The results showed that: three major peaks,humuslike fluorescence peak A,proteinlike fluorescence peaks B and C appeared on the threedimensional fluorescence spectroscopy;the DOM fluorescence intensity was well related with DOC and CODMn,indicating that fluorescence dissolved organic matter content can reflect both the organic carbon content and the organic matter content by oxidation in the water in August,during the nonalgae bloom outbreak period,fluorescence intensity had a poor correlation with chlorophyll a,indicating that phytoplankton was not the main source of the fluorescent substances.

结果显示:小江回水区DOM的三维荧光光谱主要表现出3个峰,类腐殖质荧光峰A、类蛋白荧光峰B和C;DOM荧光强度与DOC、CODMn相关性较好,表明荧光溶解有机物质的含量可以较好反映水体中有机碳和可被氧化有机物的含量;在8月份非水华暴发时期荧光强度和叶绿素a相关性较差,表明DOM荧光物质主要不是由浮游植物产生。

Shanghai Institute of Applied Physics,Chinese Academy of Sciences,Shanghai 201800Abstract Dyeing wastewater is dificult to be treated mainly for its high chemistry oxygen depleted and higlI chroma ticity.In this paper,a combined hydrol~ic Acidification- Memb rane Bioreaetor processes was employed and the treatment behaviors of reactive dye wastewater were investigated.

Under the influence of the sunlight and with the help of its strong oxidization capacity, the photo-catalyst can oxidize nearly all the organic matters on the surface into H 2 O and the corresponding nontoxic inorganic materials. At the same time, under the combined actions of the characteristic nanometer structure of its surface, the hydroscopic properties of the complex additives and the light-induced amphiphilic properties (hydrophilicity and lipophilicity) of Ti02 itself the surface of the glass is made superhydrophilic, so that it becomes easily washable, anti-fog and not vulnerable to recontamination to keep the glass clean and transparent. And it also has such functions as sanitization, sterilization, foreign odor elimination and air refreshing.

在阳光的作用下,光催化剂以其特有的强氧化能力,可将其表面的几乎所有有机物完全氧化为H 20及相应的无害无机物,同时在其表面特有的纳米结构、复合添加剂的吸水性和Ti02本身的光致两亲性的共同作用下使玻璃表面具有超亲水性,变得易清洗、防雾和不易被再污染而保持洁净透明,同时具有消毒、杀菌、消除异味、清新空气等功能。

It is the inoculable sludge, the peculiarity of wastewater and the framework configuration of the ABR that cause the predominant growth of acidogenic bacteria.(2) The complex containment was gradually removed by sort in the ABR, which showed the ABR has typical characteristics of the plug flow system. Along with the raising of the OLR, The gas yield and rate increase at the same time. The distribution of the gas yield and rate in the ABR is normal school along the way.

对ABR沿程的COD、VFA以及pH的变化规律进行分析,结果表明ABR对有机物的降解过程具有典型的推流系统特征,复杂污染物是以分类逐级的形式得以去除的;污染物的去除主要发生在1~3格室(COD去除贡献为50~80%),随有机负荷的提高,去除主体逐渐后移;系统产气量及沼气产率均随有机负荷的提高而增加;处理红霉素废水时,格室产气量及产气率沿程呈正态分布,分析认为,这是由ABR的特性及废水本身的特点综合作用的结果。
