Abstract
An electrolytic drainage treating apparatus is provided to treat a drainage containing a suspension of contaminated compound whereby the suspension is flocculated and removed by aluminum ions or iron ions eluted by electrolysis. The electrolytic drainage treating apparatus is equipped with a high speed electrolyzer comprising an anode and a cathode having a thin gap therebetween through which a drainage is forcibly passed as an electrolytic solution. The anode material such as aluminum and iron is eluted as ions by the electrolysis caused by passing electric current across the gap. The width of the gap between the anode and the cathode is controlled. The high speed electrolyzer is effectively used for various electrolytic treatments.

An electrolytic drainage treating apparatus comprising:
- a high speed electrolyzer comprising an anode and a cathode with a thin gap therebetween,
- means for forcibly passing at a high velocity a drainage as an electrolytic solution through said gap,
- means for eluting the anode material as ions,
- the gap being thin enough and the velocity being high enough to wash out materials formed between the electrodes by the electrolysis,
- the gap being less than 1 mm.,
- whereby contaminated materials in the drainage are flocculated by the ions.
An electrolytic drainage treating apparatus comprising:
- a high speed electrolyzer comprising an anode and a cathode with a thin gap therebetween,
- means for forcibly passing at a high velocity a drainage as an electrolytic solution through said gap,
- means for eluting the anode material as ions,
- the gap being thin enough and the velocity being high enough to wash out material formed between the electrodes by the electrolysis,
- a spacer made of an electric insulator mounted on the cathode surface to make contact with the anode surface so that scale formed on the anode surface can be removed by movement of the spacer with respect to the anode surface,
- whereby contaminated materials in the drainage are flocculated by the ions.
An electrolytic drainage treating apparatus equipped with a high speed electrolyzer comprising:
- an insulator plate mounted on bottom of the electrolyzer;
- an anode placed on the insulator plate;
- a cathode disposed next to the anode with a thin gap therebetween;
- a holder mounted on the cathode on the surface opposite to the anode through an insulator plate;
- a motor for turning the holder;
- a spacer mounted on the cathode surface opposite the anode so as to slide on the anode surface;
- and
- means for forcibly passing a drainage through the gap.
