摘要:汙水處理过程因高耗能以及直接溫室氣體排放，使得逼近碳中和运行势在必行。然而，汙水處理多以追求能源中和（Energy neutrality）为目的，且常与碳中和（Carbon neutrality）概念混为一谈。通过欧洲3个不同汙水處理厂实例，直观解释并说明能源中和与碳中和的不同。实际运行案例表明，实现能源中和并不意味着同时可以实现碳中和，而如果实现碳中和则可以认为也同时实现了能源中和。这是因为汙水處理过程中除能源消耗的间接碳排放外，还会在处理过程中直接产生NxO、CH4、VOCs等溫室氣體（从COD转化的CO2因大多爲生源性，所以不計入碳排放清單）。此外，各種化學藥劑（如碳源、除磷藥劑等）的生産與運輸過程也會間接産生CO2等溫室氣體。厂外植树造林、风力发电、外源有机物厌氧共消化固然有助于汙水處理厂实现碳中和，但这些方式并非汙水處理厂分内之事，应该都是“伪中和”。其实，汙水處理厂要想同时实现能源中和与碳中和，只有深入挖掘污水余溫熱能方能实现。
Abstract:Due to the high energy consumption and direct greenhouse gases (GHGs) emission, carbonneural operation of wastewater treatment process has become imperative. However, energy neutrality of wastewater treatment plants (WWTPs) is often pursued, which is easily confused with the concept of carbon neutrality. With this study, three different European WWTPs are utilized to elucidate the difference between energy neutrality and carbon neutrality. The case studies indicate that achieving energy neutrality does not mean that carbon neutrality can be realized at the same time. Reversely, energy neutrality should be simultaneously realized if carbon neutrality is achieved. This is because there are also direct GHGs like NxO, CH4, and VOCs during the treatment process (biogenic CO2 converted from COD is not included in the carbon emission inventory), besides indirect carbon emissions from energy consumption. Furthermore, both production and transportation of chemicals (such as carbon sources, chemical phosphorus agents, etc.) can indirectly generate GHGs. Afforestation, wind power, and anaerobic co-digestion with exogenous organics can certainly contribute to carbon neutrality for WWTPs, but these measures are usually conducted outside WWTPs so that they should be called as “pseudo-neutrality”. In fact, simultaneously achieving energy neutrality and carbon neutrality for WWTPs can be only accomplished under the condition of utilizing thermal energy.
