摘要
由于社会经济的快速发展和工业化的提高,水环境污染越来越严重。本文通过在电热厂实地取样粉煤灰,并用改性前后的粉煤灰分别处理两组不同的废水,用化学的方法测定各组废水处理前后的COD含量,并作比较。实验结果表明,粉煤灰的改性对处理废水环节有很大的效果提升,对粉煤灰改性的研制为废水处理环节提供了更加高效环保的途径,起到了保护环境的作用。
Due to the rapid socio-economic development and industrialization,increased water pollution is getting worse.The project＂Wastewater with Modified Fly Ash and determination of its COD＂is for wastewater treatment before and after the effect of fly ash modified an inquiry contrast experiment.By the electric field sampling plant fly ash and fly ash were modified after two different wastewater treatment,COD content was measured before and after each set of chemical wastewater treatment methods,and for comparison,the experimental results show that the pulverized coal modification of gray wastewater treatment areas have great effect to improve.To carry out this task proved to develop modified fly ash provides a more efficient and environmentally friendly way for wastewater treatment sectors,played a role in protecting the environment.
