城鎮(zhèn)水務發(fā)展與技術論壇圓滿結束！我們水資源可持續(xù)專場再見

　　【農機網 會展快訊】5月已經過半，但2022青島國際水大會專家大講堂的“接龍”之旅才正式開始！整個5月接6月，海水淡化與濃鹽水綜合利用專場、工業(yè)節(jié)水與污水資源化專場、城鎮(zhèn)水務發(fā)展與技術專場、水資源可持續(xù)發(fā)展專場等8個專場陸續(xù)與您相約。
 
　　可以看到，8場連播踩準了當前水務市場備受關注的話題，如污水資源化和海水淡化兩種“開源”渠道，再如水環(huán)境綜合治理和水生態(tài)修復，以及與民生息息相關的凈水問題，和“雙碳”戰(zhàn)略目標下必須作答的綠色、低碳、可持續(xù)“論述題”，看了才知道，是“真的香”。
 
　　同理，5月17日的這場城鎮(zhèn)水務發(fā)展與技術論壇，蹲點的小伙伴有沒有覺得“不虛此行”呢？
 
　　沒有來得及看直播，雖然錯過了在線互動，但是回顧也可以安排起來呀↓

 

　　演講主題：中國合流制問題與改造
 
　　唐建國 上海市城市建設設計研究總院(集團)有限公司 總工程師
 
　　合流制、分流制是城市排水體制兩種并存的形式，各有優(yōu)缺，其中合流制造價低、占用道路資源和維護管理工作量相對較少，因此也是世界上較早采用的排水系統(tǒng)形式，并沿用至今。其缺點跟當前熱點話題——雨污分流密切相關，即雨季時超過管道排水能力的會出現溢流現象。唐建國總工程師針對合流制，介紹了日本大阪、東京，德國，美國在合流制改善方面的措施和做法，包括著名的費城“綠色英畝計劃”，并表示，中國“海綿城市”建設不妨吸取費城的成功經驗。
 
　　同時，唐建國總工程師還指出，到底適不適合采用合流制，一看雨水標準夠不夠，二看截流倍數夠不夠，三看溢流污染大不大，我國顯然這三個關鍵點均不能滿足。“我們很多城市就埋了‘一根管’”，“一根管”可不是合流制，因此在爭論合流制和分流制之前，要正確認識合流制這個概念。
 
　　那么，我國合流制到底應該怎么改呢？盲目改造不可取，快去在線論壇里找答案。

 

　　演講主題：城鎮(zhèn)污水處理廠深度脫氮除磷技術研究與應用
 
　　萬年紅 中國市政工程中南設計研究總院有限公司，副總工兼研究院院長
 
　　“我國城鎮(zhèn)污水處理廠水污染物排放標準日益趨嚴，甚至趨于地表Ⅳ類標準”，在這樣的背景下，北京、天津、浙江、湖南，太湖、巢湖、岷沱江等地方和流域陸續(xù)對總氮、總磷提出了高去除要求。萬年紅院長表示，這也對污水處理廠的深度脫氮除磷提出了比較大的需求，并就著這個問題介紹了從ENR(強化脫氮除磷)到LOT(極限脫氮除磷)的相關情況。
 
　　LOT工藝，通過強化二級處理+深度處理+超深度處理(氣浮、DBAF、膜)，TN、TP可以達到準地表Ⅲ、Ⅳ類標準：TN 3-1mg/L；TP 0.1-0.05mg/L。據萬年紅院長介紹，目前中國市政工程中南設計研究院污水處理試驗基地涵蓋了從CSO-預處理、一級強化處理、二級處理、深度處理到生態(tài)處理的全過程工藝優(yōu)化探索，開展的中試研究在二級生化處理、深度脫氮、高級氧化去除新污染物等方面與中國污水處理概念廠(宜興)主流工藝路線不謀而合。
 
　　是不是越聽越感興趣了呢？再刷一遍，走起~
 


 

　　演講主題：紫外線水處理技術研究進展與應用
 
　　賈瑞寶 山東省城市供排水水質監(jiān)測中心 主任
 
　　從非強制到強制，從側重技術要求，到增加法律效力，我國《生活飲用水衛(wèi)生標準》(GB5749-2022)即將于明年4月1日正式實施。面對消毒處理要求的個中變化，紫外線消毒具有高效、廣譜的特點，并且常規(guī)劑量不產生消毒副產物，對抗氯菌也有較好的滅活效果，當然對腺病毒滅活能力有限，且沒有持續(xù)性消毒效果。
 
　　賈瑞寶主任分析，總的來看，我國紫外線水處理技術生產企業(yè)實力較弱，用戶運維質量較差，標準體系不完善，設備整體技術水平較低。“紫外線發(fā)生器產品檢測能力需要第三方認可的CMA 資質認證，促進行業(yè)技術進步和可持續(xù)健康發(fā)展”，對于行業(yè)的未來展望，賈瑞寶主任認為，國產紫外線裝備+高級氧化工藝帶來了可行方案。
 
　　想了解更多紫外高級氧化技術的技術和應用，當然不能錯過這么精彩的分享啦~

　　演講主題：低噪音、低振動泵技術在水務行業(yè)中的應用
 
　　吳宏飛  南方泵業(yè)股份有限公司  副總工程師
 
　　泵閥設備一直是各行各業(yè)的高能輔助，而隨著近年我國對生態(tài)環(huán)境保護的重視，包括環(huán)保標準的趨嚴，輔助“換裝”節(jié)奏也不得不跟上。南方泵業(yè)作為國內較早開始規(guī)模化生產不銹鋼沖壓焊接離心泵，致力于成為“綠色水動力專家”的技術型企業(yè)，早早就開始布局泵系統(tǒng)的節(jié)能、降碳、減排、低噪升級，為各大合作商實現自身的減污降碳目標作出了不小的貢獻。
 
　　本次吳宏飛副總工程師帶來的二供用泵市場背景、實現的技術以及應用案例解讀，就能看出不少“含金量”。針對二供行業(yè)面臨的泵類產品振動和噪音大、節(jié)能效率低、產品故障率高、老舊小區(qū)改造空間有限等等問題，南方泵業(yè)運用了什么樣的低振動低噪音方案？所謂的CFD仿真分析有哪些優(yōu)點？SS高效靜音水務專用泵好在哪？不要猶豫，來線上論壇找答案吧。

　　喜歡本次特別策劃的2022青島國際水大會專家大講堂的小伙伴，別忘了點贊、分享、遞名片哦，繼3大專場圓滿落下帷幕，下次見面就是在水資源可持續(xù)發(fā)展論壇啦。
 
　　2022年5月24日，2022青島國際水大會專家大講堂專場四：水資源可持續(xù)發(fā)展，歡迎參與在線互動！我們，下次見！
