累托石处理铜冶炼工业废水研究

Study on Treatment of Cu(Ⅱ)-containing Copper Smelter Wastewater with Rectorite

研究了以累托石为吸附剂对含Cu(Ⅱ)的铜冶炼工业废水进行处理。实验结果表明,在不调节铜冶炼废水pH值的条件下,累托石用量为0.03g/ml,作用时间为30min,温度为25℃,Cu(Ⅱ)的去除率可达96.70%,处理后水质符合国家污水综合排放标准(GB8978-1996)中的一级指标。

In this paper, the Cu （ Ⅱ ）-containing copper smelter wastewater heated with rectorite as adsorbent has been studied. The experimental results show that under the conditions without adjusting the pH, with the amount of the rectorite of 0.03g/ml, the reaction time of 30 minutes, and the temperature of 25℃ ,the efficiency for rectorite to remove Cu （Ⅱ） from copper smelter wastewater is 96.70%, and the quality indexes of the wsstewater after treatment conform with the national discharge standard.
