摘要：
利用自制的活性污泥曝气池，通过试验研究了投加轻质填料对该曝气池处理模拟生活污水效果的影响。试验结果表明，当进水CODCrCr、NH4+-N、TN和TP分别为101~136、7.87~20.01、22.14~29.16、1.76~2.74 mg/L时，投加轻质填料的活性污泥曝气池对污水中CODCrCr、NH4+-N、TN和TP的去除率分别达到83%、89%、60%和38%，与未投加轻质填料时相比，CODCrCr、NH4+-N、TN和TP去除率分别提高4%、9%、11%和3%。此项研究为污水处理厂曝气池的升级改造提供了一种新的方法。

Abstract:
A homemade activated sludge aerobic reactor has been used for the experimental research on the influence of adding light fillers to the activated sludge aerobic reactor on the effectiveness of simulated domestic sewage treat-ment. The results show that when the CODCrCr,NH4+-N,TN and TP of the influent are 101-136,7.87-20.01,22.14-29.16,1.76-2.74 mg/L,respectively,after adding the light fillers,the removing rates of CODCrCr,NH4+-N,TN and TP can reach 83%,89%,60% and 38%,respectively. Compared with the results before adding light fillers,the removing rates of CODCrCr,NH4+-N,TN and TP have increased 4%,9%,11%,and 3%,respectively. This research provides a practically new method for upgrading the existing aerobic reactor in sewage water treatment plants.
