Mobile contaminated bottom mud bag pocket dewatering and volume reduction treatment method

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.

AI Technical Summary

Benefits of technology

This patented method uses environmental cleanings techniques like excavating tunnels on top soil layers with pipes made from materials that absorb water when exposed during construction work hours without causing secondary contamination. It also reduces energy consumption compared to current methods by allowing the deposited liquid to evaporate naturally over time into solid form instead of being absorbed within porous walls inside the pipeline itself. Additionally, this technique allows for easy removal after use while minimizing any negative impacts on surrounding areas due to its ability to recycle waste material back onto the ground surface through gravity flow. Overall, these technical benefits make the system more efficient and effective at removing liquids such as drilling fluids (mud) collected along underground sewer systems.

Problems solved by technology

Technological Problem: Current methods used for processing contamination deposit pipelines require significant capital expenditure and may result in secondary pollutions due to untreated residue left behind from previous cleanouts. Therefore, there exists a technical solution called environmentally protective dredger (EDD) that combines physical removal and electrical heat abstraction techniques to effectively remove harmful substances while minimizing damage caused by moving objects.
