Solidification/Stabilization Remediation of Acid Organic Waste for Impoundment Units Closure

摘要：

　　Solidification/Stabilization(S/S)with binders is an established remedial approach to reduce the mobility of organic and inorganic contaminants and simultaneously improve the geotechnical properties of soils,sediments and a variety of waste materials.This paper presents the results of a design treatability testing program for the S/S treatment of acid organic waste associated with the remediation and closure of four waste impoundment units at a former chemical manufacturing facility.S/S was selected as the most appropriate technique to improve the compressive strength and reduce the permeability of the waste and reduce the leachability of a complex suite of organic constituents of concern.A variety of mix design formulations were evaluated to implement a two-step treatment process consisting of a neutralization treatment of the acidic waste,followed by S/S treatment.
