| 摘 要： | 选取粗砂、粉煤灰、细煤渣、活性炭和空心砖粉块作为介质，再按适当的比例配成填料处理柱，进行处理低浓度生活污水的研究。经过两阶段的试验研究表明：粉煤灰和细煤渣配合使用去除COD的效果最好，达到了70%。粉煤灰和空心砖粉块配合使用去除NH3-N和TP的综合效果最好，分别达到了89％和81％。同时，发现活性炭在处理效果上无明显优势，并不经济实用。

| Abstract: | Grit,fly ash,cinder residue,active carbon,air brick detritus were used as filtering media according to proper proportion for low concentration domestic sewage treatment.The results of two stage operation showed that the removal rates of COD was good and high up to 70% by substrates combination of flyash and cinder.The removal rates of NH_3-N and TP were the highest and high up to 89% and 81% respectively by combination of fly ash and airbrick detritus.The removal efficiency of substrates combination of active carbon and other substrates were not the best,and its price was more expensive than other substrates,so it was not practical. |
