摘要
本文考察了UV/O3法对城市污水深度处理过程中的主要影响因素。结果表明有机污泥对COD去除率基本没有影响,但无机悬浮物Si O2对COD去除率影响较大,投加70mg/L的Si O2后COD氧化速率和去除率有较明显下降。UV/O3法处理城市污水生化处理水时,在pH=6～9范围内,COD去除率随pH值的升高而降低,说明较低pH值(pH=5)有利于COD的去除。随溶液碱度的增加,COD的去除率下降,碱度越高对COD去除的影响也越明显。SS、pH和碱度对UV260去除的影响均小于对COD去除的影响。
The AOPs （advanced oxidation processes） are valuable techonolgoies for municipal sewage advanced treatment. The inluencing factors of UV/O3, including pH, SS and alkalinity are studied. Inorganic SS has great effect on the COD removal process, but organic SS has little effect. The COD removal ratio increases with pH decreasing, and thus lower pH gets better results. With the alkalinity increasing, the COD removal falls down; SS, pH and alkalinity have less effect on UV260 removal.
