Lake dredging bottom-mud dewatering integrated treatment technology

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...

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 for continuous transportation and high production efficiency. It is generally suitable for high mud moisture content. If the average distance of mud transportation is less than 20km, a sediment treatment station needs to be set up; however, the site of the sediment treatment station is difficult to solve and difficult to implement. , and the sediment treatment station has an odor, and there is mud water leakage during the transportation process, which affects the environment
