摘　　要：以印染废水为主的城镇废水中含有大量难降解有机物,可生化性较差。为提高该类废水的可生化性,采用HUSB反应器对环太湖城镇的实际混合工业废水进行预处理,通过紫外-可见光光谱、GC-MS等手段对废水中的有机组分在处理前后的变化进行表征,评价了废水可生化性的差异。结果显示,废水B/C值从0.251提升至0.423,废水中部分大分子有机物分解为小分子有机物,含有不饱和键的芳香类及环烃化合物含量有所下降,说明该类废水经过HUSB反应器处理后可生化性得到了显著提高。Municipal wastewater that consists mainly of dyeing and printing wastewater contains a large quantity of refractory organics,and is hard for biological treatment.To improve the biodegradability of this mixed industry wastewater,the HUSB reactor was studied as a pretreatment technology for mixed practical industrial wastewater in the Tai Lake basin.Ultraviolet-visible spectrophotometry,GC-MS,etc.,were utilized to identify the change of the biodegradation of organic pollutants and evaluate the biodegradability of the wastewater after treatment.The results show that the biodegradability of these wastewater is enhanced greatly by HUSB reactor： the value of B/C is raised from 0.251 to 0.423;part of the large molecule organics in the wastewater are broken to small molecule organics;the contents of the unsaturated aromatic compounds and hydrocarbons decrease after the pretreatment by HUSB reactor.
