    • PURPOSE:To subject sludge to dewatering treatment by a method in which sludge is packed into an air-tight plastic bag having a filtering material, while the bag is pressed by means of water head, and water filtered through the filtering material from the sludge is discharged. CONSTITUTION:A valve 6 is opened, and as soon as muddy water is started to pack into a water-permeable sheet 4 through a suction pump pipe 10 on the barge side, water in a steel pipe 1 is drained by a water pump 11 on the steel pipe side. By this, muddy water in the barge 9 is packed into the water-permeable sheet 4. After the packing of the muddy water, the level of water in the steel pipe 1 is lowered by DELTAh from the sea surface by operating the water pump 11, whereupon the muddy water packed in the sheet 4 is gradually dewatered under a compressive force corresponding to the head DELTAh.
    • 目的:通过将污泥装入具有过滤材料的气密性塑料袋中的方法使污泥进行脱水处理,同时通过水头压制袋子,通过过滤材料从污泥中过滤的水是 出院。 构成:阀6打开,一旦泥浆水开始通过驳船侧的抽吸泵管10装入透水性片材4中,钢管1中的水就被水泵11排出 钢管一侧。 由此,驳船9中的泥水被包装在透水性片材4中。在泥浆水的包装之后,通过操作水泵11使钢管1中的水位从海面降低DELTA 由此,填充在片材4中的泥浆水在与头部DELTA相对应的压缩力下逐渐脱水。
