填料对新型曝气生物滤池污水处理效能试验研究

摘要

采用新型酶促厌氧填料、半软性填料、酶促好氧填料和PYC挂膜陶粒填料对两段错向流曝气生物滤池反应器进行污水处理试验研究,分析了4种填料对反应器污水处理效能的贡献并为反应器填料的选择提供科学依据.结果表明,以半软性填料和酶促好氧填料为组合填料的两段错向流曝气生物滤池反应器污水处理效能均优于其它填料.%A two-sect up and down flow biological aerated filter (TUDBAF), with enzyme-enhanced anaerobic bio-filling, semi-soft filling, enzyme-enhanced aerobic bio-filling and PYC filling, was used to treat domestic wastewater. It studied the effectiveness of the four types filling on the wastewater treatment reactor to provide scientific basis for the choice of filling. The results show that performance of TUDBAF with semi-soft filling and enzyme-enhanced aerobic bio-filling are superior to other fillings.
