为解决煤化工浓盐水零排放及综合利用问题,以煤炭气化灰渣和工业锅炉粉煤灰作为原料,并掺加不同量的煤化工浓盐水,开展了利用充填开采技术对浓盐水进行固化处置实验研究。综合考虑对浓盐水的消纳能力和处置成本,利用充填开采固化处置煤化工浓盐水在技术上是可行的。
In order to solve the problem of zero discharge and comprehensive utilization of concentrated brine in coal chemical industry, coal gasification ash and industrial boiler fly ash were used as raw materials, and different concentrations of coal chemical brine were blended to carry out solidification of brine by using filling and mining technology Disposal experiment study. Taking into account the ability to dispose of concentrated brine and disposal costs, it is technically feasible to use filling mining and solidification to process concentrated brine of coal chemical industry.
