两级碟管式反渗透系统在垃圾渗滤液处理中的应用
Application of Two Stage Disc Tube Reverse Osmosis System in Landfill Leachate Treatment
摘要
Abstract
This paper studied the application of two stage disc tube reverse osmosis (DTRO) system in the treatment of landfill leachate in a municipal solid waste landfill in Sichuan. The research showed that the concentration polarization phenomenon still existed in DTRO. Under normal condition and after pretreatment, the removal rate of NH + 4-N at first stage DTRO can reach 95. 1％ ～ 97. 8 ％, the desalting rate was 96. 6％ ～ 97. 7 ％, the removal rate of UV254 was 96. 4％ ～ 97. 4 ％. In second stage DTRO, the removal rate of NH + 4-N was 86. 5％ ～ 92. 1 ％, the desalting rate was 87. 2％ ～ 89. 6 ％, and the removal rate of UV254 was only 10％ ～ 40 ％. With the increase of the operating pressure of the two stage DTRO, the membrane flux increased and the removal rate of NH + 4-N and the desalination rate decreased.关键词
