In order to reduce the microfauna leakage risk from a granular biological activated carbon （GBAC） reactor which employs granular activated carbon （GAC） as adsorption media in drinking water advanced treatment, a novel fiber and granular biological activated carbon （FGBAC） reactor which employs both GAC and activated carbon fiber （ACF） as adsorption media, was developed. The results showed that the species composition of microfauna leaking from FGBAC reactor is almost similar to that leaking from GBAC reactor, however the densities of microfauna leaking from FGBAC reactor is reduced by 26%-81% compared to those leaking from GBAC reactor. In addition, compared to GBAC reactor, FGBAC reactor can increase the removal efflciencies of chemical oxygen demand （COD） and turbidity by 7% and 10%, respectively, during the stable operation period of reactor. 相似文献

采用物化活化工艺,以枣椰仁为原材料制作颗粒活性碳( GAC) ,制作过程主要有 6 个步骤: 清洗,烘干,粉碎,筛分,炭化和活化. 通过小试对新型 GAC 去除余氯的特性进行了研究,并将实验结果与 Langmuir和 Freundlich 等温方程进行了拟合. 通过理论和实验分析,考察了主要运行参数对吸附动力的影响. 结果表明: Langmuir 等温方程与实验数据最为吻合,说明其对余氯吸附为单层吸附. 新型 GAC 在余氯吸附方面具有巨大潜力,比传统的吸附剂更具竞争力. 采用托马斯扩展模型结合物质转移阻力对实验结果进行了验证,模拟结果与实验非常符合. 相似文献

This paper focused on the removal and transformation of the dissolved organic matter （DOM） in secondary effluent during the granular activated carbon （GAC） treatment. Using XAD-8/XAD-4 resins, DOM was fractionated into five classes： hydrophobic acid （HPO-A）, hydrophobic neutral （HPO-N）, transphilic acid （TPI-A）, transphilic neutral （TPI-N） and hydrophilic fraction （HPI）. Subsequently, the water quality parameters of dissolved organic carbon （DOC）, absorbance of ultraviolet light at 254 nm （UV-254）, specific ultraviolet light absorbance （SUVA） and trihalomethane formation potential （THMFP） were analyzed for the unfractionated and fractionated water samples. The results showed that the order of the DOC removal with respect to DOM fractions was observed to be HPI〉HPO-A〉HPO-N〉TPI-A〉TPI-N. During the GAC treatment, the THMFP of the unfractionated water samples decreased from 397.4 μg/L to 176.5 μg/L, resulting in a removal efficiency of 55.6%. The removal order of the trilaalomethanes （THMs） precursor was as follows： HPO-A〉TPI-A〉TPI-N〉HPO-N〉HPI. By the GAC treatment, the specific THMFP of HPO-A, TPI-A, TPI-N and the original unfractionated water samples had a noticeable decrease, while that of HPO-N and HPI showed a converse trend. The Fourier transform infrared （FTIR） results showed that the hydroxide groups, carboxylic acids, aliphatic C-H were significantly reduced by GAC treatment. 相似文献

The primary purpose of this study was to investigate the effectiveness of two different types of interviews—one that did (POSTICM) and one that did not (POSTI) embed a concept-mapping process—to elicit students' postinstructional understandings about chlorofluorocarbons and their role in global atmospheric change (GAC). A chief criterion measure was accordance, the degree to which students held the ideal postinstructional understanding set forth in a teacher-expert concept map. After GAC instruction that included concept-mapping activities, 34 eighth-grade science students were assigned randomly to groups and completed either POSTICM or POSTI. These students and their teacher also completed relatedness ratings of central concepts from the teacher-expert map. The Knowledge Network Organizing Tool™ was used to transform relatedness ratings to Pathfinder networks and compare nets to yield a student to teacher similarity index (Pathfinder index). Regression analysis revealed that type of interview did not predict accordance. However, most POSTICM students perceived the concept-mapping interview component to be helpful and affect positively their answers to the interview questions. The Pathfinder index did predict (p = .003) accordance—the Pathfinder index was a reliable confirmatory measure of the degree to which students held the ideal postinstructional understanding.
