AC/O3-BAC工艺去除微污染珠江原水的初步研究

REMOVAL OF MICRO-POLLUTED RAW WATER IN ZHUJIANG BY COMBINED PROCESS OF AC CATALYTIC OZONATION AND BIOLOGICALLY ACTIVATED CARBON

  • 摘要: 通过实验考察了活性炭(AC)催化臭氧氧化-生物活性炭(BAC)组合工艺用于处理珠江原水的净水效能,并与臭氧-活性炭工艺(O3-BAC)进行了比较.结果表明,AC/O3-BAC组合工艺对TOC、UV254、氨氮等指标均具有较好的去除效率,优化参数为:臭氧投加量50 mg/h、曝气量200 L/min、氧化时间15 min.在试验条件下AC/O3-BAC对TOC和CODMn的平均去除率为28.5%和50.3%,较BAC工艺去除TOC和CODMn分别提高16.0%和34.8%;较O3-BAC工艺去除TOC和CODMn分别提高4.9%和5.9%.3组合工艺对有机污染物的去除具有协同效应,有利于将大分子的有机物氧化为小分子的有机物,提高出水的可生化性,从而有利于后续的BAC对有机污染物的去除.

     

    Abstract: Removal effects of micro-polluted Zhujiang river raw water by a combined process of activated carbon catalytic ozonation and biologically activated carbon(AC/O3-BAC) were investigated which was also compared with that of the combination of ozonation and activated carbon(O3-BAC). It was demonstrated that the AC/O3-BAC combined process showed great advantage in removing TOC、UV254 and NH3-N under optimum conditions (ozone dosage: 50 mg/h; gas flow: 200 L/min; oxidation time: 15 min). Under optimum conditions, the TOC and CODMn was removed by 28.5% and 50.3% respectively in AC/O3-BAC, increasing by 16.0% and 34.8% respectively compared with BAC alone, and increasing by 4.9% and 5.9% respectively compared with O3-BAC. Three processes showed great synergetic effect for organic pollutant removal, AC/O3-BAC was more efficient than O3-BAC and BAC in oxidating big molecule aromatic compounds to small molecule compounds, which increased biodegradability of oxidation effluent and reduced more organic compounds in subsequent BAC unit.
