Problems solved by technology

[0006] In order to solve the above problems in the prior art, the present invention provides a system and method for deep resource utilization of municipal solid waste. The method of the present invention firstly classifies the waste, obtains materials for different purposes after processing, and separates the organic matter Carry out deep processing into clean diesel oil, and there will be no pollution problems such as dioxin and heavy metals in the process of preparing diesel oil. The oil prepared by this method has low sulfur content, high calorific value, and high flash point. Clean vehicle diesel oil , no waste water, no solid waste, domestic waste is used as an industry, renewable alternative energy is provided, and large-scale industrialization of environmental protection is realized

Abstract

The invention discloses an urban domestic waste deep resource utilization system and method. The system comprises a waste classification system and a resource utilization system, wherein the waste classification system comprises a waste crushing system and a magnetic separation system in sequential connection; the magnetic separation system is respectively connected with a metal recovery system, an inorganic matter recovery system and an organic matter recovery system; the organic matter recovery system is connected with the resource utilization system. By using the system provided by the invention, the urban domestic waste is classified; various kinds of substances are sequentially classified and are sufficiently recovered and reused; the organic matters are subjected to cracking and purification treatment to obtain clean diesel oil, so that the pollution of the waste on atmosphere, water body and soil is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental management and restoration, and in particular relates to a system and a method for deep resource utilization of municipal solid waste. Background technique [0002] Energy and environmental issues are always issues of global concern and need to be solved urgently. With the rapid development of human population towards urbanization and the rapid development of industrial modernization, non-renewable natural resources such as oil, coal, and natural gas have been consumed in large quantities. The problem is becoming more and more prominent, and land resources are becoming more and more scarce. The management and resource utilization of urban domestic waste is a worldwide problem. At present, there is no optimal disposal method that is both environmentally friendly and resource-efficient without occupying arable land. [0003] Municipal solid waste is the complete and ultimate waste of various ...
