【摘要】 为比较固定化生物炭工艺与普通活性炭工艺的净水效果,以南方某水厂的滤后水为原水进行了试验。结果表明,固定化生物炭工艺对TOC的去除率稳定在40% ~50%,可以提高氨氮去除率30%;对三卤甲烷生成势(THMFP)的去除率比普通活性炭工艺提高了11% ~39%;对臭氧氧化副产物(甲醛)具有长期的去除效果。更多还原

【Abstract】 Experiment was made in a water treatment plant in south area by using its filtered water as raw water, in order to make comparison between immobilized biological activated carbon (BAC) and conventional activated carbon(AC) process for their water treatment efficiency. The result shows that immobilized BAC process can remove 40%-50% of TOC, and can increase removal rate of ammonia nitrogen by 30%; the removal rate of trihalomethane formation potential (THMFP) is raised by 11%-39% as compared with conventional AC process; the process can remove ozonation byproduct (formaldehyde) for a long period.更多还原
