The Concentration and the Abatement Strategy of Organic Contaminants in Sewage Sludge Dewatering

Abstract

Abstract. Sludge agriculture application in future will be one of the main sewage sludge disposal ways in China. To ensure safety and environment of sewage sludge agriculture application, except to strengthen the research of sludge heavy metal, pathogen outside the organic contaminants will be one of the focuses of the future research, especially to strengthen the PAHs and NP/NPE. In order to reduce the environmental risks of sludge agriculture application, using biological aerobic fermentation processing technology treatment sludge can effectively reduce the organic contaminants, depress secondary pollution problem, which sewage sludge brings.
