基于蝇蛆养殖技术的畜禽粪便处理模式

现阶段我国的畜禽养殖固体废弃物利用程度仍不高，堆肥是畜禽粪便无害化资源化的重要技术手段之一。但主要以低效益的常规单一有机肥生产为主，大量的畜禽养殖固体废弃物资源得不到有效利用，造成环境污染。蝇蛆是畜禽养殖固体废弃物的高效生物转化器，畜禽废弃物可经蝇蛆生物转化后生产蝇蛆蛋白和优质有机肥。该文针对传统堆肥经济效益低、辅料依赖性强、处理周期长和成本高等特点，结合主要畜禽粪的组分特征及理化特性，在现有的蝇蛆生物转化畜禽粪工艺基础上，通过对蝇蛆生物转化畜禽养殖固体废弃物的产业化共性关键技术和设备进行研究，实现畜禽养殖固体废弃物的生态治理和高值化利用。 

Manure Treatment Mode of Livestock and Poultry Based on Fly Maggot Culture Technology

At present，the utilization degree of solid waste from livestock and poultry breeding is still not high，composting is one of the important technical means of harmless resources utilization of livestock and poultry manure.However，the production of conventional single organic fertilizer is mainly based on low efficiency，and a large number of livestock and poultry breeding solid waste resources could not be effectively utilized，resulting in environmental pollution.Fly maggot is an efficient biological converter of solid wastes from livestock and poultry breeding.The animal waste could be transformed into fly maggot protein and high quality organic fertilizer.According to characteristics of traditional compost such as low economic benefit，high dependency of auxiliary materials，long treatment cycle and high cost，combined with characteristics of main components and physicochemical properties of animal manure，based on existing bio-conversion process of fly maggot animal manure，through the study of key technology and equipment of industrialization of bio-conversion of solid waste from livestock and poultry breeding，the ecological management and high value utilization of solid waste from livestock and poultry breeding could be realized.
