摘要：

Methods of handling organic wastes more safely and decreasing the degree of hazard of disposed organic wastes are becoming critical elements in any hazardous waste management planning. In this study the potential of a thermosetting polyester polymer to solidify/stabiIize phenol, a primary constituent in many organic hazardous wastes and with a very low allowable level in drinking water, was investigated. The performance of rapid-setting high-strength polyester polymer in immobilizing 0.5 percent and 2 percent phenol has been studied in detail and compared to that of Type I portland cement. The effect of phenol concentrations on setting and microstructure of the polyester polymer and cement have been investigated. Phenol inhibits the setting of polyester polymer and cement and also produces large voids in the cement matrix. The phenol leachability and compressive and tensile properties were studied with curing time up to 30 days. Most of the polyester polymer solidified phenol specimens showed no measurable amount of phenol in the leachate after the extraction procedure test. The phenol recovery from cement matrix is very much dependent on curing time and initial phenol content. The compressive and tensile strengths of solidified waste reduces with increasing phenol content. The polyester polymer is very effective in rapidly solidifying/stabilizing phenol and the solidified waste has the potential to be used in construction applications. © 1990.
