The invention has a plurality of innovations that bipolar membrane energy-saving dissociation molecules are inserted between electrolytic cells to supply OH to produce .HO, lead-free tin oxide semiconductor electrode is supplied for a cavity (h+) without lead to pollute water body, and a dual-liquid stream structure is used so that the concentration of .HO is never saturated.
