The results showed that the optimum conditions for pretreatment of coking wastewater were 6 g activated carbon per liter, 30 ℃, pH=9 and reaction for 20 min, under which the removal efficiency of organic pollutants are more than 70%. Among the 56 kinds of organic compounds, 45 kinds such as dolichoalkanes, polynucleation aromatic series, azacyclo compounds could be removed, and the removal ratios of amidobenzene, hydroxybenzene, indoleacetic, acid-2-methyl-phenyl-ester are 63.5%, 42.6%, 88.1%, 28.1% respectively, while cresol and xylenol are more than 70% and 85%.

结果表明，在最佳反应条件即活性炭投加量6 g·L-1，温度30 ℃，pH＝9，反应时间20 min的情况下处理废水有机物去除率大于70％，原水中检测出的56种有机物中的45种被去除，如长链烷烃、多环芳香族及氮杂环化合物等的浓度降至检测限以下，剩余的11种有机物中苯胺、苯酚、吲哚、乙酸-2-甲基苯酯的去除率分别达到63.5％、42.6％、88.1％、28.1％，甲苯酚和二甲苯酚(5种)去除率在70％和85％以上。

The present business card printing and membership card making business in the widely-used or traditional solvent-based inks, solvent-based inks from paints, solvents, binders, fillers and adjuvant, solvent used mainly aromatic hydrocarbons, esters, ethers, flavoniod etc, these toxic solvent, it finds that, in the packaging of food, medicines, and cosmetics, and so on; and a volatile, with a stronger hen'egg cretonne, will pollute the environment and the health of workers; solventing and imflammable, there is the production of a security risk.

目前制卡和会员卡制作行业中广泛使用的还是传统的溶剂型油墨，溶剂型油墨由颜料、连结料、溶剂、填充剂和辅助剂组成，所用的溶剂主要是芳香烃类、酯类、酮类、醚类等有机溶剂，这些溶剂大都具有毒性，会污染所包装的食品、药物和化妆品等物品；且具有挥发性，有较浓的刺激性气味，会污染环境并影响工人的身体健康；有机溶剂易燃易爆，存在着生产安全隐患。

Aromatic solvent evaporation of volatile is relatively low in calories, fast and dissolubility, while the larger class of toxic solvents; solvents volatile dissolubility good, fast, low cost, but a large cretonne; alcohols in dissolubility, not volatile speed and above two categories, but non-toxic, tasteless, pollution-free.

芳香类溶剂蒸发热量比较低、挥发速度快、溶解性能高，但该类溶剂毒性较大；酯类溶剂溶解性能好、挥发速度快、成本低，但气味比较大；醇类溶剂在溶解性能、挥发速度上都不及以上两类，但是无毒、无味，没有污染。

In the present study, Hartree-Fock and Density Functional Theory with different basis sets were employed to calculate the structural and thermodynamic parameters of 66 thiophenyl, phenyl sulfoxide and phenylsulfonyl cycloalkane carboxylates. With the statistic software SPSS11.5 for windows and GQSARF2.0, the QSAR models relating physicochemical properties of these compounds to their structural and thermodynamic parameters were successfully obtained, using multiple stepwise regression method. The physicochemical properties observed in this work include octanol/water partition coefficient, chromatographic capacity index, toxicity (EC50 and LC50), and solubility etc.

本文采用从头算方法中的Hartree-Fock 方法、密度泛函理论方法(Density functional theory，简称DFT)中的不同基组，计算了苯硫基、苯亚砜基和苯砜基含硫芳香羧酸酯三类共66 个化合物的结构参数和热力学参数，利用SPSS11.5 for windows 统计软件和GQSARF2.0 软件，采用多元逐步回归法拟合得到与溶质-溶剂相互作用有关的物理化学性质与结构参数和热力学参数之间的QSAR 方程，这些物理化学性质包括辛醇/水分配系数、色谱容量因子、毒性(EC50和LC50)、溶解度等。
