Solidification and stabilization method for chemical waste liquid treatment ash
The invention discloses a curing and stabilizing method for chemical waste liquid disposal ash, which comprises the following steps: mixing a heavy metal curing agent in the chemical waste liquid disposal ash to be treated, and curing by using cement to obtain a cured landfill block; wherein the heavy metal curing agent is any one or a combination of any two or more of calcium oxide, sodium sulfide, sodium dihydrogen phosphate and potassium dihydrogen phosphate. The heavy metal curing agent is added to stabilize and cure excessive heavy metals contained in the chemical waste liquid treatment ash, the used heavy metal curing agent is a common agent, raw materials are easy to obtain and low in cost, meanwhile, a small amount of cement is matched for use, and the stabilization effect of a cured body is good. The method has the characteristics of safety, high efficiency and economy, and is easy to apply and popularize.
本发明公开了一种化工废液处置灰的固化稳定化方法，该固化稳定化方法包括在待处理化工废液处置灰中混合重金属固化剂，再经水泥固化处理得到固化填埋块；其中，重金属固化剂为氧化钙、硫化钠、磷酸二氢钠和磷酸二氢钾中任意一种或任意两种以上组合。本发明通过添加重金属固化剂稳定固化化工废液处置灰中所含有的超标重金属，所使用的重金属固化剂为普通药剂，原料易得，成本低，同时配合少量水泥使用，固化体稳定效果好。本发明具有安全、高效、经济的特点，易于应用推广。
