摘要:
《上海市生活垃圾管理条例》实施后，湿垃圾终端处理面临巨大挑战。上海市某湿垃圾资源化处理工程项目湿垃圾处理量为500 t/d（其中餐饮垃圾150 t/d、厨余垃圾350 t/d）、废弃食用油脂为30 t/d，总体工艺路线采用垃圾协同预处理+联合湿式厌氧消化+沼气综合利用+污水协同处理组合工艺。餐饮、厨余垃圾预处理后的物料协同水解酸化形成中低温液相，厨余垃圾沥水、餐饮垃圾废水和废弃油脂协同提油后形成高温液相，两股浆液协同进行厌氧产沼发电，油脂外售。污水处理系统处理规模为1 200 m3/d，采用两级AO+外置式超滤+NF+RO组合工艺，通过餐饮垃圾废水、湿垃圾离心沼液、焚烧厂渗滤液和渗滤液厌氧沼液的合理调配，系统进水碳氮比不低于9.9∶1，无需外加碳源。项目总投资约8.73 亿元，约合164.7 万元/t。湿垃圾预处理和污水处理均高效协同，运行稳定，出水达标排放。
Abstract:
The terminal treatment of wet waste is facing great challenges after the implementation of Shanghai Municipal Solid Waste Management Regulations. The wet waste recycling project in Shanghai has a treatment capacity of 500 t/d for wet waste (including 150 t/d food waste and 350 t/d kitchen waste) and 30 t/d for waste edible oil. The combined process consists of collaborative pretreatment, combined wet anaerobic digestion, comprehensive utilization of biogas and collaborative sewage treatment. The products generate from the pretreated food waste and kitchen waste are hydrolyzed and acidified synergistically to form a medium-low temperature liquid, and the kitchen waste leachate, food waste sewage and waste oil are extracted synergistically to form a high temperature liquid. The two kinds of liquids are digested synergistically to produce biogas and generate electricity, and the extracted oil is sold. The treatment capacity of the sewage treatment system is 1 200 m3/d, using a two-stage AO, external ultrafiltration, nanofiltration and reverse osmosis combined process. Through the reasonable allocation of food waste sewage, wet waste centrifugal biogas slurry, incineration plant leachate and leachate anaerobic biogas slurry, the influent C/N ratio is no less than 9.9 ∶1, and there is no need to supplement additional carbon source. The total investment of the project is about 873 million yuan, and the unit investment is approximately 1.647 million yuan/t. The wet waste pretreatment and wastewater treatment are highly cooperative, and the effluent quality stably meets the limit specified in the discharge standard.
