Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the drawings.

[0054] figure 1 Shows the process flow of removing lake silt. The silt deposited at the bottom of the lake is pumped out by the dredger 11, the weight percentage concentration of the silt is C1=2-20%, and is sent to the first thickening tank 13 on the shore through the floating pipe 12 on the water. The first thickening tank 13 increases the sludge concentration to C2=30-35%. 30-35% of the mud is sent to the mud carrier 14 through the first passage 31. The mud carrier 14 transports the mud to the pump station 15, and the pump station 15 transports the mud to the dehydration station 16. After the mud is processed by the dehydration station 16, the concentration C3 reaches more than 60% and becomes a filter cake. The filter cake is transported through the second channel 32 to the comprehensive utilization station 17 for comprehensive utilization.

Abstract

The invention provides a method and system for eliminating lake sludge. The method comprises the following steps of: 1, pumping sludge deposited on the bottom of a lake by a dredger (11); 2, conveying the sludge to a first concentration basin (13) by a water floating tube (12); 3, conveying the concentrated sludge to a sludge conveying ship (14) through a first channel (31); 4, conveying the sludge to a pump station (15) by the sludge conveying ship (14); 5, conveying the sludge to a dehydrating station (16) by the pump station (15); and 6, treating the sludge by the dehydrating station (16) to obtain filter cakes, and then conveying the filter cakes to a comprehensive utilization station (17) through a second channel (32) for comprehensive utilization. By using the method and system provided by the invention for eliminating the lake sludge, the working efficiency of eliminating the sludge can be increased, the pollution generated by eliminating the sludge can be reduced, and the costof eliminating the sludge can be lowered.

Description

Technical field [0001] The invention belongs to the field of environmental protection, in particular to the field of comprehensive treatment of lakes, and in particular to a method and system for removing lake silt. Background technique [0002] Silt will accumulate at the entrance of the river channel in the lake. After a period of time, the silt will accumulate more and more. The large amount of silt will deteriorate the water quality and ecology of the lake. The silt needs to be removed. [0003] The current sludge removal method is not efficient enough; it is easy to cause secondary pollution during the sludge removal process. Summary of the invention [0004] In view of the above-mentioned problems in the removal of silt, the present invention provides a method and system for removing lake silt with high efficiency, low pollution and low cost. [0005] In order to achieve the above-mentioned effects, the present invention adopts the following methods. [0006] A method for remov...
