瘦西湖风光电能驱动的曝气生物接触氧化水净化系统结构与功能

在瘦西湖选择中试河段,利用太阳能风能绿色能源,研发了风光电能驱动的曝气生物接触氧化水净化系统。系统由风光互补发电子系统、曝气生物接触氧化子系统、植物生态子系统组成。风光电能驱动的曝气生物接触氧化水净化系统运行正常。按照景观娱乐用水水质标准进行水质监测,采用模糊综合评价与贴近度计算方法,进行了系统水净化功能评价。结果表明,在试验段原水水质低于景观水C类,经该系统水净化后,可以达到景观水B类。系统的开发与实验,探索了利用绿色能源河湖水净化的新途径。

Structure and functioning of a aerated water treatment system powered by photovoltaic/wind energy in Slender West Lake

A pilot photovoltaic/wind driven water treatment system was set up near Slender West Lake in southeastern China.The system has three central components,the photovoltaic/wind hybrid generation system,the biological oxidation treatment system and plant biological subsystem.The hybrid(photovoltaic/wind) system provides energy for the aeration treatment system in a good condition.During the pilot tests,the water quality was monitored and compared to the water quality standards.The water treatment efficiency was evaluated using Fuzzy integrative assessment and a proximity computation method.The data showed that water quality in the test river section was below Class C.After treatment,the water quality reached Class B,meeting the standard for scenic and recreation areas.The development and testing of the hybrid treatment system illustrates a new approach to treating poor quality waters using green energy.
