摘要
针对序批式反应器污水处理工艺,提出一种以排水质量指标为约束条件,以能量消耗最小为目标的最优控制方案.由于生化过程机理复杂,导致这个最优问题求解困难.所构造的解法是首先建立通用的序批式反应器模型;然后借助仿真工具试差求取次优解.为解决搜索求解计算量大的问题,进一步结合进退法提出了一种改进的优化算法,显著提高了求解效率.
An optimal control scheme for sequencing batch reactor (SBR) wastewater treatment processes is proposed to achieve the wastewater effluent standards with minimal energy consumption. Because of the complex mechanism in biological processes, it is difficult to solve this optimization problem. The constructed solving process is to establish a general SBR model firstly, then to derive the suboptimum solution by trial and error method with the help of simulation tools. To solve the problem of large search solution computation, an improved optimization algorithm is proposed based on the thought of advance-retreat method, and it raises the solution efficiency significantly.
