厌氧反应器废水资源化过程在线监测系统
Online monitoring system of anaerobic reactor in processes of transforming wastewater into resources
摘要
Abstract
In order to overcome the hysteresis of current off-line state analysis of the anaerobic reactor, make full use of the resources and improve the status of wastewater discharge, an online monitoring system was studied in the process of transforming wastewater into resources based on fluorescence spectra. Tryptophan, ribo-flavin and coenzyme are taken as key monitoring components of the anaerobic reactor, the filter wheel are automatically located and flashes of the pulsed xenon lamp controlled. The fluorescence signals are collected by a photomultiplier tube. To deal with the mixed system of reaction products, the concept of quasi-three-dimensional fluorescence spectra, which transforms three-dimensional data into two-dimensional, was put forward and an optimized 3×3 fluorescence intensity matrix was obtained by optimizing the model parameters with partial least squares method. The three key process products in the reactor were detected online in real-time, added up and analyzed with a recovery ratio ranging from 85% to 112% .关键词
