摘要
探讨利用粒状生物活性炭(GBAC)和固定粉状生物活性炭(IPBAC)对人工废水CODMn处理的效果。结果表明,GBAC和IPBAC中微生物的生长(UV254)与运行周期密切相关。GBAC和IPBAC运行初期内,炭表面的生物膜逐步形成,微生物不稳定,从而导致UV254值波动较大。随着运行周期的延长,生物膜生长逐步趋于稳定。随着炭层高度的增长,生物活性炭对CODMn的去除率也越大。GBAC与IPBAC对CODMn都有很高的去除率,但GBAC对CODMn的去除率高于IPBAC。
Granular biological activated carbon （GBAC） and immobilized powder biological activated carbon （IPBAC） were used to remove CODM, from an artificial wastewater. The experimental results show that the growth of the microorganisms in the GBAC and IPBAC （UV254） has close relationships with GBAC and IPBAC operational cycle. The new biomembrane of GBAC and IPBAC carbon surface takes shapes gradually. In initial stage, the microorganisms were unstable, and caused UV254 value to fluctuate with time. With the extension of operational cycle, the biomembrane grew and became stabile. With the height of carbon layer increased, the CODM, removal also increased, with GBAC was more effectively than IPBAC.
