Black-odor riverway ecological transformation method utilizing building rubbish reclaimed materials and sludge

Abstract

The invention provides a black-odor riverway ecological transformation method utilizing building rubbish reclaimed materials and sludge. Building rubbish fine aggregates and solidified sludge are combined to manufacture riverway tunnel bottom composite seepage-proofing materials to be paved at a riverway protection slope and the tunnel bottom; building rubbish rough aggregates are used for manufacturing prefabricated porous vegetation concrete blocks; after being solidified, building rubbish fine aggregates and riverway sludge are combined to manufacture green planting soil to serve as planting base materials; building rubbish fine aggregates and riverway sludge are used for prepaing unfired landscape / water purification ceramsite; building rubbish recovery steel is used for manufacturing prefabricated porous vegetation concrete block fixing parts; and large building rubbish is screened to be shaped to serve as building block materials of a side slope platform or protection feet. By means of the method, building rubbish reclaimed materials and riverway sludge are fully utilized, ecological reasonable transformation is carried out on black-odor riverway side slopes, riverway tunnelbottoms and other positions, the water quality of black-odor riverways is improved, meanwhile, the usage level of stone, cement and other traditional building materials is reduced, solid-waste resource utilization is completed, and remarkable economic and ecological benefits are achieved.

Description

technical field [0001] The invention relates to a method for ecological transformation of black and odorous rivers by using recycled materials from construction waste and silt, and belongs to the technical field of ecological transformation of black and odorous rivers. Background technique [0002] With the development of urbanization, a large amount of construction waste will be generated in the process of construction, demolition, decoration and renovation of construction projects, of which concrete and mortar blocks account for 30% to 40%, and bricks and tiles account for 35% to 45%. , Steel accounts for 10%, and others account for 5% to 8%. At present, China produces about 1.55 to 2.4 billion tons of construction waste every year. A large amount of construction waste basically stays in the simple landfill treatment method, which poses serious safety hazards and increases the difficulty of environmental governance. [0003] The appearance of black and smelly rivers is to...

AI Technical Summary

Problems solved by technology

If construction waste and black and smelly river silt are not strictly controlled and properly disposed of, the development at the expense of the water environment and waste of resources does not conform to the basic concept of sustainable development

[0004] At present, there have been no reports on the ecological transformation project of black and odorous rivers using construction waste and silt as two solid wastes
