摘要
为了解决造纸废水和粉煤灰对环境造成的污染问题。论述了将粉煤灰作为吸附剂直接投加、改性后投加以及与其他工艺联用在造纸废水处理方面的应用情况。结果表明,将粉煤灰用于造纸废水的处理具有工艺简单、效果好、处理费用低等特点,可达到“以废治废”的综合处理目的,具有广阔的应用前景。同时指出了现有工艺中存在的问题,在今后的研究中应进一步加强对粉煤灰处理废水的机理、灰水分离以及饱和灰的最终处置等方面的研究。
In order to solve the environmental pollution caused by paper making wastewater and fly ash, application of fly ash as sorbent, added after modification and combined with other process in the treatment of paper making wastewater was summarized. The results show that application of fly ash in paper making wastewater treatment has the characteristic of simple in process, good effect and lower operation cost. And this process has expansive application foreground. The problems remained were pointed out. Further research on the mechanism of wastewater treatment with fly ash, separation and final utilization of the saturated fly ash are needed to do in the near future.
