摘要:
台州某污水处理厂为达到对出水达标率的高考核标准（TN不达标次数不超过3 次/a），在原改良A/A/O—高效混凝沉淀池—盘式滤池工艺基础上，增设组合生物滤池（DN+C/N型）—V型滤池（前置微絮凝）的深度处理提标工艺，将污水处理厂出水标准由一级A提高至《地表水环境质量标准》（GB 3838—2002）中的Ⅳ类标准（氨氮、总氮除外）。工程运行结果表明,在原水COD、BOD5、SS、NH3-N、TN、TP平均值分别为133.5、47.2、75.3、21.4、30.9、2.59 mg/L时，出水平均值分别为11.6、1.3、2.0、0.21、9.2、0.12 mg/L。工程运行中需注意控制进水跌水曝气对碳源的消耗及缺氧环境的破坏，保证适量碳源（50 mg/L）的供给和对反硝化池溶解氧的控制（小于1 mg/L）。
Abstract:
In order to meet the high assessment standard of effluent (TN fails to reach the standard no more than 3 times per year)， a combined biological filter (DN+C/N) and V-type filter (pre micro flocculation) advanced process was added on the basis of original improved A/A/O+highefficiency coagulation sedimentation tank+disc filter process in the upgrading project of a sewage treatment plant in Taizhou. The technology is expected to improve the effluent quality from first grade A standard to the Ⅳ class standard of Environmental Quality Standards for Surface Water (GB 3838-2002)(except for ammonia nitrogen, total nitrogen）. The project operation results showed that when the average values of COD, BOD5, SS, NH3-N, TN and TP of raw water were 133.5, 47.2, 75.3, 21.4, 30.9 and 2.59 mg/L, the average values of effluent were 11.6, 1.3, 2.0, 0.21, 9.2 and 0.12 mg/L, respectively. During the operation, attention should be paid to carbon source consumption and anoxic environment damage caused by water falling aeration, and ensure the supply of appropriate carbon source (50 mg/L) and the control of dissolved oxygen in denitrification tank (less than 1 mg/L).
