不对称氧化铝膜管的微滤性能研究

采用熔模离心法制备的不对称氧化铝微滤膜管的孔径沿径向呈样度分布，控制层孔径均匀。最可几孔径为０．０５μｍ，最大孔径为０．１μｍ的管能滤原液中全部的细菌，获得完全无菌的水，但过滤速率太慢，最可几孔径为０．１μｍ，最大孔径为０．２μｍ、最大孔径０．３μｍ。     

小诺霉素发酵废水好氧生物处理试验研究

对具有强抑制性污染物的抗生素小诺霉素发酵废水，选择活性污泥、粉末活性炭（ＰＡＣＴ）、纯氧曝气等３种好氧生物处理法进行了比较试验。根据实验结果，小诺霉素发酵废水的生物降解呈抑制动力学，采用Ｍａｒｑｕａｒｔ方法对动力学模式进行参数估计。ＰＡＣＴ能够有效地降低降解过程中微生物受到的抑制作用，从而明显地改善了生物处理过程动力学。

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.
