水資源回收中心除水資源外另有能源及資源等過去忽略之可回收能資源再利用，其可扮演節能、創能及資源循環再生具附加價值再利用之角色，國外已漸朝能資源整合之方向規劃設計及操作維護方式加以管理，創造能資源整合型環境友善之水資源回收中心，本計畫成立目的為蒐集國內水資源回收中心案例參考評估規畫，提出開發能資源整合循環型水資源回收中心之經濟決策分析與評估規劃。

Water scarcity is bound to be a key global issue in view of the multifaceted global climate change and unevenly distributed rainfall. The development of new water resources is an international trend, and the water resource recycling center is regarded as an important emerging water source in Taiwan. It is expected that 1.32 million tons water will be supplied to industrial water supply every day in 2031 year, which will ease the pressure to develop traditional water sources. Although water resource recycling center can provide stable water supply and good water quality, the more energy consumption of water resource recycling center has become a new environmental problem. At present, renewable energy such as solar/wind power, small water and bio-energy has been successfully imported into water resource recycling center in other foreign countries. In addition, the sludge recycling technologies including sludge digestion and gas generation, fuel of thermal power plants, compost, biogas production have been developed in water resource recycling center. There are also successful cases of recycling nitrogen, phosphorus and other nutrients in waste water treatment plants as well as various rare and valuable elements. In this project, the visit of foreign water resource recycling center, the cases collection, the evaluation principle of innovative comprehensive recycling center have been conducted. And submission to foreign seminars, expert discussion, education training and interministerial research have been completed. 50 domestic water resource recycling centers have been investigated, which includes general sewage and industrial areas/science park water resource recycling centers. We chose 20 potential water resource center to carry out the real plant visit, and combine with the renewable water to promote the policy implementation. We hope to build a new creative energy recycling center with the capacity, water and energy conservation. The plan has established a mechanism for continuous improvement of the water resource recycling center and completed the Sustainable Circular-Efficiency Indicator (SCI), considering the three sustainable recycling elements of water resources, energy and resources. The corresponding evaluation items of this SCI are Water regeneration rate, energy self-sufficiency rate and resource regeneration rate. The three evaluation items are multiplied by their corresponding weights, and the index of SCI’s sustainable cycle efficiency is obtained. The weight planning is determined by the net economic value, which assists the water resource recycling center to upgrade from the perspective of industrialization. The plan has completed the evaluation of SCI index of domestic water resource recycling center. At present, the SCI sustainable recycling efficiency index of the water resource recycling center is orderly ungraded (to be tried), copper, silver, gold, and diamond-level for fully recycled water resource regeneration center. The results show that each plant needs to strengthen the resource category and industrialization direction, and the current situation of energy recycling, renewable resources and renewable water in this plant have been analyzed. The proposed improvement plan can further help to build the innovation energy type full recovery water resource regeneration center. The project has completed the calculation of SCI index of water resource recycling center in north central south area (taoyuan north district, taichung and tainan anping). The index score of SCI is 64 in the north of taoyuan, 67.5 in taichung and 66.5 in taian, and the current 3 plants are all silver - grade indicators because of high water regeneration rate. In order to build a renewable energy recycling center, we need to make efforts in energy conservation, energy utilization, resources recycling and water resource application. The strategy is orderly to check the electricity consumption of the factory, import the energy saving facilities, utilize the location characteristics to develop the renewable energy, and reduce the moisture content of the sludge as well as expanding resources recycling pipeline and match-filtering reclaimed water potential users. It is expected to build a water resources recycling center with capacity, water production, energy saving and other functions, which will promote water conservancy industry taking a big step towards carbon neutrality.
