Multi-layer flat tube bag rapid dehydration system and dehydration method for mud treatment

Abstract

The invention relates to a multi-layer flat pipe bag rapid dehydration system and dehydration method for mud treatment. The dehydration system includes a drainage platform, and the drainage platform is arranged with a slope; a water collection tank is arranged around the drainage platform. The sump is set at the lower edge of the slope of the drainage platform, and the water on the drainage platform is drained to the sump through the slope; several layers of pipe bags are stacked on the drainage platform, and the pipe bags are filled with water-containing For mud, an interlayer water-conducting layer is arranged between each layer of pipe bags, and a filling port for filling mud into the pipe bags is arranged on the pipe bags; a bottom is provided between the drainage platform and the bottom pipe bag Water guide layer; a water bag is arranged above the top layer tube bag, and the water bag is filled with water. The dewatering system adopts the combination of multi-layer flat tube bag stacking, water bag ballasting and increasing the drainage boundary of the tube bag to achieve rapid dehydration and consolidation of mud.

Description

technical field [0001] The invention relates to a sludge and sludge dewatering system, in particular to a multi-layer flat tube bag rapid dehydration system and a dehydration method for mud treatment. Background technique [0002] River and lake dredging, waterway dredging, and construction of various infrastructure projects will produce a large amount of waste mud. This kind of mud has high water content and huge volume. In order to avoid polluting the environment, it needs to be dehydrated and solidified and reduced in volume. Building a storage yard according to the traditional method to make the silt solidify naturally requires a large area of ​​land, and it takes a long time to dehydrate and solidify. The geotechnical tube bag mud dewatering method refers to sewing woven or woven geotextiles into large-sized tubular bags, setting a filling port on the top of the tube bag, and filling the nearby mud into the tube bag by hydraulic filling. The geotextile sewn into the pi...

AI Technical Summary

Problems solved by technology

When pipe bags are used to treat high-viscosity mud, in the later stage of dehydration and consolidation, the permeability coefficient of the composite composed of bag cloth and mud is low, and the permeability gradient is small, resulting in a slow discharge of water in the mud and a long dehydration cycle. Long, construction period increases
