    • Conventional purification apparatuses and operation methods therefor require continuous addition of coagulants as expendables in every operation, and the coagulants are expensive, thereby causing increase in operation cost, and furthermore, the operators have to convey and resupply the coagulant at regular intervals which further increases the operation cost owing to the personnel cost to be increased accordingly. The invention provides a purification apparatus and an operation method therefor, for coagulating and separating particularly the pollutant matter in sea water including oil and the like, which can regenerate and reuse the coagulant within the apparatus, without scarcely resupplying the coagulant and acid/alkali solutions. For disintegrating coagulated flocs and regenerating the coagulant from the sludge, a strong alkali solution and a strong acid solution are required. According to the invention, an alkali water enriched in sodium hydroxide and an acidic aqueous solution containing hydrochloric acid and the like are generated by electrolyzing sea water and collecting sodium ion and chloride ion respectively in the cathode and anode sections, and also by including hydroxide ion and hydrogen ion in sea water; the flocs in the sludge are disintegrated by use of the alkali water; pollutant matter is removed from the aqueous solution subjected to disintegration; and the strongly acidic solution containing hydrochloric acid is added to the acidic solution from which pollutant matter has been separated and removed, and a ferric chloride aqueous solution is generated. The ferric chloride aqueous solution is the coagulant, and thereby the coagulant can be regenerated from the recovered sludge.
    • 常规的净化装置及其操作方法需要在每个操作中连续添加凝结剂作为消耗品,并且凝结剂昂贵,从而导致操作成本的增加,此外,操作者必须以规则的间隔输送和补充凝结剂,这进一步增加 运营成本由于人员成本相应增加。 本发明提供了一种净化装置及其操作方法,特别是在包括油等的海水中的污染物质的凝结和分离,其可以在设备内再生和再利用凝结剂,而几乎不再提供凝结剂和酸/碱溶液 。 为了分解凝结的絮凝物并从污泥中再生凝结剂,需要强碱溶液和强酸溶液。 根据本发明,通过电解海水并分别在阴极和阳极部分收集钠离子和氯离子,并且还包括氢氧化物离子,产生富含氢氧化钠的碱性水和含有盐酸的酸性水溶液 海水中的氢离子; 污泥中的絮状物通过使用碱水分解; 从分解的水溶液中除去污染物质; 将含有盐酸的强酸性溶液加入已经分离除去污染物质的酸性溶液中,生成氯化铁水溶液。 氯化铁水溶液是凝结剂,从而可以从回收的污泥再生凝结剂。
