摘要
对上海陆家大桥水厂生物接触氧化预处理与常规工艺组合除污染进行了总结。一年多的生产运行结果表明 :生化池氨氮的去除效果主要受水温影响 ,水温较高时 ( >1 0℃ ) ,生化池氨氮平均去除率为 60 %左右 ,组合工艺氨氮总去除率为 76 73%～ 93 4 3% ;水温较低时 ( 5～ 1 0℃ ) ,生化池氨氮平均去除率为 4 0 %左右 ,组合工艺氨氮总去除率为 4 7 38%～ 65 31 % ;生化池CODMn去除率为2 2 2 %～ 1 0 99% ,组合工艺CODMn总去除率为 2 4 1 1 %～ 4 2 66% ;组合工艺对NO- 2 -N、Fe和Mn的总去除率分别为 97 93%、96 59%和 67 0 3% ;较高的原水浊度对生化池去除氨氮效果没有明显影响。
The combination of Biological Contact Oxidation Pretreatment (BCOP) and conventional water treatment process to purify polluted raw water has been conducted for over a year in the Big Lujia Bridge Water Plant in Shanghai. The obtained results show that NH 3-N removal efficiency of BCOP is affected greatly by water temperature; the NH 3-N removal ratio of BCOP is around 60% and 40% at higher water temperature (>10℃) and the lower water temperature (5～10℃) respectively; the COD Mn removal ratio of BCOP is 2 22%～10 99%. The removal ratios of NH 3-N, COD Mn , NO 2-N, Fe and Mn for combination process are 76 73%～93 43%(>10℃) or 47 38%～65 31%(5～10℃), 24 11%～42 66%, 97 93%, 96 59% and 67 03% respectively. Higher turbidity (from 50 to 300 NTU) of raw water has no significant effect on removal efficiency of NH 3-N.
