Description

Technical Field

[0001] The utility model relates to the technical field of sludge processing equipment, in particular to an integrated sludge hydraulic dehydration and squeezing equipment. Background Art

[0002] The current sludge solid-liquid separation equipment on the market for trenchless underground is large in size, lacks mobility, and has high cost of use. For example, in trenchless horizontal directional drilling projects, the project sites are scattered, and the amount of sewage generated is not large due to the small amount of engineering. Construction mud, like construction waste and construction wastewater, is one of the three major wastes in the construction process. With the acceleration of urbanization, a large number of trenchless underground pipeline projects are under construction every year, and the construction mud generated by construction is also increasing in large quantities. The mud is difficult to dry naturally in its natural state, resulting in mud all over the construction site, sewage is difficult to manage, and the construction site is chaotic. Due to the multiple sources, management links, and responsible entities, construction mud is often not properly disposed of. If it is directly discharged, it will cause underground pipelines and rivers to be blocked, seriously affecting the natural environment, and have adverse effects on groundwater and surface water, endangering the surrounding ecological environment. If it is directly transported and dumped into a landfill pit without treatment, it will directly increase the transportation cost and road safety of vehicles, and may even cause the risk of landfill pits bursting.
