EFFECT OF ULTRAVIOLET DISINFECTION ON GROWTH AND SECRETION CHARACTERISTICS OF MICROORGANISM IN RECLAIMED WATER

  • 摘要: 膜污堵是阻碍污水再生处理反渗透(RO)系统稳定、高效运行的突出问题。前期研究表明,RO系统常用的氯消毒预处理会导致微生物群落结构及代谢产物分泌特性发生显著改变,从而引起严重的生物污堵。为优化污水再生处理RO系统的预处理工艺选择,该研究全面考察了紫外线消毒对再生水中细菌的生长、群落结构和分泌特性的影响。结果表明:紫外线剂量为20,40,80 mJ/cm2时,对膜生物反应器出水中细菌的灭活率分别可达1log、3log、4log。紫外消毒后,存活细菌再培养时其生长迟滞期变长,稳定期细菌数量在紫外线剂量为40,80 mJ/cm2时分别比对照组降低18.6%和19.2%。高紫外线剂量下(40,80 mJ/cm2),变形菌门、β-变形菌纲、詹森菌属相对丰度有所增加。分泌特性方面,细菌胞外多聚物含量随紫外线剂量升高先减少后增多,且其中大分子物质增多,并表现出更强的RO膜污堵潜势。
