首先,我來提第一個問題,大家可以根據問題討論,也可以提出問題。
屠宰廢水難點在預處理,那么預處理的工藝選擇上應該怎么考慮?
格柵、絲網能否解決問題?

支持管管!但我不太懂這方面的問題。
請問:屠宰廢水是有機污染源,有很大危害性,那么我們國家有沒有出臺針對屠宰廢水處理的相關規范或標準?再者環保部門建議運用怎樣的工藝開展屠宰廢水預處理呢?

MBR本身對氨氮應該沒多大影響吧。不過MBR可以截流污泥,增加硝化菌的數量,從而強化氨氮的去除效果

沒接觸過屠宰廢水。。。但,聽師父說過屠宰廢水的案例。。。難點在預處理。。。

能不能上傳一些現場照片呢?不同的水,生化池內泥的顏色和狀態應該都有所不同。。。求圖。。。

工藝是格柵+初沉池+調節池+厭氧池+SBR+消毒。白天氣溫5度左右,晚上基本在0度以下。由于溫度原因,厭氧基本上沒培養起來,請教下各位,A.這個條件下厭氧部分該怎樣培養?  B.SBR池進水后產生大量泡沫,這個問題如何解決??分段進水,消泡劑,噴淋???請問正常運轉的屠宰廠污水處理系統有這個問題嗎??各項參數維持多少??

DO在2mg/L。污泥沉降比在40%左右。其他數據,現場估計不一定有化驗室。</div></div>

謝謝寂寞版主。
厭氧池沒有投加污泥,現在是回流好氧污泥。SBR池SV30現在維持在40%,多余污泥就往厭氧池回流。

看你這個流程,厭氧池其實應該是水解酸化池,這種水解酸化池+SBR工藝,水解都是帶填料的,不是AO ,污泥不需要回流。<div><br></div><div>填料的水解酸化池,嚴格來說還是厭氧反應,這種污泥用好氧池的接種,效果不會好。還是找厭氧污泥,或者厭氧堆積過的污泥來投加,本身水解酸化池的菌種培養就很慢,好氧污泥進入,會更慢。</div><div><br></div><div>將來厭氧池調試好了,千萬要記住,正常運行的時候,SBR的污泥,不要進入厭氧池。</div>

之所以色度這么深,是因為活性污泥不成熟,有機物高,處理完成后,裝到瓶子里面,和礦泉水差不多,稍微帶色。<div><br></div><div><br></div><div>沉住氣吧,需要時間,不需要考慮脫色。</div>
