概要

The purpose of this study is to recreate the circulation system of resources in the rice crop agicultural field. The graywater purification has been experimented using carbonized chaff on the life sewage. The 2 experiments were implemented : Middle period (2 times at 8 : 00 and l 6 : 00 per day and continuously for 1O days), and Short period (every 2 hours ranging from 6 : 00 to 22 : CO per day). Conductivity, pH, turbidity, DO, water temperature, depth and water speed were measured in respect of treated water and untreated water. As a result, the following effects can be obtained : (1) DO rise to the level of rice plants can grow up to, pH rise to the level of fishes can breed. (2) Aquatic lives were identified that were inexistent before the experiment in the area. We can look upon the graywater to be treated by the index biology.
