兼性生化处理生活污水最佳工况研究

在常温条件下进行兼性生化处理生活污水试验,研究COD去除率与HRT、MLSS、进水有机物浓度和混合液水温的关系。在试验中最佳的水平搭配为MLSS=5500mg/L,进水有机物浓度=180mg/L,HRT=8h和混合液水温=20℃,与回归分析所得出MLSS=5881mg/L,进水有机物浓度=192.7mg/L,HRT=8.9063h和混合液水温=21.3790℃的最佳工艺条件相吻合。最后通过等高线分析得出常温下生活污水兼性生化的适宜范围。     

悬浮颗粒物对黄河铜的生物有效性影响的研究

利用t检验分析了悬浮颗粒物对黄河水体中铜的生物有效性的影响.结果表明,虽然过滤后水样的EC50比未过滤水样的EC50高,但是过滤前后24h-EC50和48h-EC50在统计学上没有显著差异;而过滤前后72h-EC50和96h-EC50存在显著差异.通过分析,认为造成这种现象的原因有两个:(1)未过滤的水样泥沙含量阻碍了藻类的光合作用;(2)试验过程中水样的理化性质发生改变,导致颗粒物中吸附的铜再次发生了解吸现象。

青岛地区大气气溶胶海洋因子贡献研究

本文对青岛地区大气气溶胶海洋因子的贡献进行了分析研究，得出以下结构：（１）复季受海洋影响要比冬季明显得多；（２）就质量浓度而言，ＩＰ（ｉｎｈａｌａｂｌｅ ｐａｒｔｉｃｌｅ）中的海盐源要高于ＴＳＰ（ｔｏｔａｌ ｓｕｓｐｅｎｄｅｄ ｐａｒｔｉｃｕｌａｔｅｓ）；（３）海洋影响的程度和离海边的距离有关。离海逾远，受海洋影响就逾小；离海连逾近，受其影响就逾大；（４）ＩＰ冬季海盐源为２％－４％，夏季为１０％－     

Total nitrogen and community turnover determine phosphorus use efficiency of phytoplankton along nutrient gradients in plateau lakes

Numerous studies support that biodiversity predict most to ecosystem functioning, but whether other factors display a more significant direct impact on ecosystem functioning than biodiversity remains to be studied. We investigated 398 samples of the phytoplankton phosphorus resource use efficiency (RUE_P = chlorophyll-a concentration/dissolved phosphate) across two seasons in nine plateau lakes in Yunnan Province, China. We identified the main contributors to phytoplankton RUE_P and analyzed their potential influences on RUE_P at different lake trophic states. The results showed that total nitrogen (TN) contributed the most to RUE_P among the nine lakes, whereas community turnover (measured as community dissimilarity) explained the most to RUE_P variation across the two seasons. Moreover, TN also influenced RUE_P by affecting biodiversity. Species richness (SR), functional attribute diversity (FAD2), and dendrogram-based functional diversity (FDc) were positively correlated with RUE_P in both seasons, while evenness was negatively correlated with RUE_P at the end of the rainy season. We also found that the effects of biodiversity and turnover on RUE_P depended on the lake trophic states. SR and FAD2 were positively correlated with RUE_P in all three trophic states. Evenness showed a negative correlation with RUE_P at the eutrophic and oligotrophic levels, but a positive correlation at the mesotrophic level. Turnover had a negative influence on RUE_P at the eutrophic level, but a positive influence at the mesotrophic and oligotrophic levels. Overall, our results suggested that multiple factors and nutrient states need to be considered when the ecosystem functioning predictors and the biodiversity-ecosystem functioning relationships are investigated.

丁基锡化合物在水体悬浮颗粒物上的吸附行为研究

将海河河口表层底泥制成悬浮颗粒物（ＳＰＭ），采用批量平衡法首次研究了模拟河口条件下三丁基锡（ＴＢＴ）和二丁基锡（ＤＢＴ）在该ＳＰＭ上的吸附行为．结果表明，ＴＢＴ和ＤＢＴ均能在ＳＰＭ上发生吸附，尤以ＴＢＴ更为显著．吸附速率可用Ｋｕｏ和Ｌａｋｅ的经验公式描述；吸附过程受ＳＰＭ的浓度及ＴＯＣ含量、ｐＨ值、温度、腐殖酸浓度和盐度影响．实际河口水样中的ＳＰＭ对ＴＢＴ和ＤＢＴ的吸附百分率也较高，因此ＳＰＭ是ＴＢＴ和ＤＢＴ归趋的重要场所，去除ＳＰＭ可使水体得到一定净化．     

烟气脱硫(FGD)工程设计框架

在国家实施“总量控制”和“两控区”的重要环境保护政策下,烟气脱硫（ＦＧＤ）工程提到了可持续发展的议事日程,实施ＦＧＤ工程是投资大、直接经济效益不显著的环境工程。因此在全面论述实施ＦＧＤ工程的设计框架,即各设计阶段应考虑的几个重大因素和必须遵循的一系列规则基础上,着重对目前国内外主要的ＦＧＤ工艺进行了技术经济分析评述,提出选择ＦＧＤ工艺的８条重要原则。供重大决策参考和推动环境目标的实现。
