Solid waste material zoning landfill process

Abstract

The invention relates to a solid waste material zoning landfill process. The solid waste material zoning landfill process comprises the following steps that solid waste material to be landfilled is analyzed and tested, the solid waste material is divided into material capable of being directly landfilled and material to be pretreated according to a test result, the material capable of being directly landfilled directly enters a landfill procedure, the material to be pretreated enters a pretreatment procedure and then enters a landfill procedure after reaching the standard, the solid waste material meeting the requirements is fed into a landfill site, and the material is sequentially subjected to zoning landfill till all landfill units are filled with the material. Compared with the prior art, the landfill process has the advantages that before the solid waste material is landfilled, the solid waste material is detected and analyzed firstly, and the unqualified solid waste material is treated and then landfilled, so that the proportion of harmful substances contained in the landfilled solid waste material is reduced, and the harm to soil is reduced.

Description

technical field [0001] The invention relates to the field of solid waste treatment, in particular to a zonal landfill process for solid waste materials. Background technique [0002] In recent years, with the development of industry and the improvement of human living standards, the output of solid waste is increasing, and its composition is becoming more and more complex. Countries also attach great importance to the treatment and disposal of solid waste. With the continuous improvement of our country's comprehensive strength, our country has become the largest manufacturing country in the world. A huge amount of solid waste occupies a large amount of land, and the harmful substances in it may cause land and water environment pollution and endanger human health, and the hazards of hazardous solid waste cannot be ignored. How to treat or stabilize these hazardous wastes more effectively, environmentally friendly, and thoroughly has become a major concern in the world today...

Problems solved by technology

[0003] When the above-mentioned landfill method is used for landfilling solid waste, there will still inevitably be certain defects: the above-mentioned landfill industry is actually aimed at the landfill method of fly ash, and as we all know, for There are various types of solid waste, such as domestic waste, chemical waste, etc., there will be solid waste, and among these solid waste, some solid waste will inevitably contain toxic and harmful substances, especially chemical waste. Garbage, and if this solid waste is directly landfilled with the above-mentioned landfill process, it will inevitably pollute the surrounding soil, so it will be necessary to repair the soil in the later stage, which is very troublesome
