高炉瓦斯灰曝气生物滤池填料的制备及其性能研究

以高炉瓦斯灰为主要原料、粘土和硅酸钠作为添加剂制备曝气生物滤池填料.通过正交试验得出高炉瓦斯灰曝气生物滤池填料的最佳制备工艺条件为：高炉瓦斯灰、粘土、硅酸钠质量分数分别为79%，15%，6%，烧制温度为600℃. 该曝气生物滤池填料具有密度较小、强度较大、比表面较大等特点，将其应用于曝气生物滤池处理酱油废水，在水力停留时间为4h、气水比6∶1、滤层高度为100cm的情况下，COD的去除率达到70.3%，NH3-N的去除率达到74%，色度的去除率达到60%，取得了较好的处理效果. 利用高炉瓦斯灰制备曝气生物滤池填料，为高炉瓦斯灰的资源化利用探索了一条新途径.     

Bioscouring Knitted Cotton Fabric with an Experimental Pectate Lyase

An experimental pectate lyase enzyme was used toscour knitted cotton fabric and the emphasis was on pectinremoval. Using an enzyme dosage of 0.2 g/L at temperature55℃ and pH 6.35 for 30 rain, good scouring properties wereobtained. When appropriate concentrations of 1 - HydroxyEthylidene- 1, 1 - Diphosphonic Acid(HEDP) and CaCl2were added, the percentage pectin removal improvedsignificantly.

Impact of dissolved humic acid on the bioavailability of acenaphthene and chrysene assessed by membrane-based passive samplers

Dissolved organic carbon (DOC) is known to reduce the bioavailability of hydrophobic organic compounds (HOCs) in aqueous environments. This reduction occurs as a result of adsorption to DOC, apparently reducing the freely dissolved concentration of HOCs. In the present study, triolein-embedded cellulose acetate membrane (TECAM) and Japanese medaka (Oryzias latipes) were used to measure the uptake of acenaphthene and chrysene in the presence of commercial humic acid (HA) at different concentrations (0―15 mg C·L-1) under controlled laboratory conditions. Apparent uptake rate constants for PAHs in TECAM and medaka were compared and DOC-water partition coefficients (KDOCs) of two PAHs were calculated with different sampling methods by model fit. Results showed that HA present in water significantly reduced the uptake of PAHs in TECAM and medaka. The obtained values of log KDOC of acenaphthene and chrysene measured by TECAM were 4.63 and 5.83, respectively, whereas biologically determined values were 4.52 and 5.76, respectively. These log KDOC values were comparable to earlier published KDOCs toward commercial HA, thereby indicating that TECAM accumulated only the freely dissolved fraction of chemicals and uptake PAHs in a manner similar to that of fish. All these results suggested that the TECAM method can provide a good means for assessing the impact of DOC on bioavailability of PAHs in the aqueous environment.     

苔藓与种子植物对不同化学元素富集能力的比较

采用电感耦合等离子体发射光谱（ICP—ES）对采自浙江省天目山国家自然保护区的18种苔藓和4种种子植物体内的As，Cd，Cr，Cu，Mn，Ni，Pb，V，Zn，A1，Fe，K，Ca，Na，Mg，P16种元素含量进行测定和比较．结果表明：不同苔藓植物对同种元素的富集能力不同，同种苔藓对不同元素的富集能力也不同；部分土生苔藓植物体内及其着生的土壤中的元素含量比较说明：苔藓植物体内重金属含量与其生长基质无显著相关性．同时证明苔藓植物在监测重金属污染方面要优于种子植物，是一种良好的大气质量指示植物．

The mechanism of HIT/DLR prosthetic hand

A multi-sensory five-fingered prosthetic hand has been designed on the basis of underactuated mechanism and coupling principle. The hand is much similar to the adult hand. Three motors actuate the thumb, the index finger and the other three fingers each. The hand comprises 13 joints. Actuated by a motor, the thumb can move along a conic surface, which is superior in appearance. Driven by another motor with springs as transmission elements, the mid finger, ring finger and little finger can envelop objects with complex shape. The sensory system and the appearance design are introduced. It was verified by experiments that the hand has strong capacity of self adaptation and can accomplish accurate and powerful grasp for objects with complex shape.

Zn(Ⅱ)-(NH4)2SO4-H2O体系浸出锌烟尘

提出硫酸铵浸出法处理锌烟尘的新工艺。该工艺利用不同温度下锌在硫酸铵溶液中的溶解度的差别,先在高温下将锌浸入溶液然后降温冷却,使锌呈含F和Cl很低的复盐析出,然后回收。以株冶集团锌烟尘为试料,对浸出过程进行研究。研究结果表明:浸出温度和硫酸铵浓度显著影响锌的浸出率;最佳浸出条件是:液固比为16?1,硫酸铵浓度为4.0 mol/L,pH值为5.5,浸出温度为90℃,浸出时间为4 h,在该条件下,按渣含锌计算的浸出率达到85.16%。
