摘　　要：基于微电极结构,采用阵列式电极排布形式,设计了气-液放电装置,并开展了绿藻类生物废水处理研究.实验讨论了放电功率、处理时间以及初始浓度等要素对绿藻失活效率的影响.研究结果表明气-液放电对水中绿藻类生物有较好的杀灭效果.其中,绿藻失活效率随放电功率和放电时间的增加而明显增强;绿藻失活效率随废水中绿藻初始浓度的升高而急剧降低.紫外可见吸收光谱检测结果分析表明放电过程中产生的H_(2)O_(2)含量对绿藻致死过程起到关键性影响.Adopting the array electrode arrangement,the gas-liquid discharge device was designed based on the micro-electrade structure,and the research on the treatment of green algae biological wastewater was carried out.The influence of discharge power,treatment time and initial concentration on the inactivation efficiency of green algae were discussed.The results showed that gas-liquid discharge had a good killing effect on green algae.The inactivation efficiency of green algae increased significantly with the increase of discharge power and discharge time,and decreased sharply with the increase of its initial concentration.The results of UV-VIS absorption spectroscopy showed that the content of H_(2)O_(2) produced during the discharge process played a key role in the lethal process of green algae.
