电解脱氮除磷技术在海产养殖废水治理中的研究

海产养殖迅速发展造成水域富营养化、赤潮频发,海产养殖废水污染的治理迫在眉睫。为解决此问题将电解脱氮除磷技术应用在海产养殖废水处理中,并探讨电压、pH、极板间距和电解时间对脱氮除磷去除率的影响。结果表明:脱氮除磷的去除率与电压成正相关,与极板间距成负相关。在电压为30V,极板间距10cm,pH为7时,NH_4~+-N、NO_3~--N和TP的去除率达到最大分别为72%、90%、85%。

A study on electrolysis technology for nitrogen and phosphorus removal in wastewater treatment of aquaculture

The rapid development of aquaculture causes eutrophication and frequent occurrence of red tide in the waters.The wastewater pollution treatment of aquaculture has become the most urgent problem.In or-der to solve this problem,electrolysis technology for nitrogen and phosphorus removal is applied in the wastewater treatment of aquaculture.The paper discussed the effect of different factors including applied voltage,pH,space between the electrodes and electrolytic time on the removal rate of nitrogen and phos-phorus.The results indicated that the removal rate of nitrogen and phosphorus is positively correlated with voltage,and is negatively correlated with the space between the counter electrodes.The removal efficiency for NH +4-N、NO -3-N and TP reach the maximum of 72%,90% and 85% respectively while the voltage is 30V,the space between the electrodes is 10cm,and the pH value is 7.
