Evaluation and Estimation of Environmental Pollutant Load and Environmental Resources Related to Citizens' Lifestyle in Complex of Urban and Rural Area toward Future Recycle-Oriented Society

对城乡水、物、能平衡进行了评价。本研究主要针对天然水和人工水的复合体，其中污染物和能量通量随水循环而流动。首先，在考虑水质的情况下，对每种用水的详细需水量进行了评估。对建筑物内部或每个城市街区内部雨水和废水回用的有效性进行了评估。在建议的评估方案中，对雨水和废水的质量进行了评估，以供每种用水(如冲水马桶、洗车和泉水花园)的再利用。将这些估算方案应用于大阪和鸟取市地区，并对肉类用水量的减少率进行了评估。其次，调查了城市和农村自然水循环和人工水循环的污染物负荷。特别对中水回用水质评价的重要指标--颗粒污染物负荷进行了详细的分析。PO-…的粒度分布在一些降雨过程中，观测到较多的暴雨径流。相对较大的颗粒物负荷集中在降雨持续时间的早期。由于雨水的粒径分布决定了雨水对污染物的去除能力，因此可以评估雨水再利用的适宜储存时间。调查了大气污染和汽车对城市地面沉积污染物在道路和屋顶表面的分布情况。由于大量受污染的雨水在不到10分钟的时间内被浓缩，因此可以估计合适的时间。最后，以生态效率为指标对固体废物处理系统进行评价。计算了城市生活垃圾处理过程中的发电量和排热量，作为有效利用和服务。计算的环境污染物负荷为污泥和无用热量。生态效率测算方案是建立未来循环型社会的有效方法。较少

Water, material, energy balance were evaluated in urban and rural area. This research focused on complex of natural and artificial water where pollutant materials and energy flux flow with water cycle. First, detail water demand was evaluated for each water use on consideration with water quality. Availability of stormwater and wastewater reuse inner building or inner each urban block was estimated. In proposed estimation scheme, stormwater and wastewater quality were evaluated for reuse availability for each water use like as flushing toilets, car washing and springing garden. These estimation scheme were applied to Osaka and Tottori city area, and reduction rate of flesh water use was evaluated.Secondly, pollutant load with natural and artificial water cycle was investigated in urban and rural area. Especially, particulate pollutant load, which is important factor for water quality evaluation of availability of water reuse, was analyzed in detail. The particle size distribution of po … More llutant runoff with stormwater was observed during some rainfall events. Relatively big size of particulate pollutant load were concentrated to early time of rainfall duration. Appropriate storage time for available stormwater reuse can be evaluated as the removal rate of pollutant from storage stormwater was depended on particle size distribution. Deposit pollutant on urban surface derived from air pollution and automobile was investigated in road and roof surface. Appropriate time can be estimated because much contaminated stormwater was concentrated during less than ten minutes.Finally, solid waste treatment system was evaluated by Eco-Efficiency. The generated electricity and exhausted heat along the treatment process of municipal solid waste were calculated as effective use and service. The sludge and useless heat were calculated as the environmental pollutant load. The estimation scheme using of Eco-Efficiency was effective method in order to establish the future recycle oriented society. Less
