  Abstract

For increase of recycling rate of steel-making slag, the swine wastewater treatment using steel-making slag as filter media were investigated. As the discharged wastewater from the existing facilities retreated through the laboratory wastewater treatment equipment filled with steel-making slag as filter, pH of retreated wastewater was increased, and the concentration of N, P, COD and BOD were decreased. For the pilot experiment, steel-making slag eliminated suspended substances and absorbed a shock of sudden change of their concentration in influent. COD and BOD were decreased under the influence of them in influent. As calcination increased the amount of free-CaO in steel-making slag, the calcined eliminated phosphorus more effectively and increase pH than the uncalcined.
