| 摘 要： | 利用蚯蚓对吉林市某污水厂剩余活性污泥进行了处理,主要研究蚯蚓在此过程中的生长与繁殖状况,通过比较蚯蚓在久置污泥与未完全发酵牛粪配比中和新鲜污泥与腐熟牛粪配比中的生长繁殖状况,找出最适合蚯蚓生长繁殖的污泥与牛粪的配比.为蚯蚓在污泥处理中的应用提供科学依据,为利用蚯蚓处理城市污水厂污泥过程中蚯蚓生长繁殖方面的研究奠定基础,因此具有较重要的理论意义和实践意义.

| Abstract: | This paper introduces a method of the surplus activated sludge treatment by earthworms. In a Wastewater Treatment Plant in Jilin City,the condition and state of earthworms'growth and reproduction during the treatment are researched. The optimum ratio of sewage sludge and cow dung suitable for earthworms'growth and reproduction is worked out. So the scientific basis of the earthworms'application in sludge treatment is provided,and the foundation for the research of earthworms' growth and reproduction in the ... |
