沼氣發(fā)電機組的排放標準因地區(qū)、機組類型和應(yīng)用場景不同而有所差異，以下是主要的排放標準及適用情況：

　　The emission standards for biogas generators vary depending on the region, unit type, and application scenario. The following are the main emission standards and their applicable situations:

　　1.《大氣污染物綜合排放標準》（GB 16297-1996）

　　1. Comprehensive Emission Standards for Air Pollutants (GB 16297-1996)

　　適用于沒有行業(yè)特定標準的廢氣排放源，對二氧化硫（SO?）、氮氧化物（NOx）、顆粒物等污染物的排放濃度和速率作出規(guī)定。

　　Applicable to exhaust gas emission sources without industry-specific standards, regulations are made on the emission concentration and rate of pollutants such as sulfur dioxide (SO?), nitrogen oxides (NOx), particulate matter, etc.

　　例如，SO?排放濃度限值為：新污染源一級標準960mg/m?，二級標準500mg/m?；現(xiàn)有污染源一級標準1200mg/m?，二級標準700mg/m?。

　　For example, the emission concentration limit for SO is 960mg/m according to the first level standard for new pollution sources? Secondary standard 500mg/m?; The current primary standard for pollution sources is 1200mg/m? The second level standard is 700mg/m?.

　　2.《車用壓燃式、氣體燃料點燃式發(fā)動機與汽車排氣污染物排放限值及測量方法》（GB 17691-2005）

　　2. "Limits and Measurement Methods for Exhaust Pollutants from Compression Ignition and Gas Fuel Ignition Engines for Vehicles" (GB 17691-2005)

　　若沼氣發(fā)電機組采用類似汽車發(fā)動機的技術(shù)路線，可參照該標準的中國Ⅲ、Ⅳ、Ⅴ階段排放限值。

　　If the biogas generator set adopts a technology route similar to that of a car engine, the emission limits for stages III, IV, and V in China can be referred to in this standard.

　　例如，NOx排放限值在Ⅳ階段為2.0g/kWh，Ⅴ階段為1.0g/kWh（具體限值因發(fā)動機類型和功率有所不同）。

　　For example, the NOx emission limit is 2.0g/kWh in Stage IV and 1.0g/kWh in Stage V (specific limits vary depending on engine type and power).

　　3.《大功率沼氣發(fā)電機組》（GB/T 29488-2013）

　　3. High power biogas generator sets (GB/T 29488-2013)

　　適用于額定功率不小于250kW、以沼氣為主要燃料的往復式內(nèi)燃機驅(qū)動的交流工頻發(fā)電機組。

　　Suitable for AC power frequency generator sets driven by reciprocating internal combustion engines with a rated power of not less than 250 kW and mainly fueled by biogas.

　　規(guī)定機組在額定工況時NOx排放限值為3.48g/kWh，對SO?排放未作具體規(guī)定。

　　The NOx emission limit for the unit under rated operating conditions is set at 3.48g/kWh, but there is no specific regulation on SO? Emissions.

　　4.地方標準

　　4. Local standards

　　部分地區(qū)制定了區(qū)域性大氣污染物綜合排放標準，如山東省《區(qū)域性大氣污染物綜合排放標準》（DB37/2376-2019），對NOx、SO?、顆粒物等污染物設(shè)定更嚴格的排放限值，具體數(shù)值因地區(qū)和污染控制要求而異。需注意，不同地區(qū)的環(huán)保部門可能根據(jù)當?shù)丨h(huán)境質(zhì)量狀況和管理需求，要求沼氣發(fā)電項目執(zhí)行更嚴格的排放標準或補充特定污染物的監(jiān)測要求。建議項目單位在建設(shè)前咨詢當?shù)厣鷳B(tài)環(huán)境部門，明確適用的排放標準和監(jiān)管要求。

　　Some regions have established regional comprehensive emission standards for air pollutants, such as the Shandong Province's "Regional Comprehensive Emission Standards for Air Pollutants" (DB37/2376-2019), which address NOx and SO emissions? Strict emission limits are set for pollutants such as particulate matter, and the specific values vary depending on the region and pollution control requirements. It should be noted that environmental protection departments in different regions may require biogas power generation projects to implement stricter emission standards or supplement monitoring requirements for specific pollutants based on local environmental quality conditions and management needs. It is recommended that the project unit consult the local ecological environment department before construction to clarify the applicable emission standards and regulatory requirements.
