出水色度这么深?色度怎么去除最好呢?H2O2、次氯酸钠行吗?

支持管管!但我不太懂这方面的问题。
请问:屠宰废水是有机污染源,有很大危害性,那么我们国家有没有出台针对屠宰废水处理的相关规范或标准?再者环保部门建议运用怎样的工艺开展屠宰废水预处理呢?

看你们格栅都是转鼓式的,没人用耙齿式的?我们用的都是耙齿式的,效果很好啊!
还有请问有没用过污泥烘干设备的?效果怎么样

其实生活污水,养殖废水,发酵废水,垃圾渗滤液都是一样的,不过是浓度不同而已,而且这些污水是完全可以用微生物变成饮用淡水,但是投加化工药剂之后,就无法治理了!

首先,我来提第一个问题,大家可以根据问题讨论,也可以提出问题。
屠宰废水难点在预处理,那么预处理的工艺选择上应该怎么考虑?
格栅、丝网能否解决问题?

MBR本身对氨氮应该没多大影响吧。不过MBR可以截流污泥,增加硝化菌的数量,从而强化氨氮的去除效果

没接触过屠宰废水。。。但,听师父说过屠宰废水的案例。。。难点在预处理。。。

能不能上传一些现场照片呢?不同的水,生化池内泥的颜色和状态应该都有所不同。。。求图。。。

工艺是格栅+初沉池+调节池+厌氧池+SBR+消毒。白天气温5度左右,晚上基本在0度以下。由于温度原因,厌氧基本上没培养起来,请教下各位,A.这个条件下厌氧部分该怎样培养?  B.SBR池进水后产生大量泡沫,这个问题如何解决??分段进水,消泡剂,喷淋???请问正常运转的屠宰厂污水处理系统有这个问题吗??各项参数维持多少??

DO在2mg/L。污泥沉降比在40%左右。其他数据,现场估计不一定有化验室。</div></div>

谢谢寂寞版主。
厌氧池没有投加污泥,现在是回流好氧污泥。SBR池SV30现在维持在40%,多余污泥就往厌氧池回流。

看你这个流程,厌氧池其实应该是水解酸化池,这种水解酸化池+SBR工艺,水解都是带填料的,不是AO ,污泥不需要回流。<div><br></div><div>填料的水解酸化池,严格来说还是厌氧反应,这种污泥用好氧池的接种,效果不会好。还是找厌氧污泥,或者厌氧堆积过的污泥来投加,本身水解酸化池的菌种培养就很慢,好氧污泥进入,会更慢。</div><div><br></div><div>将来厌氧池调试好了,千万要记住,正常运行的时候,SBR的污泥,不要进入厌氧池。</div>

之所以色度这么深,是因为活性污泥不成熟,有机物高,处理完成后,装到瓶子里面,和矿泉水差不多,稍微带色。<div><br></div><div><br></div><div>沉住气吧,需要时间,不需要考虑脱色。</div>
