Description
Technical field
The present invention relates to field of waste water treatment, be specifically related to the conventional A/A/O(A(anaerobism in Treatment of Coking Effluent field)/A(anoxic)/O(is aerobic)) biochemical processing process, i.e. a kind of coking chemical waste water biochemical treatment and settling tank.
Background technology
Current coking chemical waste water complicated component, the organic pollutants such as heterogeneous ring compound, polycyclc aromatic compound, fatty compounds that wherein contain phenolic compound, nitrogenous, sulphur, oxygen are a kind of more typically containing the waste water difficult for biological degradation of aromatics and heterogeneous ring compound.At present, A(anaerobism)/A(anoxic)/0(is aerobic) technique is that treating coking wastewater biologically is applied more method, application in coking chemical waste water biological treatment engineering accounts for 25% at home, yet water outlet COD after most A/A/0 art breading is still more than 200mg/L.If the weak point in A/A/O technique is improved, improve the treatment effect of coking chemical waste water, will produce huge economic benefit and environmental benefit.
At present conventional A/A/O biochemical processing process floor plan basic structure is as Fig. 1, anaerobic pond 100 use anaerobic hydrolysis-acidifications change chemical structure and the biodegradability of hardly degraded organic substance in coking chemical waste water, thereby the aerobic biodegradability that has improved waste water, is conducive to follow-up aerobic biodegradation.
Anoxic pond 200(A pond), Aerobic Pond 300(O pond) generally build jointly, be the core monomer of coking waste water treatment process, the second pond 400 after A/O biochemical reaction tank is as solid-liquid separation tank, and aerobic sludge is separated with bio-chemical effluent.In coking chemical waste water, under the contained part COD aerobic condition in Aerobic Pond 300, decompose, the aerobic sludge producing in decomposition course is after second pond 400 precipitations, row except a small amount of, all the other enter sludge reflux well 700, by sludge reflux pump group 500, are back to Aerobic Pond 300 head ends; Meanwhile, NH3-N contained in coking chemical waste water changes into NO2-N by nitrococcus under aerobic condition, then by nitrifier by NO
2-be converted into NO
3-, after nitration treatment containing NO
3-mixed solution by mixed-liquor return pump group 600, be back to anoxic pond 200 head ends, take and enter organic substance contained in the coking chemical waste water of anoxic pond 200 as carbon source, under anoxia condition, by double oxygen bacterium, utilize NO
3-as electron acceptor(EA), carry out Anaerobic respiration, decompose the COD in sewage, realize NO simultaneously
3-denitrification.
In actual motion, the combination process of A/O biochemical reaction tank and follow-up second pond has following weak point:
1, aerobic sludge enters sludge reflux well 700 in second pond 400 after sedimentation, then returns Aerobic Pond 300 head ends through sludge reflux pump 500.Due to the anaerobic environment of second pond 400 and sludge reflux well 700, caused the activity of aerobic sludge not high on the one hand; On the other hand the aerobic sludge residence time short, biomass and bacterial classification in Aerobic Pond are few, sewage treatment capacity is low;
2, aerobic sludge is in sludge reflux pump group 500 pumping reflux courses, and flocculent structure suffers that water pump impeller destroys, and affects treatment effect, and most of sludge pump group lift is required over reality, and energy dissipation is serious, and return sludge ratio can only be controlled at lower scope;
3, in denitrification process, NO
3-refluxing has two kinds of forms: Aerobic Pond mixed solution directly refluxes (Fig. 1) or second pond supernatant liquor refluxes (Fig. 2).Aerobic Pond mixed solution directly refluxes and will make aerobic sludge enter the anoxic pond 200 of anaerobic environment, anoxic pond 200 treatment effects are brought to disadvantageous effect, simultaneously, anaerobic environment in anoxic pond 200 also affects the activity of aerobic sludge, and the backflow of second pond supernatant liquor will make second pond 400 treatment capacities greatly increase, second pond 400 volumes are strengthened at double, increase investment and take up an area.No matter use which kind of reflux type, the lift of reflux pump group 500 and reflux pump group 600 all substantially exceeds actual required, considers the energy consumption of reflux pump group, so nitrification liquid reflux ratio is controlled at below 4～5 times mostly, cannot reach higher total nitrogen decreasing ratio.
4, coking chemical waste water variation water quality is large, a little less than common A/0 technique impact resistance;
5, second pond 400 is circular radial-flow sedimentation tank, cannot build jointly with rectangle A/0 biochemical reaction tank, increases and takes up an area, and increases the complexity of pump group and pipeline.
In sum, in prior art, at least there is following problem: the water treatment micro-organism residence time is short, backflow aerobic sludge activity is influenced, biomass and the bacterial classification of water treatment micro-organism are few, weak effect is separated in low, above-mentioned each function treatment district of sewage treatment capacity mutually, the liquid in each function treatment district mixes mutually, influences each other.
Summary of the invention
The invention provides a kind of coking chemical waste water biochemical treatment and settling tank, short to solve the water treatment micro-organism residence time, backflow aerobic sludge activity is influenced, and biomass and the bacterial classification of water treatment micro-organism are few, sewage treatment capacity is low, and the problem of weak effect is separated in above-mentioned each function treatment district mutually.
