Description
(1) technical field
The present invention relates to environmental protection protection sewage treatment area, particularly a kind of fermentation tail gas comprehensive utilization Apparatus and method for.
(2) background technology
Along with being the modern biotechnology fast development of representative with genetic engineering, cell engineering, enzyme engineering, Fermentation Engineering, the biofermentation goods have become invests one of industry active, the most with fastest developing speed in 2l century.Because of the biofermentation medicine has the curative effect height, toxicity is low, characteristics such as few side effects, and be widely used in clinically, even will progressively replace some chemical synthetic drugs, for human health is played a greater and greater role.Big because of biological medicine fermentation air consumption simultaneously, as produce the enterprise of 600 tons of cephalosporin sodium salts per year, air use amount hourly is up to more than 30000 cubes, but in process of production, airborne oxygen utilization rate only is about 10%, and produce a spot of carbon dioxide, the tail gas that is untreated in a large number enters atmosphere, the part fermentating metabolism product is taken out of with tail gas, even there is special bad smell to produce, have a strong impact on the normal life of surrounding resident, the concentration of other metabolites of the drug ingredient in the tail gas or intermediate concentration and microorganism thereof constantly raises in air simultaneously, and human body and environment are produced harm.Therefore, must administer its fermentation tail gas.
The fermentation tail gas complicated component, processing method both domestic and external is few, is difficult to find thorough, an economic reasonable plan.Film filter abroad generally is installed behind the fermentation tank tail gas gas-liquid separation device again, film filter separative efficiency height, but the exhaust sterilization steam that fermented etc. influence membrane filtration weak point in service life, maintenance cost height; And for tail gas, the pressure drop resistance is big, and this will bring a series of problems, and at first the air compressor machine outlet pressure increases, and power consumption increases greatly, and the fermentation tank pressure increases, and will bring the influence that can not estimate to producing the bacterium metabolic process in the jar.Domestic enterprise also is not fully recognized that loss and the harm in the exhaust emissions process, the general direct emptying of tail gas, and the mode of production is more extensive.What measure was arranged also just adopts general inefficient cyclone separator and spray absorber.The spray absorption plant often adopts in general Chemical Manufacture, and in medical fermentation tail gas discharging, use, efficient low, easily produce drawbacks such as absorbent secondary liquid foam entrainment loss and operating cost height, simultaneously, the huge fermentation tail gas of quantity directly discharging is the significant wastage of resource.
The mode of current a large amount of production wastewater treatment is biochemical process in addition, and especially to adopt biochemical mode be most economical to a large amount of high concentrated organic wastewaters that produce at fermentation industry.The mode of biochemical treatment is divided into anaerobic and aerobic, and simple anaerobic system can not directly handle and reach discharging standards, so aerobic system is all sewage treatment plant's necessary way.No matter it is catalytic oxidation, activated sludge that sewage aerobic is handled workshop section, or processing mode such as biofilter all need adopt air blast that sewage is carried out oxygenation, to guarantee the normal life of aerobic microbiological, has improved the expense and the cost of sewage disposal so greatly.For example, 5000 tons of waste water of a daily handling ability, require waste water COD from 2500 drop to 300 o'clock oxygen demands be approximately 600 kilograms/time, the utilization rate of oxygen is pressed 10-15% and is calculated, need air capacity be near 20000 cubes/time, the power that the blower fan that can produce these air quantity (the blower fan supercharging is by 7 meters water gages) then needs to dispose is near 600kwh, nearly ten thousand yuan of the power costs of every day, and this obviously is a very big expense.Even fermentation tail gas adopts simple cyclone separator separate discharge, still be that waste is serious.
(3) summary of the invention
The present invention provides a kind of smell that can handle fermentation tail gas can carry out the fermentation tail gas comprehensive utilization Apparatus and method for of Aerobic Process for Treatment again to sewage in order to remedy the defective of prior art.
The present invention is achieved through the following technical solutions:
A kind of fermentation tail gas comprehensive utilization equipment, it is characterized in that: comprise the fermentation tail gas surge tank, fermentation tail gas surge tank one side is connected with cyclone separator, and cyclone separator is connected with fermentation tank by gas pipeline; Fermentation tail gas surge tank opposite side is connected with biochemistry pool by the gas connection pipe road, and biochemistry pool is provided with gas distribution pipe at the bottom of the pond, and the biochemistry pool water outlet enters sedimentation basin, and the sedimentation basin bottom is connected with biochemistry pool by sludge return pipe.
Gas connection pipe road between fermentation tail gas surge tank and the biochemistry pool is provided with check-valves.
Use the method for this fermentation tail gas comprehensive utilization equipment, it is characterized in that: by the fermentation tail gas of fermentation tank generation, be transported to cyclone separator through gas pipeline, after the cyclone separator separation, fermentation tail gas enters the fermentation tail gas surge tank, after fermentation tail gas cushions in the fermentation tail gas surge tank, is entered the gas distribution pipe of biochemistry pool by check-valves by the gas connection pipe road, biochemistry pool is carried out oxygenation, and handle the smell of fermentation tail gas by biochemical sludge; The biochemistry pool water outlet enters the sedimentation basin post precipitation, and biochemical sludge is back to by sludge return pipe and continues in the biochemistry pool to use.
The present invention is by in the biochemistry pool of fermentation tail gas being introduced Waste Water Treatment, fully mix through muddy water, and the organic pollution in the active biochemical sludge absorption fermentation tail gas utilizes remaining oxygen in the tail gas to carry out organic pollution in the oxidation Decomposition waste water again.Through fermentation tail gas oxygenic aeration constantly, organic pollution in the tail gas is just degraded by the active biochemical sludge absorption, muddy water mixed solution flows into sedimentation basin in the pond, waste water after the separation enters follow-up sewage treatment process, and the biochemical sludge that precipitates and isolates is back to by sludge return pipe and continues in the biochemistry pool to use.The oxygenation of aerobic sewage disposal utilizes fermentation tail gas to finish, and other pollutants of fermentation tail gas in the process of oxygenation by the aerobic microbiological biodegrade.
The invention has the beneficial effects as follows: this fermentation tail gas comprehensive utilization Apparatus and method for, with the fermentation tail gas after existing the processing, be incorporated into and replenish the necessary oxygen part of microorganism in the aerobic biochemical pond, and on the gas connection pipe road, be added with check-valves, prevent to flow backwards, so both solve the pollution problem that the discharging of fermentation tail gas brings, reduced the power consumption problem in aerobic biochemical pond again.
