quarters sanitary sewage every day total amount is about 100m3, every day, system operation time was 20h, the Project design water yield is 5m3/h, the utility model adopts bio-contact oxidation+film process MBR technique+sterilization, after process, water outlet reaches zero-emission sea, all afforest as this district, sweep ground, landscape water moisturizings etc., effluent quality reaches " urban sewage reutilization urban reclaimed water water quality " (GB/T18920-2002) and " urban sewage reutilization water for scenic environment use water quality " (GB/T18921-2002).
Above-mentioned bio-contact oxidation is a kind of biological sewage treatment method derived from from biomembrance process, namely in biological contact oxidation pond, load the filler of some amount, utilizing dwells is attached to the oxygen of microbial film on filler and ample supply, pass through biological oxidation, oxidation operation in waste water is decomposed, reaches purification object.
Biological contact oxidation process is the microbial film be attached on carrier (being commonly called as filler) is main, a kind of High-efficient Water treatment process of purification of organic waste water.There is the biomembrance process of activated sludge process feature, have the advantage of activated sludge process and biomembrance process concurrently.Can under biochemical condition, no matter be applied to the process of trade effluent or aquaculture wastewater, sanitary sewage, all achieve good economic benefit.This technique is because having the features such as energy-efficient, floor space is little, anti impulsion load, operational management are convenient.
Biological treatment is through the link after materializing strategy, also be the important step in whole circulation process, here the objectionable impurities such as ammonia/nitrogen, nitrous acid, nitrate, thiocyanogen all will be removed, and will play a key effect to the further process of water quality in later flow process.
Membrane Bio-reactor Technology is a kind of high-efficiency sewage treatment process combined with membrane separation technique of carrying out a biological disposal upon.Due to the application of film, substantially increase the water quality standard of process water outlet, comparatively meet the development trend that Treated sewage reusing purposes requires.In view of this trend, in nearly 2 years of membrane Bio-reactor Technology water in small-scale sewage process and urban architecture (bath wastewater is former water), application is more and more, has greatly the trend of the Biological Contact Oxidation Process replacing dominate nearly ten years.
Membrane bioreactor (MembranceBioreacter, MBR) is the biochemical reaction system be integrated in one by the biological degradation of membrane separation technique and bio-reactor.Membrane separation technique is physical processing techniques conventional in sewage treatment area, and its mechanism mainly sieve effect, according to different film surface apertures sizes, can be divided into filtration, micro-filtration (MF), ultrafiltration (UF) and nanofiltration (NF) etc.What usually adopt in membrane bioreactor is micro-filtration and ultra-filtration membrane, its separating mechanism mainly sieve effect, and because of the difference of membrane structure, crown_interception can be divided into mechanical retention substantially, absorption retains and bridging action etc.This technique has the features such as processing power is strong, solid-liquid separation efficiency is high, effluent quality is good, occupation of land space is little, operational management is simple.
At present, MBR Technology process sanitary sewage and trade effluent highlight effect.Membrane module is the core of MBR, what adopt is immersed flat plate membrane biologic reaction equipment, the unique aeration tube of plate film assembly configuration through optimizing, aeration is enable to act on flat sheet membrane surface equably, farthest increase oxygen transfer efficiency, reduce the impact of concentration difference polarization, except having compact construction, aesthetic in appearance, reliable and stable, outside the advantages such as convenient operating maintenance, also there is better antifouling property, good mechanical stability, without fracture of wire phenomenon, purging method is more convenient, cleaning interval is longer, life-span is long, working cost is low, the advantages such as film Renewal process is simple.
