摘要
采用厌氧－好氧工艺处理一种染料工业废水，在进水ＣＯＤ为１２００ｍｇ／Ｌ，色度为５００倍时，厌氧段有机负荷（ＣＯＤ）小于５．３ｋｇ／（ｍ￣３·ｄ），水力停留时间６～１０ｈ，好氧段水力停留时间６．５ｈ的条件下，出水ＣＯＤ＜２００ｍｇ／Ｌ，色度＜５０倍，达到了排放标准。同时，还着重讨论了厌氧段在去除ＣＯＤ、色度以及提高废水在好氧条件下的可生化性方面的独特作用。
In this paper,an anaerobic-oxic system for treating dyeing wastewater was studied.When influent COD was 1200 mg/L and color was 500(dilution factor),organic loading ofanaerobic process was less than 5.3 kg COD/(m￣3·d),HRT was 6-10 hour; and aerobic HRTwas 6.5 hour,the effluent COD was less than 200 mg/L,color less than 50,which could meetthe Standard.The function of anerobic process on anaerobic-oxic system was mainly discussed,that is the function of removal of COD and color,and improvment of treatability of the wastewa-ter in aerobic condition.
