- 摘要:
- 惠州某河道主要支流水污染治理项目实施了截污、补水工程，以超磁+曝气生物滤池为核心工艺，将截留污水进行就地处理排回河道，实现水体的净化及循环流动，满足生态景观要求。实际工程运行结果表明，曝气生物滤池技术具有停留时间短、占地小的特点，处理后出水水质优于《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准，其中COD、NH3-N达到《地表水环境质量标准》（GB 3838—2002）Ⅴ类标准，同时采用模块化装备的建造模式，安装便捷，建设周期短，可异地搬迁，尤其适用于城市黑臭水体治理分散式就地处理工程。
- Abstract:
- The sewage interception and water replenishment projects were implemented in main branch of a river in Huizhou. With the core process of super magnetic and biological aerated filter (BAF), the intercepted sewage was treated on-site and discharge back to the river, so as to realize the purification and circulation of water body and meet the requirements of ecological landscape. The actual operation results showed that the BAF technology had the features of short retention time and small footprint, and the effluent quality after treatment was superior to the first level A criteria in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), in which COD and NH3-N reached the level Ⅴ criteria in Environmental Quality Standard for Surface Water (GB 3838-2002). Meanwhile, the modular equipment construction mode had the advantages of convenient installation, short construction period and remote relocation, which were especially adaptable for decentralized onsite treatment of urban black and odorous water body.
