- 摘要:
- 杭州市萧山区某餐厨垃圾厌氧消化处理项目设计处理能力为餐厨垃圾200 t/d、地沟油20 t/d。采用预处理+厌氧消化+沼气利用的主流工艺路线。根据功能定位，系统分为预处理系统、地沟油提纯系统、厌氧消化及脱水系统、污水处理系统、沼气净化及利用系统以及辅助生产系统等6大系统。餐厨垃圾通过预处理后形成油脂、有机浆液、固渣三股物料，油脂与地沟油提纯后的油脂作为毛油对外销售；有机浆液与固渣一并进行厌氧消化；厌氧消化产生的沼气在厂内净化后部分用作锅炉燃料，部分发电上网。项目工程总投资15 386.43万元，约合69.8万元/t。项目达产后，运行效果良好，CSTR湿式厌氧消化运行稳定，全量厌氧时产气率高、出水水质好。
- Abstract:
- A food waste anaerobic digestion treatment project in Xiaoshan District, Hangzhou City was designed to dispose the municipal waste of 200 t/d food waste and 20 t/d gutter oil. The mainstream process route of pre-treatment+anaerobic digestion+biogas utilization was adopted in the project. According to the functional requirement, the project was divided into six major systems: pre-treatment system, gutter oil purification system, anaerobic digestion and dewatering system, sewage treatment system, biogas purification and utilization system, and auxiliary production system. After pre-treatment, food waste was divided into three streams of materials: oil, organic slurry and solid slag. Oil extracted from food waste and gutter oil was sold as crude oil. The organic slurry and solid slag was treated by anaerobic digestion. Biogas produced from anaerobic digestion was partially used as boiler fuel after purification in the plant，and the rest part was used for the generation of electricity power. The total investment of the project was 153.864 3 million yuan, and the investment per ton was approximately 698 000 yuan. The operation exhibited good performance and was well controlled. CSTR anaerobic digestion process showed stable operation performance with high production rate of biogas and high quality of effluent.
