| 摘 要： | 以玄武岩纤维(BF)作为生物填料应用于生活污水处理,选取BF进行生物巢培养,并对生物巢形成时间进行了对比分析,探究了不同BF水中COD、氨氮和总氮的去除效果。结果表明:BF三种BF填料布置间距对COD、氨氮和总氮的去除率总体上随水力停留时间(HRT)的延长而提高,BF填时,对生活污水中COD、氨氮和总氮的去除率分别达到88.4%、83.3%和64.7%。

| Abstract: | Basalt fiber(BF) was used as bio-filler for domestic sewage treatment. The nesting spacing of BF packing was 15, 20, 25 cm, respectively, and the nesting time of biological nest was analyzed. The removal effect of different BF packing spacing on COD, ammonia nitrogen and total nitrogen in domestic sewage was explored. The results show that the biological nest formation time is the shortest when the spacing of BF packing is 20 cm. The removal rates of COD, ammonia nitrogen and total nitrogen in the three BF packing arrangements generally increase with the extension of HRT. The treatment effect is best when the spacing of BF packing is 20 cm. When the HRT is 12 h, the removal rates of the COD, ammonia nitrogen and total nitrogen of domestic sewage reach 88.4%, 83.3% and 64.7%, respectively. |
