- Abstract:
- An intelligent control system based on chemical phosphorus removal model and on?line sensor was applied to optimize the dosage of chemicals in a wastewater treatment plant, so as to make the effluent total phosphorus meeting the first level A discharge standard. The control strategy of an intelligent control system for chemical phosphorus removal was designed in a wastewater treatment plant in Guangzhou, and the formula of chemical phosphorus removal was fitted to characterize the performance of the intelligent phosphorus removal system. When treating domestic sewage with average total phosphorus, the dosage of phosphorus removal chemical could be saved by 40%-50%, and the construction cost of the control system could be recovered within 2-3 years. After adopting the intelligent control system for chemical phosphorus removal in the wastewater treatment plant, the goal of dosage reduction was realized on the premise that the effluent quality reached the discharge standard stably.
