【摘要】 通过实验,研究了影响DAT-IAT工艺处理生活污水性能的主要因素。实验结果表明:进水COD浓度与COD平均去除速率近似于正比关系(进水COD在1130-700 mg/L时);COD去除率随IAT反应时间的延长而增加;DAT连续曝气能有效防止进水污染出水,提高系统去除效果,而且使DAT-IAT工艺具有处理高浓度有机工业废水的潜力。更多还原

【Abstract】 The main factors that affects domestic sewage treatment of DAT- IAT process were researched through experiment. The results indicate that: average COD removal rate is approximately proportional to inflow COD (when inflow COD is between 100 mg/L and 700 mg/L); COD removal percent is on the rise with the prolonging of the IAT reaction time; continuous aeration of DAT can efficiendy protect inflow water polluting outflow water, in turn improve the removal effect,and enable DAT - IAT process to treat high - concentration organic trade effluent potentially.更多还原
