Comparative study on typical treatment processes of garbage percolate nanofil-tration concentrate
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.
