摘要
以常州市白荡浜黑臭河道水体治理为目标,应用生态修复技术治理城市黑臭河道,通过曝气造流、底质改性、种植水生植物、构建水生微生物种群等措施对该水体进行治理修复。结果表明:经过4个月的调试和运行,该河道水质有了明显改善,DO从0.21 mg/L增加到3.8 mg/L,对COD、BOD5、氨氮和TP的去除率分别达到了57.8%、72.4%、41%和55.6%,水体透明度从15cm上升到40 cm以上。实践证明,该工艺能够有效去除水中有机物、氨氮、总磷等污染物,增加水体的溶解氧和透明度,在技术上是可行的,若同时加强环保监管与定期运行管理,则可从根本上恢复河流系统的生态。
Ecological measures, such as making flow by aeration, modifying sediment, planting a- quatic plants, and constructing aquatic microbial population were taken to treat malodorous water from Baidangbang in Changzhou City. After the commissioning and operation for four months, the river water was significantly improved. DO was increased from 0.21 mg/L to 3.8 rag/L, the removal rates of COD, BODs, ammonia nitrogen and TP were 57.8% , 72.4% , 41% and 55.6% respectively, and the trans- parency was increased from 15 cm to above 40 cm. The findings show that it is technically feasible to use the above-mentioned measures to remove organic compounds, ammonia nitrogen and TP and to add DO and transparency. In addition, the environmental regulatory enhancement and the regular operation man- agement are helpful to restore the ecological environment of the river system.
