- Abstract:
- In North America, Europe, South Africa and other regions, wastewater treatment process simulation has been widely used in the development, design, upgrading and optimization of wastewater treatment plants (WWTPs) management, and has become a standard practice in the wastewater treatment industry. In China, the simulation of wastewater treatment process started late and is in the development stage. On the one hand, the application of process simulation technology to the management of WWTPs can greatly improve the level of operational management. On the other hand, it can also lay a foundation for intelligent WWTPs. A process model of Dalingshan Lianma WWTP in Dongguan City, Guangdong was set up and calibrated. The calibrated model was then used to analyze the operation of the process and find boundary operational conditions. When MLSS was lower than 3 000 mg/L and total nitrogen of influent was higher than 20 mg/L under the design flow rate, ammonia nitrogen in the effluent had the risk of exceeding the standard. When the total nitrogen of influent reached 36 mg/L, COD must be greater than 200 mg/L so as to meet the effluent standards, when MLSS was 6 000 mg/L, the maximum treatment capacity was 8.5×104 m3/d.
