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.
Abstract
The conventional treatment method for garbage percolate is biochemical treatment combined with nano-filtration,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 to-tal 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 opti-mization of the treatment process for garbage percolate nanofiltration concentrate.
