摘要:

针对我国寒带地区冬季污水处理厂因原生污水水温过低导致生化反应效果下降的问题,以污水热泵提热循环系统模型为基础,针对热源侧变流量控制方案,提出了一种基于自适应权重粒子群优化(PSO)算法的变频控制策略。以东北某城市污水处理厂为原型,以系统年运行能耗最低为目标,优化了全年不同原生污水温度下热源侧的污水泵频率。通过对该系统变流量控制和定流量控制两种不同控制方案进行模拟运行,仿真验证了本文算法的有效性。

Abstract:

To address the issue of reduced biochemical reaction efficiency in wastewater treatment plants located in frigid zones of China during winter, caused by excessively low temperatures of raw sewage, a variable-frequency control strategy based on an adaptive weight particle swarm optimization (PSO) algorithm was proposed. Using a wastewater treatment plant in a northeastern Chinese city as a prototype, with the goal of lowest annual operating energy consumption of the system, the frequency of the sewage pump on the heat source side was optimized for different raw sewage temperatures throughout the year. Simulation runs comparing this system's variable flow rate control scheme with constant flow rate control scheme were conducted. The simulation results demonstrated the effectiveness of the proposed algorithm.

Key words: environmental engineering, sewage heat pump, TRNSYS, particle swarm optimization algorithm, energy consumption analysis
