【摘要】本文针对在不同条件下的光化学氧化处理高浓度垃圾渗滤液,进行了改善其可生化性与提高NH3-N去除率的研究。在负载型TiO2催化剂催化下BOD5/CODcr值从0.064提高到0.228,超过了0.1的可生化性要求。二氧化钛催化剂对NH3-N去除效果明显,15minNH3-N去除率可达80.19%。更多还原

【Abstract】 This text is a research in light of photo-chemical oxidization conducting Landfill Leachate with high concentration,under different conditons,of improving its biodegradability and souping the removing of NH3-N.The value of BOD5/CODcr is increased from 0.064 to 0.228 via the catalysing of immobilized TiO2 catalysts,over 0.1,the reqirement of biodegradability.It’s efficient of TiO2 to remove NH3-H,which is up to 80.19% in 15min.更多还原
