Development of a DDT Manufacturing and Processing Plant Waste Treatment System.

摘要

The report gives results of a study both to test the feasibility of detoxification of DDT manufacturing wastes,using solvent extraction,and to develop a practical process,if possible. Three different liquid-liquid contacting devices were tested:all provided reasonably good extraction of DDT and homologs from the caustic aqueous phase. Unfortunately,major phase separation problems resulted in excessive losses of monochlorobenzene solvent to the aqueous phase. Efforts to improve coalescence/phase separation were unsuccessful. Further development of a solvent extraction process for detoxification of DDT manufacturing waste cannot be justified.
