Application of Intelligent Phosphorus Removal Dosing System in Water Treatment
A sewage treatment plant in Guangdong,which treats 100,000 tons of sewage per day,began using an intelligent phosphorus removal and dosing system in August 2021.The operation data of more than two years show that 100％of the total phosphorus in the effluent reaches the first-class A discharge standard,that is,the effluent TP concentration is less than 0.5 mg/L,and the system runs stably.Since the system was put into production,the phosphorus removal agent has been reduced by more than 33％,saving the cost and recovering the system construction cost.After the system was built and put into use,the fluctuation range of COD and ammonia nitrogen data in the effluent decreased from the original maximum of 20％and 26％to 14.8％and 18.5％,indicating that the intelligent phosphorus removal and dosing system can not only save the amount of chemicals added,but also play an important role in ensuring the stability of the effluent.
