摘要：

在正交实验和单因素实验的基础上，对非平衡等离子体水处理反应器的整体结构进行了优化设计，并对优化后反应器的性能进行了定性评价。正交实验结果表明，影响降解效率的因素为气高、液高和气体流量。针高度为4mm、电极间距为17mm、气体流量为96L·h^-1时甲基橙的降解效果最佳。用40目不锈钢网作地电极，采用正脉冲放电能提高降解效率，预处理溶液中放置不锈钢阻挡网有助于提高臭氧的利用率。降解效率和COD去除率随溶液初始浓度的增加而降低，但相同时间内有机污染物的绝对去除量增加，重复实验表明实验误差小于3.5%。

Abstract:

The monolithic construction of the non-equilibrium plasma reactor is optimized and the performance of the reactor was estimated on the basis of orthogonal and single factor experiments. The experimental results show that the primary and secondary factor influencing degradation efficiency is the height of air layer, the height of aqueous solution and the gas flow, respectively. The best result is obtained when the needles length in water is 5mm, the electrode gap is 17mm and the gas flow is 96L•h^-1. The degradation efficiency can be improved when positive pulse was applied to the high voltage electrode and the ground electrode was made of stainless steel mesh with mesh size of 0.42mm. The design, fixed the stainless steel mesh barriers in the solution for pretreatment, increases the utilization factor of ozone. Although the degradation efficiency and COD removal are decreased with the increase of initial solution concentration, the absolute conversion amount of organic contamination increases in the same time. The repeated tests indicate that the experiment error is less than 3.5%.
