本发明是对医疗设施、工厂、一般家庭、商店及多人聚集地公共场所等所排出的废水进行处理的废水处理装置。
背景技术
近年来,由于环境意识的提高而对医疗设施、工厂、一般家庭、商店及多人聚集地公共场所等所排出的废水应该进行适当处理的要求也在提高。如果部将这一类的废水进行处理而直接排入下水道,不仅会增加公共处理设施的压力,还会对下水道或者周边的地基产生污染累积,而对生活环境产生不良影响。例如:在医疗设施等机构一直以来都是通过废水处理装置将医疗废水进行处理后,使之达到净化的状态再排入下水道的处理方法(参见下述的专利文献1)。
然而,原来的废水处理装置则难以满足近年来所提出的环境标准,现在正在研究是否不让上述的废水流入下水道而是积存在积存设备内,在积存到某一定的量时再由专业机构回收,通过专门的设施进行整体处理等方法。
专利文献1:日本专利特开平4-87678号公报。
然而,如果将上述废水大量积聚然后进行整体处理的话,必须备有这个量所需的大型的处理设施。另外,还考虑到行政方面也必须准备这样的设施,并且,如果构筑这样的社会性的废水设施会对这些废水排除机构或个人增加很大的废水处理费用的负担。
发明内容
鉴于上述事项,本发明的目的是提供一种不仅是医疗设施所排出的废水,就连一般的工厂、家庭、商店及多人聚集地公共场所等所排出的废水也能净化到能够达到下水道排放标准的能够进行废水处理的装置。
本发明所述的废水处理装置具有积存需处理废水的废水积存槽,及加热前述的由前述的废水槽供给的前述的废水的燃烧釜,与收集前述的燃烧釜所发生的粉尘用的集尘装置和前述的冷却燃烧釜中产生的蒸汽所用的冷风装置,通过前述的冷风装置所冷却的蒸汽进行气体和液体分离的气液分离装置、将通过前述的气液分离装置分离出来的液体进行净化的液体净化装置等。前述的液体净化装置中使用了白金触媒使之发生臭氧、就是通过这个臭氧将前述的液体进行净化。
本发明所述的废水处理装置具有积存所需处理的废水,即将医疗设施、工厂、一般家庭、商店及多人聚集地公共场所等所排出的废水进行处理的废水积存在废水槽暂时积存,并提供给燃烧釜。将提供给燃烧釜的废水进行加热至使之水分蒸发。在加热过程中加热釜中所发生的粉尘通过集尘装置进行集尘。在燃烧釜中所发生的粉尘通过集尘装置进行收集。在燃烧釜中所发生的蒸汽通过冷风装置冷却后供给气液分离装置。供给气液分离装置的所分离的气体和液体中的蒸汽被分离为气体与液体。通过气液分离装置所分离的液体供给液体净化装置,利用白金触媒使之产生臭氧,这样的净化方法可达到流入下水道也不会发生问题的水平。
本发明的废水处理装置也可以装备通过前述的气液分离装置将前述的液体与前述的被分离的前述的气体用前述的燃烧釜的热量进行燃烧的次级燃烧装置。
在本发明的废水处理装置中,将通过前述的气液分离装置所分离的气体利用燃烧釜的热量进行二次燃烧,通过这个方法将该气体中残留的气体成分进行分解。因此,即使将燃烧后的气体排放到大气中也不会有臭气,这样就不会招致装置周围的人们的抱怨。
本发明的废水处理装置在前述的废水槽设置监控水量的水量传感器,通过前述的水量传感器判断前述的废水槽的水量已经达到规定水量时即可将前述的槽内的废水提供给前述的燃烧釜。
在前述的废水处理装置中,当废水槽的水量达到规定的量时,就会将废水槽内部的废水提供给燃烧釜。因此,废水槽内的废水不会溢出,这样就可维持装置周围的清洁。
采用本发明即可对医疗设施、工厂、一般家庭、商店及多人聚集地公共场所等所排出的废水进行处理的废水进行净化处理。所处理的废水即使排放到下水道也不会有问题,达到了净化标准,因此需排水的团体或个人还可以个别地进行废水处理。

具体实施方式
以下,就本发明的废水处理装置的第1实施形态、参照图1进行详细说明。
本实施形态的废水处理装置为医疗设施中用于处理治疗所发生的废水的装置。这个废水处理装置具有图1所示的废水槽1与燃烧釜2、集尘装置3、风冷***4与气液分离装置5、二次燃烧装置6与液体净化装置7。
