Modeling Residual Chlorine Decay for Optimization of Booster Chlorination in Urban-rural Water Distribution System
The key procedure of optimization of the control of the booster chlorination is modeling the relationship between the concentration of the spot of the booster chlorination (after dosing) and the concentration of the monitoring points on the remote end of the water distribution. This relationship of residual chlorine decay is affected not only by periodical change of the water demand, but also by many other complex factors, e.g. the water temperature T, the concentration of the spot of the booster chlorination C0 and the water quality. In this text, the modeling research is based on the system of the booster chlorination in the urban-rural water distribution of JiaXing city. First, collect the data of the concentration of the monitoring points when adjusting the dose of the disinfection on the spots of the booster chlorination, meantime the water temperature and the water quality is also recorded. For the reason that the main factors of the residual chlorine decay includes periodical change of the water demand, the water temperature T and the concentration of the spot of the booster chlorination C0. In this text, a residual chlorine decay transfer function model composed of time series model AR (n) and main factors model is proposed. The model was tested in the system of the booster chlorination in the urban-rural water distribution of JiaXing. Thus the model proposed in this text is reasonable and effective.
