METHOD FOR THE REMOVAL OF PHOSPHOROUS IN WASTE WATER USING STEELMAKING SLAG

摘要

The present invention relates to a method of removing wastewater with steel slag , ; is obtained by water-cooling the steel slag basicity (CaO / SiO ₂ ) 4.0 ~ 5.0 , and FeO 10 ~ 15 2 ~ 10 parts by weight in the slag yard toughness minutes containing waste water containing the wt .%% for at least one hour was put into a reaction, comprising the recovery of the slag from the waste water , removal of waste water using a method is provided in the steel-making slag . ; the steel slag according to the present invention the phosphorus contained in waste water can be removed without using a separate lead to sludge or by-products and other without additives , and may be recycled in particular, whereby the slag collected in the original printing .
