This study exam ined the regulation status on w astew ater treatm ent in agro-food processing and a case study on effluent treatm ent m ethods w as carried out to evaluate any change after the m itigation of regulation. First, in order to clarify the area of investigation, the definition of sm all-scale agro-processing facilities w as review ed through literature survey and local governm ent ordinance. The current law w ere separately analyzed into four areas; effluent treatm ent facilities, developm ent of agro-processing industries, land use and food processes equipm ent. The exclusion clauses on w astew ater discharging facility in the enforcem ent regulation w ere defined in detail, w hich can be served in practice. Site survey, after the questionnaire survey of the person in charge of the local unit, w as carried out. As the result, this survey confirm ed the positive effects of the deregulation on prom oting sew er system service in rural areas, introducing the new processing construction and so on. In addition, it w as found that som e m atters to be considered to determ ine w hether to introduce w astew ater treatm ent plan for public food processing facilities.

This study was carried out to provide a valuable reference which could reduce heating loss of air-inflated double PO film. Therefore, this study was aimed to choose the best air space thickness and injected air temperature. The characteristics of heat transmission variation at experimental materials were measured and analysed in the laboratory. The experiment was conducted of two layers of PO film, each 0.15 mm tick, sandwiching 110, 175, 225 mm of inflated air with 1 m sides. Environmental control lab was constantly controlled with -10 ℃ and experiment chamber was constantly changed with 0, 5, 10, 15 ℃. The analysis of heat transfer showed that heat transmission does not have a direct correlation with Air Space thickness and injected air temperature. But when inside and outside temperature difference of chamber was great, supply of outside air to Air Space had an advantage at reduction of heating load. It was required to examine accurate analysis at a real greenhouse.
