三维电极-电Fenton耦合法处理乳化含油废水

Gongye shui chuli
机加工产生的乳化含油废水中有机物成分复杂，可生化性差，采用纳米零价铁、活性炭及玻璃珠混合颗粒作为粒子电极，构建三维电极-电Fenton耦合工艺体系对其进行处理。考察阴极板材料、粒子电极投加比、电压、pH、极板间距、曝气量等因素对乳化含油废水总油、COD去除效果的影响。结果表明，pH、极板间距、曝气量、电压是主要影响因子，影响程度排序为pH>极板间距>曝气量>电压。采用三维电极-电Fenton体系处理COD 1 030 mg/L、总油质量浓度约为150 mg/L的乳化含油废水 ...

电压——频率变换器

, 1986
电压--频率变换器,它具有一个由差分放大器构成的积分器,一个电平可控脉冲发生器,一个开关控制器和一个精密电荷分配器.该精密电荷分配器是由三个开关,一个定电荷电容,一个参考稳压管,一个充电电阻及一个负电源组成的.该定电荷电容放完电后,通过上述充电电阻,在上述差分放大器的反相输入端和上述负电源之间积分充电到上述参考稳压管的击穿电平而完成定电荷的.较之已有的积分定电荷反馈复原型电压--频率变换器的定电荷方式优越,提高了变换器的精度,稳定性和高频性能 ...
