導讀:視環(huán)會第三日,市政污泥處理處置研討會與協同減污降碳·危廢環(huán)境污染治理與資源化利用論壇雙雙登場,你探到了什么?

  【農機網 會展快訊】4月14日,市政污泥處理處置研討會與協同減污降碳·危廢環(huán)境污染治理與資源化利用論壇雙雙登場。上午看市政污泥處理處置研討會,共研“雙碳”與污泥處理處置的深度融合方案,下午置身協同減污降碳·危廢環(huán)境污染治理與資源化利用論壇,探道危廢資源化回收及循環(huán)利用。
 
  市政污泥處理處置研討會特邀嘉賓:


 

  上午9點30分,市政污泥處理處置研討會在期盼聲中正式啟程。
 

 這邊回顧↑
 
  中國市政工程西南設計研究總院有限公司副總工程師劉波 就“碳中和背景下的污泥處理處置技術”進行專題分享。據其介紹,我國的污泥處理處置量在2020年就已超過6000萬噸,污泥處理處置技術的進步是推進我國污泥行業(yè)發(fā)展的重要一環(huán)。碳中和背景下,污泥處理處置技術發(fā)展更需做好“加減法”。一手減少溫室氣體排放,一手增加碳匯、發(fā)展碳捕集和封存技術等。
 
  目前,污泥干化焚燒技術具有多方面優(yōu)勢,污泥處理處置相對徹底、自身熱值利用率高、產物可再利用、占地小、工藝成熟、應用案例多……上海市政工程設計研究總院(集團)有限公司第三設計院總工程師助理/高級工程師盧駿營緊接著就切入到污泥干化焚燒技術并展開詳細分析。
 
  污泥干化焚燒技術如何在運行中踐行雙碳目標?
 
  盧駿營表示,有先進的焚燒技術、高效穩(wěn)定的干化技術及有效的余熱回收技術的三面共推,節(jié)能減排效益可以實現大幅度提升。此外,其認為焚燒系統(tǒng)的節(jié)能重點在自持焚燒,自持焚燒對節(jié)能減排具有著重大意義。最后,盧駿營給出節(jié)能減排技術的發(fā)展方向:提高污泥熱值、降低進污泥干化焚燒系統(tǒng)含水率、污泥干化后載氣冷凝余熱的回收。
 
  其后,威立雅水務工程(北京)有限公司 污泥市場經理王維燕“碳進”污泥資源化、無害化處理技術。
 
  王維燕認為,雙碳背景下的污泥處理需要將污水與污泥處理同時考慮,污泥資源屬性與污染屬性、污泥資源化利用與污水廠能量相平衡。污泥處理需要穩(wěn)定化、無害化,也需要減少碳排放。污泥消化技術、生物脫硫技術、厭氧氨氧化技術、污泥濕式氧化技術、污泥焚燒技術……這場技術大放送,王維燕在總結時進一步表示消納、協同消納是“雙碳”背景下市政污泥及生物質資源化利用的有效途徑;厭氧氨氧化工藝可減少消化回流液對污水處理線的影響;濕式氧化工藝是一種環(huán)境友好的污泥減量化和無害化處理工藝。
 

  沒聽夠?那就再重溫一遍!
 
  康碧環(huán)境技術(北京)有限公司中國區(qū)業(yè)務拓展經理鄧締圍繞高級厭氧消化介紹與北京排水集團的污泥處理案例,帶來了一份可研性較高的污泥處理方案。
 
  熱水解技術作為一種污泥高效厭氧消化技術,鄧締介紹到該技術可提高厭氧消化進料負荷、改善脫水性能、改善污泥產品質量、增加沼氣產量20%-50%及降低整體工藝碳排放。可以看到,該技術正在強化污泥處理處置中的碳減排效益。鄧締也從北排集團自有項目中工藝流程的規(guī)劃與選擇、項目建設與試運行等多方面進行案例論證。其認為,熱水解技術在污泥消化提升中的作用將逐漸凸顯,污泥厭氧消化也將成為未來行業(yè)發(fā)展的重要趨勢。
 
  上午市政污泥處理處置研討會中的技術賦能不斷,下午14點,協同減污降碳·危廢環(huán)境污染治理與資源化利用論壇也要接續(xù)“技術熱”!

  點擊回顧↑
 
  知名環(huán)保人士黃小山為本次論壇主持開場后,屬于環(huán)保人的危廢治理主題交流活動正式拉開帷幕。
 
  山東省工業(yè)固廢資源循環(huán)利用創(chuàng)新中心的劉科副主任圍繞水泥窯協同處置危廢技術的發(fā)展路徑進行具體論述。
 
  水泥窯協同處置危廢技術在行業(yè)、處置需要增長的多方驅動下,近年來呈現爆發(fā)式增長趨勢。劉科副主任表示,近兩年建成、在建和規(guī)劃建設的水泥窯協同處置危險物項目超過百余項,項目主要以4000噸以上窯型為主,單體規(guī)模10萬噸/年。遠觀未來,劉科副主任認為代替原料與代替燃料將是該項技術未來很長一段時間內的重要發(fā)展方向。
 
  合能環(huán)境上海公司徐知遙總經理就工業(yè)廢棄物資源回收技術及無害化處理技術展開細致分享。
 
  資源回收技術——VacuDry®真空熱脫附技術,一款能夠實現將污染物、廢棄物轉化為可再生能源的低溫真空熱脫附工藝技術;無害化處理技術——Pyreg®碳化技術,碳化處理混合物料并輸出生物炭和再生能源。徐知遙總經理對它們的技術優(yōu)勢、適用領域、工作原理等多方面進行的分析,你“愛”了嗎?
 
  北京中科國潤環(huán)保科技有限公司的李忠鋒董事長以飛灰資源化處置技術為主題帶來講解。
 
  李忠峰先生著重介紹的這款飛灰水洗脫鹽(FWD)技術主要利用三級或多級逆流漂洗方式對飛灰、窯灰等物料進行水洗,完成二次利用或脫毒目的。據分析,該技術分離效果好、水消耗少、不具二次污染,還能保證副產鹽資源化。

 

  環(huán)保,不退讓!
 
  明天的固危廢檢測鑒別技術網絡研討會繼續(xù)接上今天這波熱度!
