摘要
为实现常州市水环境品质的再提升,实施了双桥浜水环境综合整治工程。通过采取控源截污、超磁分离技术生态补水、曝气造流、BioMat人工复氧、微动力MBBR和水体生态修复组合的方式来进行水环境品质的再提升。结果表明,组合工艺经过三个月的调试运行后,双桥浜消除了黑臭,DO由初始0.85mg/L增加到8.81mg/L,透明度由初始的30 cm到治理后的70 cm以上,对CODCr、氨氮和总磷的去除率分别达到53.3%、65.1%和76.3%。实践证明,该组合工艺适应于提升城市水环境品质。
Shuangqiao River comprehensive rehabilitation project was carried out for the quality improvement of urban water environment in Changzhou city. Integrated technologies, including pollutant source control, super-magnetic separation with ecological water supply, aeration turbulence, BioMat oxygen enrichment, micro-power MBBR, and ecological remediation, were combined and used in the system. The results shows that black and odorous water body was signifcantly removed after the treatment by the integrated technology system for 3 months. The dissolved oxygen was improved from 0.85 to 8.81 mg/L, while the transparency was increased from 30cm to over 70 cm. The removal of CODCr, ammonia nitrogen and TP reached 53.3%, 65.1% and 76.3%, respectively. The practice has proved that the integrated technology system is suitable for the quality improvement of urban water environment.
