Description
Technical field
The utility model belongs to sludge dewatering technical field, is related to a kind of river and lake silt special filtering sheet frame and river and lake silt
Special high-pressure filter press.
Background technology
China region is wide, and in length and breadth, each river course and lake carry the drinking of city, flood discharge, row to city river
The functions such as flood, tourism, shipping, with the rapid development of economy, the utilization of resources is extensive, various industry, house refuse and sewage are not
The phenomenon arbitrarily discharged through handling is of common occurrence, along with soil erosion, causes river channel sedimentation, not only have impact on the basic of river course
Function, if things go on like this, increases the safety and sanitation hidden danger in city.A large amount of sludgd depositions are on the riverbed of city, and such case will be
Long-term existence in regular period.The river in contaminated river course remains in a standstill, river channel sedimentation, and water body is muddy even black smelly show occurs often
As.Originally as life and the urban river water at industrial water water source, its function has been severely impacted.The beautification ring that river course has
The functions such as border, regulation city miniclimate, landscape tourism are also greatly reduced.The deposition in river course, silt up and make shipping, flood control function notable
Degenerate, and the main cause of stream entering lake pollution or most of lake pollutions and eutrophication.Due to the deterioration of river course water environment
Urban life environment and the landscape is not only set to receive destruction, and the heavy damage original function of river ecosystem and stably
Property.Therefore, city river, which is desilted and dredged, attaches most importance to, and carries out water environment improvement comprehensively, very urgent.
During desilting, it is key issue that how the mud of removing, which is handled,.Practice have shown that, mud usually contains substantial amounts of
The material such as organic matter, pathogenic microorganism, heavy metal and nitrogen, phosphorus, due to its poor permeability, mud be difficult to during pressure-bearing by
Pore water is discharged, and long-term immersion forms thick hydrated sheath, causes sludge consolidation difficult, without bearing capacity, and be pressurized easy rheology, is in
Stream modeling shape.Obviously, if it is possible to dehydration and drying is carried out to mud in a short time, its volume is dramatically reduced, not only subtracts
Small transport pressure, while also providing conditioned basic for follow-up disposal.Therefore, the exploitation online drying technique of mud and equipment,
Fast and reliable end disposing technique is formed, to realizing that effective desilting in river lake is very crucial.
