Description
Technical field
The multipoint water feeding Zeolite-bio combined adsorption regenerative sewage treating process relates to municipal effluent, sanitary sewage and the industrial organic waste water pollutant removal and the processing of (comprising organism, ammonia nitrogen, phosphorus).
Background technology
Main denitride technology comprises biological process and physico-chemical processes at present.Biological process is that the nitrification and denitrification effect by specified microorganisms removes the itrogenous organic substance in the sewage.This method energy consumption is little, and running cost is low, and present most sewage works all adopt biological process to reach denitrification effect.But biological process exists hydraulic detention time long, and floor space and capital cost are big, and treatment effect is subject to shortcomings such as weather effect, effluent quality instability.
Physico-chemical processes comprises break point chlorination method, ion exchange method and air stripping method etc., its advantage is that high-level efficiency at short notice removes the itrogenous organic substance in the sewage, but running cost and energy consumption are higher, and processes such as for example chlorine residue removes its subsequent technique, ion-exchanger conditioning are more loaded down with trivial details, feasibility and economy are inferior to biological process, can not generally be promoted.
And be to select absorption ammonia nitrogen, absorption dissolved organic matter, flocculation to remove suspension organism and microorganism in zeolite the bio-regeneration of zeolite powder, microorganism are combined the flocculation absorption of suspension pollutent etc. at the Zeolite-bio combined adsorption regenerative treatment process of above-mentioned shortcoming exploitation, shortened hydraulic detention time greatly, and advantage such as it is effective to have a water outlet, and stable and floor space is little.But also there is following some deficiency in this technology: (1) requires under the low situation at the water outlet ammonia nitrogen concentration, and adsorption tank zeolite concentration requirement is higher, and the amount of zeolite that need add is bigger; (2) regenerated reactor is provided with denitrification process, and the denitrification section may be because the carbon source deficiency influences denitrification effect; (3) this technology does not have the removal of consideration to phosphorus; Therefore, this technology is still waiting further to optimize.
Existing sewage dephosphorization technology has biological phosphate-eliminating method and chemical dephosphorization method.Biological phosphate-eliminating is to release phosphorus, aerobic section excess according to storage phosphorus microorganism in the anaerobism section to inhale the removal that the principle of phosphorus contains phosphor contaminant in realizing water by spoil disposal, though this method working cost is low, energy consumption is little, but also exist treatment effect instability, the difficult control of operational condition, excess sludge still to need shortcomings such as dephosphorization, and difficulty is carried out synchronously with biological denitrificaion.Chemical dephosphorization can remedy the deficiency of biological phosphate-eliminating, but because its medicine dosage is big, reasons such as running cost height are difficult to obtain promotion and application.
Summary of the invention
In order to overcome above-mentioned shortcoming, effectively reduce the load of adsorption stage in the sewage treatment process, and realize that in RS Regenerator Section the zeolite powder regenerated can remove pollutents such as total nitrogen, organonitrogen, ammonia nitrogen and COD simultaneously, and make whole technology have phosphor-removing effect, the inventor combines Zeolite-bio combined adsorption regenerative treatment process, A/O (denitrification/nitrated) denitrification process and chemical dephosphorization method by having researched and proposed, and forms the multipoint water feeding Zeolite-bio combined adsorption regenerative sewage treating process of disposing of sewage thus.
" multipoint water feeding Zeolite-bio combined adsorption regenerative sewage treating process " that the present invention proposes is directly to be added to zeolite powder in the adsorption tank, utilize physics, chemistry, the biological synergetic effect of zeolite powder mud, suspension and solvability organic pollutant in the absorption sewage are simultaneously by the ammonia nitrogen in the zeolite powder absorption exchange waste water.Chemical dephosphorization adopts coagulant dosage to the waste water that enters adsorption tank or from the effusive muddy water mixed solution that contains zeolite powder of adsorption tank or directly be added to and realize quick synchronized mixes reaction dephosphorization in the adsorption tank, make after the effusive muddy water mixed solution that contains zeolite powder of adsorption tank enters second pond and concentrate by solid-liquid separation, the water and the excess sludge of treated mistake are discharged, and being back to, part zeolite powder mud adopt the RS Regenerator Section of A/O (denitrification/nitrated) denitrification process to carry out bio-regeneration, in order to reach good denitrification effect, simultaneously a part of waste water is introduced directly into the A section, provide enough carbon sources by multipoint water feeding for denitrification, reduce the load of adsorption stage, improve effluent quality.Highly active zeolite powder mud after regeneration is back to the operation of putting into adsorption tank in the adsorption tank again again.
The multipoint water feeding Zeolite-bio combined adsorption regenerative sewage treating process had both kept the advantage of Zeolite-bio combined adsorption regenerative treatment process, the ammonia nitrogen and the total nitrogen concentration of water outlet have further been reduced again on this basis, when making this Process for Treating Municipal, stable effluent quality reaches one-level B standard in the country " urban wastewater treatment firm pollutant emission standard GB18918-2002 ", at this moment, the total hrt of biological treatment is no more than 4 hours, the excess sludge concentration of discharging reaches 3%, can reduce sewage work's investment and working cost significantly.
Characteristics of the present invention are:
(1) added zeolite powder in the adsorption tank, not only ammonia nitrogen has been had the absorption exchange interaction, and organism is also had the good adsorption performance, can organically combine with microbial process again simultaneously, so effluent quality is good, COD and ammonia nitrogen concentration are all lower.
(2) because the settleability of zeolite powder mud is good, make sludge back flow quantity few, the regenerated reactor volume obviously dwindles, and bio-regeneration efficient improves greatly, thereby has saved initial cost.
(3) RS Regenerator Section adopts denitrification/nitrated (A/O) technology, zeolite powder is well regenerated and total nitrogen in the sewage can be removed, sewage both provided sufficient carbon source for denitrification and directly introduce partly in the denitrification section, improved regeneration effect, can reduce the load of adsorption tank again, effluent quality is improved and improve, the water outlet total nitrogen concentration is also lower.
(4) sludge concentration is greater than the sludge concentration of conventional biological treatment in the reaction tank of technology of the present invention, and is stronger to the adsorption-flocculation performance that contains phosphor contaminant in the waste water, so the required coagulating agent of dephosphorization is adding less;
(5) because zeolite powder is cheap, and be used for the zeolite powder of sewage disposal, major part can be used repeatedly by solid-liquid separation, need to mend the zeolite powder that adds after stable seldom, so the actual motion expense is low.
(6) technology of the present invention can be kept the steady running in age of long mud, the low and inanimate matter content height of sludge yield, and its treatment and disposal is easier to be more more convenient than conventional excess sludge, and expense is also lower.
The present invention not only can be applied to the processing of municipal effluent, sanitary sewage, also be applicable to can biochemical industrial organic waste water processing, for sanitary wastewater, municipal effluent and can biochemical industrial organic waste water in organism, ammonia nitrogen, total nitrogen and phosphorus all can handle qualified discharge, have tangible economic benefit, environmental benefit and social benefit.
