The results show that the regression equation relating to effluent BOD5,cubage load (Nv),temperature (t) and addition dosage (ρ) is BOD5=2.05Nv-0.41t-0.82ρ+38.9. The orthogonal experiment results of constructed wetland post-treatment show that the regression equation relating to effluent BOD5,cubage load (NA),and temperature (t) is BOD5=1 190NA-0.32t+12.2. Based on the two orthogonal regression equations,combined of green building municipal gray reclaimed water quantity requirements in different seasons,a technology investment on economic optimization model of combinational technique was established. The results offer technological support for reclaimed water treatment,which regards superior drainage as the source and is purified by combinational technique of coagulation sedimentation and constructed wetland. According to the model,the reasonable scale of reclaimed water treatment systems can be determined,the treatment efficacy can be well predicted,and both the design and operating can be effectively guided.展开更多

文摘兼顾电源侧多能互补与负荷侧需求响应(demand response,DR)是提升源荷侧协调发电能力的重要手段,可以促进电力削峰填谷,提高经济效益。针对冷、热、电负荷需求的随机性和不匹配性,考虑到人体对温度有一定的适应能力,文章将风、光发电机组与燃气轮机冷热电联产(combined cooling,heating and power,CCHP)系统结合,提出了一种基于综合需求响应的源荷协调CCHP微网,同时采用典型场景集考虑新能源出力的不确定性,建立优化调度模型。该模型以最小化系统经济成本为目标,利用免疫遗传算法求解,探讨了系统经济调度成本与不同需求响应模式以及温度偏差的关系,并对系统是否引入电加热设备进行讨论。算例分析表明,基于需求响应和多能互补的CCHP微网优化调度方法,能有效降低综合运行成本,具有显著的经济及社会价值。
