Waste incineration fly ash heavy metal chelating agent and application method thereof

The invention discloses a waste incineration fly ash heavy metal chelating agent and an application method thereof. The waste incineration fly ash heavy metal chelating agent comprises the following raw materials in percentage by mass: 35-40% of potassium fulvate and 10% of a dithio compound. 0.2% of an ampholytic surfactant and the balance of water. The heavy metal chelating agent is mainly used for treating heavy metal ions contained in the incineration waste fly ash, the heavy metal ions in the incineration waste fly ash can be rapidly and stably chelated, the chelating rate reaches 98% or above, secondary pollution is not prone to being generated, the preparation process is simple, non-toxic, efficient, low in cost and suitable for large-scale production, and the method has a wide application prospect. Good application prospects and market prospects are realized. 本发明公开了一种垃圾焚烧飞灰重金属螯合剂及其应用方法，其中垃圾焚烧飞灰重金属螯合剂的原料按质量百分比包括：黄腐酸钾35～40％，二硫代化合物10％；两性表面活性剂0.2％，余量为水。本发明中的重金属螯合剂主要用于焚烧垃圾飞灰中含有的重金属离子处理，可快速将焚烧垃圾飞灰中重金属离子稳定螯合
