Description

沼气型厌氧好氧一体生化反应器
技术领域
本发明涉及一种沼气型生化反应器,特别涉及一种对污水、污物进行处理的沼气型厌氧好氧一体生化反应器。
背景技术
目前,随着乡镇经济基础建设的快速发展,进一步完善乡镇分散型生活污水资源化利用的新型设施更显得尤为重要。现普遍应用的沼气型反应器结构设计虽然简单,但存在着不能同时处理固体、液体的不足;同时存在低温情况下污水处理能力较差、仅利用太阳能照射保温功能单一等问题。
因此,如何对生活污水、部分生活垃圾和农业废弃物进行无害化、资源化处理,形成循环利用的再生水资源,是该领域当前急待解决的难题之一。
发明内容
本发明的目的在于克服上述不足之处,提供一种对污水、污物进行处理效果显著的沼气型厌氧好氧一体生化反应器。
为实现上述目的本发明所采用的实施方式如下:
一种沼气型厌氧好氧一体生化反应器,其特征在于由沼气型厌氧池、自然接触式好氧池和贮水池连接所构成;厌氧池顶部前端开设进料进水口,垂直厌氧池底的前端设有曲流布料板,平行于厌氧池底间隔设有太阳能换热器,垂直厌氧池底的后端有折流板,在折流板两侧厌氧池壁上各开设1个出渣口,厌氧池顶部设有沼气导管,且厌氧池顶部后端开设检查口;所述厌氧池的末端与好氧池相连的池壁处设有好氧池进水口,所述好氧池的前端开设水压间,中间上下交替设置的隔板形成溢流槽;溢流槽逐级降低,形成水位落差的好氧池后端与贮水池相连;所述反应器整体外侧罩设保温棚。
所述反应器为地埋式,底层采用双层钢筋网,侧壁采用单层钢筋网。
所述厌氧池呈圆形,所述好氧池和贮水池分别呈矩形。
所述保温棚一侧开设门。
本发明的有益效果是:该反应器是适合乡镇分散型生活污水资源化利用的新型设备。该设备可对生活污水、部分生活垃圾和农业废弃物进行无害化、资源化处理,形成循环利用的再生水资源。本发明通过改变折流板的位置,来人为的设置了两个不同的处理空间,前端的厌氧池是固液混合段,固体从出渣口定期输出,后面的好氧池是污水的深度处理段;同时还充分利用太阳能换热,减少资源浪费,节能高效。本发明具有建设投资少,运行稳定,操作简便,吨水处理成本低廉等特点,且便于大范围推广应用。总之,本发明结构设计合理,使用方便,应用广泛,效果非常显著。

具体实施方式
以下结合附图和较佳实施例,对依据本发明提供的具体实施方式、结构、特征详述如下:
如图1-图4所示,一种沼气型厌氧好氧一体生化反应器,其特征在于由沼气型厌氧池1、自然接触式好氧池2和贮水池3连接所构成;厌氧池1顶部前端开设进料进水口4,垂直厌氧池1底的前端设有曲流布料板5,平行于厌氧池底间隔设有换热器7,与提供反应器热能的太阳能装置相连接;垂直厌氧池底的后端有折流板9,在折流板9两侧厌氧池1壁上各开设1个出渣口12,厌氧池1顶部设有沼气导管6,便于沼气的收集利用;且厌氧池1顶部后端开设检查口8。所述厌氧池1的末端与好氧池2相连的池壁处设有好氧池进水口13,所述好氧池2的前端开设水压间10,中间上下交替设置的隔板形成溢流槽11;溢流槽11逐级降低,形成水位落差的好氧池2后端与贮水池3相连;所述反应器整体外侧罩设保温棚15,所述保温棚15一侧开设门14。
沼气型厌氧池1呈圆形,圆形的厌氧池利于收集污物,不留死角;通过改进现有的沼气发酵池,将出水由上流式改为下流式,设计2处出渣口12,内设太阳能热交换式升温装置,即厌氧池底部铺设暖气片改装的换热器7,于地上的太阳能集热器进行热交换,冬季可提高水温2-3℃以上。自然接触式好氧池2呈矩形,采用升流式出水方式,池内设置生物载体规格3×1×0.5m(距水面0cm)。贮水池3呈矩形。
反应器规格:例如,厌氧池∮=5m,h=1.8m;好氧池26×3×1.7m;贮水池36×3×1.5m。整体采用钢筋混凝土结构,选用螺纹钢筋∮为12mm,12×12cm。混凝土C200。底层采用双层钢筋网,侧壁采用单层钢筋网,底厚30cm,侧壁20cm。反应器为地埋式,其主体材料为钢筋混凝土;反应器外部为保温棚15,整体采用全封闭,在冬季可提高水温5℃以上。
反应器上部安装保温棚15,长×宽×高为22×6×1.5m,上部为h=0.5的拱棚,材料为PPC双层。在保温棚15的侧面空地上安装太阳能集热器,共30m2
反应器工作原理:排放的污水、污物先由经过厌氧池的进料进水口进入,经过曲流布料板、折流板后进入水压间,经过水压间后污水进入好氧池,经过溢流槽,清水进入贮水池,完成水处理工作。同时,厌氧池的物料经过曲流布料板,均匀分布在厌氧池底,再经过设有的两处出渣口顺利完成出渣工作,且有利于沼渣的收集、利用。本发明利用厌氧、好氧(自然接触式)相结合的工艺、结构,采用自然水位落差方式,污水处理过程中不需曝气等动力消耗,只需进水时提升污水的动力。大大的降低了污水处理过程中的能耗。反应器通过厌氧发酵降解水中难降解大分子有机物,杀灭水中病源微生物;再通过自然接触式好氧过程进一步降解水中有机物,达到处理生活污水的目的。
上述参照实施例对沼气型厌氧好氧一体生化反应器进行的详细描述,是说明性的而不是限定性的,因此在不脱离本发明总体构思下的变化和修改,应属本发明的保护范围之内。