废水槽1为医疗设施中用于处理治疗所发生的废水的积存装置。在废水槽1的内部设置有将积存于废水槽1的废水提供给燃烧釜2的泵1A与废水槽1内部进行脱臭及杀菌的光触媒脱臭除菌装置1B。光触媒除臭杀菌装置1B上装有涂上了二氧化钛的网和紫外线灯,在废水槽1的内部对液体、液面、各装置的内壁面及液面上产生的气体发挥了杀菌和脱臭的效果。另外,在废水槽1的内部设置有高位和低位的2个水位传感器。
在泵1A与燃烧釜2之间配设的水管上设置有电动阀1C。电动阀1C与泵1A联动动作,这样可防止废水向废水槽1的倒流或废水向燃烧釜2的过供给。
燃烧釜2是一种将从废水槽1供给到燃烧釜2的废水加热并将这个废水杀菌和脱臭的同时,还具有降低有机物功能的设备。燃烧釜2是由将废水槽输送过来的废水进行燃烧的燃烧室与将燃烧室进行加热的加热室所构成,燃烧室和加热室均为密封结构。
在燃烧室中设置有将废水进行均匀的加热,并将废水所发生的臭气保持在一定状态的搅拌机构2A,与驱动搅拌机构2A的电动机2B。在加热室中设置有用于加热燃烧室的加热器和温度传感器。作为燃烧釜的加热方式不仅限于加热器,也可采用通过气体(LPG等)的燃烧加热的方式,如有IH加热方式也可。
集尘装置3为将燃烧釜内部搅拌废水或加热时析出的物质(以下称为粉尘)燃烧釜回收的装置。集尘装置3是由向燃烧釜2吹入空气的鼓风机3A与回收燃烧釜2内部的粉尘的真空装置3B构成。在燃烧釜2与集尘装置3之间配设的管道上设置有电动阀3C(或电动球阀)。电动阀3C与集尘装置3联动动作,可防止粉尘燃烧釜2的倒流。
风冷***4为将从燃烧釜2所排出的蒸汽冷却的装置。风冷***4由回收蒸汽所含热量的热交换器与蒋换热器所回收的热量发散的散热器所构成。在燃烧釜2与冷风装置4之间配设的管道上设置有电动阀4A(或电动球阀)。电动阀4A可防止蒸汽以外的物质(例如吹入燃烧釜2的空气或伴随而来的粉尘)流入风冷***4。
气液分离装置5为将从燃烧釜2经由风冷***4导入的蒸汽进行液体和气体的分离的装置。在气液分离装置5中内置粒径为3微米到7微米左右,最好为5微米左右的活性炭过滤器。在气液分离装置5中与液体分离的气体被引导到二次燃烧装置6。另外,在气液分离装置5中与气体分离后的液体被引导到液体净化装置7。
二次燃烧装置6为将气液分离装置5中与液体分离的气体加热并将气体中所含的臭气成分分解的装置。二次燃烧装置6以燃烧釜2作为热源进行动作。
液体净化装置7是将气液分离装置5中与气体分离的液体用臭氧气体进行净化的装置。液体净化装置7由使用白金触媒使之发生臭氧气体的臭氧发生装置7A、具有与通过臭氧发生装置7A所供给的臭氧的作用进行液体净化的3个处理槽7B、7C、7D所构成。在臭氧发生装置7A上分别使用了例如在阴极上有白金触媒层的多孔质钛、在阳极上有二氧化铅触媒层等物质。
以下对上述构造的废水处理装置进行废水净化处理的流程进行说明。
在废水槽1中集中了来自各个医疗设施的治疗所使用过的废水。这时所谓的废水即例如齿科治疗时患者吐出的水或者从患者口中析出的唾液,就外科而言则是手术时从患者的体内吸出的血液或是体液,美容整形外科则为患者的皮下吸出的脂肪等。
在废水槽1中上述的废水渐渐积存,废水槽1内部的液面上升当这个液面达到高位的传感器的高度时,随着电动阀1C打开的同时,电动阀3C、4A被关闭。进而泵1A开始运行,将废水槽1中所积存的废水供给燃烧釜2。当废水供给燃烧釜2时废水槽1内部的液面降低达到低位的水位传感器的位置时,泵1A就停止运行。这里的高位和低位的传感器的高度要根据燃烧釜2的处理能力设置在适当的高度,期间提供给燃烧釜2的废水的量就是通过燃烧釜2处理的最适合的处理水量。
