膜分离技术处理电镀废水的实验研究

采用纳滤＋反渗透2级处理系统浓缩回收电镀铜漂洗废水。实验结果显示：在△P=1．5MPa条件下进行浓缩．纳滤膜可以使料液浓缩近10倍。纳滤膜对Cu^2＋的截留率在96％以上，对COD的截留率在57％以上。在△P=3．0MPa条件下进行浓缩，反渗透膜可以使料液浓缩近10倍。反渗透膜对Cu^2＋的截留率在98％以上，对COD的截留率在67％以上。随着料液浓度的增加，纳滤膜和反渗透膜的截留率会降低。     

建立能够体现化工行业特点的行业排放标准初探

化工行业具有传统的工业类型和新兴产业交叉渗透的特点。现有的污染物排放标准因涵盖行业过多、细化内容不够、可操作性不强、行业特点不突出,故不太适应化工行业的发展,建立新的化工行业污染物排放标准势在必行。文章概要介绍了我国现有污染物排放标准,分析了美国、欧盟、日本、德国等一些国家和组织的排放标准,提议建立能够体现化工行业特点的行业排放标准,以达到淘汰落后工艺和促进清洁工艺的目的。

Adsorption selectivity of salicylic acid and 5-sulfosalicylic acid onto hypercrosslinked polymeric adsorbents

Both bottle-point and column-feeding experiments involving different solutes and sorbents were carried out to investigate the adsorption selectivity and separation performance of salicylic acid and 5-sulfosalicylic acid. Their adsorption isotherms onto such hypercrosslinked polymeric adsorbents as NDA-100 and NDA-99 could be well described by the Freundlich equations whose characteristics describe extrathermic and favorable adsorption processes. The adsorption towards NDA-100 mainly depended on the π-π interaction, while that towards NDA-99 was extremely influenced by the static-electric interaction. Additionally, the adsorptive capacity of salicylic acid on NDA-99 decreased while it increased on NDA-100 with the presence of 5-sulfosalicylic acid in the adsorptive environment as the competitive component. Comparatively, the adsorption capacity of 5-sulfosalicylic acid decreased on both resins with salicylic acid as the competitive component. In fact, the difference in the interaction between adsorbent and adsorbate resulted in the straight antagonism on the effective adsorption sites on the adsorbent. In conclusion, the adsorption selectivity of salicylic acid onto NDA-100 was obviously larger than that onto NDA-99 with the existence of 5-sulfosalicylic acid in the adsorptive environment. A satisfactory separation and recovery of tested solutes in aqueous phase could be foreseeably achieved by the sequencing adsorption technique involving NDA-100 as well as NDA-99.

地塞米松生产中毒性物质泄漏的定性定量分析

采用预先危险性分析和事故树分析剖地塞米松生产过程中毒物质产生中毒事故的危险性。指出溴甲烷和氟化氢是典型毒物。同时，利用泄漏和扩散模型定量分析它们泄漏所造成的危险性。结果表明：溴甲烷泄漏时，地面轴线浓度可以达到９２．３ｍｇ／ｍ＾３，远大于其急性中毒阈值，并制定了相应的预防性工程措施。
