A kind of system that removes lake silt comprises:
1) dredge boat is used to extract out the mud that is deposited in the bottom, lake;
2) floating pipe waterborne is connected to dredge boat, is used for sending the mud that dredge boat digs out to first concentration basin;
3) first concentration basin is connected with floating pipe waterborne, is used for mud is concentrated, and mud concentration is brought up to 30-35%;
4) mud cargo ship is connected with first concentration basin, and the mud after first concentration basin is concentrated is transported to pumping plant;
5) pumping plant is connected to the mud cargo ship, and mud is transported to dehydrating plant;
6) dehydrating plant is connected to pumping plant, and mud is carried out processed, forms filter cake;
7) the comprehensive utilization station is connected to dehydrating plant, and the filter cake that forms after the processed is fully utilized.
Further, also comprise first gravity filter, the surplus water that first concentration basin is produced carries out filtration treatment.
Further, also comprise second concentration basin and second gravity filter, the desliming water that dehydrating plant is produced concentrates and filters.
Further, first concentration basin and second concentration basin all are arranged on the bank.
Adopt the system's cleaning lake silt in the utility model, can improve the operating efficiency of removing mud; Reduce and remove the pollution that mud produces; Reduce the cost of removing mud.

The specific embodiment
Fig. 1 shows the system and the technological process of removing lake silt.The mud that is deposited in the bottom, lake is extracted out by dredge boat 11, and the weight percent concentration of mud is C1=2-20%, sends first concentration basin 13 on bank to through floating pipe 12 waterborne.First concentration basin 13 is brought up to C2=30-35% to mud concentration.The mud of 30-35% is delivered to mud cargo ship 14 through first passage 31.Mud cargo ship 14 is transported to pumping plant 15 to mud, and pumping plant 15 is transported to dehydrating plant 16 to mud.After mud was handled through dehydrating plant 16, concentration C 3 reached more than 60%, becomes filter cake.Filter cake is transported to comprehensive utilization station 17 through second channel 32 and fully utilizes.
Surplus water solid content SS1≤100mg/L that first concentration basin 13 produces delivers to first gravity filter 18 by third channel 33 and carries out filtration treatment, and the clear water solid content SS2≤70mg/L that filters out flows back to lake 19 by four-way 34.The mud slurry that first gravity filter 18 filters out sends back to mud cargo ship 14 through five-way road 35.
The desliming water that dehydrating plant 16 produces is delivered to second concentration basin 20 through the 6th passage 36 and is concentrated, and the solid content SS3≤100mg/L after concentrating delivers to second gravity filter 21 through the 7th passage 37 then.Clear water solid content ss4≤70mg/L that second gravity filter 21 filters out can be recycled.The mud slurry that second gravity filter 21 produces turns back to dehydrating plant 16 by the 8th passage 38 and carries out filter-press dehydration.
Floating pipe 12 waterborne can move along with dredge boat 11.Assurance dredge boat 11 is worked continuously in same zone.
