Abstract

The invention discloses a mobile contaminated bottom mud bag pocket dewatering and volume reduction treatment method which is characterized by comprising the following steps of: transporting contaminated bottom mud in a river or water reservoir to closed pipeline mixers via an environment-friendly sand dredger or mud pump, throwing a stabilizing and curing agent into the first pipeline mixer, throwing a flocculating and conditioning agent into the second pipeline mixer, finally dewatering and reducing volume of bottom mud in geotex pipe pockets, and curing and stabilizing bottom mud contaminates. After the bottom mud in the geotex pipe pockets is solidified for 7-50 days, the moisture content of the bottom mud reaches less than 55%. The bottom mud in the bag pockets is transported off the site by using a mobile car body. Treatment or resource utilization reaches national relative standards. The technological innovation bridge spot of the method is 'environment-friendly sand dredging + agent + geotex bag pocket dewatering + natural drying of bottom mud + mobile car body'. Not only is the sludge treatment amount large during project implementation process, but also no site area is occupied, the technology is simple, and the operating cost is low. Good economic benefits are achieved.
