- Abstract:
- The data including the turbidity of the raw water, the turbidity of the water to be filtered, and the coagulant dosage are collected from W waterworks in the past year to establish a mathematical model of coagulant dosage and compile a PLC system program, which automatically calculates the coagulant dosage and instruct the coagulant dosage pump to work by setting the target turbidity of the water to be filtered and reading the raw water turbidity data through the PLC system, and taking the turbidity of water to be filtered as effect feedback. By establishing an automatic and accurate coagulant dosing system in the waterworks, the coagulant dosing can be controlled more accurately, the effluent quality can be stabilized, and subjective judgment errors can be reduced, which provides the possibility for the optimized operation of the waterworks to be implemented.
