Abstract

PURPOSE: To improve the dehydration efficiency of sludge flocs by adding 30W 150pts.wt. powdr coke and 0.5W4pts.wt. a cationic org. high polymer flocculating agent to 100pts.wt. sludge (solids), flocculating flocs and separating the flocs.
CONSTITUTION: 30W150pts.wt. powder coke of 12W100 meshes grain sizes and 0.5W4pts.wt. a cationic org. high polymer flocculating agent based on 100pts.wt. sludge solids are added to sludge such as excess sludge, concd. sludge, highly treated sludge or the like, and the sludge flocs are flocculated and separated. Thence, the separated sludge flocs are dehydrated with a dehydrator, whereby dehydrated cake of low water contents is obtd. It is possible to utilize the coke produced from coke furnace effectively for the utilize the coke produced from coke furnace effectively for the above-mentioned coke. As the dehydrator, a vacuum dehydrator, a centrifugal dehydrator, a belt press dehydrator, and the like are usable for the dehydrator.
