摘　　要：高压脉冲放电技术具有开发费用低、无二次污染等优点。本文考察了多种因素对高压脉冲放电技术去除污水中氮磷的影响。结果表明,最优脉冲放电条件为:峰值电压10kV,频率70Hz,脉冲时间25min,电极间距2cm。在最优脉冲条件下去除污水中氨氮和正磷酸盐,去除率分别为38.35%和28.96%。研究说明高压脉冲放电技术是污水脱氮除磷潜在的有效途径。The high-voltage pulse discharge technology has the advantages of low development cost and no secondary pollution.This paper has investigated the effects of various factors on the removal of ammonia nitrogen and orthophosphate from wastewater by high voltage pulse discharge technology.Results showed that the optimal pulse discharge conditions: peak voltage 10kV,frequency 70Hz,pulse time 25min,electrode spacing 2cm.The ammonia nitrogen and orthophosphate in the sewage were removed under the optimum pulse conditions,and the removal rates were 38.35% and 28.96%,respectively.Studies have shown that high voltage pulse discharge technology is an effective way to remove ammonia nitrogen and orthophosphate from sewage.
