Research and application of on-line early warning system for source water quality of reclaimed water plant
摘要
Abstract
On-line early warning system (EWS) for source water quality of reclaimed water plant could guarantee secure and stable operation of treatment process. A reclaimed water plant at T city in northern China was introduced as an example, variation of main pollution indicators for source water of the plant were analyzed and pH, COD, TN, NH3-N, TP and SS were selected as key early warning indicators according to the characteristics and requirement of MBR process in the plant. A water quality forecasting method coupling with artificial neural network was proposed based on on-line water quality monitoring system. Taking into account of historical operation records, warning levels were set and emergency response program were established. Theoretical framework of on-line source water EWS was presented and the EWS software was developed. The results demonstrated that the on-line source water EWS could optimize and adjust order and parameters of the treatment process in real time and it was a significant tool for secure and stable operation of reclaimed water plant.关键词
