Abstract

The invention relates to a biological deodorizing composite filler which is prepared from the following materials by weight percentage: 20-30% of urban abandoned construction waste, 30-40% of high-calcium coal ash, 20-30% of leaf powder, and 10-20% of an adhesive. According to the invention, various components are sufficiently and uniformly mixed, and the mixture is put into a die to be extruded into a porous cylinder, and can be used after being dried. The filler has relatively high mechanism strength, and is good in stability, good in caking property, long in service life, relatively low incost, strong in buffering capacity, rich in organic nutrients, good in air permeability, and remarkable in deodorizing effect.

Description

technical field [0001] The invention belongs to the technical field of deodorizing fillers, and in particular relates to a biological deodorizing composite filler and a preparation method thereof. Background technique [0002] The filler is one of the core components of the biological trickling deodorization device, and it is the carrier for the growth of microorganisms and the transfer of substances, and its performance directly affects the purification effect of exhaust gas. In the current deodorization technology, the fillers used mainly include organic fillers, inorganic fillers and composite fillers. [0003] Traditional organic fillers such as soil, compost, peat, wood chips, corncobs, etc. can provide microorganisms with organic matter as a nutrient source, and there is no need to add nutrients to microorganisms during operation, but they are often damaged due to the decomposition of organic matter during operation. This will lead to the collapse and compaction of th...
