<p>PROBLEM TO BE SOLVED: To provide a new method for purification treatment of livestock waste-liquid, in which chemicals such as a floccurant are not used, organic components increasing BOD, COD, nitrogen, phosphorus, coloring components, malodorous components are efficiently removed continuously in a short time. SOLUTION: Livestock waste-liquid is aerated in an aeration tank in which aeration microorganisms exist, then supplied to an electrolytic device in which electrodes comprising a platinum group metal on the surface is provided, and interelectrode distance is held to be at least 3 mm, and a reticulated spacer is placed between the electrodes so as to cause turbulent in the liquid flowing between the electrodes.</p> |
