　　Shocking! Five recycled water plants in Beijing are connected to the grid for power generation, and the gas-fired generator unit reduces carbon dioxide emissions by 42000 tons annually

　　近日，小紅門再生水廠沼氣發(fā)電項(xiàng)目順利并網(wǎng)發(fā)電，這一里程碑事件標(biāo)志著高碑店、高安屯等北京5座再生水廠全面實(shí)現(xiàn)沼氣并網(wǎng)發(fā)電，構(gòu)建起規(guī)模化生物質(zhì)能源利用體系。據(jù)悉，5座水廠燃?xì)獍l(fā)電機(jī)組總裝機(jī)容量達(dá)25.6兆瓦，年發(fā)電量預(yù)計達(dá)7000萬度，可實(shí)現(xiàn)年減排二氧化碳4.2萬噸，既是北京推進(jìn)污水處理行業(yè)甲烷綜合利用、加強(qiáng)污泥厭氧消化沼氣回收的重點(diǎn)成果，更是燃?xì)獍l(fā)電機(jī)組助力低碳治水、推動污泥資源化轉(zhuǎn)化的生動實(shí)踐。

　　Recently, the Xiaohongmen Reclaimed Water Plant's biogas power generation project was successfully connected to the grid for power generation. This milestone event marks the comprehensive implementation of biogas grid connected power generation in five Beijing reclaimed water plants, including Gaobeidian and Gao'antun, and the construction of a large-scale biomass energy utilization system. It is reported that the total installed capacity of gas power generation units in five water plants reaches 25.6 megawatts, with an expected annual power generation of 70 million kilowatt hours, which can achieve an annual reduction of 42000 tons of carbon dioxide emissions. This is not only a key achievement in promoting the comprehensive utilization of methane in the sewage treatment industry and strengthening the anaerobic digestion and biogas recovery of sludge in Beijing, but also a vivid practice of gas power generation units to help low-carbon water treatment and promote the transformation of sludge resources.

　　很多人疑惑，再生水廠為何要投入燃?xì)獍l(fā)電機(jī)組進(jìn)行沼氣發(fā)電？核心答案在于“變廢為寶、綠色循環(huán)”。再生水廠污水處理過程中會產(chǎn)生大量污泥，若處理不當(dāng)不僅會成為環(huán)境負(fù)擔(dān)，其厭氧消化產(chǎn)生的沼氣若直接排放，還會加劇溫室效應(yīng)。而燃?xì)獍l(fā)電機(jī)組的投入使用，恰好破解這一難題，以小紅門再生水廠為例，其安裝的4臺燃?xì)鈨?nèi)燃發(fā)電機(jī)組，以污泥厭氧消化產(chǎn)生的沼氣為燃料，實(shí)現(xiàn)能源梯次利用，兼具高效、節(jié)能、環(huán)保、經(jīng)濟(jì)的多重優(yōu)勢。

　　Many people wonder why recycled water plants need to invest in gas-fired generators for biogas power generation? The core answer lies in "turning waste into treasure and promoting green circulation". During the sewage treatment process of a reclaimed water plant, a large amount of sludge will be generated. If not treated properly, it will not only become an environmental burden, but also exacerbate the greenhouse effect if the biogas produced by anaerobic digestion is directly discharged. The use of gas-fired generator sets has precisely solved this problem. Taking Xiaohongmen Reclaimed Water Plant as an example, the four gas-fired internal combustion generator sets installed use biogas produced by anaerobic digestion of sludge as fuel to achieve energy cascade utilization, with multiple advantages of high efficiency, energy conservation, environmental protection, and economy.

　　燃?xì)獍l(fā)電機(jī)組的高效運(yùn)轉(zhuǎn)，離不開一套“吃干榨凈”的綠能循環(huán)體系。污泥經(jīng)濃縮、預(yù)脫水、熱水解等環(huán)節(jié)處理后，送入?yún)捬跸?，微生物分解污泥中的有機(jī)物產(chǎn)生沼氣，再通過配套的沼氣脫硫、增壓預(yù)處理系統(tǒng)，去除雜質(zhì)后轉(zhuǎn)化為高品質(zhì)燃料，為燃?xì)獍l(fā)電機(jī)組提供穩(wěn)定動力。發(fā)電機(jī)組發(fā)電后，產(chǎn)生的高溫?zé)煔庥酂峥勺鳛檎羝仩t熱媒，承擔(dān)廠區(qū)采暖和蒸汽負(fù)荷，冷卻水則用于加熱采暖回水和生產(chǎn)補(bǔ)水，真正實(shí)現(xiàn)“發(fā)電+供熱”的熱電聯(lián)供模式，讓能源得到最大化利用。

　　The efficient operation of gas-fired power generation units relies on a "clean and efficient" green energy cycle system. After being treated through processes such as concentration, pre dehydration, and hydrothermal hydrolysis, the sludge is sent to an anaerobic digestion tank. Microorganisms decompose the organic matter in the sludge to produce biogas, which is then processed through a supporting biogas desulfurization and pressure boosting pretreatment system to remove impurities and convert it into high-quality fuel, providing stable power for gas generators. After the generator set generates electricity, the high-temperature flue gas waste heat generated can be used as a heat medium for steam boilers to bear the heating and steam loads in the plant area. The cooling water is used to heat the heating return water and production makeup water, truly realizing the "power generation+heating" cogeneration mode and maximizing energy utilization.

