Abstract

流水式海水電解装置を用い, 日本栽培漁業協会厚岸事業場の飼育排水を直接電気分解してその殺菌効果を検討した。生成次亜塩素酸濃度が0.60mg/Lのときに1分間の処理で99%, 1.28mg/Lでは99.9%以上の殺菌率が得られた。同時に紫外線殺菌装置(1.0×(10)5μW・sec/(cm)2)とオゾン殺菌装置(TROs 0.5mg/L, 1min)の殺菌率を測定したが, ともに99.99%であった。排水の一部2.0m3/hを電気分解処理し, 残りの16.5m3/hの排水と混合処理した場合, 残留塩素濃度0.5mg/L以上, 1分間の処理で99%以上の殺菌率が得られた。

The bactericidal effect of hypochlorite produced by a continuous flow electrolyzer on hatchery waste-seawater was investigated. The number of viable bacteria in the waste-seawater was reduced more than 99% when the water was treated with hypochlorite at 0.6mg/L for 1min, and over 99.9% of bacteria was reduced when treated with 1.0mg/L for 1min. In the next experiment, one part, 2.0m3/h of hatchery waste-seawater was treated with electrolyzer and produced hypochlorite was mixed with the remaining, 16.5m3/h waste-seawater. More than 99% of viable bacterial was reduced after treatment with 0.5mg/L of total residual chlorine for 1min. The bactericidal efficacy of electrolysis was almost the same as that of ultraviolet irradiation (1.0×(10)5μW·sec/(cm)2) or ozonization (TROs 0.5mg/L, 1min) of seawater. Electrolyzation is able to treat a large volume of waste seawater compared with the ultraviolet irradiation or ozonization.
