摘要
氧化沟循环比的大小对氧化沟断面大小有很大影响。氧化沟循环比主要取决于曝气充氧的需要和进水水质,曝气充氧对循环比的要求可通过计算确定;进水水质对氧化沟水流混合程度的要求不一样,影响氧化沟循环比。在提高氧化沟循环比的同时,应使氧化沟在一定程度上保留推流式反应器的特点。在设计中对氧化沟的循环比要足够重视。
Circulation ratio of oxidation ditch has an important effect on the size of section in oxidation ditch, and it mainly depends on oxygen demand and influent quality. Circulation ratio depending on oxygen demand can be calculated. Influent quality has an effect on circulation ratio because of the difference of mixing level requested. Oxidation ditch should keep the feature of PF reactor to an extent as increasing circulation ratio. Therefore, circulation ratio of oxidation ditch should be determined according to many factors.
