昆明市污水处理厂污泥处理工艺的研究与探讨
- Title:
- Research and Discussion on the Sludge Disposal Technology of Kunming WWTPs
- 摘要:
- 昆明市主城区及环湖区域共22座水质净化厂，当前污泥产量为1 061.54 t/d（污泥含水率为80%），现状污泥处理能力仅为529 t/d，污泥的处理处置已成为亟待解决的问题。对昆明市现状污泥进行了泥质分析，结果显示污水处理厂污泥混合后可以满足土地利用、卫生填埋、建材利用（水泥熟料生产）及焚烧等处置方式。系统分析昆明当前各种污泥处置途径的可行性，推荐的污泥处置途径为水泥窑协同焚烧处置（资源化利用），卫生填埋作为有效补充。对厌氧消化、好氧发酵、干化焚烧等3种污泥处理方式进行技术比较，结合本工程的污泥处置途径，确定采用热干化的污泥处理方式。对圆盘热干化等5种干化设备进行比选，推荐采用圆盘干化。该工程技术路线为圆盘热干化+水泥窑协同焚烧，工程投资2.49亿元，单位处理成本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.
