Problems solved by technology

[0007] Method 1 is discontinuous conveying operation. The mud transportation method has many procedures and low production efficiency. It is generally suitable for occasions where the moisture content of the mud is low or the conveying distance is too long, and the processing cost is relatively high.
Especially in the narrower river section, the amount of silt transportation is large, and it is often impossible to implement
[0008] Method 2: Pipeline transportation can be used

Embodiment Construction

[0023] The dotted line in Figure 1 is part of the technological process realized on the dredger.

[0024] The specific process steps of the present invention will be described in detail below in conjunction with FIGS. 2 , 3 and 4 .

[0025] For river dredging, use the cutting machine on the dredger to cut and stir the soil layer at the bottom of the river to loosen the soil layer at the bottom of the river. Specifically as shown in Figure 2, in the river course to be rehabilitated, the process equipment of the present invention is installed on the dredging dredger in the river course, and the cutter 12 of the cutter 1 is placed directly below the ship, and extends to the soil layer at the bottom of the river until Mixed into the soil layer at a certain depth, driving the screw rod 11 of the reamer, linked with the cutter 12 below, reaming and stirring the river bottom soil layer, so that the soil layer becomes loose and thick mud; the suction pipe 21 extends into the thick tu...

Abstract

The invention discloses a river bottom mud dredging dewatering process technology that includes the following steps: dredging river bed, separating mud and sand, separating sand and water, dewatering and sterilizing. The processed water could reach the discharging standard, and could be recycled. It supplies a entire, low cost and high value method to treat river course.

Description

technical field [0001] The invention relates to the field of environmental protection engineering, in particular to an integrated dehydration treatment process for river channel dredging bottom mud. technical background [0002] With the rapid development of social economy, the urban population has increased sharply, and the amount of sewage discharged to urban waterways has increased significantly, making water pollution more and more serious, and the water environment is deteriorating day by day. The regulation of the river is imminent and directly related to the living environment of the residents. [0003] To improve the river course, two basic tasks need to be done: one is to reduce the discharge of pollutants to the river course, and the other is to dredge the sediment deposited in the river course for many years. The reduction of pollutant discharge requires the supervision of government departments, mainly administrative measures; while the dredging, dredging and se...
