黑臭河道生态治理综合技术研究与应用实例
|
摘要
对城市河道黑臭水体采用"微纳气泡复氧系统+活性生态自由基+复合菌酶修复剂+景观生态浮床"生物生态综合治理技术进行治理。结果表明,主要水质指标的CODMn、NH3-N、TP的最大净化率,平均分别达到了52.89%、77.84%和65.88%;DO含量和透明度的平均提升率为58.26%和210%;能短期内将原GB 3838-2002劣V类地表水治理净化成V类水,水质改善效果明显,取得了预期效果,值得在其它类似项目中推广。
The black-odor water of the city river was treated by comprehensive bio-ecological treatment of 'micro-nano-bubble oxygenation system+ active ecological free radical + compound bacterium enzyme repair agent + landscape ecological floating bed'. The results showed that, maximum purification rate of CODMn, NH3-N and TP of main water quality indexes reached 52.89%, 77.84% and 65.88%, respectively. The average increase rate of DO content and transparency was 58.26% and 210%, which could purify the bad-V-type black-odor river into V-type water of GB 3838-2002 in the short term, and the effect of water quality improved obviously and achieved expected effect, which is worth popularizing in other similar projects.
