2) floating pipe waterborne is used for sending mud to first concentration basin;
3) first concentration basin is used for mud is carried out concentrating the first time;
4) mud cargo ship links to each other with first concentration basin by first passage, and the mud after first concentration basin is concentrated is transported to pumping plant;
5) pumping plant is transported to dehydrating plant with mud;
6) dehydrating plant carries out processed to mud, forms to become filter cake,
7) the comprehensive utilization station fully utilizes the filter cake that forms after the processed.
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.
Adopt the method and system cleaning lake silt among the present invention, 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
Below in conjunction with accompanying drawing the present invention is specifically described.
Fig. 1 shows 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.
