摘　　要：垃圾渗滤液常规采用生化法结合纳滤法进行处理,其中纳滤系统会产生15%~30%水量的浓缩液。纳滤浓缩液主要水质特征为难降解有机物浓度高、总硬度高、硫酸盐浓度高等,处理难度较大。本文主要研究了两种纳滤浓缩液处理工艺,一种为零排放工艺,一种为达标排放工艺。阐明了两种工艺技术的原理、设计参数、处理效果、投资及运行成本等,对两者的工艺优缺点进行分析,为垃圾渗滤液纳滤浓缩液处理工艺设计及优化研究提供依据。The conventional treatment method for garbage percolate is biochemical treatment combined with nanofiltration,during which the nanofiltration system produces a concentrated solution of 15%to 30%water volume.The main characteristics of the nanofiltration concentrate are high concentration of refractory organic matter,high total hardness,and high sulfate concentration,making it difficult to treat.This article studies two types of nanofiltration concentrate treatment processes,one is a zero-discharge process and the other is a standard discharge process.This article elucidates the principles,design parameters,treatment effects,investment,and operating costs of the two processes,analyzes the advantages and disadvantages of both processes,and provides a basis for the design and optimization of the treatment process for garbage percolate nanofiltration concentrate.
