用大型底栖动物和ODP系统评价珠江的有机污染

采用大型底栖动物需氧有机体百分率ODP(oxygen demander percentage)法对广州珠江前航道、西航道和流溪河的下游段进行河流有机污染评价.结果显示:底栖动物需氧类群密度在三河段间分布确有显著性差异,并根据其ODP可以判断流溪河水质相对较好,水质级别为中国地表水环境质量标准(EQSSW)Ⅳ级,西航道和前航道水质级别都为Ⅴ级.通过测试,这一方法能成功地应用在珠江及流溪河,且该法可以较好地匹配于EQSSW五级评价系统,初步认为ODP系统可以成为一个较好的河流水质生物监测方法.图3表4参13

两级SBR与传统SBR工艺的对比研究

用两级SBR工艺（TSSBR）处理COD与氮浓度较高的工业废水，SBR1去除有机物，SBR2主要进行硝化反硝化。TSSBR与传统SBR工艺相比，COD降解速率和硝化反应速率明显提高，COD去除率由84％提高到93％，2种工艺的反硝化速率没有明显差别。在原水COD浓度较高的情况下，TSSBR可有效克服高COD浓度对硝化反应的抑制，硝化反应速率是传统SBR的2倍。对于COD和氮浓度较高的工业废水，TSSBR明显优于传统SBR，是一种理想的处理工艺。

加碱混凝沉淀法去除蓝皮制革废水中Cr^3＋及COD的研究

取自扬州某外资皮革厂的蓝皮制革废水含有大量的Cr^3＋和COD。通过对该废水加各种碱剂调节其pH值至8．3～8．5，均可将Cr^3＋去除90％以上，且对COD也有一定的去除效果。再对该废水加碱的同时试采用几种混凝剂进行混凝，Cr^3＋和COD的去除率都得到提高。研究表明：通过加碱混凝能取得更好的去除效果，PAC／PAM是最佳混凝剂，最佳投药量为0．4g／L，Cr^3＋可降到国家标准以下。

First Europe-wide correlation analysis identifying factors best explaining the total nitrogen concentration in mosses

In this study, the indicative value of mosses as biomonitors of atmospheric nitrogen (N) depositions and air concentrations on the one hand and site-specific and regional factors which explain best the total N concentration in mosses on the other hand were investigated for the first time at a European scale using correlation analyses. The analyses included data from mosses collected from 2781 sites across Europe within the framework of the European moss survey 2005/6, which was coordinated by the International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops (ICP Vegetation). Modelled atmospheric N deposition and air concentration data were calculated using the Unified EMEP Model of the European Monitoring and Evaluation Programme (EMEP) of the Convention on Long-range Transboundary Air Pollution (CLRTAP). The modelled deposition and concentration data encompass various N compounds. In order to assess the correlations between moss tissue total N concentrations and the chosen predictors, Spearman rank correlation analysis and Classification and Regression Trees (CART) were applied. The Spearman rank correlation analysis showed that the total N concentration in mosses and modelled N depositions and air concentrations are significantly correlated (0.53 ≤ r_s ≤ 0.68, p < 0.001). Correlations with other predictors were lower than 0.55. The CART analysis indicated that the variation in the total N concentration in mosses was best explained by the variation in NH₄⁺ concentrations in air, followed by NO₂ concentrations in air, sampled moss species and total dry N deposition. The total N concentrations in mosses mirror land use-related atmospheric concentrations and depositions of N across Europe. In addition to already proven associations to measured N deposition on a local scale the study at hand gives a scientific prove on the association of N concentration in mosses and modelled deposition at the European scale.
