某市城区污水管网水质变化规律
|
摘要
选取某市一段长为10.3 km的污水管线,分析研究了城市污水管网水质的变化规律。结果表明,生活污水流经城市生活污水管网后,水质发生了变化,其中SS、BOD_5、COD_(Cr)、NH_3-N、TN和TP的去除率分别为17.3%～62.3%、8.2%～42.7%、26.4%～67.2%、8.3%～28.2%、10.6%～20.5%和6.1%～13.7%。另外,沉积作用和生物降解作用对TCOD的去除贡献分别为55.19%和44.81%,对TN的去除贡献分别为43.57%和56.43%。
A 10.3-km-long sewage pipeline in a city was selected to investigate the variation regulation of water quality in urban sewer network. Results showed that water quality of domestic sewage changed along urban sewage pipeline, and removal efficiencies of SS,BOD_5, COD_(Cr),NH_3-N, TN and TP were 17.3%～62.3%, 8.2%～42.7%, 26.4%～67.2%, 8.3%～28.2%, 10.6%～20.5% and6. 1%～13. 7%,respectively. Furthermore,sedimentation and biodegradation accounted for 55. 19% and 44. 81% of TCOD removal,43. 57% and 56. 43% of TN removal.
