The novel QSAR model contains four variables, of which square regression coefficient is 0.82, standard deviation is 0.10. The QSAR model obtained reveal the reliability and good predictivity for the prediction of the rate constants of aromatic pollutants.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"14 1","pages":"1492-1495"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74467505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an overview of the relationship between the ENSO and mean-monthly stream flows (1967-2008) of five hydrological stations in the Jiulong River in Fujian Province, Southeast China. Results show that in the 24-month life cycle of warm phase of ENSO (El Niño), it tends to have lower stream flows in the first spring (from March through May), and higher stream flows in the first winter (from December through February) and the second spring. During the period of cold phase of ENSO (La Niña), it tends to have lower stream flows in the first winter and the second spring. Meanwhile, a lag correlation between the mean-monthly stream flows and surface sea temperature anomalies is also examined. Results show that, during El Niño events, stream flows have strong lag correlations from zero to six months with surface sea temperature anomalies (r = 0.250-0.576 at the 99% level, the strongest ones are one to three months), and weak lag correlations from three to four months in the period of La Niña events (r = 0.238-0.289 at the 99%level) for the Jiulong River. The likely reason for the difference is that the typical El Niño events persist for some 18months, while a La Niña condition can last up to two years or more, so an further study finds that, during period of long LaNiña events (longer than two years), the stream flow responses to SSTA lags by two to five months, with stronger correlations between 0.339-0.559 at the 99% level. These conclusions are invaluable for management of water resources, particularly in the dry seasons of the watershed.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"47 1","pages":"2082-2085"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88494679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four different ferric oxide samples were synthesized by homogeneous precipitation of reflux at different drying and calcination conditions. The most active catalyst was characterized and used as catalyst in photo catalytic degradation process. The effect of key parameters including catalyst dose, solution pH, oxidant concentration were investigated. The results showed UV light alone played a little role in the degradation of wastewater in a short time and the presence of Fe2O3 could greatly promote the degradation of wastewater. The degradation of wastewater was favorable at pH 3. Optimum values of catalyst dose and oxidant concentration was found to be 1 g L-1 and 5 ¡ë (v/v), respectively. Under the optimum condition, the removal rate of COD reached 93.1% under ultraviolet irradiation for 3 h. Satisfactory results suggested the effectiveness of the heterogeneous photo catalytic system ofFe2O3/UV/H2O2 in eliminating COD of paper mill effluent.
