Co-Treatment of Manufactured Gas Plant Site Groundwaters with Municipal Wastewaters. Final Topical Report June 1987-August 1988

摘要

A pilot-scale treatability study was performed to evaluate the capability to effectively treat Manufactured Gas Plant (MGP) site waters using activated sludge biological treatment. The study assessed the effect of co-treatment of MGP site waters on conventional activated sludge treatment system operations. Purgeable aromatics, phenolics, metals, and polynuclear aromatic hydrocarbons were the chemicals-of-interest for three environmental fate mechanisms: volatilization, adsorption, and biodegradation. The results support that the addition of MGP site groundwaters into municipal wastewater streams will result in nonmeasurable effects in terms of activated sludge treatment performance, and nonsignificant effects in terms of treated discharge quality.
