味精厂废水混合二相体放电预处理的研究

Study of Pretreatment of the Waste Water of Monosodium Glutamate by Two-phase Mixture Discharge

利用荷电混合二相体 (EHD)放电预处理味精厂废水 ,观测到化学耗氧量 (COD)、氨氮 (NH3- N )升高 ,说明大量有机高分子已被高能电子破坏 ,有利于进一步生化处理。实验中研究了电压、废水流量的影响 ,与单独臭氧处理效果的比较说明放电过程中 ,高能电子。

The waste water of monosodium glutamate is pretreated by EHD discharge. COD and NH 3-N are increased after discharge. The COD variations with the pH, voltage and flux are studied. At the same time, comparing the results of discharge treatment with the one of ozone treatment, we know the action of electrons and radicals is the most important in the two-phase mixture discharge. These studies are helpful to the treatment of organic wastewater.
