Research on Contribution of Phosphate-based Detergent to Municipal Sewage in Beijing

Abstract： Based on the latest study of phosphate detergent ban and restrict, the phosphorus discharge from detergent in Beijing has been investigated. According to the status of wastewater treatment plants and its practical function, phosphate-based detergent's contribution to the municipal sewage is calculated to be 8.41%, which is less than the average (20% ) in most other cities of China. 作 者： HE Xu-wen    WANG Dian-fang    ZHANG Xian    YU Jun-jie    LIU Hai-tao   作者單位： HE Xu-wen(Beijing University of Sciences and Technology, Beijing 100083, China;School of Chemical and Environmental Engineering, CUMT, Beijing 100083, China)
