摘要
Abstract
[ Objective] The aim was to obtain higher COD removal rate so as to guide the process of citric acid industrial wastewater. [ Method] The effects of controllable factors, acidification time, hydraulic retention time, and influent COD concentration, in-anaerobic treatment process of citric acid wastewater on COD removal rate were studied and the COD removal rate was optimized by response surface method. [ Result] There was no interaction between acidification time and the other two factors. It was showed that hydraulic retention time and influent COD concentration had significant effect on COD removal rate and there was interaction between the two factors. The optimum COD removing process conditions was as follows; acidification time 1. 53 h, hydraulic retention time 3. 52 h and influent COD concentration2 698 mg/L. Under the optimized conditions, the COD removal rate was 93. 31% and it was much closed to the experimental result, 93. 29% . [Conclusion] Using response surface method to optimize the anaerobic treatment of citric acid wastewater can result in optimized achievement.关键词