　　作為項(xiàng)目核心裝備，燃?xì)獍l(fā)電機(jī)組不僅實(shí)現(xiàn)了污泥的資源化轉(zhuǎn)化，更筑牢了環(huán)保防線。為確保排放達(dá)標(biāo)，項(xiàng)目配套建設(shè)沼氣脫硫預(yù)處理系統(tǒng)和尾氣脫硝處理系統(tǒng)，將污染物“攔在源頭”，嚴(yán)格遵循《火電廠大氣污染物排放標(biāo)準(zhǔn)》（GB 13223—2003）相關(guān)要求，確保廢氣排放合規(guī)，既避免了甲烷直接排放的溫室效應(yīng)，又守護(hù)了生態(tài)環(huán)境，實(shí)現(xiàn)從“環(huán)境負(fù)擔(dān)”到“綠色資源”的轉(zhuǎn)變。

　　As the core equipment of the project, the gas generator set not only realizes the resource conversion of sludge, but also strengthens the environmental protection defense line. To ensure emissions meet standards, the project is equipped with a biogas desulfurization pretreatment system and a tail gas denitrification treatment system, which will "block pollutants at the source" and strictly comply with the relevant requirements of the "Emission Standards for Air Pollutants from Thermal Power Plants" (GB 13223-2003) to ensure compliance with waste gas emissions. This not only avoids the greenhouse effect of direct methane emissions, but also protects the ecological environment, achieving a transition from "environmental burden" to "green resources".

　　北京5座再生水廠的實(shí)踐，充分彰顯了燃?xì)獍l(fā)電機(jī)組在市政環(huán)保領(lǐng)域的核心價值。目前，北京排水集團(tuán)已為這5座水廠構(gòu)建起全鏈條污泥資源化處置體系，日處理污泥能力達(dá)6128噸，實(shí)現(xiàn)中心城區(qū)污泥100%無害化處理，成為全國污水處理行業(yè)生物質(zhì)能源利用的標(biāo)桿。除沼氣發(fā)電外，集團(tuán)還同步布局光伏發(fā)電，構(gòu)建“光沼互補(bǔ)”綠能體系，7座光伏發(fā)電設(shè)施年發(fā)電量約3800萬度，與燃?xì)獍l(fā)電機(jī)組協(xié)同發(fā)力，進(jìn)一步提升能源自給能力。

　　The practice of five recycled water plants in Beijing fully demonstrates the core value of gas-fired power generation units in the field of municipal environmental protection. At present, Beijing Drainage Group has established a full chain sludge resource disposal system for these 5 water plants, with a daily sludge processing capacity of 6128 tons, achieving 100% harmless treatment of sludge in the central urban area and becoming a benchmark for biomass energy utilization in the national sewage treatment industry. In addition to biogas power generation, the group is also simultaneously laying out photovoltaic power generation and building a "light biogas complementary" green energy system. Seven photovoltaic power generation facilities have an annual power generation capacity of about 38 million kWh, and work together with gas-fired power generation units to further enhance energy self-sufficiency.

　　據(jù)了解，5座再生水廠的燃?xì)獍l(fā)電機(jī)組所發(fā)電量全部接入廠區(qū)10kV電網(wǎng)，專供水廠日常生產(chǎn)用電，大幅降低外購電比例，既減少了企業(yè)能源成本，又增強(qiáng)了能源供應(yīng)的穩(wěn)定性。這種“污泥變能源、余熱變溫暖”的閉環(huán)模式，不僅延伸了污泥處理綠色產(chǎn)業(yè)鏈條，更推動北京治水從“治污”向“用水”“節(jié)水”深度延伸，助力首都綠色低碳轉(zhuǎn)型。

　　It is reported that the power generation capacity of the gas generator units in the five reclaimed water plants is all connected to the 10kV power grid in the factory area, which is dedicated to supplying daily production electricity to the plants, significantly reducing the proportion of purchased electricity. This not only reduces the energy cost of enterprises, but also enhances the stability of energy supply. This closed-loop model of "turning sludge into energy and waste heat into warmth" not only extends the green industry chain of sludge treatment, but also promotes the deep extension of Beijing's water treatment from "pollution control" to "water use" and "water conservation", helping the capital's green and low-carbon transformation.

　　燃?xì)獍l(fā)電機(jī)組的規(guī)模化應(yīng)用，為市政污水處理行業(yè)的資源化、低碳化發(fā)展提供了可復(fù)制、可推廣的范本。其不僅能有效解決污泥處理和沼氣排放難題，更能實(shí)現(xiàn)能源循環(huán)利用、降低碳排放，契合我國“雙碳”目標(biāo)導(dǎo)向。未來，隨著綠色低碳理念的深入推進(jìn)，燃?xì)獍l(fā)電機(jī)組將在更多環(huán)保、工業(yè)領(lǐng)域發(fā)揮作用，為構(gòu)建閉環(huán)式水環(huán)境治理與資源利用體系注入強(qiáng)勁動力。

　　The large-scale application of gas-fired power generation units provides a replicable and promotable model for the resource utilization and low-carbon development of the municipal sewage treatment industry. It can not only effectively solve the problems of sludge treatment and biogas emissions, but also achieve energy recycling and reduce carbon emissions, which is in line with China's "dual carbon" goal orientation. In the future, with the deepening of green and low-carbon concepts, gas-fired power generation units will play a role in more environmental protection and industrial fields, injecting strong impetus into the construction of a closed-loop water environment governance and resource utilization system.
