摘要

Real time control (RTC) of sewer systems has been proven to be a cost-effective solution for reducing the qualitative impacts of both combined sewer overflow discharges into the receiving water bodies and shock loads to the treatment plant. In this paper the improvement of the performance of a quality-oriented CSO device by the application of RTC techniques to moveable gates is evaluated in terms of reduction of discharged volumes and pollutants. The potential benefits of RTC in terms of increase of water volumes and pollutant masses conveyed to the treatment plant have also been investigated. For these objectives a local control strategy based on the activation of the maximum in-line storage capacity has been adopted. The analysis has been carried out using a numerical model specifically developed for RTC applications. The implemented model is based on the fully-dynamic St. Venant equations for the flow and on the advection-dispersion equation for the analysis of pollutants in the sewer system. Simulations have been run with the quantitative and qualitative experimental data measured, during several rain events, in two Italian urban catchments, Cascina Scala (Pavia) and Fossolo (Bologna). The benefits of the introduction of the real time control have been evaluated separately by comparing the results of RTC scenarios (with one and two controlled gates) with the results obtained in the no-control scenario. Globally, in spite of the good performance of the adopted CSO device, the results of the simulations show remarkable advantages in terms of reduction of CSO discharges obtained with the RTC of one moveable sluice gate and the additional benefits provided by the introduction of the second gate. An appreciable increase of the total volume conveyed to the treatment plant is also obtained without exceeding the maximum treatment capacity.
