Description
Technical field
The utility model relates to the exhaust-gas treatment field, is specifically related to a kind of emission-control equipment, is applicable to the processing of industrial waste gas.
Background technology
In the Anaerobic Treatment process of waste water, the organic matter in the waste water finally is converted into CH through the acting in conjunction of a large amount of microorganisms
4, CO
2, H
2O, H
2S and NH
3In this process, the metabolic process of different microorganisms influences each other, and mutually restriction forms the complicated ecosystem.The anaerobic degradation process can be divided into four-stage:
Hydrolysis stage: macromolecule organic is huge because of relative molecular mass, can not permeate through cell membranes, therefore can not directly utilize for bacterium.Therefore they are decomposed into little molecule in the phase I by the bacterium ectoenzyme.For example cellulose is cellobiose and glucose by cellulose hydrolyzation, and starch is maltose and glucose by Amylase Hydrolysis, and protein is small peptide and amino acid etc. by protease hydrolytic.These micromolecular hydrolysates can be dissolved in water and permeate through cell membranes is utilized by bacterium.
Fermentation (acidifying) stage: at this one-phase, above-mentioned micromolecular compound is converted into more simple compound and is secreted into the extracellular in the cell of zymogenous bacteria (being acidification bacteria).The primary product of this one-phase has volatile fatty acid (VFA), alcohols, lactic acid, carbon dioxide, hydrogen, ammonia, hydrogen sulfide etc.Meanwhile, the acidifying bacterium also utilizes the part material to synthesize new cellular material.
Produce the acetic acid stage: in this stage, product on last stage is further converted to acetic acid, hydrogen, carbonic acid and new cellular material.
Produce methane phase: in this one-phase, acetic acid, hydrogen, carbonic acid, formic acid and methyl alcohol etc. are converted into methane, carbon dioxide and new cellular material.
According to the utilization of Practical Project, present stage, the exhaust-gas treatment mode of anaerobic system is divided into two kinds:
1, waste gas is delivered to emission-control equipment by exhaust gas fan, by alkali lye is reverse fully contacts with spray, enters atmosphere by exhaust outlet;
This processing mode, often efficient is not high, has large quantity of exhaust gas fully not contact just with alkali lye and enters in the atmospheric environment.
2, exhaust piping is stretched in the aerobic aeration pond, on the waste gas horizontal pipeline at the bottom of the aeration tank, arrange aperture, allow waste gas process by the mode of biochemical treatment.
This processing mode often because the solubility of waste gas is limited, causes waste gas to give out the aeration tank from liquid level.
In the waste gas, main component is H
2S, H
2S is a kind of reducibility gas, with situation that alkali lye fully contacts under, in emission-control equipment, replenish a large amount of mobile air simultaneously, will greatly improve treatment effeciency, save a large amount of alkali lye.
