- 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.
