摘要
随着中国养殖业的迅速发展,禽畜粪便的排放数量逐年增加。据统计,禽畜粪尿排放量每头牛为55kg/d^65 kg/d,每头猪为3.5 kg/d^11.0 kg/d,每只鸡为0.10 kg/d^0.15 kg/d,每只羊为2.66 kg/d。大量的禽畜粪便不经处理而排入环境,将会对地表水、地下水、土壤和空气造成严重的污染,并危及禽畜本身及人体健康。因此,实现禽畜粪便的减量化、无害化及资源化,防止和消除养殖场粪便的污染及其利用问题的研究,对于生态环境的保护、实施可持续发展战略都具有十分重要的意义。本试验利用日本JST赠送的生态厕所反应装置为试验设备,分别以木屑和木屑与秸秆混合物为微生物载体,对牛粪便进行减量化处理技术研究。旨在为研究中国农业的玉米作物秸秆是否可以替代木屑作为反应过程中的调理剂,达到对禽畜养殖业粪便良好的减量化处理效果,减轻对环境的污染,同时也为中国大量的农作物秸秆寻找另一条资源化利用途径。
With the rapid development of aquaculture, The number of livestock manure emissions has increased year by year. According to statistics, livestock waste emissions per head of cattle for the 55 - 65 kg/d, pigs for every 3.5 - 11.0 kg/d, chicken for 0. 10 -0. 15 kg/d, each sheep to 2.66 kg/d. A large number of livestock manure is not treated and discharged into the environment, it will cause serious water soil and air pollution and endanger their livestock and human health. As a result, study on the technology of reduction livestock manure, elimination of hazards and resources to prevent and eliminate pollution of farm manure and use of research for the protection of the ecological environment, the implementation of the strategy of sustainable development are very important significance. This paper researched on the treatment of cattle manure with the bio - toilet presented by JST in Japan. Respectively sawdust and the mixture of straw and sawdust for the carrier, for reduction of cattle manure treatment technology research. In order to study on whether using the cornstalk replaces with the sawdust as bulking agent.
