项目摘要

We considered that a waste treatment system and a sewage treatment system are an "Energy and resoure recycling system" in an urban area. In the recycling system, waste heat of incinerator, sewage heat energy and potential energy of sewage are recovered, digestion gas is collected and so]ar energy is collected by photovoltaie power generation, and these energy and resource are used at the two treatment system. We can deter an increase of energy consumption caused by introduction of advanced treatment technologies with the energy and resouree recycling system.At first, we examined the use of a digestion gas gonerated at a sewage treatment plant as fuel of waste collection vehicles. Case-1 is the use of methane of digestion gas as fuel of onsite "Phosphoric Acid Fuel Cell (PAFC)" and the use of electric power generated by the fuel cell for the power of electric waste collection vehicle. Case-2 is the use ofmethane of digestion gas as fuel of waste colleetion vehicle which engine is "Polym … More er Electrotype Fuel Cell (PEFC)'. Amount of the renewable energy exceed the amount of energy need to waste collection and transportation in both eases. Ratio afthe amount of renewable energy to the amount of consumed energy is 4.3 in case-1, and it is 4.7 in case-2. When we introduce co-generation system and use heat energy in case-1, then the energy efficiency of case-1 is better than case-2. If we use the electric vehicle and the fuel cell vehicle for waste collection and transportation, we can reduce Nox emission volume and Sox emission vclume very much.Next, we have examined a possibility of that the recycle and renewable energy produoed in the sewage system covered an inerease of electrie energy oonsumption caused by introduction of an advanced sewage treatment technology. About the increase of energy consumption, by introducing advanced sewage treatment, the amount of electric power consumption of the sewage treatment become 1.4 times of that of present system. About the producing of the recycle and renewable energy, we can get the electric power that is equivalent to 55% of the electricity consumptien ef the present system. The amount of electricity generated from the recycled and renewable energy at the sewage system is 1.4 times as the amount of electricity increased by introdueing of the advanced sewage treatment system. Consequently, we have indicated that we can cut down the problem of increase of electricity by introducing of the advanced sewage treatment system with the use of recycied and renewable energy at the sewage system.

我们认为，废物处理系统和污水处理系统是城市地区的“能源和资源循环系统”。该回收系统回收焚烧炉余热、污水热能和污水势能，收集消化气，并利用光能发电收集太阳能，将这些能量和资源用于两个处理系统。我们可以透过能源及资源循环再用系统，遏止因引进先进处理技术而引致的能源消耗增加。我们首先研究了利用污水处理厂产生的消化气体作为废物收集车的燃料。案例1是使用沼气中的甲烷作为现场“磷酸燃料电池”的燃料，并使用燃料电池产生的电力为电动垃圾收集车提供动力。案例2是利用沼气中的甲烷作为“聚合物”发动机垃圾收集车的燃料 ...更多信息电型燃料电池（PEFC）在这两种情况下，可再生能源的数量都超过了废物收集和运输所需的能源数量。可再生能源量与消耗能源量之比在情况-1下为4.3，在情况-2下为4.7。当我们引入热电联产系统并在情况1中使用热能时，情况1的能量效率优于情况2。如果我们使用电动汽车和燃料电池汽车进行垃圾收集和运输，我们可以大大减少NOx排放量和Sox排放量。其次，我们研究了污水系统中产生的回收和可再生能源是否可以覆盖由于引入先进的污水处理技术而导致的可再生能源消耗的增加。在能耗增加方面，通过引入先进的污水处理技术，污水处理的耗电量是现有系统的1.4倍。在再生能源的生产方面，我们可以获得相当于现有系统用电量55%的电力。污水系统中回收及可再生能源产生的电量是引入先进污水处理系统所增加电量的1. 4倍。因此，我们表示，我们可以通过在污水系统中引入先进的污水处理系统，使用可再生能源和可再生能源来减少电力增加的问题。少
