项目摘要

The following results were obtained by this research.(1) The experimental system which recovers the ammonia and converts the ammonia into the nutrient with the soil and microorganism filter was manufactured experimentally in order to utilize the compost gas in the biological production. The system works well, however, the trace gas such as sulfur compound could not removed by the biofilter and was the barrier to growth. The carbon dioxide in the compost gas could be utilized for crop cultivation after the removing process of the trace gas through the honeycomb type catalytic filter.(2) The trace gas generated in the composting process of the garbage was examined comparing with the moist control material of the soil and the sawdust. The ability of soil to suppress the generation of methyl mercaptan was higher than the sawdust, but the methyl sulfide was controlled with the sawdust effectively.(3) A small-scale plant culture system using the compost gas which can be used in the home or s … More chool education was tested. The compost gas was trapped in the water and it was supplied to the soil of the plant growth media. The possibility in which gas supply is effective on the growth was shown by the experiment of komatsuna cultivation.(4) Shortening method of the soil respiration rate measurement using the gaschromatograph and the little soil sample was examined in order to distinguish the reaction of the biota in the soil deodorizer. Quantity reduction of soil sampling and shortening in culture time were also possible if the ratio between soil quantity and volume of the culture bottle was adjusted because the soil respiration rate measured with this experiment had high correlation with value of the NaOH method.(5) The change of nematode phase and microarthropod phase in the soil deodorizer was measured to examine the soil biomass variation in the deodorization process. Large arthropods such as ant and beetle were decreased, and Nematoda were increased with the progress of day. In the closed system of the soil deodorizer, species regarded as a top of trophic level seemed to be prickle acarine and trombiculid mite. Less

（1）通过土壤和微生物过滤器将氨转化为养分的实验系统，通过实验生产，以利用生物学生产中的堆肥气体，将氨转化为养分。但是，该系统运行良好，但是，生物滤器无法去除诸如硫化合物之类的痕量，并且是生长的障碍。堆肥气体中的二氧化碳通过蜂窝型催化过滤过滤器的痕量气体进行去除后，可以用于农作物培养。（2）与土壤和木屑的水分控制材料相比，检查了在垃圾的组成过程中产生的微量气体。土壤抑制甲基胃坦坦产生的能力高于木屑，但是用木屑甲基甲基硫化物有效地控制了甲基硫化物。（3）使用堆肥气体或可以在家庭或S中使用的小规模植物培养系统……更多的堆肥堆肥被困在水中，并将其供应到植物生长培养基的土壤中。通过Komatsuna培养的实验显示了气体供应有效的生长的可能性。（4）使用气体形式的缩短土壤呼吸速率测量方法和小土壤样品，以区分土壤除臭剂中生物群的反应。如果调整土壤数量和培养瓶的体积之间的比率，则可以减少土壤取样和培养时间缩短，因为通过该实验测量的土壤呼吸速率与NaOH方法的值相关。大型节肢动物（如蚂蚁和甲虫）减少了，随着一天的进展，nematoda增加了。在土壤除臭剂的封闭系统中，被认为是营养水平的顶部的物种似乎是刺杏仁酸和长脚肌。较少的
