Abstract

The invention provides a construction method of a leachate regulating system. The method comprises the following steps that after leachate regulating tank earth is excavated and rolled, a leachate monitoring well is set on one side of a leachate adjusting tank; a first filament geotextile layer and a gravel guiding and discharging layer are sequentially laid on an original base layer after rollingis completed; the gravel guiding and discharging layer communicates with the leachate monitoring well through a first pipeline; and an anti-seepage clay layer, a sodium-based geosynthetic clay linerlayer, a second filament geotextile layer, a first HDPE film layer, a third filament geotextile layer and a second HDPE film layer are sequentially laid on the gravel guiding and discharging layer. According to the method, the gravel guiding and discharging layer is laid on the original base layer, and the pipeline is connected between the guiding and discharging layer and the monitoring well so that underground water can be well drained; and the HDPE film layers are used as the main impermeable layers, and the rest is used as transition layers to filter the polluted underground water seepage,so that water in the adjusting tank can be effectively prevented from permeating downwards and the polluted underground water is prevented from permeating into the tank.

Description

technical field [0001] The invention relates to the technical field of anti-seepage of regulating pools, in particular to a construction method of a leachate regulating system. Background technique [0002] Sanitary landfill of municipal solid waste is a treatment method widely used at home and abroad. Atmospheric rainfall infiltrates the landfill body and groundwater intrusion within the landfill area, and the degradation water from the decomposition of the waste itself constitutes the landfill leachate. .The landfill leachate is high-concentration organic wastewater with dark brown appearance and severe stench. Whether the leachate is collected and treated to make it pollute the environment to an allowable level is one of the essential differences between sanitary landfills and general landfills. The main source of leachate is atmospheric precipitation. Annual atmospheric precipitation has obvious inhomogeneity in terms of time and quantity, and the daily processing capac...
