摘　　要：为研究原位稳定化法修复轻度重金属污染土壤的工程可行性,以某轻度重金属污染的农田土壤为研究对象,开展原位稳定化法修复土壤的中试研究。结果表明,1#固化剂和2#固化剂的修复效果差别不大;固化剂投加量越大,修复效果越好;在一定时间内,投加固化剂后,修复时间越长,修复效果越好。总体而言,在不影响正常生产活动的同时,降低了农田中的重金属含量,原位稳定化修复对于轻度重金属污染农田土壤具有一定的优势。In order to study the engineering feasibility of the in-situ stabilization method for remediation of mild heavy metal contaminated soil,a farmland soil contaminated with a mild heavy metal was taken as a research object to carry out a pilot study of in-situ stabilization method for soil remediation.The results showed that there was little difference between 1#curing agent and 2#curing agent;the greater the dosage,the better the remediate effect;within a certain period of time,after adding the curing agent,the longer the remediate time,the better the remediate effect.Overall,while not affecting the normal production activities,the heavy metal content in the farmland was reduced,and the in-situ stabilization remediation has certain advantages for the mild heavy metal contaminated farmland soil.
