摘要:为指导污水处理厂提标设计,采用GPS-X软件的MANTIS模型构建福建某污水处理厂提标工艺模型。通过不同进水温度的处理效果模拟,发现改良Bardenpho工艺脱氮效果更好。在此基础上运用模型对拟定的工艺进行优化,使改良Bardenpho工艺出水均到达到准IV 类水质标准。

Abstract: For guiding the plant design, a sewage treatment plant model at Fujian is developed based on MANTIS model of GPS-X software. By simulating the treatment effect of different temperatures, it was found that the modified Bardenpho process has better nitrogen removal performance. Then the model was used to optimize the two suggested configurations of the modified Bardenpho process to achieve the IV class surface water quality standard in the plant effluent for both nitrogen and phosphorus removal.
Key words: GPS-X; upgrading and reconstruction; nitrogen and phosphorus removal; sewage treatment plant

随着我国《水污染防治行动计划》的颁布,污水处理厂的排放标准要求提升,其面临着提标的问题。对于高排放标准的污水处理厂,采用传统简单计算方法难以满足设计要求[1; 2]。GPS-X软件是污水处理厂的规划设计、提标改造及运行管理中的有效模拟仿真工具[3-6]。为指导污水处理厂提标设计,本文应用嵌入MANTIS模型的GPS-X软件,以福建某污水处理厂为提标改造对象,通过模拟分析,拟定提标工艺方案,并在此基础上进行工艺优化模拟,提出可行的提标工艺,为基于数学模型的污水处理厂工艺优化设计提供借鉴。
