| 摘 要： | 以受污染河道的黑臭水体为研究对象,比较了三种曝气方式(低强度连续曝气、间歇曝气和高强度连续曝气)对水体的修复效果,分析了低强度曝气技术的可行性.结果表明,对于流量较小的缓速滞流河道,长期采用低强度曝气可达到降低污染负荷、消除水体黑臭的效果;以氨氪去除率达98%为控制指标,低强度曝气能耗仅为高强度连续曝气的6.25%和间歇曝气的17.24%,大大降低了曝气经济成本.

| Abstract: | Taking the black-odor water from polluted river as object,the effect of three aeration modes including low-intensity continuous aeration,intermittent aeration and high-intensity continuous aeration on the remediation of the water body was compared,and the feasibility of low-intensity aeration was analyzed.The study results show that for black-odor river with small and slow flow rate,the long-term low-intensity aeration can reduce pollution load and eliminate black-odor.Taking the NH3-N removal efficiency of... |
