Industrial Cluster Upgradation of Regenerated Resources in Miluo City

With China's rapid economic growth, ecological construction and environmental protection become increasingly important. The regenerated resources industry is an effective way to solve problems, such as resources depletion, energy shortage, and pollution, and it also has strategic importance for the construction of a resource-conserving and environment-friendly society. The regenerated resources industry has been established in Miluo for long time, which includes a recycling system, a processing and utilization system, and a refuse decontamination system. An industrial cluster is in its early stage of development. In order to solve current problems, such as short industrial chain, low processing rate, and low added value, the industrial cluster should be dynamically upgraded by means of technology innovation, chain nucleus creation, and chain extension. We think the industrial cluster of regenerated resources will become a local brand for Miluo, from which other regions or cities will gain valuable experiences and inspirations.

蚯蚓对城镇污泥堆肥过程中微型动物群落演替的影响

采用实验对比和除趋势对应分析（DCA）等方法,以城镇污泥中的微型动物为对象,研究蚯蚓对堆肥过程微型动物群落演替的影响.结果表明,蚯蚓仅影响微型动物群落数量,对演替进程无明显影响.堆肥过程微型动物群落演替可分为3个阶段：第1阶段（0~10 d）,固着类纤毛虫为优势类群阶段,该阶段微型动物变化多受限于环境的改变,蚯蚓影响较小;第2阶段（10~30 d）,固着类纤毛虫和轮虫向肉足虫和线虫为优势类群的过渡阶段,该阶段蚯蚓对线虫数量有一定的限制;第3阶段（30 d后）,肉足虫和线虫为优势类群阶段,该阶段蚯蚓对有壳肉足虫的增长产生了明显的抑制作用.群落多样性指数结果显示,蚯蚓在第1和第2阶段作用不明显,在第3阶段增加了微型动物的多样性和均匀度,减小了优势物种的优势程度.对固着类纤毛虫的同化作用是蚯蚓稳定堆肥环境、促进有机质降解的重要因素.
