【摘要】 在对粉煤灰的吸附性能进行分析的基础上,对粉煤灰处理含铅废水进行了试验研究,并对其影响因素进行了探讨,得到了最佳处理条件。试验表明,粉煤灰吸附铅的最佳条件为:时间为12h,灰水比为1∶10,pH值为7.5,温度为30℃。在此处理条件下,粉煤灰对铅的去除率达到94.3%。更多还原

【Abstract】 Base on the analysis of the adsorptive features of fly ash,the paper had a test research on the lead content waste water treatment with fly ash and discussed the influence factors.The optimum treatment conditions were obtained from the test.The test results showed that the optimum conditions to adsorb the lead with fly ash were as followings:The time was 12 hours,the fly ash and waste water ratio was 1∶10,the pH value was 7.5,the temperature was 30℃.Under this treatment condition,the lead removing rate with the fly ash could be reached to 94.3%.更多还原
