摘要:污水處理過程因高耗能以及直接溫室氣體排放，使得逼近碳中和運(yùn)行勢在必行。然而，污水處理多以追求能源中和（Energy neutrality）為目的，且常與碳中和（Carbon neutrality）概念混為一談。通過歐洲3個不同污水處理廠實例，直觀解釋并說明能源中和與碳中和的不同。實際運(yùn)行案例表明，實現(xiàn)能源中和并不意味著同時可以實現(xiàn)碳中和，而如果實現(xiàn)碳中和則可以認(rèn)為也同時實現(xiàn)了能源中和。這是因為污水處理過程中除能源消耗的間接碳排放外，還會在處理過程中直接產(chǎn)生NxO、CH4、VOCs等溫室氣體（從COD轉(zhuǎn)化的CO2因大多為生源性，所以不計入碳排放清單）。此外，各種化學(xué)藥劑（如碳源、除磷藥劑等）的生產(chǎn)與運(yùn)輸過程也會間接產(chǎn)生CO2等溫室氣體。廠外植樹造林、風(fēng)力發(fā)電、外源有機(jī)物厭氧共消化固然有助于污水處理廠實現(xiàn)碳中和，但這些方式并非污水處理廠分內(nèi)之事，應(yīng)該都是“偽中和”。其實，污水處理廠要想同時實現(xiàn)能源中和與碳中和，只有深入挖掘污水余溫?zé)崮芊侥軐崿F(xiàn)。
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.
