Treatment method for solid garbage

Abstract

The invention relates to the technical field of garbage treatment, in particular to a treatment method for solid garbage. The method comprises the following steps that A, the solid garbage is centralized, and large piece impurity removing is conducted firstly; B, after impurity removing, the garbage is subjected to first-level crushing and crushed into pieces with the grain size below 40 mm, and iron removing and winnowing are conducted; C, materials enter the second-level crushing procedure, and the materials are subjected to fine crushing; and D, after fine crushing, the materials enter a screening procedure, and the materials are screened into three continuous grades including 5-10 mm, 10-20 mm and 20-40 mm according to the grain size. Movable equipment is adopted for aggregate crushing, and noise is low; finished aggregate is placed in a totally-closed silo; dust is prevented from being raised up through a conveying belt and a protection cover; at the dust releasing point, an advanced PPDC is adopted, and the dust removing efficiency is high; due to the workshop partition wall design, noise elimination treatment is conducted on the surfaces of double layers of walls, and noise elimination materials are arranged in a lining manner so as to prevent noise from being diffused; and large-area green belts are planted on the periphery of a plant, the noise elimination and dust suction functions are achieved, and the environment of the plant can be beautified as well.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a treatment method for solid garbage. Background technique [0002] With the continuous development of the economy, the output of urban waste in my country is increasing year by year. The solid waste not only occupies a large amount of land, but also the cost of waste removal is extremely high, which wastes manpower and material resources. At the same time, the process of disposing of waste and piling up waste will generate dust. Dust and sand cause environmental pollution. How to effectively treat and discharge construction waste at the source of solid waste has become an important issue faced by construction companies and environmental protection departments; completely solving the problem of construction waste is an environmental protection issue that we must seriously study and solve. Contents of the invention [0003] The purpose of the present invention is to pr...
