| 摘 要： | 采用EDTA滴定法以热电厂废弃物粉煤灰为吸附剂,对含镍废水进行了吸附研究,模拟测定了影响粉煤灰吸附工业废水中重金属离子的几种因素。结果表明:低温,高的镍离子浓度,粉煤灰颗粒细、数量多能提高粉煤灰的吸附效能。同时这种方法简便,成本低廉,能达到以废治废的目的。

| Abstract: | The adsorption of coal ash in treating Ni-containing wastewater was studied with EDTA titration, Effects of temperature,wastewater concentration,ash dosage, particle diameter,mixing time and its quantity were examined. The result showed that high concentration of wastewater, low finesse, long mixing time, low temperature and increased quantities can improve tile removal efficiency of coal ash. This method of treatment may get benefit of economy and society and can achieve the purpose of study. |
