摘要：

The purpose of the paper is purifying phosphorus by column experiment and researching phosphorus removal theory of substrates including steel slag, natural sand and limestone. The winch is composed of the following main parts: experiment method and procedure, results and discussion and conclusion. The results indicated: Pure steel slag is not suitable as filling in wastewater land treating. Mixxing natural sands as permeable medium and limestone as Ca resource is essential. The adsorption of steel slag is primary mechanism in purifing phosphorus in mixed column. The ratio of 20% steel slag, 50% natural sand and 30% lime stone is suitable for removing phosphorus in living waste water. The P concentration of effluent was lower than 0.5mg/L.
