摘要
在分离获得的三株高效脱色菌组成的混合脱色菌种基础上，利用固定化微生物 氧移动床与好氧生物氧化法结合的工艺处理人工配制的偶氮染料废水，在１５－１８℃的条件下，当原水ＣＯＤ浓度为１５００ｍｇ／Ｌ＝１５８０ｍｇ／Ｌ，色度４００倍，厌氧水为停留时间８ｈ，好氧容积负荷率４．０ｋｇＣＯＤ／ｍ＾３（填料），ｄ时，色度及ＣＯＤ的去除率分别为９６．９％及９３．４％。
On the basis of a mixed decolourizing microorganism group that consists of three strains isolated Highly effective Decolourizing Microorganisms(HDM), a new treatment process consisted of an Immobilized Growht Microorganisms(IGM) in Anaerobic Moving Bed (AMB) and an Aerobic Bio-contact Oxidation (ABO) to treat man-made Azo dyes wastewater were studied in this paper. Under the conditions of temperature 15℃～18℃, the influent COD concentration 1500～1580mg/L, colour 400 times, AMB HRT 8h and ABO volumetric loading rates 4. 0kg COD/m3. d, the percentage of removing colour and COD are 96. 9%and 93.4% respectively.
