染料生物吸附影响因素与解吸条件研究

用筛选出的一株丝状真菌(GX2)对活性、酸性、碱性和直接染料进行吸附及解吸的试验结果表明，该菌株对活性、酸性和直接染料有较高的吸附率，但碱性染料难被吸附；在多种有机溶剂中，丙酮是较好的解吸剂，碱性介质有利于染料的解吸；对菌体进行破碎及在解吸过程中加以搅拌有利于解吸过程的进行。     

黄磷尾气现场脱硫试验

黄磷尾气的主要成分是CO，其中含硫杂质主要以硫化氢的形式存在。测定了黄磷尾气中硫化氢、氧气的含量，分别采用吸收、吸附工艺及其组合工艺对黄磷尾气进行了现场脱硫试验，得出了最佳的黄磷尾气净化脱硫工艺，即吸收、活性炭变温吸附。出口气中H2s的质量浓度为1—5mg/m^3，净化效率达到99．7％。

The Relation Between Sandstorms and Strong Winds in Xinjiang,China

With observational data spanning 1961–1999 from 90 meteorological stations in Xinjiang, China, the spatial and temporal characteristics of sandstorms and strong winds, and the contribution of strong winds to the occurrence of sandstormsare analyzed. Moreover, the dominant wind direction and minimumwind speeds during sandstorm periods are discussed. The research shows that although possessing similar climatic trends, sandstorms and strong winds in Xinjiang have opposite geographical distributions, i.e. places with more sandstorms show fewer strong winds. The contribution of strongwinds to sandstorms in northern Xinjiang is larger than that insouthern Xinjiang. The dominant wind directions clearly indicatethe paths of the weather systems that introduced the sandstorms.The minimum wind speeds in the sandstorms were over 10 ms^-1in northern and eastern Xinjiang and in the Turpan and Yanqi Basins of southern Xinjiang. In Tarim Basin of southern Xinjiang,however, the minimum wind speed was about 6–8 ms^-1, and even 6 ms^-1 at its southern edge.

洗涤法处理含油土壤的研究

研究了用洗涤法处理含油土壤，考察了洗涤剂种类与浓度、洗涤温度、液固比、洗涤时间、表面活性剂、洗涤液直接循环使用次数对洗涤效果的影响，结果表明：当混合减浓度为10000mg／L、洗涤温度为70℃、液固比2：1、洗涤时间20min时，可将含油量为30％的土壤洗至残油率仅为0．3％左右。OP、EL型表面活性剂的加入对洗涤效果没有改善，特别有意义的是洗涤液能够直接循环使用而对洗涤效果基本无影响，这不仅能够减少用水量，还可以大大减少废水的排放量，降低操作费用及废水处理费用。该洗涤法不涉及物质的相变过程，混合碱由廉价的无机碱和无机盐组成，故能量消耗低，处理费用也低，且洗脱下来的原油可回收。
