摘要：
研究了以粉煤灰为吸附剂处理含砷工业废水。实验结果表明,在不调节含砷工业废水pH的条件下,粉煤灰投加质量浓度为0.05g/mL,吸附时间为60min,温度为25℃,砷的去除率达87.0%,处理后的水符合GB8978—1996污水综合排放标准。该工艺简单,以废治废,成本低廉,具有良好的应用前景。

Abstract:
The arsenic-containing industrial wastewater treated with fly ash as adsorbent has been studied.The experimental results show that under the conditions without adjusting the pH, with the amount of the fly ash of 0.05 g/mL, the reaction time of 60 min, and the temperature of 25 ℃, the efficiency for fly ash to remove arsenic from industrial wastewater is 87.0%, and the quality indexes of the wastewater after treatment conform with the integrated wastewater discharge standard(GB8978—1996). The technique is simple,the wastewater is harnessed by other waste, and the cost is lower. Therefore, it will have better applied prospect.
