- Abstract:
- The expanding capacity of a sewage treatment plant in Shanwei, Guangdong Province is 10 000 m3/d, and the influent organic matter concentration is low. CBM process including lateral flow high-efficiency coagulation, flocculation and clarification tank (CBC module), biological aerated filter (BAF module), as well as multi-functional deep-bed filter (MDF module) developed by Shenzhen Qingquan Water Industry Co.Ltd. is used. The effluent quality is superior to the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002), actually meets level quasi-Ⅳ in Environmental Quality Standards for Surface Water (GB 3838-2002). The process takes full advantage of high efficiency of precipitation and biofilm treatment with carbonization, nitrification and denitrification. The total retention time is 3.5 h, and it could precisely remove nitrogen and phosphorus step by step. At the same time, the project was implemented with standard modular equipment, which has the advantages of small land occupation (total area of 800 m2), short construction period (total construction period of 90 days) and low operating cost (about 0.216 yuan/m3).
