摘要
根据武汉市东西湖区养殖场实际情况,规划设计了一整套以沼气生产为纽带的循环经济工程技术模式,分析评估了养殖业固废处理循环经济实施的经济效益和环境社会效益。该模式以"暗河式大型联合沼气生产技术"为基础,将畜禽废弃物经过一系列的生物厌氧发酵产生沼气;沼渣、沼液结合好氧堆肥保温设施生产优质有机肥料;以现代化污水处理系统和人工湿地生态化处理沼液和养殖场废水,达到中水回用的标准;湿地种植饲料植物。在彻底消除畜禽养殖废弃物产生的环境污染的同时,实现养殖场循环经济生产模式的正常运作与发展。研究设计结果对其它地区实施养殖业固废处理循环经济模式具有一定借鉴意义。
With the plants in east and west lake regions of Wuhan as examples, a whole set of planning and design was proposed for the recycling economy engineering mode with the marsh gas as link, and our group have explained the meaning of recycling economy for dealing with solid waste of feeding, and have objectively analyzed economic benefits, environmental and social benefit after recycling economy of feeding is implemented. The result shows ：That Implementing of recycling economy mode for dealing with solid waste of feeding will get the objective economic benefits, good environmental and social benefit.
