针对新型中置炭滤池-消毒-砂滤工艺,对比研究臭氧-中置炭滤池、中置曝气炭滤池和臭氧-中置曝气炭滤池对北江水源的净化效果,为南方某水厂提供工艺优化设计方案。结果表明,臭氧对难降解有机物去除较有优势;对于难降解有机物含量较少的北江水源,采用曝气活性炭滤池可以保持对有机物的去除效果,同时可提高氨氮的硝化效率,并降低成本;臭氧-曝气-中置炭滤池工艺对净水效果并无明显改善,不推荐使用。
According to the new type of middle carbon filter - disinfection - sand filtration process, the purification effect of Beijiang water source by ozone - middle carbon filter, middle aeration carbon filter and ozone - middle aeration carbon filter was compared, A water plant to provide process optimization design. The results show that ozone has more advantages for the removal of refractory organic matter. For the Beijiang water with less organic matter, aeration activated carbon filter can keep the removal of organic matter and improve the nitrification efficiency of ammonia nitrogen and reduce the cost. Ozone - aeration - in the carbon filter process has no significant effect on water purification, not recommended.
