Abstract

The invention discloses an emission reduction, collection and processing method for trough-type aerobic composting odors. The method comprises the steps that composting raw materials are added to composting troughs, and odors produced by the composting troughs are collected by a gas collecting hood under the sheltering of a roller shutter, are led into a wind pipe through a draught fan, enter a cyclone dust remover so as to be subjected to dust removal, enter a deodorization tower and then enter a biofilter after the odors are processed by the deodorization tower. The method disclosed by the invention has the advantages that the odor emission can be effectively reduced, and the composting efficiency can be increased; and odor ingredients can be better collected and removed in an open aerobic composting environment.

Description

technical field [0001] The invention relates to the field of odor treatment, in particular to a trough-type aerobic composting odor reduction, collection and treatment method. Background technique [0002] The amount of organic solid waste produced in my country is huge every year. The fresh weight of livestock and poultry manure alone is about 2.5 to 3 billion tons, and the crop straw is about 700 million tons. At present, the utilization of this resource is very insufficient. The livestock and poultry manure discharged by many large-scale livestock and poultry farms is directly discharged into the agricultural ecosystem without treatment, which contains a variety of pathogenic bacteria and parasite eggs, which destroys the agricultural system, pollutes the environment, and threatens the human body. healthy. However, crop stalks are mostly discarded in the vast rural areas except that they are used as fuel and feed for livestock and poultry. If this part of organic solid ...
