摘要
为改善大泊口水域水质,2015年开展了水污染综合治理示范工程,工程实施后,水质指标COD、BOD、TN、TP、叶绿素a削减率分别为:34.9%、35.2%、45.0%、26.5%和49.4%。研究认为水体TP低于0.068mg/L时,大泊口水域水体叶绿素a浓度低于0.05mg/L,因此TP低于0.068mg/L是促进良性水生态系统重建的重要条件。
Water pollution comprehensive treatment demonstration project was implemented in 2015 in order to improve water quality of Dabokou River Basin. After the project is implemented,water quality indexes COD,BOD,TN,TP,chlorophyll a reduction rate are respectively shown as follows: 34. 9%,35. 2%,45. 0%,26. 5% and 49. 4%. Research shows when water TP is lower than 0. 068 mg / L,Dabokou water chlorophyll a concentration is lower than 0. 05 mg / L,therefore TP lower than 0. 068 mg / L is important condition for promoting reconstruction of healthy aquatic ecosystem.
