采用镁系固化剂 (MI 固化剂) 对污泥进行固化预处理,对预处理后的污泥的物理性质、水力学性质和土力学性质以及重金属存在形态等进行监测,同时通过现场试验和监测确定未经填埋的固化污泥是否达到资源化利用的标准,是否具有制作回填土及营养土的可能性.%The Mg-curing agent (Ml curing agent) was applied to sludge solidification pretreatment. The physical properties, hydrodynamic properties, soil mechanical properties and existing form of heavy metals of pretreated sludge were monitored. It is ascertained that whether the solidified sludge can meet the utilization standards and the possibility of manufacturing backfill and nutrition soil with sludge by field experiments and monitoring.
