摘要
针对北方某大型净水厂3种不同炭龄的颗粒活性炭,对其物理特性和典型水质指标去除效果进行研究,结果表明,颗粒活性炭使用5年后,其吸附值等物理特性趋于稳定;颗粒活性炭表面的酸杆菌、根瘤菌等微生物对去除水中有机物发挥了重要作用;碘吸附值和亚甲基蓝吸附值不是颗粒活性炭再生更换的主要指标;可考虑延长新炭再生时间至5年。
Based on the research results of the physical properties of three kinds oi granular activated carbons （GAC） with different ages and their removal effects shown by the typical water quality index, it was found that after 5 yearg use of GAC, the adsorption value and other physical properties tended to be a stable value; the microorganism such as acid bacillus and rhizobium, played an important role in the removal of organic matter in water; the adsorption values of iodine and methylene blue would not be the main indicators of the requirements of the replacement and regeneration of activated carbon and the regeneration of new GAC was recommended to be carried out 5 years later.
