The purpose of this study is to investigate into the electrolytic treatment of polyvinyl alcohol wastewater. In order to remove PVA from wastewater by electrolytic treatment. Fe electrode was used as a soluble electrode for this study. The results are summarized as follows : 1. PVA was removed nearly to 100% as the value of ampere hour concentration was more than 0.5 Ahr/ℓ. 2. Regardless of the initial pH of wastewater, the pH of wastewater after electrolytic treatment was among 10 and 11. So, it is necessary to neutralize the treated water. 3. PVA was removed quickly as the current density was rised, the electrode distance was approached, NaCl was added and the initial pH of wastewater was above 7.
