An ecological treatment method for landfill waste mud

Abstract

The invention discloses an ecological treatment method for landfilled waste mud. The method includes the steps of setting up trestles, laying bamboo rafts, conducting field engineering, laying woven geotechnical cloth, inserting drainage boards, arranging drainage channels, arranging drainage connecting bands, laying non-woven fabric, carrying out high-pressure aerosol drainage, laying an isolating membrane, laying non-woven fabric, backfilling plain clay, filling in pure water and accordingly completing ecological treatment. By adoption of the ecological treatment method, mud ecological treatment can be conducted efficiently, rapidly and conveniently through layered dewatering consolidation+ecological clay backfilling+pure water returning, and the ecological environment is restored. A clay interlayer can effectively isolate original mud from a water body, water body safety is guaranteed, and the safety operation and eco-environment protection requirements put forward by owners can bemet at the same time. A high-pressure aerosol patented technology is adopted in the layered dewatering consolidation, construction period dewatering can be effectively accelerated, the construction period is greatly shortened, the construction method is simple and reliable, and post-construction foundation soil bearing capacity is improved. The construction safety can be guaranteed, and the trestles and a bamboo raft network are used for guaranteeing the construction period safety.

Description

technical field [0001] The invention relates to an ecological treatment method for landfill waste mud, and belongs to the technical field of classification treatment and resource utilization of imaging waste. Background technique [0002] With the acceleration of China's urbanization process, there are a large number of construction projects in urban areas every year, and the waste mud generated by construction is also increasing significantly. Due to multiple sources, multiple management links, and multiple responsible entities, construction mud often cannot be properly disposed of. Traditional construction mud disposal is mainly to simply use aircraft fish ponds or low-lying farmland to directly fill and stack it, but its impact on groundwater and Surface water will have adverse effects and seriously endanger the surrounding ecological environment. In addition, the country puts heavy pressure on environmental protection issues, so how to safely dispose of the landfill wast...

Due to multiple sources, multiple management links, and multiple responsible entities, construction mud often cannot be properly disposed of. Traditional construction mud disposal is mainly to simply use aircraft fish ponds or low-lying farmland to directly fill and stack it, but its impact on groundwater and Surface water will have adverse effects and seriously endanger the surrounding ecological environment. In addition, the country puts heavy pressure on environmental protection issues, so how to safely dispose of the landfill waste mud has become a thorny problem
