本发明的目的、 优点和特点， 将通过下面优先实施例的非限制性说明进行图示和 解释， 这些实施例是参照附图仅作为例子给出的。 附图说明
图 1为本发明工艺示意图；
图 2为本发明装置示意图；
图 3为光化学氧化与还原管的表面结构示意图。 具体实施方式
如图 1、 图 2所示， 本发明饮用水的三合一处理装置， 它包括有原水贮水桶 1、粗 滤罐 2、碳滤罐 3、精滤罐 4、水管 5、 阀 6， 它还包括有活性氧发生器 7、活性氧混合 器 8、 紫外光发生器 9、 光化学氧化与还原管 10、 陶磁超滤器 11， 活性氧发生器 7通 过管道与活性氧混合器 8麵； 活性氧混合器 8—端通过管道与精滤罐 4舰， 另一 端与光化学氧化与还原管 10连通； 光化学氧化与还原管 10设在紫外光发生器 9发出 的光源区域内； 光化学氧化与还原管 10与陶磁超滤器 11连通， 活性氧混合器 8为混 合泵（型号 USESE 20 QY2. 5)。 原水经过泵泵入原水贮水桶 1， 再通过水管 5依序经过 粗滤罐 2、碳滤罐 3、精滤罐 4完成水的前处理工序； 经过前处理的水再 ¾Λ 性氧混 合器 8， 此时活性氧发生器 7发生出的活性氧 (03)也进入活性氧混合器 8与水一起进 行混合， 其活性氧的加入量为每升原水 l_4mg/l， 原水的温度为 15°C- 30°C， 原水的压 力为 1- 3kgf/cm2 ; 完成活性氧与水混合工序； 经过混合的水进入光化学氧化与还原管 10 , 在紫外光发生器 9 的作用下， 其光能的激发能量为 90-140kcal/mol 或 376- 585k j/mol， 在此工序中， 上道工序中加入的活性氧在水中进行厌氧反应， 清除水 中的厌氧菌， 同时紫外光 (UV)对水进一步杀菌， 并加强了活性氧的氧化与还原功能， 使光化学氧化与还原反应更为彻底； 完成光化学氧化与还原工序的水经过水管进入陶 磁超滤器 11中， 陶磁膜超滤工序设在光化学氧化与还原工序前， 其内陶磁滤膜 12的 空径为 0. 0卜 0. 5μηι， 由于使用了本陶磁超滤膜， 光化学氧化与还原工序中 UV杀菌后 遗留的细菌尸体被过滤， 使流出的水口感好， 并减少了二次污染的机会。 陶磁超滤膜 将 03还原后的有机和无机污染物以还原后的固体形式滤除， 也使出水口感较好， 并减 少了污染物对人体的伤害； 陶磁超滤膜 12将 UV及 03不能完全杀灭的细菌与病毒完全 滤出。
为了起到更好的应用效果、 产生更多的负离子， 本发明饮用水的三合一处理装置 当中， 可以在光化学氧化与还原管 10 的远离光源辐射的管壁外侧涂覆高分子陶瓷层 13， 如图 3所示。 当光化学氧化与还原管 10是多层绕在一起使用时， 只需在最外层的 管壁外侧涂覆高分子陶瓷层 13； 若光化学氧化与还原管 10是单层使用， 则高分子陶 瓷层 13应当涂覆在远离光源辐射的管壁外侧。 这里， 高分子陶瓷层 13可以由聚酯 (polyester, PET)树脂或者聚乙烯（polyethylene, PE)树脂与平均粒径低于 lOOnm 的电气石或者麦饭石混合而成， 其中聚合物树脂的重量含量为 50-70%， 电气石或者 麦饭石的重量含量为 30-50% ;较为理想的重量配比是聚合物树脂占 2/3、电气石或者 麦饭石占 1/3。
在本装置使用一段时间后， 可以利用反冲洗系统对陶磁超滤器进行反冲洗， 其反 冲压力为 2- 4kgf/cra2。 由于前述工序的联合使用， 使 96%以上的水中有机污染物变成 了碳、水、氧、二氧化碳和 0H―，附着在陶磁膜上被阻隔的有机污染物还原物成为固体， 因而改变了水中的有机污染物使其丧失粘着力与团聚力， 因而在对陶磁超滤膜进行反 冲洗时， 可轻易地将该被还原固体物排出陶磁超滤器外， 解决了高密度陶磁膜极易堵 塞而无法商业应用的难题。
除上述实施例外， 本发明还可以有其它实施方式。 凡采用等同替换或等效变换形 成的技术方案， 均落在本发明要求保护的范围之内。
