摘要:

在北美、欧洲、南非等国度和地域, 污水处置工艺摹拟已普遍利用在污水处置的开辟、设想、提标革新和优化运转治理等方面，成为污水处置行业的尺度实践。在国内，污水处置工艺摹拟利用起步较晚，正处在成长阶段。利用工艺摹拟手艺对污水处置厂进行治理，一方面能够年夜年夜提高运营治理程度；另外一方面也可为实现聪明化水厂奠基根本。以东莞年夜岭山连马污水处置厂作为示范，成立并校订了该污水处置厂的工艺模子，利用模子对污水处置厂运转近况进行体检，寻觅鸿沟运转前提。成果注解，在设想流量前提下的运转进程中，当MLSS低在3 000 mg/L、进水TN高在20 mg/L时，出水氨氮有超标风险；当进水TN到达36 mg/L时，若要包管出水水质不变达标，COD必需年夜在200 mg/L，当MLSS为6 000 mg/L时，最年夜处置水量为8.5×104 m^3/d。

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����app 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 m^3/d.
