The project is located in Changyang Lake, Pingwang Town, Suzhou. The total earth volume of ecological dredging is about 1.553 million m³, and the average dredging thickness is 43cm. The lake-bottom sludge is discharged to the Changyang wetland and Xueluoyang wetland. The ground elevation of the wetland is 2.8m and the normal water level is 3.1m. The sediment contains high eutrophication components which are mainly organic matters such as feed, and this is the main cause of cyanobacteria.
CHARACTERISTICS OF TAIHU LAKE DREDGING
The bottom sediment is complicated, which contains floating mud and iron fine silt
Thin dredging layer with high control precision
Long range of soil discharge
SOLUTIONS
Customize modular-assembly special shallow-water Pneumatic Suction Pump Ecological Dredger for lakes. The pump body of the suction pump adopts the first-class configuration with discharge capacity of 450m³/h
GPS positioning system and water depth detector system are installed above the underwater suction port, and an observation pole is arranged at the upper end of the suction port
Add horizontal conveying pneumatic booster pump
TECHNICAL ADVANTAGES
No secondary pollution such as water turbidity caused by spill and diffusion of floating mud
Precise depth control and thorough removal of contaminated sediment
Mud discharge concentration can reach 1.25~1.30t/m³ (40%-60% of underwater mud volume).The wetland filling and natural drying are fast
The operation platform is modularly assembled and easy to transport
