摘要
在现有研究成果的基础上,考虑我国的污水处理特点,强调监管部门提出的节能降耗要求,给出了一套新的控制策略性能综合评价指标体系。该指标体系由目标层、变量层和指标层构成,指标层为最底层,含有9个可量化的指标,分别为达标因子、超标因子、能耗因子、物耗因子、受控变量追踪失败因子、操作频繁因子、操作幅度因子、出水峰值因子、出水波动因子。给出了单个指标计算方法以及性能评价综合指数计算方法。以曝气单元的DO末端控制和沿程控制策略评价比较为例,对该指标体系进行了案例应用,证明了该指标体系的实用性和可操作性。
In the paper, taking account of the Chinese characteristics of wastewater treatment and the requirements of energy saving and consumption reduction from Chinese government, a new indicator system has been established for performance evaluation of wastewater treatment unit control strategies. The evaluation indicator system consists of three levels, aim, variable and indicator level. The indicator level is the bottom level, which includes 9 quantitative indicators, such as standard compliance index, standard incompliance index, energy cost index, chemical consumption index, controlled variable track failure index, manipulation frequency index, manipulation range index, effluent peak index, and effluent flocculation index. The calculation method of each index and the integration method of the performance index have been brought forward. The indicator system has been applied to evaluate aeration end control and along control strategies, and the results have shown the feasibility and practicability of the indicator system.
