【摘要】 研究了一体式粉末活性炭-微滤(PAC-MF)组合工艺对有机物、农药和氨氮的去除效果,并量化了粉末活性炭-微滤工艺中PAC、微生物和MF分别对去除污染物的贡献.结果表明,PAC-MF组合工艺对TOC、UV254、以及THMFP和HAAFP的平均去除率分别为73.56%、96.75%、77.64%、83%,对敌敌畏的平均去除率为95.1%,对氨氮的平均去除率可达98%.粉末活性炭-微滤工艺中,活性炭能够使膜的有机负荷降至膜直接过滤工艺的28.32%,膜表面的炭层对污染物有去除作用;活性炭在一次性高浓度的投加方式下,可以提高活性炭对氨氮的吸附作用,使对氨氮的去除率达44.5%.更多还原

【Abstract】 The removal effects by PAC-MF integrated system for organic matters,pesticides and ammonia-nitrogen are introduced.The separate contribution of PAC,microorganism and MF in the system are detailed quantitatively. The results indicate that the average removal rates of the integrated process for TOC,UV₂₅₄,THMFP and HAAFP are 73.56%,96.75%,77.64%,83%,respectively,and 95.1% for pesticides dichlorvos,98% for ammonia-nitrogen.The results illustrate that PAC significantly reduces the membrane organic burden to 28.32% of the direct membrane filtration without PAC;and carbon layer on the surface of membrane has the removal effect for pollutants.Moreover,the PAC used in high concentration can largely improve its adsorption performance for ammonia-nitrogen,whose removal rate is 44.5%.更多还原
