Concentration and characteristics of trihalomethane precurosrs in raw and treated livestock manure

摘要

To reduce the diffusion of trihalomethane precursors from livestock farm, field survey and laboratory experiments were carried out concerning 1) trihalomethane precursors concentra- tion in livestock barn wastewater and effluent of treatment facilities, 2) potential diffusion of trihalomethane precursors from manure and compost, and 3) fate of trihalomethane precursors from composted manure in soil and aquatic environments. Median value of trihalomethane formation potential (THMFP) in wastewater from 11 livestock barn was 7,700μg.l~-1.
