Description
技术领域
本发明涉及污水处理技术领域，具体涉及一种污水臭氧氧化处理工艺。
背景技术
城市污水包括城市地区范围内的生活污水、工业废水和径流污水。生活污水主要是人类生活中使用的各种厨房用水、洗涤用水和卫生间用水所产生的排放水，多为无毒的无机盐类。生活污水中还含有大量有机物，如纤维素、淀粉、糖类和脂肪蛋白质等；也常含有病原菌、病毒和寄生虫卵；无机盐类的氯化物、硫酸盐、磷酸盐、碳酸氢盐和钠、钾、钙、镁等。总的特点是含氮和含磷高，在厌氧细菌作用下，易生恶臭物质。目前大部分城市都设有污水处理点对这些生活污水进行处理后再排放至外界，以保护生态环境。城市居民的生活污水通过管道进入生活污水处理厂，经过充氧、搅拌、发酵、沉淀等过程，将污水变成干净、无污染的水，保护了河道和城市水源，保护了环境。然而，处理生活污水的过程中由于沉淀以及化学反应等原因，会产生大量的固体杂质，这些固体杂质会沉淀下来，进而产生了大量的污泥。污泥中含有大量的有机质和氮磷钾元素，COD值偏高，远远无法达到国家排放标准。
发明内容
(一)要解决的技术问题
为了克服现有技术不足，现提出一种污水臭氧氧化处理工艺。
(二)技术方案
本发明通过如下技术方案实现：本发明提出了一种污水臭氧氧化处理工艺，包括如下步骤：S1、先把生活污水经过格栅过滤杂质后流入初沉池沉淀后把上清液分别通入两组反应池；S2、两组反应池内反应后的污水分别通入不同的混凝池加入絮凝剂搅拌絮凝，且两组混凝池内的污水在通入不同的二沉池沉淀； S3、在把初沉池、反应池及其二沉池内的污泥通入泥浆混合罐内压缩泥浆后进行泥浆脱水处理；S4、脱水后的污泥去除金属后干燥粉碎，再把污泥外排用于农业或者沤肥，而污泥排出的污水通过水泵回流到初沉池内；S5、两组二沉池内的上清液分别进行紫外线杀菌消毒操作后一组二沉池内的处理水直接排出，且另一组二沉池内的处理水再分别通入两组消毒池；S6、两组消毒池分别对处理水进行加臭氧脱色和反渗透净水，然后再分别加氯消毒排出；S7、脱色后的处理水通入自来水厂用于人们使用，而反渗透的处理水可以当做纯净水直接使用。
(三)有益效果
本发明相对于现有技术，具有以下有益效果：
本发明提到的一种污水臭氧氧化处理工艺，与传统的产品相比，本发明利用不同的反应池和后续处理可以在对污水处理的时候起到不同的作用，从而在提高污水处理质量的同时降低了后续处理步骤，分阶梯处理污水用于不同的作用，而且对于污泥也可以萃取池脱去污泥中的重金属，对产生的底泥农业化利用，减少了二次环境污染，提高了资源利用率，该发明工艺路线短，成本较低，便于操作，功能多样，适用范围广，安全稳定，有利于推广和普及。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
一种污水臭氧氧化处理工艺，包括如下步骤：S1、先把生活污水经过格栅过滤杂质后流入初沉池沉淀后把上清液分别通入两组反应池；S2、两组反应池内反应后的污水分别通入不同的混凝池加入絮凝剂搅拌絮凝，且两组混凝池内的污水在通入不同的二沉池沉淀；S3、在把初沉池、反应池及其二沉池内的污泥通入泥浆混合罐内压缩泥浆后进行泥浆脱水处理；S4、脱水后的污泥去除金属后干燥粉碎，再把污泥外排用于农业或者沤肥，而污泥排出的污水通过水泵回流到初沉池内；S5、两组二沉池内的上清液分别进行紫外线杀菌消毒操作后一组二沉池内的处理水直接排出，且另一组二沉池内的处理水再分别通入两组消毒池；S6、两组消毒池分别对处理水进行加臭氧脱色和反渗透净水，然后再分别加氯消毒排出；S7、脱色后的处理水通入自来水厂用于人们使用，而反渗透的处理水可以当做纯净水直接使用。
本发明提到的一种污水臭氧氧化处理工艺，与传统的产品相比，本发明先利用两组孔径不同的格栅对污水进行过滤，然后在进行沉淀和厌氧反应释放磷氨化，从而便于反应池对污水的去氮除磷，卡鲁塞尔氧化沟反应池对污水去氮除磷后经过紫外线灯杀菌消毒和调节PH值后可以达到国家排放标准，卡鲁塞尔氧化沟反应池产生的废气经过空气净化处理可以减少空气污染，而MBR膜生物反应池在对污水去氮除磷后经过两组不同的方式对处理水进行杀菌消毒后可以用作自来水和直接使用，提高对污水处理的效果和质量，同时对污水处理产生的污泥经过萃取金属和污泥脱水后用作农业，可以减少资源浪费，防止二次污染，节能环保，本发明利用不同的反应池和后续处理可以在对污水处理的时候起到不同的作用，从而在提高污水处理质量的同时降低了后续处理步骤，分阶梯处理污水用于不同的作用，而且对于污泥也可以萃取池脱去污泥中的重金属，对产生的底泥农业化利用，减少了二次环境污染，提高了资源利用率，该发明工艺路线短，成本较低，便于操作，功能多样，适用范围广，安全稳定，有利于推广和普及。
上面所述的实施例仅仅是对本发明的优选实施方式进行描述，并非对本发明的构思和范围进行限定。在不脱离本发明设计构思的前提下，本领域普通人员对本发明的技术方案做出的各种变型和改进，均应落入到本发明的保护范围，本发明请求保护的技术内容，已经全部记载在权利要求书中。
