| 摘 要： | Converter sludge, a byproduct produced on large amounts in the steel making process, is an important resource that can be utilized effectively. This paper describes an experiment in which converter sludge was tested as an adsorbent for the removal of phosphorus from waste water. It was found that the phosphorus removal depended on the amount of converter sludge added, the pH value and the contact time. Under laboratory conditions when the added sludge was 2. 0mg/100ml, the contact time 4h and the pH value of equalized 4, over 88% of phosphorus was removed; the experimental data on converter sludge adsorption of phosphorus in the water fitted the Freundlich isotherm model. Converter sludge was found to be very effective in adsorbing the phosphorus.
