1、問:有的A/O工藝中,A段為厭氧段,為什么還要空氣管曝氣呢?

2、問:我做的100噸中試項目,近期氨氮去除效果不好,目前觀察的情況看:供氧應該還可以、堿度充足、生物活性尚可且無明顯毒性、污水悶曝還是不行,是否可以認為負荷不成問題?有機氮的氨化和硝化,是不是同時進行,其中氨化要稍微領先于硝化?有沒有其它影響硝化的因素?

3、問:我現調試一個屠宰廢水,工藝為:化糞池(HRT>2d)-調節池-水解池(HRT=5)-接觸氧化池(HRT=6)-二沉池,由于前化糞池出水COD在700,而且接觸氧化時間比較短,故將水觸池改為曝氣池,但所加的一臺潛水曝氣機效果有限DO一般在0.5以下,原曝氣池DO正常.兩池的SV都可達到20-30,現在進水量為設計水量的70%,出水水質仍然很差,SS較多,原曝氣池有一定的泡沫,且比較稠,是否是因為污泥老化的原因造成的?

6、問:近段時間本單位的污泥脫水機(帶式壓濾)濾布常會跑偏,是什么原因?

7、問:我們的好氧池為生物接觸氧化池,目的是將氨氮從30降至10以下,實際現在加顯色劑后和空白差不多。加碳酸鈉調節堿度,從后面沉淀池回流污泥,由于回流不好控制,所以有時是泥有時是水。以前發現沒污泥回流時整個好氧池的pH值就隨水流方向急劇下降,但有污泥回流時就不會了,能保證出水pH值在6.5-7之間。但近幾天發現整個好氧池pH值偏低,前端僅6.9,出水5.8左右(進水所有指標和碳酸鈉量均未改變,氨氮濃度依然測不出),即使相對以前改善污泥回流狀態也是這樣請問這是什么原因造成的?另外我們好氧池后面的沉淀池是豎流沉淀池(148m3,水量30m3/h),下面有四個小泥斗,在現有狀況下應采取什么措施改善好氧池回流污泥狀態?
