HCR技术在印染废水处理改造中的应用

通过对某印染公司原有设施的改造,把HCR技术应用在废水改造中。进水量为11000m3/d,COD2200～2500mg/L,pH12左右,色度600～800倍,改造后运行稳定,废水处理效果有大幅提高,出水COD为360mg/L、色度为300倍均能达标排放,其去除率分别为86%、50%。     

Treatment of a dyeing wastewater from a woolen mill using an A/O membrane bio-reactor

An anaerobic/oxic membrane bioreactor (A/O MBR) was used for treatment of dyeing wastewater from a woolen mill.COD and color of the wastewater were 54-473 mg/L and 40-400 dilution time (DT) respectively. The ratio of BOD5/COD was less than 0.13. By the A/O MBR process, the average removal of COD, BOD5, color and turbidity was 82％, 96％, 71％ and 99％, respectively. The average COD, BOD5, color and turbidity of effluent was 37 nag/L, 0.8 mg/L, 40 DT and 0.44 NUT respectively. The effluent COD met the local standard of reuse water in Beijing, China. The average COD volume load of the anaerobic biological tank was 0. 0483 kgCOD/(m3·d) and that of the aeration tank of the MBR was 0. 3589 kgCOD/(m3·d). The sludge load of the MBR was 0.19 kgCOD/(kg· MLSS· d) on average and the maximum of that was 0.4 kgCOD/( kg· MLSS· d).The flux of the A/O membrane bioreactor could be remained at larger than 50 L/(h· m2· 0.1MPa). The results indicated that A/O membrane bioreactor has technical feasibility for treatment of woolen mill wastewater.

论现代科学技术中的"生态化"

对现代科学技术所出现的“生态化”现象进行了初步探讨。首先，对生态学涵义的扩展和生态化研究方法进行了研究，认为其涵义已从生态学的生物学含义发展到现代生态学的新涵义，其方法就是研究在科学技术中的“对象”与“环境”的关系问题；在此基础上，对科学技术研究目标作了生态化表述，即要建设生态-经济-社会优质复合群；然后，对科学技术所出现的生态化理论与方法进行了初步研究，并对建设普遍优质的生态-经济-社会复合群理论及其应用进行了分析；最后，对生态化的研究方法进行了总结。     

渤海海水淡化反渗透法的预处理工艺

采用“消毒-混凝-澄清一砂滤”、“消毒-混凝-澄清-砂滤-超滤”以及“消毒-砂滤-超滤”三套海水淡化预处理工艺进行了试验对比。试验的目的在于获取可行的反渗透预处理工艺。表明,采用“消毒-混凝-澄清-砂滤-超滤”工艺或“消毒-砂滤-超滤”工艺是技术可行的反渗透预处理工艺,其中次氯酸钠为可选消毒剂,三氯化铁为较好的混凝剂,而超滤是不可或缺的单元处理工艺。

Water technology for specific water usage

BACKGROUND: Water is the basis for life and culture. In addition to the availability of water its quality has become a major issue in industrialized areas and in developing countries as well. Water usage has to be seen as part of the hydrological cycle. As a consequence water management has to be sustainable. The aim of the contribution is to give water usage oriented quality criteria and to focus on the technical means to achieve them. MAIN FEATURES: Water is used for many purposes, ranging from drinking and irrigation to a broad variety of technical processes. Most applications need specific hygienic, chemical and/or physical properties. RESULTS: To meet these demands separation and reaction principles are applied. The reuse of water and the application of water treatment with little or no waste and by-product formation is the way to go. Membrane separation and advanced oxidation including catalytic reactions are promising methods that apply natural processes in sustainable technical performance. Thus elimination of specific water constituents (e.g. salts and metals, microorganisms) and waste water cleaning (e.g. pollutants, nutrients and organic water) can be done efficiently. OUTLOOK: Learning from nature and helping nature with appropriate technology is a convincing strategy for sustainable water management.
