A novel two stage circulating biological aerated filter (CBAF) was used to treat the alkaline wastewater after its neutralization. The factors of various air/water volumetric ratio, hydraulic retention time (HRT), which affected the removal of COD, sulfide, phenol and oil pollutants were investigated. The experimental results show that, when the wastewater feed flow rate is 0.5 m3¡¤h-1, the air/water volumetric ratio is 24:1 with the HRT of 4 h for single CBA Freactor, the influent average concentrations of COD, sulfide, phenol and oil pollutants are 1371, 234, 181 and81.4 mg¡¤L-1, respectively. After two stage CBAF reactor treatment, the total average removal rates of COD, sulfide, phenol and oil pollutants are 72.0, 98.8, 79.6 and85.2 %, respectively. And the average effluent concentration of COD, sulfide, phenol and oil pollutants are 384, 2.90, 37.0 and 12.0 mg¡¤L-1, respectively. The results demonstrate that the CBAF reactor is a kind of high efficiency and low cost treatment technique which has a good application foreground for the treatment of the alkaline wastewater from oil refinery.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"14 1","pages":"2360-2365"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77720948","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}

The microwave digestion result showed that the concentration of zincin surficial sediments ranged from 568 mg/kg to 2126 mg/kg. The results of modified BCR sequential extraction procedure showed that heavy metal zinc in the surficial sediment was mainly associated with residual and acid soluble fractions. The fractions of zinc sampled near the drain were in the order of residual > acid soluble > oxidizable > reducible > water soluble fraction, and in the order of residual > reducible > acid soluble > oxidizable >>water soluble fraction in samples away from the drain. The results indicated that the concentration and fraction of pollutant zinc were significantly correlative to the drain of some iron and steel factory around the Shaxi River, which varied obviously with the downstream distance increasing to the drain. The acid soluble and oxidizable fractions decreased with the downstream distance increasing to the drain of iron and steel factory, however, the residual and reducible fractions increased with the distance increasing.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"36 10 1","pages":"2408-2411"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80178782","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}

The results of the elemental analysis, XRD, FT-IR and SEM characterization have confirmed the forming of the mimetite/pyromorphite solid solutions. The XRD analysis indicated that the end-member components of the solid solutions were well matched respectively to card #01-080-2103for mimetite and #00-019-0701 for pyromorphite, and their corresponding unit cell parameters. In FT-IR spectra, the stretching vibrational absorption band of AsO43- appeared around 788.71-820.00 cm-1 (¦Ã3), and the bending vibration absorption band was also visible at 418.00cm-1 (¦Ã4). In addition, no vibrations of AsO43- appeared at 1407.82 cm-1, 1563.44 cm-1and 1733.26 cm-1. There was a clear water peak of pyromorphite appeared at 3440.62 cm-1 and the anti symmetric stretching peak of PO43- appeared around 979.50-1050.05 cm-1(¦Ã3) and the symmetrical peak appeared around 540.08-575.53cm-1 (¦Ã4). Observed by SEM, the shape of crystals changed gradually from the fibrous, needle-like to the granular solid block as PO43- in the solids increased.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"3 1","pages":"1380-1383"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73122409","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}
