Biological degradation of a comples waste associated with the manufacture of herbicides, specifically 2, 4-D, 2, 4, 5-T, and 2, 4, 5-TP acids, was accomplished under actual field conditions. A completely stirred aeration lagoon was installed between an existing conventional sewage treatment plant and existing stabilization lagoons to avoid hydraulic overloading of the former and reduce the BOD loading to the latter. Joint treatment of the herbicide waste and diluting municipal wastes was accomplished biologically, demonstrating that pilot plant studies related to such wastes reported in other literature are valid. In vitro experiments with individual chlorophenols and the related chlorophenoxy acids diluted with aeration lagoon effluent indicated that these substances are rapidly decomposed when sufficient biological populations have been established.
