The phosphorus removal system regarding the automatic determination of coagulant dosing rate using artificial intelligence

摘要

The present invention relates to a method for removing phosphorus, which is one of the nutrients that cause eutrophication in rivers, lakes, water and the like, from sewage effluent. If the concentration of phosphorus in sewage effluent can be measured in real time and the value can be immediately known, the coagulation tank chemical injection volume can be directly adjusted to obtain the optimum treatment water quality with the optimal chemical injection. Is approximately 1 hour, PO4-P can be known after 30 minutes, so the sampling and measurement should be done before analysis time to know the concentration of TP or PO4-P at the arrival of the coagulation tank. As the amount of sludge and surplus sludge discharge changes, the arrival time of the flocculation tank changes, so it is very difficult to determine the optimum amount of chemical injection in real time. In order to treat phosphorus by the present invention, the inflow flow rate, flocculation tank inflow concentration, aeration tank return sludge and excess sludge discharge amount are pre-measured to determine the injection amount of the coagulation tank chemicals and to measure the concentration of coagulation filter water phosphorus By determining the adequacy and automatically adjusting the amount of coagulant injected into the coagulation tank in real time and injecting the optimum amount of coagulant to prevent the waste of chemicals and backwash It provides an AI type cohesive filtration phosphorus removal and wastewater treatment system that minimizes the impact on phosphorus change factors such as minimization.
