本文对液膜法处理β萘磺酸钠工业废水中的废乳进行低压电破乳试验。研究了破乳温度、时间、电压以及液膜体系对破乳效果的影响。结果表明：对本实验所采用的液膜体系当破乳温度为 ５０℃～６０℃、时间 ２５ｍ ｉｎ、电压 １８０～２００ Ｖ 时，破乳效果较好，且破乳后的油相可多次重复使用，该法具有一定的实用价值。
In this paper, liquid membrane treatment of β-naphthalene sodium industrial wastewater waste low-voltage emulsion breaking test. The effects of demulsification temperature, time, voltage and liquid membrane system on the demulsification effect were studied. The results show that when the emulsion breaking temperature is 50 ℃ ~ 60 ℃, the time is 25m in, the voltage is 180 ~ 200 V, the emulsion breaking effect is good and the oil phase after demulsification can be repeated many times Use, the law has a certain practical value.
