Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the examples.

[0028] An environmentally friendly treatment method for domestic waste, characterized in that the specific steps are as follows:

[0029] Step 1: Spread lime on the domestic garbage entering the yard for disinfection and antisepsis to inhibit the decomposition of organic matter;

[0030] Step 2: Sorting domestic waste: After the screening process, the methods include gravity separation, magnetic separation, and manual separation. Gravity separation includes coarse sieve, medium sieve and fine sieve to obtain the sieve of coarse sieve, medium sieve and fine sieve. The upper and lower sieves are screened to separate organic matter, inorganic matter, magnetic materials, and organic fermented matter from mixed garbage;

[0031] Step 3: The large-grained inorganic matter in...

Abstract

The invention belongs to the technical field of environment protection, and particularly relates to an environment-friendly treatment method of domestic garbage. The method comprises the steps that sterilization and anti-corrosion operations are performed, and organic matter decomposition is inhibited; the domestic garbage is shorted and crushed; lime, bonding agents and combustion improvers are added; the materials are mixed; pressing forming or extrusion forming is performed; solidification is performed; formed and solidified block materials are stacked, and are naturally dried in the air; the block materials which are dried in the air are used as low calorie fuel, coal materials or pavement brick base materials for cement production, and are fed into a rotary kiln and a vertical kiln to be directly combusted. The method is used for solving the problems of secondary pollution in the domestic garbage treatment process and useful ingredient waste after the treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to an environmental protection treatment method for domestic garbage. Background technique [0002] The amount of urban domestic waste in my country is increasing at an average annual rate of 9%, and the average annual growth rate of some urban domestic waste is 15-20%. The per capita daily domestic waste is 1.16kg. The amount of domestic waste piled up around the city has reached more than 6 billion tons over the years, occupying at least 500 million square meters of ground. Now, the newly increased urban domestic waste in the country is placed in simple landfills or open-air piles in the suburbs of cities and along rivers. More than 80 million tons. At present, domestic and foreign domestic waste treatment basically adopts three methods: incineration, composting, and sanitary landfill. Secondary pollution; composting method: a large amount of toxic an...
