Problems solved by technology

[0008] The problem solved by the present invention is to provide a combination of biofilter fillers, so that the existing biofilter fillers make the deodorization process more difficult to control. For the above-mentioned inert materials that cannot provide nutrients, it is necessary to continuously add nutrients. For peat fillers The defects of limited range of pollutant treatment, large floor area and short replacement cycle can be solved at the same time

Abstract

The invention discloses a biofilter packing composition. The biofilter packing composition comprises upper-layer packing and lower-layer packing, wherein the upper-layer packing is prepared from activated carbon, peat and sawdust, and the lower-layer packing is prepared from epidermal fiber structures of arbor plants, shells, zeolite and lava. According to the biofilter packing composition, the upper-layer packing and the lower-layer packing are adopted for layering treatment, the organic matter packing such as the activated carbon, the peat, the sawdust, the epidermal fiber structures of the arbor plants, the shells, the zeolite and the lava and inorganic matter packing are combined together, matching is scientific and reasonable, and therefore the defects that for existing biofilter packing, the deodorization process is difficult to control, nutritional substances need to be continuously put in an inert material which cannot provide nutrients, the pollutant treatment range of the peat packing is limited, large floor area is occupied, and the replacement cycle is short are simultaneously overcome.

Description

technical field [0001] The invention relates to the field of waste gas purification, in particular to a biological filter packing combination. Background technique [0002] Exhaust gas treatment is also called exhaust gas purification. Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before being discharged to the outside, so as to meet the national standards for external discharge of waste gas. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization, disinfection and purification. [0003] Existing waste gas treatment methods include thermal combustion method and catalytic combustion method, liquid medicine absorption method, adsorption method, and biological filter treatment method. 1) The deodorization principle of the thermal combustion method and the catalytic combustion method is that the malo...
