Comprehensive recycling treatment method of domestic garbage in villages and towns

Abstract

The invention discloses a comprehensive recycling treatment method of domestic garbage in villages and towns. The method comprises the following steps: adopting a garbage sorting collection vehicle to collect putrescible organic garbage and other types of garbage in living areas of the villages and the towns, performing crushing and evenly-mixing pretreatment on the putrescible organic garbage, then performing aerobic static composting and screening after the compost is decomposed thoroughly and becomes stable; and performing compression pretreatment on the other types of the garbage, and then transporting to a garbage incineration power plant for disposal. The garbage compost product can be used for agriculture and forestry production or used as a soil improver for improving the soil manurial effect and the content of organic matters; and the garbage diversion is performed by composting, thereby significantly reducing the garbage incineration amount and reducing pollution risks, such as dioxin and the like. The reduction and harmless and recycling treatment of the garbage can be realized, the potential environmental pollution risk is effectively reduced and the significant social, economic and environmental benefits are realized.

Description

technical field [0001] The invention relates to a method for comprehensive treatment of domestic garbage as a resource. Background technique [0002] With the development of the economy and the increase of farmers' income, major changes have taken place in the rural consumption structure, which has led to a rapid increase in the total amount of rural domestic waste. According to statistics, there are more than 40,000 villages and towns in China, and rural areas account for 90% of the country's land area, with a rural population of about 713 million. According to the survey by the Ministry of Health, the amount of domestic waste generated per person in rural areas is currently 0.86 kg per day, and the annual domestic waste in rural areas across the country is close to 300 million tons. With the implementation of the ecologically civilized village construction, the construction of a new socialist countryside, and the rural well-off environmental protection action plan, the tr...

AI Technical Summary

Problems solved by technology

Due to the high water content, low calorific value, and incomplete combustion of rural garbage, no flue gas purification measures were taken during the incineration process, and a large amount of fly ash, dioxin, carbon monoxide, residues and other toxic and harmful pollutants generated during the incineration process were discharged randomly, causing serious secondary pollution

Domestic waste in villages and towns is mainly collected in a mixed manner, directly mixing perishable organic waste with a high moisture content with other waste, which not only increases the safety hazards of the landfill, reduces the calorific value of waste incineration, but also seriously wastes resources, especially the perishable organic waste. The resource utilization of organic waste has been seriously neglected

On the other hand, due to the lack of understanding and management of domestic waste treatment, the domestic waste treatment and disposal technology is extensive and single, resulting in serious secondary pollution, poor reduction effect, low utilization rate of resources, and the waste generated by rural domestic waste treatment. Environmental problems are becoming increasingly prominent

At this stage, domestic research on the recycling of domestic waste in villages and towns is relatively backward, and there is a lack of mature, economical and effective comprehensive treatment technologies and means
