Description
Technical field
The invention belongs to the equipment that utilizes bioreactor for treatment waste gas, particularly a kind of integral baffle bioreactor waste gas treatment equipment and waste gas processing method.
Background technology
Human being's production, life activity or nature are discharged all contaminations to atmosphere, the present scale that whole world every year has reached 2,000 ten thousand t/a to the VOC and the odorant of airborne release, the discharging of China's volatile organic contaminant and odorant also increases year by year along with the development of industrial and agricultural production.These volatile organic contaminants and odorant spill in the atmosphere, not only cause the pollution in some areas, and air quality is worsened, owing to along with the diffuses flow of air arrives everywhere, also can bring regional influence.
Be the protection atmospheric environment, some developed countries have worked out relevant environmental protection law, the discharging of pollutant in the strict control waste gas, and require enterprise before discharging pollutants, should take corresponding control measures.China in 1993 and country's " odorant pollutant discharge standard " of coming into effect in 1997 (GB14554-93) and " discharge standard of air pollutants " strict regulation has been made in the discharging of volatile organic contaminant and odorant in (GB16297-1996).
Compare with other physical chemistry waste gas processing method, bioremediation has advantages such as cost is low, easy and simple to handle, technology cleaning, non-secondary pollution because of it, and the nineties becomes the focus of current research later on.Biological ratio juris is to utilize the biological oxidation of microorganism that the smelly material in volatile organic contaminant or the foul gas is converted into carbon dioxide, water and the low process that does harm to the class material.Microbial suspension in the bioreactor is grown in the solution as activated sludge, or apposition growth is in inorganic filler (as: gravel, haydite, active carbon) or organic filler (as: bark, wood chip, compost, resin etc.).
Composite type bioreactor waste gas processing equipment (number of patent application: 01141503.7) constitute by floated bioreactor and fixed type biological reactor, in two parts reactor, the microorganism of pollutant is inequality in the degraded waste gas, they are the water miscible difference according to pollutant in the waste gas, cultivate selectively.Microorganism in the floated bioreactor is to be suitable for suspension growth bacterium in water, that help hydrophily contaminant degradation in the waste gas; Fill filler at the fixed type biological inside reactor, the microorganism of degradation of contaminant is the fungi of apposition growth on filler.Cultivate fungi and replace bacterium, help the removal of hydrophobic contaminant in the waste gas.Therefore, composite type bioreactor waste gas processing equipment can be removed hydrophily in the waste gas and hydrophobic contaminant effectively simultaneously.Thereby the purpose that realization is removed the multiple pollutant in the waste gas simultaneously effectively.And, can realize simultaneously in the floated bioreactor that aeration, gas are prewetted and transfer and the degraded of pollutant from the gas phase to the water soluble in water, reduce auxiliary equipment.Replace bacterial degradation waste gas with fungi in the fixed type biological reactor.On the one hand, fungi can generate mycelia in air, mycelia to around distribute and form the mycelia net, help to increase the contact area of pollutant and mushroom in the gas phase, pollutant in the gas phase is directly fully contacted with fungi in bioreactor, finish mass transport process better.Particularly for some organic exhaust gas, the degradation capability of fungi is higher than bacterium.On the other hand, fungi is stronger to the adaptability of humidity and pH value.Treatment facility spray number of times is few, reduces energy consumption.Composite type bioreactor waste gas processing equipment has compact conformation, structure is succinct, floor space is little, operation and the simple advantage of maintenance.
But, composite type bioreactor waste gas processing equipment following to the biological odor treatment device of streaming, the lower end of its fixed type biological reaction zone only is provided with an exhaust outlet, there is not delivery port, to the microorganism spraying nutrient solution on the filler of fixed type biological reaction zone the time, excess liquid is also discharged from exhaust outlet.During draining, usually hinder gas purging.Therefore, during the spray operation, air pump must cut out usually, make waste gas treatment equipment be in halted state, cause treatment of waste gas not carry out continuously like this.The filler of fixed type biological reaction zone bottom also usually can be discharged exhaust outlet with water, causes the loss of filler.In addition, be positioned near the filler of air communicating pipe import and can enter into communicating pipe, cause the communicating pipe blocking problem.
Summary of the invention
The objective of the invention is to overcome the following defective that exists to the biological odor treatment device of streaming of combined biological waste gas treatment equipment, provide a kind of not only can be easy and simple to handle, energy consumption is lower, can be effectively that concentration range is big, the hydrophily and the lyophobic dust that contain in the waste gas remove simultaneously, and gas, spray liquid are effectively separated, prevent that filler runs off and breather pipe stops up, the integral baffle bioreactor waste gas treatment equipment that spray operation and exhaust-gas treatment can be carried out simultaneously.
Another object of the present invention provides utilizes the integral baffle bioreactor waste gas treatment equipment to carry out the method for exhaust-gas treatment.
