Background technology
Exhaust gas treatment technology of the prior art adopts following methods more:
Physical method is mainly to adopt charcoal absorption, and in active carbon filling and adsorption tower, when foul smell process adsorption tower, odorant is by charcoal absorption.Absorption method deodorising effect is good, safeguards simple, stable.But be must change or regeneration because charcoal absorption reaches capacity, operating cost is relatively high, and the adsorption capacity of active carbon is easily subject to moisture, dust and other impurities in foul smell to affect and decline.
What in chemical method, commonly use is liquid absorption method, adopts the solution such as NaOH, clorox to absorb the odorant in waste gas.The exhaust-gas treatment scheme that company provides for sewage treatment plant is supporting at present adopts caustic wash tower mostly, in order to remove the hydrogen sulfide in waste gas.But because alkali washing method can consume a large amount of alkali lye, and treatment effect is bad, the pump of alkali cleaning simultaneously also easily corrodes and breaks down, and therefore the caustic wash tower of in fact a lot of sewage treatment plants is in idle state.
Bioanalysis is the most frequently used deodorizing method, mainly contains biofilter and aeration type activated sludge process.Biological filter process is current most widely used biologic deodorization method.The foul smell of collecting is first passed through and adds wet process, then by covering with biological filtering layer microorganism, moistening porous, odorous substance, by packing material absorbing, is then resolved into carbon dioxide and other inorganic matters by the microorganism on filler, thereby reach the object of deodorizing.Biofilter operational effect is stable, and investment and operating cost are all lower, but floor space is large, and the civil engineering time is long, and anti impulsion load ability is large poor, once and in pond in service the biological growth of fixed growth bad, replacing is not easy very much.Aeration type activated sludge process refers to foul smell is passed into aeration tank, utilizes the metabolism of activated sludge in aeration tank to remove odorant.But exhausted air quantity often exceedes the needed air capacity in aeration tank, and waste gas need to be pressurizeed for overcoming the depth of water, not only consume a large amount of energy, and the corrosivity of waste gas will be damaged expensive air blast.
Summary of the invention
The invention discloses a kind of waste bio-treatment novel process, exist operating cost higher in order to solve in existing exhaust gas treatment technology, maintenance cost is high, complicated operation, the shortcoming that clearance is low.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
A kind of waste bio-treatment system, is characterized in that, comprises, and the biological scrubbing tower of a waste gas, wherein waste gas gas is connected with the air inlet of the biological scrubbing tower of waste gas by exhaust gas fan; The gas outlet of the biological scrubbing tower of waste gas is arranged or is connected with follow-up dry type deodoration system unit according to demand with directly outer; One aerobic system activated sludge is connected by the biological scrubbing tower of spray pump and waste gas, and spray liquid is connected with aerobic system pipeline; Described waste gas biosystem specifically comprises: the biological scrubbing tower of a waste gas, and in order to carry out filler to increase gas-liquid contact area.
A kind of waste bio-treatment system, is characterized in that, comprising: a scrubbing tower, and described wash tower bottoms is provided with an air inlet, in order to receive waste gas; In described scrubbing tower, be provided with successively from top to bottom an one-level packing layer, an one-level spraying layer, a secondary packing layer, a secondary spraying layer; One demister.
The biological scrubbing tower of waste gas as above, is characterized in that, described secondary spraying layer and described one-level spraying layer are all connected with one or two waterpipes that settle out.
The biological scrubbing tower of waste gas as above, is characterized in that, described one-level packing layer and described secondary packing layer are made by polypropylene material.
The biological scrubbing tower of waste gas as above, it is characterized in that, described scrubbing tower utilizes the basicity of aerobic system activity mud to carry out spray washing, hydrogen sulfide in removal waste gas etc., simultaneously by the microbial metabolism activity of the suspension growth odorous substance of degrading, the mud mixed liquid of the materials such as the sulfide hydrogen after washing flows into aeration tank, changes hydrogen sulfide into sulfate radical removed by blast aeration.
In sum, owing to having adopted technique scheme, the operating cost that waste bio-treatment system of the present invention has solved existing exhaust gas treatment technology existence is higher, complicated operation, the problem that clearance is low, technology disclosed by the invention is utilized the abundant basicity of sewage treatment plant's aerobic activated sludge and microbial resources dexterously, and operation is flexible, usefulness is stablized secure, is very suitable for waste bio-treatment.
Brief description of the drawings
