Emergency drinking water treatment in source water pollution incident—technology and practice in China

An investigation into emergency potable water treatment technologies was conducted to investigate China’s water pollution situation.In order to confirm optimum parameters,the technological efficiency of each pollutant was obtained.About 100 contaminants were tested to find the emergency treatment technologies,most of which were found to be positive.This paper presents the three largest and most significant water pollution incidents in China to date,analyzing cases such as the nitrobenzene pollution incident in the Songhua River in November 2005,the cadmium pollution incident in the Beijiang River in December 2005,and the water crisis with odorous tap water in Wuxi City in May 2007.
