Below the present invention is specifically described.
Description of drawings
Fig. 1 is for adopting the malodorant treating processes figure of circular fine hair shape contact percolation material of the present invention.
Fig. 2 represents in the circular fine hair shape contact percolation material of the present invention, the shorter filtering material of villus length in the scope of 3～10mm.
Fig. 3 represents in the circular fine hair shape contact percolation material of the present invention, through the fine hair filtering material of microbial immobilized processing.
Fig. 4 represents of the present invention, the porousness perlite medium of diameter about 5mm.
The present invention is made of two steps substantially, and the 1st step is: by the input port, utilize the circulation diffuser, acidity and the alkaline malodorant of high concentration neutralized. The 2nd step is: by being attached with the circular fine hair shape contact filtration material of bacterium, mould, remove the NH of high concentration3、H 2S and methyl mercaptan (CH3SH)。
According to this step, by water distributor is set, regulate moisture, bacterium, mould that input inoculum agent or process immobilization are processed have higher activity.
The 3rd step is, when malodorant enters the acidity of high concentration or alkaline organic reactive tank (2) by malodorant inflow entrance (1), by nertralizer input port (10), drop into pH value conditioning agent, the pH value is adjusted in 6～8 the scope, mix by circulation diffuser (11), by the dispersion dividing plate (3) at middle part, the power set such by hair-dryer are sent to the top with the said mixture material.
According to the 2nd step, will put in the malodorant biological treatment decomposer (14) through the fixing circular fine hair shape contact filtration material (4) of processing and inoculum agent, be provided with water distributor (5) on top. In addition, the ∧ shape dividing plate (7) that is provided for making the malodorant through final processing to flow out. In addition, as required, can in the 2nd step, the biological decomposition groove more than 2 be set.
The invention is characterized in: the malodorant in the 1st step flows into reactive tank (2) afterwards, and the inside of the biological decomposition groove (14) that the processing malodorant in the 2nd step is used is filled with circular fine hair shape contact filtration material (4) and porous perlite (12). In the 1st step, reactive tank adopts the reason of circulation diffuser to be: when high-concentration acidic wastewater or the inflow of alkaline malodorant, by stirring and circulation, the pH value is adjusted to 6～8 neutral degree, thereby prevents that malodorant in statu quo flows in the 2nd step. In addition, the interior dispersion dividing plate (3) of reactive tank that is arranged on the 1st step can make its dispersion, and keep stable when the malodorant inflow porous disc of high concentration, increases the treatment effeciency of malodorant.
In addition, in the 2nd step, the reason that is filled with the circular fine hair shape contact filtration material of processing through immobilization in the biological decomposition groove is: in the 1st step, when the pH value is adjusted to neutral malodorant inflow, malodorant is adsorbed on the circular fine hair shape contact filtration material, lure thus bacterium and mold propagates into, with malodorant bigger contact area is arranged, thereby in the short period of time it is processed, and Another reason is: for the variation of the pH value of the malodorant that produces in the 1st step, change with the organic concentration load, the biology that employing is adhered to by filling porous fine hair shape material, is easy to realize that oxygen is towards the transmission on the whole surface of contact filtration material, and malodorant transmits towards the dispersion on this surface, thereby can be with the gas discharge that purified.
Therefore, the objective of the invention is in the biological decomposition groove, arrange fine hair shape contact filtration material, the organic malodorant of high concentration and ammonia are carried out Transformatin, thereby remove malodorant. For high concentration Organic malodorant, generally adopt active carbon adsorption to process and chemical treatment, but in the present invention, malodorant is not carried out Chemical Pretreatment, and in the 1st step, directly inject.
In general, the high concentration malodorant is that the pH value is 3 acid malodorant, even but find that also the present invention also is suitable in the pH of malodorant value in 3～8 scopes, still can process by this treating apparatus, according to the present invention, owing to saved the expense of regulating the necessary chemical reagent of pH value, catalyst neither be essential in addition, and the leaked-in air of employing own has reduced operating expenses and maintenance management expense in the 1st step like this. But, because the pH value acid or alkaline malodorant of high concentration presents lack of uniformity, as adding caustic soda, sulfuric acid, promote it to decompose by the conditioning agent that is fit to, thereby improve the removal efficient of malodorant.
Aspect nitrogen and the sulphur, the 2nd step of adding bacterial classification plays an important role in removing the biological decomposition groove. Adoptable inoculum agent comprises bacillus cereus, hay bacillus, bacillus licheniformis, Thiobacillus pars intermedia etc. When in the 2nd step, injecting bacterium, in fine hair shape filtering material layer, microorganism takes off matter and oxidation, and organic matter is decomposed, and organic nutrient substance, nitrogen compound carry out nitrite acidizing to be processed, there is being Nitrosomas to carry out in the situation of nitrated processing, remove ammonia by nitrobacteria, this is external to have in the situation that hydrogen sulfide exists, and oxidizing bacteria, Thiobacillus and der Pilz that the sulfuration bacterium forms make element sulphur become lead sulfate, thread sulfur bacteria is as autotrophic bacterium, with H2S is as the energy. Promote the breeding of other Beggiatoa, Thiothrix and mould.
Except above-mentioned steps, if in the 1st step, breeding has the mud of bacterium mould to become black, then must discharge the mud of reactive tank inside. Be provided with mud discharging pipe (13) in the bottom of reactive tank.
Perhaps, adopt in the following manner bacterium, the der Pilz of microorganism used in the 2nd step, realize the method for processing in the fine hair filtering material, this mode is: under 60 ℃ temperature microbial strain culture is carried out aeration-drying, realize afterwards the immobilization processing. Obviously, adopt method method, that in reactive tank, drop into bacterial classification of processing as common immobilization, can realize the through engineering approaches processing.
