Abstract

The disclosure proposes a system and method for automatic control of valves to minimize the rainfall pollution by real time optimizing based on multiple sensor data. There is an analysis engine for the pollution cost evaluation based on different data resources (e.g. real time sensor data). And there is an optimization engine producing the optimized plan for controlling the valves of pipes to minimize the total rainfall pollution. The valve control plan is based on the prediction of variable rainfall and water pollution, and is continuously improved by the real time sensor data transmitted by wireless communications.

System and Method for automatic control of valves to minimize the pollution of the combined sewer overflow

   Combined sewer overflow events occur when a municipality dumps untreated water from combined storm and sanitary sewer flows into a river/stream. This kind of pollution is one of the main pollutions in the city. So an optimal control system is needed to minimize the pollutions.

In the prior art, we used:


1. Sewer separation;


2. Expansion of WWTP;


3. Off-line Storage Tunnels or detention basin;


4. Distributed monitoring and control system


But the control is manually,not real time, not effective. As we want to reduce the pollution, the important factor - pollution cost is not considered. And pollution cost

is varying as the rainfall going on.

Now, we have different sensors to collect many different data that can be used. Our invention is a system and method for automatic control of valves to minimize the rainfall pollution by real time optimizing based on multiple sensor data. There are two important parts in our system. One is an analysis engine for the pollution cost evaluation based on different data resources (e.g. real time sensor data); another is optimization engine producing the optimized plan for controlling the valves of pipes to minimize the total rainfall pollution. The valve control plan is based on the prediction of variable rainfall and water pollution, and is continuously improved by the real time sensor data transmitted by wireless communicati...
