含纤维素废水生物水解的应用研究

提取植物或动物纤维所产生的高浓有机废水，含短小纤维、木质素、纤维素、半纤维素、蜡质、果胶及其分解产物(糖、脂肪酸、醇等)，较难生物处理，属含纤维素废水。试验研究和生产应用表明，生物水解对含纤维素废水中高分子有机物，可予分解并提高度水可生化性：在常温、PH约9．5时，水解池污泥浓度达6．5～16．0g/L，容积负荷达2．9kgCOD／m^3．d，COD去除率为24—36％，VFA提高3．9—5．1倍，BOD／COD提高12～16％。分析认为：中温、酸性，纤维素、木素含量低时，水解效果应更好。

Production of laccase by Coriolus versicolor and its application in decolorization of dyestuffs: (Ⅱ) Decolorization of dyes by laccase containing fermentation broth with or without self-immobilized mycelia

The capability of decolorization for commercial dyes by Coriolus versicolur fermentation broth containing laccase with or without immobilized mycelium was evaluated.With cell-free fermentation broth containing laccase,high decolorization ratio was achieved for acid orange 7,but not for the other dyes concerned.The immobilized mycelium was proved to be more efficient than the cell-free system.All the four dyestuffs studied were found being decolourized with certain extent by immobilized mycelium.The repeated-batch decolorization was carried out with satisfactory results.The experimental data showed that the continuous decolorization of wastewater from a printing and dyeing industry was possible by using self-immobilized C.Versicolor.     

The effect of heating temperature of thin film transistor-liquid crystal display (TFT-LCD) optical waste glass as a partial substitute partial for clay in eco-brick

In order to fulfill the current WEEE directives, the traditional approach to manage thin film transistor-liquid crystal display (TFT-LCD) waste glass is inadequate. It is a serious opportunity to achieve resource conservation, reduction, stabilization and safety of management of TFT-LCD in the near future. To assist in achieving these goals, this study investigated the sintering characteristics and material properties of TFT-LCD waste glass, which can be pulverized and ground and subsequently blended with clay, at various substitution levels (0–40%) and finally fired from 800 °C to 1000 °C to make eco-brick. The brick thus produced was analyzed to determine variations in weight losses on ignition, 24-h absorption, bulk density, shrinkage, compressive strength and microstructure changes. The results for specific gravity, water adsorption, and compressive strength revealed that bricks made from mixtures containing TFT-LCD waste glass met the general requirements for bricks. The advantages of less water absorption, less weight loss on ignition, and a gain in compressive strength in the clay-TFT-LCD waste glass bricks should encourage the use of TFT-LCD waste glass as a brick additive.

泔脚与秸杆混合发酵法生产蛋白饲料的新工艺流程

利用多菌种混合发酵同时处理泔脚和秸杆2种废弃物,提出了一种生产高蛋白饲料的新工艺流程,并且对该流程初步进行了经济估算。结果表明,在泔脚和稻草秸杆粉按3:1、温度150℃、高压锅中高温湿热酸处理的条件下,经过初步双菌混合发酵试验所得的饲料产品质量为粗蛋白≥25％,粗纤维≤18％,水分≤ 10％,说明新工艺能很好地同时处理泔脚和秸杆2种废弃物,并且大大地提高了秸秆饲料的蛋白含量。处理新工艺流程简单、技术可行,是一种很好的饲料制备方法。     

汞在鲤鱼组织中的蓄积、排出与血流速度的关系

本试验在10±1℃、不喂食条件下测定鲤鱼在30天受汞毒期间鳃、脑和肝胰脏蓄积汞和尾鳍微血管血流速度及30天解毒期间排出汞和血流速度的变化。试验结果:受毒期间鳃中汞的蓄积量最多,解毒期间鳃中汞的排出速度最快;受毒期间血流速度随受毒时间的延长而减慢,又随试验浓度的增高而减慢,解毒期间血流速度随解毒时间的延长而加快;受毒期间高浓度试验组鱼鳃、脑和肝胰脏中汞的蓄积量与血流速度呈负相关,解毒期间鱼鳃中汞的排出量与血流速度呈正相关,汞的浓度与血流速度呈负相关。
