Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] Such as figure 1 As shown, the present invention adopts a pure physical and chemical treatment process without incineration, adopts a fully enclosed operation, and dust removal, noise, dust and sewage control meet environmental requirements.

[0025] The usable part of construction waste accounts for 85%, including concrete, broken bricks, wood, glass, ceramics, paper packaging, plastics, and dust, etc., which can be recycled after treatment. The unusable part accounts for 15%, which is transported to the landfill for safe landfill after crushing and sorting.

[0026] The construction waste recycling product line of the present invention is divided into four categories, which are respectively a recycled micro-powder production line, a block forming production line, a water-stabilized mixture production line and a fuel rod production line.

[0027] The recycled micr...

Abstract

The invention discloses a construction waste treatment method. The construction waste treatment method comprises the following steps of 1, manual sorting and robot sorting, 2, primary crushing, 3, iron removing and winnowing, 4, secondary crushing, 5, screening and 6, joint powder grinding. According to the construction waste treatment method, the problems that a lot of land is consumed, and air dust, sewage pollution and the like are produced due to landfill of construction waste are solved, and construction waste recycled materials are produced.

Description

technical field [0001] The invention belongs to the field of waste treatment, in particular to a construction waste treatment method. Background technique [0002] The national "Twelfth Five-Year Plan" mentions the development of circular economy, insists on equal emphasis on development and conservation, and gives priority to conservation. In accordance with the principles of reduction, reuse, and recycling, in the links of resource exploitation, production consumption, waste generation, and consumption, gradually Establish a resource recycling system for the whole society.
