Abstract

PURPOSE: To improve flocculating effect and dehydrating effect of a treating agent obtained by mixing fibrous materials and nonself-setting cement for waste water, sludge, etc. and make it inexpensive.
CONSTITUTION: This treating agent is prepd. by mixing the cement which is made nonself setting by adding a large amount of water to fibrous materials such as waste pulp and scrap paper and allowing sufficient hydration to take place and the nonself-setting cement such as the cement-contg. solid materials obtained by subjecting the waste water discharged from cement product producing processes to solid-liquid separating treatment. If waste water is treated with this treating agent, the COD in the waste water is decreased by the Al, Mg, Ca, etc. in the nonself-setting cement, and the settling speed of polluting materials is increased. If this is added into sludge, excessive compacting during dehydration is prevented and dehydration efficiency is improved.
