A/O sewage treatment system
Our company based on the SBR technics ( sequencing batch reactor) developed a new kind matched equipment which can make up SBR many deficient; which can widely apply to all kind of sewage treatment plant. The package sewage treatment plant principle is a kind of biochemical treatment which combine activated sludge microbiological method and new biological membrane manner. In treatment process, large bacteria and bacteria membrane update, adopt biological carrier, improve the contact efficiency of micro- organism and pollutant matter in sewage; the whole treatment equipment produce anaerobic-anoxia- aerobic three kind of environment take turns function, improve purified water ability of different kind of microbial population, intensify organism removal and nitrogen and phosphorus removal function.
Traditional sewage treatment process can divide into biological membrane manner and activated sludge manner, biological membrane suitable to small water volume,steady water quality ,low concentration sewage water quality, better system commission. Steady back operation, better operability.
Combine our company past success practice, suggest sue biofilm manner treatment process, plan to adopt A/O biological contact oxygen process as main treatment manner. Such process is more mature, has certain history, widely used in textile system factories, such process main device has equalize tank,aeration tank and clarifier etc. equalize tank mainly use to equalize waste water quality and quantity in each pollutant source, prevent form impact to aeration tank, prevent bacteria die. Thus, it will be better of sewage stay long time in equalize tank, but it should consider construction expense.
So it design equalize tank according to enterprise production cycle and occupy area. Aeration tank main function is filling oxygen to sludge water mixture, ensure the activated sludge required oxygen volume in resolve organic matter, at the same time, make the activated sludge fully with sewage; the technical requirements to aeration tank is sludge loading is 0.3-.4kgBOD5/kg.MLSS.d, aeration time about 4-6h, sludge content is 3-4g/l usually.
Settling main use to make sludge and water separation, further degrade organic matter in settling, then discharge directly after sludge and water separation, part of sewage backflow into aeration tank, another parts of surplus sludge discharge.
The effluent first enter into grid tank, it equip with bar screen in the grid tank, which can remove bigger suspended matter, seston and ribbon in effluent, then flow into djusting tank, its main function is equalized water quality(COD,temperature,PH) and water volume, to avoid impact loading influence biological treatment, then the effluent enter flow into the integrated sewage treatment plant by lifting pump.
The sewage treatment plant main contain air flotation tank (dissolving tank), anxoic tank (biochemical tank), Oxidation tank (second biochemical tank), settling tank (second sedimentation tank), etc several parts. The main function of air flotation tank is remove flocculated suspended matter. In anoxia tank, which can improve sewage biodegradability, create conditions for further treatment, inside the anoxia tank, produce large number of anoxic bacteria, the intercept down organic matter broke chain or open loop, decompose into Simple low molecular organic which can be easy to absorb utilize by aerobic bacterium, effectively improve the subsequent aerobic phase of the treatment efficiency.
The sewage still contain some organic matter and higher content ammonia nitrogen. in order to make the organic matter further oxygenolysis, at the same time, carbonation tend to be completely, nitrification can proceeding smoothly, so set contact oxidation tank, its rely on autotrophic type bacteria finish treatment, they adopt Organic decomposition producing inorganic carbon source or carbon dioxide in air as nutritional sources, make the ammonia nitrogen in sewage convert into.
In oxidation tank equip with padding, the whole Biochemical process rely on many microbes attached on the padding.
Effluent water after separated will enter into disinfecting tank proceeding solid liquid separation, some effluent water from contact oxidation tank back flow into equalize tank proceeding internal Circulation, so achieve denitrification purpose, another parts will flow into secondary settling tank, make further solidliquid separation, the effluent water after separated will enter into cleaning water tank, then reuse in irrigation.
Main treatment unit
(1) Flocculant air flotation
Waste water is alkality, it contain sulfur compound, the common flocculant is PAC, flocculant aid is PAM, but too much PAC will influence follow up biological treatment, so such project will chose FM composite flocculant.
(2) Anoxic tank
In anoxic condition, organic in waste water finished the first section of anoxic reaction , which make the difficult biodegradable organic matter resolve into easy biodegradable small molecular organic matter, reduce CODcr, BOD5, SS, S2-, chroma, improve sewage biodegradability, create better condition for follow-up biological treatment.
(3) Biological treatment
Biological oxidation is the new biomembrane process, which produce bigger activated sludge content, to improve volume loading of contact oxidation tank, improve pollutant remove efficiency, at the same time, with the feature of small occupy, convenient maintenance, which has widely used in chemical industrial, food, pharmacy, printing etc industrial sewage treatment, with obvious effective.
