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.

The invention provides an ionic liquid dehumidifying method and an ionic liquid dehumidifying system for regulating gas humidity. The ionic liquid dehumidifying method comprises the following steps: enabling gas with higher humidity to sufficiently contact with a gas dehumidifying agent barren liquor, thus at least enabling moisture in the gas to be absorbed by the gas dehumidifying agent barren liquor to obtain a gas with lower humidity and a gas dehumidifying agent rich liquor; the gas dehumidifying agent barren liquor contains ionic liquor at least capable of absorbing water. Preferably, ionic liquid is adopted as the gas dehumidifying agent barren liquor. Preferably, the ionic liquid can also absorb volatile organic compounds. Water in the gas can be efficiently and fast removed by adopting the ionic liquid as a dehumidifying agent, the needed equipment is simple, and the system can stably and reliably run, and is safe and environment-friendly. The ionic liquid dehumidifying method and system are especially applicable to manufacturing shops needing to control air humidity, such as lithium battery, medicament manufacturing shops, and dried warehouses; and also, the ionic liquid dehumidifying method and system can also be applied to dewatering and purification technology of natural gas, associated gas and the like.

The invention relates to a hydraulic geotextile bag dewatering box. A water seepage tank is formed among platform brackets or separator plates arranged on the bottom layer of the dewatering box; a dewatering bag is flat laid on the platform brackets or the separator plates; a hydraulic bag is flat laid on the dewatering bag; a mud injection opening is formed in the dewatering bag; a water inlet is formed in the hydraulic bag; a water outlet is formed in the water seepage tank; the water inlet of the hydraulic bag is connected with the water outlet of the water seepage tank through a pipe and a water pump. The dewatering box can complete the dewatering process on the water desilting site, and can effectively solve the transport and subsequent disposal problems caused by high moisture content of sludge. According to the invention, the dewatering effect of the geotextile bag is strengthened by using the dewatering box body and the hydraulic function, and the equipment structure and dewatering process are described; the method and equipment can effectively improve the dewatering efficiency of the geotextile bag, reduce the operation time, effectively improve the quality of separated water, and reduce the secondary pollution; the equipment can also be used for dewatering sewage sludge, building mud, bean dregs and other materials.

The invention relates to a preparation method of medicinal active carbon. The dried bagasse is used as raw materials, and is crushed; then, the materials are added into a potassium carbonate solution to be soaked; the weight ratio of the bagasse to the potassium carbonate solution is 1:(4 to 7); the soaked bagasse is subjected to centrifugation dewatering; then, air isolation is performed for carbonization treatment; carbides are obtained; the carbides are subjected to acid washing by hydrochloric acid, and are then washed by water to a neutral state; finally, drying and sieving are performed. The medicinal active carbon has the advantages that the decoloring speed is high; the adsorption capability is high; the medical property of the medicine per se is not influenced.
