In order to meet the standard, the method is generally adopted to treat the waste liquid by an RTO oxidation method and then treat the waste liquid by a microbial degradation mode so as to achieve the purposes of reducing the concentration of pollutants and meeting the emission requirements of new standards.
The mode of microbial biodegradation is focused on biodegradable organic contaminants among the contaminants. With respect to the nature of the contaminants mentioned above, biodegradation is generally achieved by trickling filtration devices and filtration devices, wherein trickling filtration devices primarily treat water-soluble organic contaminants such as formaldehyde, hydrogen sulfide and the like. The filter device is used for treating organic pollutants which are not easy to dissolve in water, such as benzene series and the like. The waste gas from general medical treatment is first filtered by the drip filter and then filtered by the filter.
The existing filtering device comprises a filter material with microorganisms for treating corresponding organic pollutants, micropores are formed in the filter material for allowing gas to pass through, and waste gas with pollutants passes through the filter material, so that the microorganisms in the filter material can absorb and degrade the organic pollutants in the waste gas in the process, and the concentration of the organic pollutants in the waste gas passing through the filter material is reduced, so that the purpose of purifying the waste gas is achieved. At present, waste gas enters from the bottom of a filter material and is discharged from the top of the filter material, the maximum range of the thickness of the filter material is limited due to the mechanical structure of the filter material, and cannot be too large, so that the stroke of the waste gas passing through the filter material is limited, namely the time of the waste gas passing through the filter material is limited, namely about 6 seconds, the organic pollutants which can be absorbed when the organic pollutants in the waste gas in unit volume pass through one filter material are limited, the treatment efficiency of a single filter material is low, and in order to meet the emission requirement, the waste gas treatment can be realized by arranging a plurality of groups of filter devices connected in series, so that the cost is high.