但是,在废水槽1所积存的废水中会含有不溶解于水的物质。如果这时就通过泵1A吸引废水,就会由于废水中所含的异物而堵塞泵1A而发生故障。这时就需要通过以下的方法来排除泵1A的堵塞。当泵被堵塞时,泵1A的负载就会变大。当泵的负载超过规定值时要将泵1A进行短时间逆转,将废水从燃烧釜2的燃烧室往废水槽输送,这样就能解除泵1A的堵塞。之后,使泵1A恢复正常运行,将废水从废水槽1向燃烧釜2输送。
向燃烧釜供给适量的废水之后,与电动阀1C关闭的同时电动阀4A被打开。进而本1A停止运行。之后供给燃烧釜2的燃烧室的废水通过加热器边进行加热,边通过搅拌机构2A得到搅拌。在这个过程中,废水被进行杀菌、脱臭的同时,也降低了废水中所含有的有机物质。随着废水被加热,在燃烧釜2的燃烧室中所发生的蒸汽由冷风装置4进行冷却,然后再供给气液分离装置5,进行液体与气体的分离。
供给燃烧釜2的燃烧室的废水被加热,水分被蒸发后,当燃烧室中只剩下粉尘时,在电动阀4A被关闭的同时,电动阀3C被打开。然后,由鼓风机3A将空气吹向燃烧室的同时,由真空装置3B吸引燃烧室内的空气。这样,燃烧室内残余的粉尘被回收到集尘装置中。粉尘被回收后,鼓风机3A与真空装置4B停止的同时电动阀3C被关闭。由于电动阀4A是在鼓风机3A动作期间关闭,因此,除了蒸汽以外的物质就不会被导入风冷***4中。通过集尘装置3回收的粉尘可在其他的工程中转换为例如二氧化硅等的再生材料。
通过气液分离装置5分离出来的气体供给二次燃烧装置6,通过燃烧釜的热量进行燃烧后可分解其臭的成分。被解除臭的成分的气体可以排放到大气中。另外,通过汽液分离装置分离的液体供给液体净化装置7,通过所使用的白金触媒而发生的臭氧气体进行净化。具体的则是将液体依照3个处理槽7B、7C、7D的次序通过臭氧的作用进行强力杀菌和脱臭,并降低其有机成分。净化后的液体可直接流入现有的下水道。
通过本实施形态的废水处理装置可净化来自医疗设施的各种废水,可排出不造成环境负荷并达标的清洁水。净化后的水可直接排放下水道装置中。
本实施形态中就来自医疗设施的废水进行处理的装置进行了说明,然而,本发明的废水处理装置除了医疗废水外还可以对工厂,一般家庭、店铺等的排放废水进行处理。
以下,就本发明的废水处理装置的第2实施形态参照图2进行详细说明。在上述的第1的实施形态中已经说明的构成要素的符号相同,在此对第2实施形态的符号说明不再重复。
本实施形态的废水处理装置是对建筑工地或公园、野营地等人数较多集中的场地上设置的临时沟槽的废水进行处理的装置。这个废水处理装置中除了在上述读第1的实施形态中已经说明的主要构成要素之外,还具有水洗式便器10与贮水槽11。
水洗式便器10是由将贮水槽11的清洗水暂时贮存的中继水箱10A与开闭水洗式便器的排出口进行开闭的开闭阀10B所构成。开闭阀10B是在操作中继水箱10A的操纵杆时,通过其联动动作打开水洗式便器的排出口。这时***物就会通过水洗式便器10的排出口随着清洗水一起流入废水箱1。在本实施形态下,所谓的需要处理的废水就是***物与用于将***物带出的清洗水混合的废水,废水箱1就是这种贮存废水的装置。
贮水槽11是将通过液体净化装置净化完成的水作为水洗式便器的清洗用水使用的贮水装置。在贮水槽的内部设置有检测贮水槽11满水时用的水位传感器。
下面,对上述构造的废水处理装置所进行的***物的处理及处理过的净水再利用的流程进行说明。
当用完水洗式便器10的利用者在进行冲掉***物而操作中继槽10A的操纵杆时,中继槽10A中的水就势向水洗式便器10的排出口冲去。同时,与清洗杆联动使得开闭阀10B动作,打开水洗式便器的排出口。临时保存在水洗式便器10中的***物被由贮水槽11所供给的水带着就势冲向废水槽1。
废水槽1内部的废水即随着***物和冲这个***物所用的清洗水一起慢慢蓄积,废水槽1内部的液面上升,当这个液面达到高位传感器的高度时,随着电动阀1C的打开,电动阀3C、4A被同时关闭。进而泵1A开始运行,将废水槽1中所积存的废水供给燃烧釜2。当废水供给燃烧釜2时废水槽1内部的液面降低达到低位的水位传感器的位置时,泵1A就停止运行。这里的高位和低位的传感器的高度要根据燃烧釜2的处理能力设置在适当的高度,期间提供给燃烧釜2的废水量,就是通过燃烧釜2处理的最适合的处理水量。
