采用几种方法对粉煤灰进行湿法改性,并探讨了改性粉煤灰对实验室模拟含铬废水的去除效果。实验结果表明,A1Cl3和FeCl3改性粉煤灰处理5mg/L含铬废水10mL,调节pH值4,投加3g改性粉煤灰,反应90min后,六价铬的去除率可达99%。因此,粉煤灰可以作为一种有效的吸附剂来处理含铬废水。

The fly ash, modified by several methods was used to conduct adsorption treatment experiment, simulating chromium-containing wastewater. The result showed that the removal rate of sixvalent chromium can reach 99% in the treatment of 10 mL wastewater with sixvalent chromium of 5 mg/L concentration under conditions, pH 4, and 3 g of fly ash modified by A1Cl3 and FeCl3 and 90 min of reaction time. So it can be used as a kind of effective adsorbent in chro-mate wastewater treatment.
