Abstract
According to the fluorine-containing wastewater of source and composition of one ammonium phosphate company, the article combined with analysis of raw sewage treatment technology and comprehensive cost of material by using compound method of lime sulfuric acid on fluorine-containing wastewater. After the precipitation for 20 hours, the measured concentration of fluorine in clear water ＜8 mg/L, and 200 hours＜4 mg/L, with the minimum concentration less than 2.3 mg/L. Thus, this method can effectively reduce the concentration of fluorine in discharged wastewater to emission standard with simple procedure and easy operation. Material is easy to get at low price and no organic matter is added in the process, which avoid secondary pollution and the rise of COD and BOD. But the defect is the existence of a great amount of sludge emissions,which is solved efficiently by the combined method of tailings difficult to collect and cumulate in the company.关键词
