项目摘要

The word of "Metabolism" is usually used in biochemistry. All organisms grow by taking up nutritional substances and getting energy and producing cellular constituents, and by discharging waste products into outer environment. This mechanism of biochemical change and transfer of nutritional substances is called as metabolism of living organisms. It is said that a city or an urban area has much analogy with a living organism, because a urban area takes up a lot of new materials, water, energy and foods, and discharges solid wastes, wastewater, waste gas and waste heat, for the purpose of growing and/or maintaining its activities.A computer simulation model of urban sewer systems and solid wastes colletion systems is formulated by using a square grid system of 250m by 250m. The total area of the model covers 612| of the main part of Tokyo Metropolitan Area. Each grid has been recorded following information as population ; total floor area of the buildings which belong to the grid ; the t … More ypical usage types of the buildings such as residential use, commercial and shop use, office use, industrial use, hospital, and shools and public use.In the present model, the sewer system is difined as a collection system of waste heat from urban activities and optimization of heat recovery is calculated in the system. Introducing the heat pump facilities for sewage at optimum points in the urban area to supply a optimum amount of heat, the total emission of CO2 from the urban area might be minimized so far in near future. Adding sewer system, solid wastes management also have so much potential to be effective in energy recovery for the urban activities. In the present model, the amount of energy recovery from solid wastes is also estimated for each collection area which is variable depending on management policy. The price of the land along the streets is stored as basic data and the time dependent change of the price is shown on the monitor screen.It is expected to use the present simulation model for presenting an agreeable plan to both side of pros and cons to the decision of location of municipal facilities.

“代谢”一词通常用于生物化学。所有的生物体都是通过吸收营养物质、获得能量、产生细胞成分以及向外部环境排放废物来生长的。这种生化变化和营养物质转移的机制称为生物体的代谢。有人说，一个城市或一个城区很像一个生命体，因为一个城区要占用大量的新材料、水、能源和食物，还要排放固体废物、废水、废气和余热，为了增长和/本文建立了城市污水系统和固体废物收集系统的计算机模拟模型，250米乘250米模型总面积612|东京都的主要部分。每个网格都记录了以下信息：人口;属于网格的建筑物的总楼面面积; ...更多信息针对建筑物的典型使用类型，如住宅、商业和商店、办公室、工业、医院和学校以及公共用途，将下水道系统定义为城市活动余热的收集系统，并对该系统的热回收进行了优化计算。在城市最佳点引入污水热泵设施，以提供最佳热量，在不久的将来，城市地区的CO2总排放量可能会降至最低。加上下水道系统，固体废物管理也有很大的潜力，可以有效地回收城市活动的能源。在本模型中，还估计了每个收集区的固体废物能源回收量，该回收量根据管理政策而变化。将沿着土地的价格作为基础数据存储，并在监视器画面上显示价格的时间变化。期望利用本模拟模型，为市政设施选址的决策提供正反双方都能接受的方案。少
