style="font-size:16px;">有言在先，答應寫個調試分享，現在有點后悔，來不及了，不想寫也得寫。沒多想，那就只能從最大眾的氨氮硝化問題來著手了。自己也是一直在從事這個高氨氮廢水，做過的廢水氨氮基本都在600以上，絕大部分都是走生化路線，不是不想用其它的好法子，實在是沒錢玩不動。</span></span></p> <p style="margin: 0px; padding:

style="font-size:16px;">既然要寫高氨氮廢水硝化的調試經歷，那就高一點，沒上千氨氮的項目都拿不出手了，反正這里吹牛也不扣工資。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">一個近期驗收成功的養殖廢水項目的調試過程寫給大家。項目本來不急的，準備慢慢來，忽然環保給壓力，催促著給辦了，剛好趕上。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;"><strong style="margin: 0px; padding: 0px; border: 0px;">2、出發前干點啥</strong></span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">去之前呢，按照一直的習慣，主要做了兩件事：（1）是先去問設計把資料要過來，意料之中，除了方案、圖紙之外，也是個沒有計算書的項目，一如既往的風格沒有進步嘛；（2）是找現場同事解了一下實際情況，跨專業的小白，已經調試了3個多月了，難為人家講了一大堆，反正知道池子里有泥，這樣也行吧，調試期間的水質數據發了過來，然后安排再做一次各位置的水質檢測。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">工程設計處理的厭氧沼氣池的出水，主體工藝“AOAO-MBR-混凝沉淀”。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">根據了解的設計資料和現場實際反饋情況分析對比，發現一個大的問題就是來水的氨氮濃度超設計，目前出水氨氮濃度也比較高。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">看到這個實際進水的氨氮濃度，嚇得我趕緊找圖紙核算一下池容。他娘的設計真是個天才，池子好大，進水氨氮濃度翻了倍，池容也綽綽有余，后面還有MBR。不愧是業主做土建的項目，真的是穩。順便看一下風機參數，兩用一備，氣水比可達250，變頻控制。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">這樣的情況，心里就踏實了，養殖廢水普遍是沒有其它有毒有害物質抑制硝化的，在池容、風量設計夠的前提下，通過工藝參數的調整，氨氮基本都能給你整達標。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino

text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">磕磕碰碰總算到了地方，場子比較偏僻，很安靜適合養老。不墨跡，直接開始干活了。熟悉一下現場構筑物、管道和近期的運行狀況。經同事介紹，基本都是滿水量負荷進的，由于水質超標，當前出水到氧化塘儲存，主要用與澆灌，這么高的氨氮，也不知道果樹們過得如何。接著拿上儀器，到池子上排查工藝控制參數。差不多是心中預期的樣子：</span></span></p> <p

style="font-family:宋體;"><span style="font-size:16px;">（1）水質：來水氨氮濃度已經知道，目前出水氨氮也有200多ppm；</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（2）DO：還不錯，一級好氧在1-2，二級好氧4-6了；</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（3）MLSS：測不了，做SV30%，兩級AO基本都在40%～50%之間，雖然狀態不健康，量還是可以的；</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（4）堿度/pH：看pH，進水7-7.5，MBR出水6.5的死樣子，這個pH，硝化需要的堿度肯定是不夠了；</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（5）回流：一級好氧回流到一級缺氧是4倍回流量，二級好氧回流到二級缺氧是4倍回流量；這個回流比對設計進水600mg/L的氨氮濃度是正確的，只是目前進水氨氮濃度遠超設計，需要更大的回流量來稀釋，控制進入好氧池的氨氮濃度在抑制濃度以內。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">問題找到，就要著手開始解決了，直接列個表方便：</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">這個項目條件比價好，“step1”保持了連續5天沒有進水，在連續補堿保持池內pH的基礎上，MBR出水COD下降至270mg/L，NH4+-N降至30mg/L后，才開始恢復逐步進水，提負荷。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">后期調試一直到滿水量負荷，DO、堿度一直保持關注，氨氮一直處于較低值的穩定狀態，COD有所波動，這是養殖廢水在高氨氮時常出現的亞硝酸鹽積累，需要注意回流和保證反硝化效果。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family:

style="margin: 0px; padding: 0px; border: 0px;">4、完結</strong></span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">好了，今天寫不動要賴皮了，算我可恥一回。最后搞點建議給被硝化問題困擾的小伙伴，聊表心意。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（1）多了解處理廢水來源，找出水質中可能對硝化或生物處理造成影響的抑制、有毒有害物質，經常關注。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（2）拿到設計資料，了解設計的思路和意圖，并與現場實際情況比對。這實際包含了對負荷、污泥濃度和系統處理潛力的確認，做到心中有數。比如此次設計的600氨氮，實際到了1300～1500咱也敢去調，原因就是先知道了這個系統它有這個處理能力，否則大神也白瞎。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（3）關于硝化的主要工藝控制參數是：MLSS、DO、堿度、回流比。小伙伴們很大部分硝化不好的情況，原因都是出在這4個工藝參數上。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（4）心理預期，如果沒有肯定的經驗或者數據依據，不要吹牛逼說一定能在短期內解決硝化問題，容易打臉。出現了硝化問題，應該盡量多爭取時間，特別是在中毒抑制、硝化菌死亡或者隨污泥流失的情況下，恢復過程是相當的漫長。</span></span></p> <p style="margin: 0px; padding: 7px 20px; border: 0px; font-family: 微軟雅黑, "Hiragino Sans GB", 宋體, sans-serif; line-height: 26px; text-indent: 2em; color: rgb(51, 51, 51); font-size: 16px;"> <span style="font-family:宋體;"><span style="font-size:16px;">（6）最后希望小伙伴們建立自信，沒有別人可以解決而你解決不了的硝化問題。前輩們經驗多、思路清晰，能夠系統的分析問題，找出原因，并提出系統的解決方案。我們通過學習和總結，可以建立自己的一套分析和解決硝化問題的方法，這個能力是可以在短期內快速提高的。</span></span></p> <br /> <hr /> <p> 上一篇：<a
