昆明市污水處理廠污泥處理工藝的研究與探討
- Title:
- Research and Discussion on the Sludge Disposal Technology of Kunming WWTPs
- 關(guān)鍵詞:
- 市政污泥; 污泥處理; 熱干化; 水泥窯協(xié)同焚燒
- 摘要:
- 昆明市主城區(qū)及環(huán)湖區(qū)域共22座水質(zhì)凈化廠，當(dāng)前污泥產(chǎn)量為1 061.54 t/d（污泥含水率為80%），現(xiàn)狀污泥處理能力僅為529 t/d，污泥的處理處置已成為亟待解決的問題。對(duì)昆明市現(xiàn)狀污泥進(jìn)行了泥質(zhì)分析，結(jié)果顯示污水處理廠污泥混合后可以滿足土地利用、衛(wèi)生填埋、建材利用（水泥熟料生產(chǎn)）及焚燒等處置方式。系統(tǒng)分析昆明當(dāng)前各種污泥處置途徑的可行性，推薦的污泥處置途徑為水泥窯協(xié)同焚燒處置（資源化利用），衛(wèi)生填埋作為有效補(bǔ)充。對(duì)厭氧消化、好氧發(fā)酵、干化焚燒等3種污泥處理方式進(jìn)行技術(shù)比較，結(jié)合本工程的污泥處置途徑，確定采用熱干化的污泥處理方式。對(duì)圓盤熱干化等5種干化設(shè)備進(jìn)行比選，推薦采用圓盤干化。該工程技術(shù)路線為圓盤熱干化+水泥窯協(xié)同焚燒，工程投資2.49億元，單位處理成本361.8元/t。
- Abstract:
- There are 22 wastewater treatment plants (WWTPs)in main districts and lake surrounding area of Kunming, which produce 1 061.64 t/d of sludge with water content of 80%. The present sludge treatment capacity is only 529 t/d, so sludge disposal has become an urgent problem to be solved in Kunming. The analysis results of local sludge characteristic show that the mixed sludge can meet the requirements of land use, sanitary landfill, building materials utilization as cement clinker production and incineration. Through systematically analyzing the feasibility of sludge disposal ways in Kunming, cement kiln incineration for resource reclamation is recommended as sludge disposal method, and sanitary landfill is taken as supplementary disposal. After comparing with three sludge disposal methods including anaerobic digestion, aerobic fermentation and dry incineration, and combining with the sludge disposal methods of this project, thermal drying was determined as sludge treatment methods. Five drying equipment such as disc drying are compared and disc drying is recommended. Thus disc thermal drying and cement kiln incineration are selected as the technical route of the project. The investment is 249 million yuan, and the unit processing cost is 361.8 yuan/t.
