Biology deodorization filling material and method for preparing the same

Abstract

The invention relates to an atmosphere environmental protection field. A biological deodorization filling material is formed by the piling of the bamboo blocks which are knitted and arranged by the bamboo strips. The surface of the filling material is provided with the carbonization layer which is attached with the activation liquid and the active sludge. The preparation method includes: the bamboo surface is baked, carbonized and knitted into the bamboo plate or the bamboo strips are knitted into the bamboo plates and are then carbonized; the bamboo plates are watered by the activity liquid; the bamboo plates are arranged into the bamboo blocks which are piled into the filling material where the active sludge is splashed. The invention has the advantages of deodorization for the smelly gas, purification of the atmosphere, taking the bamboo with large output and low price as the raw material, having the porous structure and the nutriments, providing the necessary conditions for the growth of the active sludge, adopting the special material for knitting, large specific surface, baked and carbonized surface, fixed active sludge, acidification prevention of active liquid, growth hanging the membrane with the activity sludge, taking the malodor molecule as the carbon source and taking the biomass as other nutriments, thus reaching the atmosphere purification and deodorization effect.

Description

technical field [0001] The invention relates to a technology in the field of atmospheric environmental protection, in particular to a biological deodorization filler and a preparation method thereof, which is used as a source of malodorous gas pollution in sewage treatment plants, poultry farms, leather factories, garbage disposal plants, paint companies, petrochemical companies, etc. Packing for biofiltration reactors for degradation treatment. Background technique [0002] The fillers of biological filters are mainly divided into soil fillers, compost fillers and modified diversified fillers. Soil filling technology is a technology in which malodorous gas passes through the soil and is degraded by microorganisms in it to achieve the deodorizing effect. However, the biological filter of soil filling occupies a large area and soil particles are easy to block the ventilation pipeline, so it is basically no longer used now; composting Originally refers to the pile up of disca...

AI Technical Summary

Problems solved by technology

[0003] The traditional composting filler technology also has its own problems: (1) The accumulation is not neat, so that the contact purification surface area cannot be accurately determined, and it is easy to form a short flow and increase the pressure drop, which reduces the treatment effect and wastes energy; (2) Replacement of the filler The interval time is short and the corrosion resistance is poor; (3) although the occupied area is smaller than that of the soil filler technology, it is larger than that of the modified and diversified filler technology; (4) the filler is not easy to industrialize and the preparation is troublesome
