背景技术
随着我国改革开放和经济发展，我国畜牧业得到迅猛发展，大大改善了市民的“菜篮子”，提高了人民群众的生活水平。我国畜牧业为农业和国民经济贡献卓著：2010年肉类产量7925万吨，连续21年居世界第一；禽蛋产量2765万吨，连续26年居世界第一；奶类产量3780万吨，居世界第三。伴随畜牧业的快速发展，城市区域环境和农村生态环境成了巨大的压力，畜禽养殖业产生污染日趋严重。因此，加强畜禽养殖业的污染防治与环境管理已成为农村环境保护工作重大而紧迫的任务。
以浙江嘉兴市为例，嘉兴市地处长三角中心位置，北有苏州，南邻杭州，东依上海。从上世纪90年代初发展起生猪养殖业，主要供应周边市场。作为传统的生猪养殖密集区，目前嘉兴全市的养猪户已经超过了10万户，每年生猪出栏量450万头。大规模密集饲养的条件下，猪的死亡高在所难免，通常情况下，成年母猪死亡率每年达到2％～3％，中龄猪死亡率达到7％～8％，而乳猪死亡率更高，据中央台在当地专题报道，从小猪生下来到最后出栏平均总死亡率10％。按上述数据计算，嘉兴地区每年各种原因死亡的猪将达到几十万头。每年都有大量的病死家畜得不到无害化处理，有的甚至被丢进河里，不仅严重污染环境，而且传播口蹄疫、高致病性禽流感、高致病性猪蓝耳病、猪瘟等重大动物疫病。
城市生活垃圾是人们生活中产生的固体废弃物。在收集、运输和处理处置过程中，垃圾中所含有的和产生的有害成份，会对大气、土壤、水体造成污染，不仅严重影响城市环境质量，而且威胁人民身体健康，成为社会公害之一。中国城市垃圾人均年产量达到440公斤，1996年，中国城市生活垃圾清运量就已达到了1亿吨，而且每年以8％至10％的速度增长。垃圾的历年堆存量达到60多亿吨，全国有200多座城市陷入垃圾的包围之中。垃圾堆存侵占的土地面积多达5亿多平方米。如何解决城市垃圾问题，还城市乡居民一个健康洁净的生存环境，已引起全社会的高度重视。
目前，很多地方将病死家畜和城市垃圾等有机垃圾采用焚烧的办法进行处理。焚烧处理过程中不仅产生硫化氢(臭味)污染空气，而且排放很多如二恶英、氮氧化物、二氧化硫等有毒有害的物质，影响周围居民的身体健康。上述病死家畜和城市垃圾等有机垃圾之所以在焚烧过程中产生硫化氢(臭味)、二恶英、氮氧化物、二氧化硫等有毒有害的物质，主要的原因是在有氧状态下进行热解(燃烧)处理。病死家畜和城市垃圾中的氨氮在有氧的状态下热解(燃烧)产生氮氧化物；硫在有氧的状态下热解(燃烧)产生二氧化硫；氯离子在有氧的状态下热解(燃烧)产生二恶英；炭在有氧热解(燃烧)的状态下产生二氧化碳等。
是否可以采用一种无氧热解的方法和设备，将病死家畜和城市垃圾等有机垃圾在无氧状态下进行热解，解决病死家畜和城市垃圾等人类生产、生活过程中产生的有机垃圾的资源化、无害化处理难题，避免产生硫化氢(臭味)、二恶英、氮氧化物、二氧化硫等有毒有害的物质，至今尚未见报导。
