| 摘 要： | 对鼓气曝气和抽气曝气两类曝气方法做了对比研究,结果显示:抽气曝气,稀释水DO始终达不到8mg/L,开放静置24h,DO几乎不增加;鼓气曝气30min,稀释水DO已稳定超过8mg/L,鼓气曝气120min后开放静置20h,DO仍有8mg/L。本文认为,一般情况下,BOD5稀释水曝气只能采用鼓气曝气法;在排量≥100L/min,水量≤20L条件下,曝气120min后,24h内,稀释水DO可满足技术要求。

| Abstract: | Two methods of blower-aeration and vacuum pump-aeratin were comparatively studied. With vacuum pump-aeratin, DO of diluted water can not approach to 8mg/L all the time and increases hardly in 24h open and quiet next .With blower-aeration, DO of diluted water exceedes 8mg/L after 30 min and keep 8mg/L over in 24h open and quiet next after 120 min. Blower-aeration is the only method for aeration of diluted water. 120min is sufficient for blower-aeration and diluted water can be used in 24h. |
