Problems solved by technology

However, incineration will produce toxic ash, especially hazardous waste such as boiler fly ash
In addition, due to the high moisture content of the garbage, the incineration method is used to treat municipal solid waste. In order to increase the furnace temperature, the amount of auxiliary fuel needs to be increased. The auxiliary fuel consumption and plant power consumption rate are high, and incomplete combustion products and toxic substances in the exhaust gas High content, causing secondary pollution to the surrounding environment

Abstract

The invention discloses an organic waste treatment technology. The technology comprises the following steps of 1, collecting organic waste and performing pre-treatment; 2, supplying the pre-treated organic waste into a combustion furnace for combustion, introducing combusted gas into a filter for desulfurization and denitration treatment, and feeding combusted residues into a fermentation bin forfermentation; 3, exhausting the filtered gas into air, manufacturing the fermented product into fertilizer. The treatment technology is simple, the environment-friendly performance is good, toxic substances cannot be discharged into air or soil in the treatment process, and popularization is convenient.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to an organic waste treatment process. Background technique [0002] With the acceleration of urbanization and the continuous expansion of urban population, the amount of municipal solid waste is increasing rapidly. Generally, municipal solid waste can be divided into 9 categories, including kitchen waste organic matter, inorganic matter, paper, cloth, plastic, rubber, metal, glass, bamboo and wood, among which the last 7 types are recyclable waste. Perishable kitchen waste organic matter and high moisture content are common characteristics of urban domestic waste in my country. With the improvement of residents' living standards, inorganic matter has declined rapidly, the proportion of perishable organic waste has increased significantly year by year, combustible matter has increased rapidly, and waste with high calorific value (such as plastics and paper, etc.) wi...
