摘　　要：选用多孔波纹板填料、YDT型弹性立体填料和堆积式卷发器填料作为净化槽中的生物滤床,研究不同生物滤床对家庭生活污水的处理效果,在相同的运行参数条件下,对比分析了3种填料对生活污水中COD、BOD5和NH3-N的去除能力。结果表明,波纹板填料对COD和BOD5具有较强的降解作用,出水平均值分别达到35 mg.L-1和10.9 mg.L-1;而YDT型弹性立体填料对COD、BOD5去除能力略小于波纹板填料,但对NH3-N处理效果更好,出水NH3-N平均值达到5.9 mg.L-1;堆积式卷发器填料由于较低的比表面积,而显示出较低的处理效果。The pE corrugated plate carder, YDT stereo elastic carder and the stacked style hair volume carrier are used in purifying tank for treating domestic sewage. In the same operational condition, the results show that the PE corrugated plate carrier has higher removal efficiency of COD and BOD5 in sewage. The average effluent values of this carrier are 35 mg·L-1 and 10.9 mg·L-1, respectively. And the YDT stereo elastic carrier has lower removal efficiency of COD and BOD5 than the PE corrugated plate carrier, but the removal efficiency of NH3-N is the highest of all the three kinds of carders. The average effluent value of this carrier is 5.9 mg·L-1.As the small specific surface area of the stacked style hair volume carrier, it shows lower treatment efficiency.
