Problems solved by technology

Landfill occupies land resources; due to the high moisture content in domestic waste, the incineration calorific value is low, and the safety hazards in the incineration process are high
In order to solve the problems of long transportation distance, high cost, and heavy pollution of domestic waste, the present invention has developed and designed a technical method for on-site disposal of domestic waste. Transformation and decomposition, with the characteristics of fast, high efficiency, low temperature, etc., thus realizing the efficient harmless and reduction of domestic waste

Abstract

The invention provides an in-situ low-temperature treatment technology for urban and rural mixed household garbage. The urban and rural mixed household garbage is intermittently added, organic substances in the mixed household garbage are efficiently reduced and harmless through an electromagnetic heating treatment technology, and daily production and daily clearing of the urban and rural mixed household garbage can be effectively achieved, and in-situ treatment is achieved. The in-situ low-temperature treatment technology has the beneficial effects that the treatment technology is simple in process and easy to operate, organic waste is harmless, the reduction speed is high, the effect is good, generated waste gas is discharged after being treated and reaching the standard, and no dioxin is generated; and the whole treatment process is free of secondary pollution to the environment, and obvious economic, social and environment benefits are achieved.

Description

technical field [0001] The invention relates to a low-temperature treatment method for mixed domestic garbage, in particular to an in-situ low-temperature treatment technology for urban and rural mixed domestic garbage. Background technique [0002] Household waste is difficult-to-use substances produced in the process of human life, mainly including kitchen waste, fruit and vegetable waste, waste paper, packaging boxes, plastic products, wood products, metal products, glass products, dust and so on. Although we have established garbage sorting, for remote villages, the villagers have a low level of knowledge and it is difficult to carry out garbage sorting. At the same time, the garbage transportation distance in these areas is long, resulting in high costs and pollution during transportation. It also created a serious financial burden. [0003] The existing garbage disposal methods include landfill, incineration and other methods. Landfill occupies land resources; due to...
