Abstract
The invention sets up a novel technique for treating sewage of an aeration biofilter having the function of reinforced deodorization. The technique combines sewage treatment and deodorization treatment, under the prerequisite of up-to-standard discharge, and adopts a composite filler to replace the ceramsite filler of the aeration biofilter; after domestication, the aeration biofilter can have thefunction of bio-deodorization while treating sewage. The technique is implemented by filling the composite filler which is composed of ceramsite, coarse granule active carbon and iron scrap with thevolume ratio being 1:0.2:0.15 into the aeration biofilter; adopting reek to be treated to replace air to be as the aeration gas source of the aeration biofilter; and after domestication, generating high efficient deodorizing bacteria groups such as desulfurated and deaminized bacteria and the like, so as to realize treating sewage and deodorizing stink gas simultaneously in the aeration biofilter.The invention does not change the equipment parameters of the original sewage treatment system and is favorable for upgrading and modifying civil sewage and industrial sewage plants.
Description
Affiliated technical field
The present invention has set up a kind of new technique for treating sewage of aeration biofilter with function of reinforced deodorization, will treat the aeration source of the gas of de-odorised foul smell as BAF, adopts this technology to carry out the biological deodorization of foul smell in normal processing sewage.Belong to environmental pollution improvement and prevention and control field.
Background technology
Along with improving constantly of wastewater treatment in China rate, in processes such as sewage disposal, sludge treatment, the odor pollution that a large amount of foul gass of generation cause is serious day by day.The gaseous constituent complexity of odorant pollutant mainly comprises: hydrogen sulfide, ammonia, amine etc.In the past, industrial sewage was handled or municipal wastewater is handled the qualified discharge of often only paying attention to sewage, and odorant pollutant is not effectively administered.People's Environmental awareness is progressively strengthened in recent years, and the odor pollution control problem in the sewage treatment process needs to be resolved hurrily.
The treatment process of foul gas mainly is divided into two big classes: (1) physico-chemical process: as direct burning method, catalyst oxidation method, soda acid ablution, absorption method, ion method etc.; (2) biological deodorizing method: bio-trickling filter method, soil deodorization method etc.At present, the biological deodorizing technology is applied extensively owing to the advantage of aspects such as running maintenance and enthusiasm.
The biological deodorizing method is to utilize autotrophic type and heterotroph microorganism under aerobic condition repugnant substance to be carried out oxygenolysis, and microorganism is decomposed into CO with the pollutent in the waste gas
2, H
2O and other inorganic salts, thus waste gas is purified.The mechanism of the soil deodorization method in the biological deodorizing is the water-soluble foul smell class in the foul gas, removed by the moisture absorption in the soil, but not the dissolubility foul smell then earlier by after the soil particle absorption again by microbiological degradation in the soil.The characteristics of soil deodorization method are that maintenance cost is low, but are unsuitable for rainfall, area that snowfall is big.The bio-trickling filter method is to utilize in the pond on the filler microorganism of apposition growth that odorant pollutant is decomposed, and the sewage of spray appropriate amount makes filler relative humidity remain on 80～95% above filler, and provides nutrition for microorganism.Filler requires adhering to of suitable microorganism and grows, and big specific surface area is arranged, and keeps higher microbial biomass, and is ageing-resistant etc.Filler commonly used has: bark, medium-soft plastics, fibering peat etc.
Summary of the invention
At present, Sewage treatment systems and the deodorizing treatment system in the Sewage Plant is separate system.The present invention seeks to by having set up a kind of new technique for treating sewage of aeration biofilter with function of reinforced deodorization Sewage treatment systems and deodorizing treatment system to be united two into one, relatively have following characteristics with conventional deodorization process: (1) has saved the floor space of conventional deodoration system; (2) reduced the investment of deodoration system; (3) reduced the workload of Sewage Plant running maintenance.Under the prerequisite that does not influence normal operation of sewage treatment facility and qualified discharge, make aerating biological filter sewage processing system have the function of biological deodorization simultaneously.
The mechanism of solution of the present invention is: (1) adopts compounded mix to substitute the ceramics filling of conventional BAF; (particle diameter is 1.0～1.5mm) to compounded mix, (particle diameter＞1.0mm) form with waste iron filing is adding in 1: 0.2: 0.15 according to volume ratio to the coarse particles gac by haydite.Wherein at the bottom of packing layer filling haydite, the coarse particles gac and the iron filings that recharge above the haydite and mix.Utilize the removal effect of the interior electrolytic action reinforcement of iron carbon to organism in the sewage and repugnant substance, the iron filings in iron carbon filler district are to the S in the sewage
2-Have stronger crown_interception (2) by cultivating domestication, make BAF sewage disposal deodorization device produce high-efficiency desulfurization deamination bacterium, make BAF H
2S, NH
3Deng having bigger metabolism and removal capacity.Foul smell is cut into small bubbles by aeration head during with filler and fully contacts with sewage, makes the gas-liquid mass transfer of foul gas composition more complete.Water-soluble H
2S, NH
3Deng contacting with microorganism on the filler with in the sewage, adsorbed by Institute of Micro-biology, the metabolism by microorganism obtains oxidation or degraded then.Wherein sulphur is that thing is oxidized into sulphur and sulfuric acid, NH
3Be degraded into nitrogen by nitrated-denitrification.
The technical solution adopted for the present invention to solve the technical problems is: at first compounded mix is loaded in the BAF; (particle diameter is 1.0～1.5mm) to compounded mix, (particle diameter＞1.0mm) form with waste iron filing is adding in 1: 0.2: 0.15 according to volume ratio to the coarse particles gac by haydite.Wherein at the bottom of packing layer filling haydite, the coarse particles gac and the iron filings that recharge above the haydite and mix.Then pending sewage is inserted the water inlet pipe of BAF.To treat the aeration source of the gas of de-odorised foul smell again, insert the inlet pipe of BAF by blower fan as BAF.Make pending sewage and foul gas pass through the ceramics filling district and the iron carbon filler district of BAF successively.On the one hand, microorganism utilizes the oxygen in the foul smell that the organism in the sewage is degraded, and carries out denitrogenation dephosphorizing, makes the effluent quality of BAF realize qualified discharge.On the other hand, after taming the deodorizing floras such as high-efficiency desulfurization deamination bacterium in the filler with the NH in the foul smell
3And H
2Foul smell compositions such as S are effectively removed by metabolism, and the foul gas decreasing ratio is reached more than 90%.
Beneficial effect of the present invention:
1. having set up a kind of new technique for treating sewage of aeration biofilter with function of reinforced deodorization unites two into one Sewage treatment systems and deodorizing treatment system, need not increase the floor space of original BAF, save the floor space and the investment of conventional odor removal.
2. reduced the running maintenance workload of conventional odor removal, the shortcoming of having avoided conventional deodorizing biological filter to stop up easily.
3. the present invention is suitable for the upgrading of the deodoration system of municipal wastewater processing and industrial sewage processing, remarkable in economical benefits.
4. the present invention does not change the processing parameter and the sewage disposal device parameter of original Sewage treatment systems.
