Cyclic ecological environment-friendly treatment process for forestry and agricultural organic waste and flue gas

Abstract

The invention belongs to the field of environmental protection, particularly relates to a cyclic ecological environmental protection treatment process for forestry and agricultural organic wastes andflue gas, can solve the problem of treatment of forestry and agricultural organic wastes such as straws, provides a cheap and environment-friendly flue gas treatment method, and also provides a cheapraw material for producing carbon-based fertilizer. According to the technical scheme, forestry and agricultural organic waste is gasified and carbonized into biological activated carbon, the biological activated carbon is used for adsorbing harmful substances in flue gas after being pulverized, adsorbed materials and dust are used as carbon-based fertilizer raw materials after being collected, flue gas can be pretreated before adsorption, and adsorbed substances can be subjected to water flotation separation as required after being collected. Resource utilization of agricultural and forestryorganic waste such as straw is achieved, a cheap and environment-friendly flue gas treatment method is provided, the utilization rate of products is increased, the problems of secondary pollution andthe like caused by activated carbon after pollutants are adsorbed are avoided, and the carbon-based fertilizer prepared from the activated carbon adsorbing pollutants such as nitrate and sulfur can improve alkaline soil in the north.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a circular ecological and environmental protection treatment process of agricultural and forestry organic waste and flue gas. Background technique [0002] At present, the random burning of straw and other agricultural and forestry organic wastes has become an urgent problem for the government to solve. Every year, there are many regional pollution incidents caused by straw burning and many traffic accidents. The natural decay of straw will produce a large amount of VOC and cause serious ozone pollution. It is currently the largest source of VOC that causes ozone pollution. bigger. Using straw as feed is a very good way, but because of its large amount, it is difficult to digest. In recent years, some attempts have been made to generate electricity from straw. Due to the high transportation cost and poor efficiency, it must rely on government subsidies to mai...

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a circular ecological and environmental protection treatment process of agricultural and forestry organic waste and flue gas, which can not only solve the problem of straw treatment, but also provide a cheap and environmentally friendly flue gas treatment method, It also provides a cheap raw material for the production of carbon-based fertilizers

Compared with the existing technology of straw biochar treatment of flue gas, the present invention solves the problems of low utilization efficiency of straw biochar and easy generation of secondary pollution, and realizes resource utilization of the processed products
