Method for solidifying heavy metals in waste incineration slag
The invention relates to the technical field of solid waste environmental protection, in particular to a method for solidifying heavy metals in waste incineration slag. The method comprises the steps of smashing, eddy current sorting, curing and maintaining. After slag is smashed, heavy metal powder is screened out through an eddy current sorting machine, and then heavy metal can be effectively adsorbed through a molecular sieve curing agent; and under the action of water and an alkali activator, the curing agent can effectively adhere to and fix the heavy metal powder, and then cured heavy metal can be obtained through curing. Only a very small amount of metal is leached after the heavy metal fixed by the curing method is placed for one year.
本发明涉及固废环保技术领域，具体涉及一种垃圾焚烧炉渣重金属固化方法，包括粉碎、涡电流分选、固化、养护几个步骤，炉渣粉碎后通过涡电流分选机筛选出重金属粉末，然后通过分子筛固化剂能够有效吸附重金属，再加上水和碱激发剂的作用，使得固化剂能够有效粘附、固定重金属粉末，然后经养护即可得到被固化的重金属。该固化方法固定的重金属放置一年只有极少量的金属浸出。
