Consumer waste reutilization method

Abstract

The invention relates to a recycling method for living garbage which comprises the steps: (1) separating: recoverable materials of big blocks and other materials are sorted out; (2) magnetic separation: magnetic materials like an iron block, etc., are separated; (3) cracking: the garbage materials after being separated are cracked to a granularity that is suitable for a subsequent treatment; (4) air separation: heavy materials and light materials are separated; (5) cracking of the heavy materials; (6) secondary magnetic separation of the heavy materials; (7) recycling of the heavy materials after magnetic separation; (8) cracking of the light materials; (9) firedamp treatment of the light materials; (10) firedamp storage; (11) screening of the firedamp mud; (12) burning treatment of the matters on the screen of the firedamp mud screen and (13) recycling of the matters under the screen of the firedamp mud screen, etc. The recycling method is mainly used for treating the living garbage and can better make use of the materials and energies in the garbage to simplify the treatment process and reduce the treatment cost and the pollution to environment.

Description

technical field [0001] The invention relates to a method for recycling and utilizing domestic garbage, which belongs to the technical field of environmental protection. Background technique [0002] The materials and energy contained in domestic waste can be recovered and utilized in an appropriate way. Due to the complex composition of domestic waste, such as food waste, plastic, metal, glass, ceramics, dust, etc., according to the existing technology, different components Different recycling methods are required. Therefore, there is still a lack of a feasible recycling technology for domestic waste with complex components. Basically, landfill and incineration are used for disposal. These disposal methods have difficulties to overcome. For example, for landfill treatment, a large amount of landfill site needs to be occupied, and there is a risk of pollution such as seepage. At present, it is difficult to find suitable landfill sites for many large and medium-sized cities; f...
