METHOD FOR REMOVING PHOSPHATE IN WASTE WATER USING FOAMED LIGHTWEIGHT CONCRETE MADE BY FROTHING

摘要

PURPOSE: a kind of sludge for being set to dampen generation using foaming lightweight concrete of removal phosphate in waste water passes through fixed the superior's water permeable ability library foaming lightweight concrete. ;CONSTITUTION: slurry has been made after mainly mixing in waste concrete sludge, cold and hot reconciliation water, high efficiency water reducing agent. Calcium hydroxide, anhydrous gypsum, ordinary cement, high alumina cement are added in slurry. Air introduces the slurries, realizes in the second mixed process. The slurry and air inject and solidify 20 degree Celsius 4. A kind of steam curing process realization. A kind of autoclave curing process is implemented. Cooling realization is by just reducing pressure naturally. ;The 2011 of copyright KIPO submissions
