摘　　要：研究了催化铁内电解法对城市生活污水生化出水色度去除的影响。喷淋式装置的水力停留时间2h,当铁铜比例为12∶1,出水色度值最低,基本都在10以下。当铁铜质量比为4∶1时,TN去除率可以达到10%以上;出水NO3^-减少量最大,去除率大约为24.5%;NH4^+的增加量可以达到3mg/L左右。The effect of catalytic ferroelectrolysis on the chromaticity removal of biochemical effluent from municipal sewage was studied.The hydraulic retention time of the spray device is 2h.When the iron-copper ratio is 12∶1, the chroma value of the outlet water is the lowest, which is basically below 10.When the iron-copper mass ratio is 4∶1, TN removal rate can reach more than 10%.NO3^- decreased the most, and the removal rate was about 24.5%.The increase of NH4^+ can reach about 3mg/L.