但是,废水槽1中所积存的废水中可能会混有内裤或生理用品等异物。如果用泵1A吸引这些含有异物的***物而堵塞泵1A发生故障。这时就需要通过进行上述的实施形态1的处理方法进行处理,这样就能解除泵1A的堵塞。
向燃烧釜供给适量的废水之后,与电动阀1C关闭的同时电动阀4A被打开。进而泵1A停止运行。之后供给燃烧釜2的燃烧室的废水通过加热器边进行加热,一边通过搅拌机构2A得到搅拌。在这个过程中,废水被杀菌、脱臭的同时,废水中所含有的有机物质也得到降低。随着废水被加热在燃烧釜2的燃烧室中所发生的蒸汽由冷风装置4进行冷却后再供给气液分离装置5,进行液体与气体的分离。
供给燃烧釜2的燃烧室的废水被加热,水分被蒸发后,在燃烧室中只剩下粉尘时,电动阀4A被关闭的同时,电动阀3C被打开。然后,由鼓风机3A将空气吹向燃烧室的同时,由真空装置3B吸引燃烧室内的空气。这样,燃烧室内残余的粉尘被回收到集尘装置中。粉尘被回收后,鼓风机3A与真空装置4B停止的同时电动阀3C被关闭。由于电动阀4A是在鼓风机3A动作期间关闭,因此,除了蒸汽以外的物质就不会被导入风冷***4中。通过集尘装置3回收的粉尘可在其他的工程中转换为例如二氧化硅等的再生材料。
通过气液分离装置5分离出来的气体供给二次燃烧装置6,通过燃烧釜的热量进行燃烧后可分解臭的成分。被解除臭的成分的气体可以排放到大气中。另外,通过汽液分离装置分离的液体供给液体净化装置7,通过所使用的白金触媒而发生的臭氧气体进行净化。具体的则是将液体依照3个处理槽7B、7C、7D的次序,通过臭氧的作用进行强力杀菌和脱臭,并降低有机成分。净化后的液体供给贮水槽11,可作为水洗式便器10的清洗水再次使用。
在本实施形态中下处理的是***物中所含的液体,并将这个液体作为水洗式便器10的清洗水进行利用,因此在设置这种临时厕所时,只需一次性向这个贮水槽11中加水即可。使用这个临时厕所之后,不会发生清洗水不足的问题。同时,也预想了发生贮水槽11发生溢水的情况。当贮水槽发生水过满的状况时,即贮水槽中的水面达到水位传感器的高度时,存在贮水槽11内的多余的水就会被供给二次燃烧装置6,将这个水通过加热然后气化,再排放到大气中,这样就不会发生从贮水槽中溢水的状况。
通过本实施形态的废水处理装置,可减低从临时厕所排出的***物的残渣的量,在解决了***物相关处理的问题的同时,还可防止臭气扩散到临时厕所内及其周边。由于将***物再生成为临时厕所的清洗用水,还可大幅度减少水的使用量。
在本实施形态中就设置在建筑工地现场或公园、野营地等较多人群集中的公共场所的临时厕所的废水处理装置进行了说明,但是本发明的废水处理装置除了可以在上述的临时厕所使用之外,还可以在户外或船舶、飞机、火车等上,用于对移动式或固定式的厕所排出的废水进行处理。
以上是参照图纸将本发明就本实施形态进行了说明,然而,具体的构造不限于这些实施形态,还包括可进行不脱离本发明的范围的设计变更。
本发明所述的废水处理装置具有积存需处理废水的废水积存槽,及加热前述的由前述的废水槽供给的前述的废水的燃烧釜,与收集前述的燃烧釜所发生的粉尘用的集尘装置和前述的冷却燃烧釜中产生的蒸汽所用的冷风装置,通过前述的冷风装置所冷却的蒸汽进行气体和液体分离的气液分离装置、将通过前述的气液分离装置分离出来的液体进行净化的液体净化装置等。前述的液体净化装置使用了白金触媒使之发生臭氧、就是通过这个臭氧将前述的液体进行净化。
通过本发明的废水处理装置,提供一种不仅是医疗设施就连一般的工厂、家庭、商店及多人聚集地公共场所等所排出的废水也能达到下水道排放标准的净化处理。
