本研究考虑2种情境提升原有都市水资源回收中心为绿色加气站,设置“绿色加气站”(含“甲烷供应系统”及“绿色氢供应系统”)与“绿色加电站”.故变更本水资源处理流程,分2种构想.构想1,将园区周边高浓度有机废水做为本处理厂水来源之一,或采用高低浓度废水分流收集方式,废水处理系统则采用两相式厌氧处理系统,以废水及污泥产制氢气及甲烷气成为气态生质能源.构想2,于现有规划设计增设新型有机污泥处理设施,包含高温好氧消化系统及甲烷化系统,可以直接生产甲烷气.另外,可于场址顶部设计太阳能丛林,产生之电力直接供应园区用电,或将处理出流水电解产生氢气燃料.本研究以污水处理量18 000CMD计算可产生之气体燃料,并换算至现有压缩天然气(CNG)公交车、电动车以及氢能汽车所需气体燃料量进行效益分析,若废水处理流程更改为构想1,每日所产生之氢气可供应250部氢能车使用,同时产生的甲烷气体可供应50部CNG公交车使用,若氢气透过燃料电池发电可供应378车次的电动车充电,但此方案必须导入园区周边的高浓度有机废水,将废水COD浓度提高至5g/L才能有效实行.构想2,在不更动现有的水资源回收处理程序设计下,仅在程序中增加有机污泥能源化系统,每日产制出的甲烷气体可供应20部CNG公交车使用,并降低系统污泥产生量达80%,不仅可达到能源回收的目的亦可降低污泥处置成本.最后若于水资源处理中心建物顶端设置太阳能板丛林,所产生的电力可供应园区使用,或可提供电动车加电站使用,每日可补充22车次的电动车.透过设置放流水电解系统,每日可供应7部氢能车使用;设置太阳能发电及电解系统,不仅可提升水回收比例,更具有展示及美化功能.
This research considers two kinds of situations to upgrade the original urban water resources recovery center as a green filling station, and set up a “green filling station” (including “methane supply system ” and “green hydrogen supply system ”) Therefore, there are two kinds of conceptions to change this water treatment process.Concept 1, using high concentration organic wastewater around the park as one of the sources of water for this treatment plant, or using the collection method of high and low concentration wastewater, waste water The treatment system uses a two-phase anaerobic treatment system to generate hydrogen and methane gas from the waste water and sludge as a gaseous biomass energy. Concept 2. In the existing planning and design, a new organic sludge treatment facility, including high-temperature aerobic digestion System and methanation system, which can directly produce methane gas. In addition, the solar jungle can be designed at the top of the site, the generated electricity can directly supply the park electricity or will process the outflow electrolysis to produce hydrogen fuel. In this study, the sewage treatment capacity of 18 000 CMD Calculate the amount of gas fuel that can be produced and convert it to the existing compressed natural gas (CNG) buses, electric vehicles and hydrogen fuel vehicles for benefit analysis. If the wastewater treatment process is changed to Concept 1, the daily generated hydrogen It can supply 250 hydrogen cars and produce methane gas for 50 CNG buses. If hydrogen can be supplied through fuel cells, 378 trips of electric vehicles can be charged, but this solution must be imported into the high concentration organic Wastewater, the wastewater COD concentration increased to 5g / L can effectively implement.Concept 2, without changing the existing water recycling program design, only the program to increase organic sludge energy system, produced daily Methane gas can be used by 20 CNG buses and reduce the amount of sludge generated by the system up to 80%, not only for the purpose of energy recovery but also for sludge disposal costs. Finally, if a solar panel jungle is installed at the top of the water treatment center , The generated electricity can be supplied to the park or can be used by electric vehicles and power stations to replenish 22 vehicles per day. By setting up a water electrolysis system, 7 hydrogen vehicles can be used daily. Solar energy Power generation and electrolysis systems not only enhance the proportion of water recovery, but also display and beautify functions.
