项目摘要

The main purpose of this study is to produce a sustainable circulation sewage purification system by plants, and biomass in closed environment, from an ecological point of view. Different analyses and evolution of water quality on a circulation system to produce biomass by aquaponics of a Living Machine in CNES of Nihon Univ. were carried out. The results in 2002, the sewage purification system had worked to purify the sewage of animal on T-N and T-P. On the other hands, the study in case of the system to produce biomass, the minitomato that absorbed fish excrements was 25% heavier than the one that absorbed animal excrements. Second study in 2003 is the purpose about grasping of the mineral nutrient balance of payments in a fundamental circulation system that research towards development of Aquaponics that performs Aquaculture and Hydroponics products sustainable and simultaneously within a closing circulation system. Agricultural products absorbed much DIN in the Aquaculture drainage … More of carps, but DIP precipitated and decreased, so its processing and reuse is a subject. When the comparison of the mineral nutrient in each agricultural products, The tomatoes and herbs absorbed many DIN and DIP, and The amounts of edible biomass harvest were tomatoes(849g/m^2),water convolvulus(2,677g/m^2),and herbs(964g/m^2)for four months. It was considered that Aquaculture of carps could be performed, DIN they are 18 and DIP 75 carps from the excretion speed measurement experiment of carps.In the complex development experiment of natural water quality purification materials, the rate of NO3-N removal improved in the combination of the solution of straw and the reed with charcoal, and zeolite. The possibility of preventing the water quality aggravation by NO3-N by the compound system of this purification material was shown. When combined with the solution of straw, there is especially no fall of the removal capability of NO3-N, and Org-N also suited its tendency of control. The combination with charcoal of Binchotan was shown that COD concentration is low stopped rather than the case of othersBy testing the moisture controls of straw and straw bale, we showed the benefit of the straw bale wall for ecological houses in Japan.

本研究的主要目的是从生态学的角度出发，在封闭环境中，利用植物和生物质，建立一个可持续的循环污水净化系统。对日本国立空间研究中心的一个利用水生植物共生技术生产生物质的循环系统进行了不同的分析和水质演变。2002年的研究结果表明，该污水净化系统对畜禽养殖污水的T-N和T-P有一定的净化作用。另一方面，在生产生物量的情况下，吸附鱼粪的微生物量比吸附畜禽粪的微生物量重25%。2003年的第二项研究旨在掌握基本循环系统中的矿物质营养收支平衡，该研究旨在开发在封闭循环系统中同时可持续地执行水培和水培产品的鱼菜共生技术。农作物对水体中DIN的吸收量较大 ...更多信息但由于DIP沉淀减少，其加工和再利用是一个课题。在比较各种农产品中的矿质营养时，番茄和草本植物吸收了大量的DIN和DIP，四个月的可食用生物量收获量为番茄（849 g/m^2）、空心菜（2, 677 g/m^2）和草本植物（964 g/m^2）。从鲤鱼排泄速度测定实验来看，认为可以进行鲤鱼养殖，DIN为18条，DIP为75条。在天然水质净化材料的复合开发实验中，稻草、芦苇溶液与木炭、沸石组合使用，NO3-N去除率提高。表明了该净化材料复合体系防止NO_3-N对水质恶化的可能性。尤其是与秸秆溶液组合时，对NO3--N的去除能力没有下降，有机氮也符合其控制趋势。通过对秸秆和草捆的水分控制试验，说明了日本生态住宅用草捆墙的效益。少
