摘要
本论文研究的目的在于研究电场与生物协同作用下,SBR法去除污水中氮磷的效果。实验结果表明,电极-SBR法比传统的SBR法在脱氮除磷方面,都有比较明显的提高。实验还揭示:由于电场的作用,造成了电极表层的氧气浓度降低,抑制了硝化/亚硝化菌的生长,并在电解的过程中为反硝化提供H+作为电子受体,促进了反硝化反应。而阴极板上产生的氢气形成了缺氧环境,反硝化菌可能在缺氧的条件下利用氢作为载体对硝酸盐氮、亚硝酸盐氮进行彻底的氧化还原成氮气。
In the paper,we wanted to know the differences of the effects of wastewater treatment with sequencing batch reactor if is electrode.The experiment indicated,even through in the treatment effect of nitrogen or phosphorus,electrode-sequencing batch reactor is better than sequencing batch reactor.That the electrode reaction has created the oxygen consistency of the electrode surface level reduction and restrains the more growth nitrifying the fungus,and on the other hand electrolysis provides H＋ as the electronics reception body for nitrifies fungus,and has promoted denitrify the reaction.Hydrogen that the cathode gives has formed the anaerobic areas,and the denitrifies fungus probably is being short of the organic matter that the utilization is adsorbed under the oxygen condition and does the anti-absorb that nitrifies the capacity accomplishing opposite phosphorus of carbon source.
