Abstract

The invention provides biological deodorizing packing and device. The biological deodorizing packing is formed by uniformly mixing biochar, mineralized rubbish and polyurethane at the mass ratio of 2-4:3-5:1-5. The packing density of the biological deodorizing packing is 0.5-1.0g / cm<3>, the particle size range is 5-50mm and the specific surface area is 200-300m<2> / g. The device comprises a washing tower and a biological packing tower which are mutually communicated. The biological packing tower is a sealing container which is formed by vertically stacking and connecting a basic unit and a plurality of reaction units. Each reaction unit comprises a polyurethane packing layer and a biological packing layer, wherein the polyurethane packing layers and the biological packing layers are arranged inside a barrel body, the polyurethane packing layers are made of polyurethane material blocks, and the biological packing layers are made of the deodorizing biological packing. By the adoption of the biological deodorizing packing and device, deodorizing efficiency is improved, starting time is shortened, shock resistance is improved, blockage is not prone to occurring, and the biological deodorizing packing has the advantages of being wide in raw material source, low in cost, simple in preparation and high in reliability, odor of rubbish is effectively controlled, and the biological deodorizing packing and device are suitable for places such as sewage and rubbish disposal plants, slaughter houses, farms and chemical plants.

Description

technical field [0001] The invention relates to a material and a device for waste gas treatment, in particular to a biological deodorizing filler and a device for removing the stench of domestic garbage, belonging to the technical field of environmental protection. Background technique [0002] The content (weight) of organic matter in urban domestic waste in my country is about 50-70% (of which the content of kitchen waste is about 55%, and the content of fruit peel is about 10%), and the main components are hydrocarbons ((CH 2 O) 6 and (CH 2 O) 12 ), protein (C 46 h 77 o 17 N 12 S) and fat (C 55 h 104 o 6 ), etc., showing the characteristics of high moisture content, high organic matter, and perishability. Perishable garbage will release a large amount of malodorous gas during the degradation process, which can be divided into five categories according to its chemical composition: (1) sulfur-containing substances, including hydrogen sulfide, mercaptan, sulfide, e...
