Illustration depicting the increased water demand in megacities based on urban population growth from 1950 to 2025. 大都市水资源在1950至2025年间随城市人口增长的增长曲线图。


A figure, illustrating the dramatic daily increase in population, based on the example city of Qingdao. Every day, Qingdao grows by 312 people. That leads to the daily increased demand of drinkwater of 34m³. In addition, garbage collection increases by 0.3 tons every day. Due to this, there is high pressure on the industry for waste treatment and water purification. 青岛市单日水资源需求增长示意图。青岛市人口数量每天会增加312人,这会产生34立方米饮用水的增长需求,并会每天产生0.3吨的垃圾。这将给垃圾处理和水净化带来非常严峻的挑战。


Central infrastructure systems have handled wastewater disposal in metropolitan areas up until now. During this process, a central sytem collects wastewater from millions of people. Enormous sewer diameters, long transport routes, and many pumps are required for this process. 迄今为止,大都市一般均采用集中式基础排污系统进行污水排放处理。该集中式基础排污系统需处理上百万人所产生的废水。为了能够实现这一目标,系统所配管道的直径必须足够大,排水沟必须足够长,并需提供大量水泵(组)。


Major facilites for waste water treatment, primarily built outside of cities, demand long planning times and high investment costs. Central systems also rely on a strict separation of water supply, wastewater treatment and waste treatment, so that a circulation flow is difficult, or not even possible. 在远离居住人口密集区的位置安装大型污水排放设备,往往需要投入大量时间和资金。集中式系统会将供水系统,污水净化以及垃圾处理进行严格分离,防止发生任何物料循环的现象。


The semicentral approach of a supply and treatment centre (STC) relies on medium-sized units. The diagram explains how this is accompanied by smaller sewer diameters, shorter transport routes and fewer pumps. The smaller scale reduces the planning time and total investment costs. 较之大型集中式基础排污系统或者非集中式供水解决方案,供水排污中心(STC)的半集中式理念,其污水处理单元极小,或者仅为中等大小。如图所示,如果采用这种方案,所需管道的直径较小,排水沟较短,所需水泵的数量较少。凭借这一较小的规模,可以降低设计时间和投资成本。


It also involves an integrated infrastructure approach which treats the water, waste water, waste products and produces energy in a systemic way. This enables, for example, the separation of slightly contaminated grey- and blackwater and their separate, resourcesaving processing and reuse (details in the next diagram). 除此之外,半集中式系统还是一种综合性基础设施处理方案,其将水,污水,垃圾以及能源进行循环处理。比如,通过对饮用水,轻微污染的灰水及黑水的分离处理,实现了独立的后续处理和后续使用,并能够达到节约资源的目的。(详见下一图)


This modular and integrated approach creates a system with high flexibility, adaptability, improved resources and energy efficiency. 这种模块化的综合解决方案建立了一个具有高度灵活性和适应性,并且能够优化资源和能源使用效率的系统。
