半饱和褐煤活性焦预吸附—4级固定化生物滤池降解—褐煤活性焦吸附组合工艺处理超稠油废水
Treatment of super heavy oil wastewater by combination process of half saturated lignite activated coke pre-adsorption-4-stage immobilized biofilter degradation-lignite activated coke adsorption
摘要
Abstract
The super heavy oil wastewater (SHOW)was treated by combination process of half saturated lignite activated coke (HSLAC)pre-adsorption-4-stageimmobilizedbiofilters (Ⅰ-BFs)degradation-lignite activated coke (LAC)adsorption.The experimental results indicated that:The effluent by the combination process met the discharge standard (COD ≤ 50 mg/L);By the 4-stage Ⅰ-BFs process,organic acids,esters and furans were completely removed,phenolics were partly removed,but amides were not removed,the macromolecular organic compounds were degraded into small molecular alkanes;The removal rate and removal amount of hydrophobic organic carbon and neutral organics were high by the Ⅰ-BFs,but humus and building blocks were hardly removed;Thedominant bacteria in the 4-stage Ⅰ-BFs were Bacteroides sp.,Pseudomonas sp.,Thermomonas sp.,Sphingomonadaceae sp.,Sphingomonas sp.and Rhizobium sp..关键词
