Description

一种快速匹配废水和填料挂膜的装置及方法 技术领域
本发明属于生物膜法污水处理技术领域,更具体地说,涉及一种快速匹配废水和填料挂膜的装置及方法。
背景技术
在污水处理的二级生化处理系统中,活性污泥法和生物膜法占主导地位,生物膜法由于具有水量水质适应性强、对有机物的去除、脱氮除磷及去除重金属效果良好、动力费用省等优点,得到了广泛的关注和应用。生物膜主要由微生物细胞和它们所产物膜进行生长、成熟和老化的循环。生物膜的载体一般有软性填料、组合填料以及悬浮填料等。软性填料和组合填料由于其具有重量轻、比表面积大、空隙可变、不易堵塞、耐冲击负荷等效果稳定,且造价低、运输方便和组装简易等特点,被率先广泛应用于处理纺织、印染、酿酒、石油化工等工业和生活污水的处理中。但是在实际的废水挂膜过程中,由于水体复杂,污泥菌群组成差异大,导致同一性质的填料在不同的水体中挂膜性能差异明显。因此,对用于实际工程的填料长时间的小试挂膜试验或者直接投加填料进行挂膜不仅耗时耗力,而且很有可能会挂膜失败。因此,亟待开发有效快速的方法进行对挂膜水体匹配最优的挂膜填料,达到填料高速挂膜的目的。
中国专利申请号为CN101913710A,授权日期为2011年10月5日公开了一种悬浮填料微生物快速挂膜的方法,该方法其特征是首先将污泥取回后曝气48h,用曝气后的污泥做接种菌,接种于装有悬浮填料的序批式SBR反应器中,曝气6h,静置沉淀6h;然后投加营养基质,曝气l0h,静置沉淀2h作为一个运行周期,每天运行2个周期,期间进行排泥保持污泥悬浮固体浓度保持在2-20g/L范围内的某一浓度值不变;运行7-25d挂膜即完成。但此方法运行时间长,且损耗资源多。
中国专利申请号为CN105461083A,公开日期为2016年5月4日,该方法公开一种用于微生物快速挂膜的悬浮填料,所述悬浮填料由以下重量份的组分组成:高密度聚乙烯65~75份、熟石灰5~15份、陶氏粉末活性炭5~20份、轻质碳酸钙6~10份、马来酸酐3~5份、过氧化二异丙苯0.2~0.6份、明胶1.5~3份、甲壳素1~2份、四氧化三铁磁粉0.8~2份和锰锌铁氧体0.1~0.3份;所述用于微生物快速挂膜的悬浮填料的密度为0.96~0.98g/cm3。此填料使用窄,适用性不广泛。
目前针对快速挂膜的策略主要有两种,第一种即通过高污泥浓度情况下挂膜,且通过投 加外源物质进行强化挂膜;而第二种主要是通过对填料本身进行改性,让其更加适合于特定水体挂膜。然而,针对未知水体及大量各种不同性质的填料,这两种方式均属于耗时耗力且没有对现有资源合理化应用的方法。

实施例1
某工业废水存在出水水质不能满足一级(A)的要求,拟采用生物膜法对原有的好氧池进行升级改造。
本实例的具体实施过程为:
1)对目标挂膜泥水混合物进行采样,采用匀浆器进行匀浆;匀浆次数为15次。
2)将充分匀浆的泥水混合物用10微米滤膜进行过滤,取滤液;
3)将滤液分为两份,一份滤液标记为滤液A;另一份滤液经过再一层0.22微米滤膜过滤后取滤液,标记为滤液B,其为滤液A的参照溶液;
4)将1号膜片3固定于成膜监测舱室4内;
5)将快速匹配废水和填料挂膜装置组合完成;
6)将滤液A从进水口5通过蠕动泵打入;滤液A进入流速为1mL/min;
7)待滤液A上升直到从出水口6流出时,开启超声发生器9,开启超声反射模式,调整超声发生器9参数到设定值,开启示波器10,通过控制系统11在线实时显示;超声发射器8的参数选择范围为重复频率20Hz,脉冲电阻30Ω,脉冲电压400V,增益60dB,高通滤波0.03MHz,低通滤波1MHz;
