Description
一种畜禽养殖废水的处理系统
技术领域
[0001] 本实用新型属于废水处理领域，更具体地说，涉及一种畜禽养殖废水的处理系统。背景技术
[0002] 畜禽养殖废水是含高浓度有机物、营养物的废水，它的直接排放造成了严重水环境污染。但畜禽养殖业污染治理水平普遍较低，据统计，全国90%的规模化畜禽养殖场污染物处理达不到环保要求，这不仅导致了水体的富营养化，同时也制约了畜禽养殖业的发展。
[0003] 随着近年来我国污水厌氧技术的迅速发展，各种新工艺、新方法不断出现并被应用到畜禽养殖废水的处理过程中来，比如厌氧挡板反应器、厌氧复合反应器、厌氧滤池等。如中国专利公开号CN101955299A，公开日2011年I月26日，公开了一种高效养殖场废水处理系统，该系统包括沉淀池、调节池、厌氧反应器、出水收集池、砂式出水处理池和后续处理池。该发明具有处理效率高、占地面积小、造价低、维护实用方便等特点；又如中国专利公开号CN202766382U，授权公告日2013年3月6号，公开了一种畜禽养殖废水处理装置，该装置包括调节池、厌氧EGSB反应器、中间沉淀池和多级生物滤池，该装置处理效果好、能耗低，并做到资源回收利用的同时创造效益。中国专利号CN103274571A，公布日2013年9月4号，公开了一种畜禽养殖废水的资源利用和处理方法，该发明基于厌氧消化产沼气技术、BAF技术和消毒技术相结合，处理效果好、能耗低、综合利用资源的同时产生经济效益。
[0004] 但上述所涉及的厌氧反应器在处理畜禽废水的过程中均存在一定的问题:首先，为保证处理效果或者处理要求较高时，厌氧池的深度较大，增加了建造费用；其次，厌氧处理过程中会产生一定量的沼气，而气体产生量又不足以为此设置专门收集设施，为节约成本，这些温室气体基本都直排大气，增加了温室效应。与此同时，为提高氮的去除率，畜禽养殖废水处理过程中往往会设置反硝化单元，但常会出现填料的堵塞，影响反硝化的效率以及系统的稳定运行，造成处理后的水不能达标排放。
发明内容
[0005] 1.要解决的问题
[0006] 针对现有技术中存在的畜禽废水处理系统建筑成本高、产生的温室气体直排大气以及反硝化单元易堵塞的问题，本实用新型提供了一种畜禽养殖废水的处理系统，该系统提高了脱氮率，体现了 “以废治废”的理念，节约成本，易于操作。
[0007] 2.技术方案
[0008] 本实用新型的目的是通过如下技术方案实现的:
[0009] 一种畜禽养殖废水的处理系统，它包括ABR池和好氧生物滤池，它还包括反硝化池，所述的ABR池与好氧生物滤池之间通过污水管道连接，所述的污水管道伸入好氧生物滤池的一端设置有雾化喷头，所述的污水管道上设置有提升泵；
[0010] 所述的好氧生物滤池通过管道将出水送入反硝化池，所述的反硝化池内设置有滤料，滤料下方设置有曝气装置，该反硝化池的底部设置有出水口。[0011] 优选地，所述的ABR池顶部覆盖有沼气膜，用于收集和储存产生的沼气，反硝化池的曝气装置的进气口通过气体管道与ABR池连接，ABR池的侧壁上设置有进水口。
[0012] 优选地，所述的好氧生物滤池中的生物滤料为微孔生物滤料，其粒径为10〜15mm。当废水流经生物滤料时，与生物滤料发生反应，微孔生物滤料的粒径控制在10〜15mm,保证了废水与生物滤料发生充分的接触。
[0013] 优选地，所述反硝化池内的滤料为轻质滤料，其粒径为4〜6mm。
[0014] 优选地，所述ABR池、好氧生物滤池以及反硝化池采用砖砌或混凝土结构。
[0015] 3.有益效果
[0016] 相比于现有技术，本实用新型具有以下有益效果:
[0017] (I)本实用新型的技术方案中，在ABR池顶部覆盖有沼气膜，用于收集和储存产生的沼气，增加了厌氧环境，使得ABR池的建造深度降低，节约成本；
[0018] (2)本实用新型的系统结构中包括除了 ABR池和好氧生物滤池之外，还包括反硝化池，在反硝化池内的滤料下方设置有曝气装置，通过曝气作用有效地避免了滤料堵塞的发生；此外，ABR池产生的甲烷通入反硝化池，减少了温室气体甲烷的排放；
[0019] (3)由于甲烷具有增温作用，将甲烷通入反硝化池，可以增加反硝化池的处理效率，提高了脱氮率，体现了 “以废治废”的理念，易于操作。

具体实施方式
[0022] 下面结合附图和具体的实施例对本实用新型的技术方案做进一步的详细描述。
[0023] 实施例1
[0024] 结合图1，本实施例的畜禽养殖废水的处理系统包括依次连接的ABR池1、好氧生物滤池2和反硝化池3，ABR池1、好氧生物滤池2以及反硝化池3采用砖砌结构。ABR池I与好氧生物滤池2之间通过污水管道5连接，污水管道5伸入好氧生物滤池2的一端设置有雾化喷头9，该雾化喷头9上设置有多级雾化喷嘴。污水管道5上设置有提升泵4。
[0025] 好氧生物滤池2通过管道将出水送入反硝化池3，好氧生物滤池2内设置有半软性的生物滤料10，该生物滤料10为微孔生物滤料，其粒径为10mm。
[0026] 反硝化池3内设置有滤料，反硝化池3内的滤料为轻质滤料11，其粒径为4mm。滤料下方设置有曝气装置12，该反硝化池3的底部设置有出水口 13。
[0027] ABR池I由3〜4个隔室组成，每个隔室内均加有厌氧污泥。ABR池I顶部覆盖有沼气膜8，用于收集和储存产生的沼气，反硝化池3的曝气装置12的进气口通过气体管道6与ABR池I连接，接入收集的沼气。在ABR池I的侧壁上5/6高度处，设置有进水口 7。
[0028] 实际工作时，将畜禽养殖废水从进水口 7引入ABR池1，在厌氧菌作用下分解和去除水中有机物，停留24小时后，通过提升泵4，污水进入好氧生物滤池2进一步去除有机物和氮磷，滤后水进入反硝化池3，在曝气甲烷的环境中继续脱氮，污水最终由反硝化池3尾端的出水口 13排出。处理水量为7m3/h，进水水质为=CODcr浓度为4500mg/L，悬浮物浓度为660 mg/L，NH3-N浓度为330mg/L，pH为7.4。出水水质的检测指标为CODcr浓度为98mg/L，悬浮物浓度为22 mg/L, NH3-N浓度为20mg/L，其有机物浓度指标、悬浮物浓度指标以及氨氮指标完全满足《畜禽养殖污染物排放标准》GB18596-2001的排放标准。
[0029] 实施例2
[0030] 本实施例的技术方案基本与实施例1相同，其不足之处在于，该好氧生物滤池2内的微孔生物滤料粒径为15_。反硝化池3内的轻质滤料11粒径为6_。
[0031 ] ABR池1、好氧生物滤池2以及反硝化池3采用混凝土结构。
[0032] 实施例3
[0033] 本实施例的技术方案基本与实施例1相同，其不足之处在于，该好氧生物滤池2内的微孔生物滤料粒径为12_。反硝化池3内的轻质滤料11粒径为5_。
[0034] ABR池1、好氧生物滤池2以及反硝化池3采用混凝土结构。
