摘要
组合工艺处理黄河微污染水研究表明 ,生物预处理和常规处理能有效去除CODMn和UV2 54,而臭氧的投加能有效提高深度处理工艺对CODMn和UV2. 54 的去除效果。组合工艺各单元都能有效地去除藻类、Chla和三氯甲烷前体物。陶粒生物滤池对氨氮有较高的去除率。投加臭氧时深度处理工艺对氨氮的处理效果会变差。在整个试验期间 ,组合工艺最终出水亚硝酸盐氮浓度低于 0 . 0 0 3mg L ,有时甚至低于检测限。
The treatment of slightly polluted Yellow River water was investigated using a combined process.COD Mn and UV 254 could be effectively reduced by biological pretreatment unit and conventional treatment unit.Addition of ozone could greatly improve COD Mn and UV 254 removal efficiency by advanced treatment unit.Moreover,each unit of the combined process could effectively remove alga,chlorophyll a (Chla) and chloroform precursors.Ammonia removal by bio ceramic filter was high.During the period of ozone addition ammonia removal by advanced treatment unit became worse.The final effuent nitrite remained less than 0.003 mg/L,sometimes even below detection limit.
