To address the controversial issue of implementing emission standards for biogas generator sets, we first need to clarify the working principle of biogas generator sets? Due to the social and economic benefits of biogas power generation projects, the use of biogas power generation units for grid connection generally adopts reciprocating gas internal combustion unit power generation technology with smaller single unit power. Through the combustion of biogas in the cylinder, the piston movement is driven to generate power, which then drives the generator to operate and generate electricity.

燃气内燃机组发电技术具有如下特点：

The gas internal combustion unit power generation technology has the following characteristics:

①单位千瓦建站投资少，2500~3500元/kW；投资回报率高：45%~80%；运行成本低：0.1~0.12元/kWh。

① Low investment per kilowatt for station construction, ranging from 2500 to 3500 yuan/kW; High investment return rate: 45%~80%; Low operating cost: 0.1-0.12 yuan/kWh.

②燃气内燃机机组配套设备简单，电站可移动性强。

② The supporting equipment of the gas internal combustion engine unit is simple, and the power station has strong mobility.

③机组单机功率范围：4kW~2000kW，可以单台工作，也可多台并网，建站灵活。

③ The single unit power range of the unit is 4kW~2000kW, which can operate as a single unit or connect multiple units to the grid, making station construction flexible.

④电站自耗电少，不超过发电量的2%。

④ The self consumption of the power station is low, not exceeding 2% of the power generation.

⑤燃气内燃及采用热电冷联供，机组热效率可达80%。

⑤ Gas internal combustion and the use of combined heat, power, and cooling can achieve a thermal efficiency of up to 80% for the unit.

⑥对沼气气源条件要求较低。

⑥ Low requirements for biogas source conditions.

目前各地环境影响评价和环保验收的排放指标主要是SO2和NOx各地执行的标准主要有以下几个：

At present, the emission indicators for environmental impact assessment and environmental acceptance in various regions mainly include SO2 and NOx. The standards implemented in various regions mainly include the following:

①《锅炉大气污染排放标准》

① Emission Standard for Air Pollution from Boilers

②《火电厂大气污染物排放标准》(GB 13223—

② Emission Standards for Air Pollutants from Thermal Power Plants (GB 13223-

③《车用点燃式发动机及装用点燃式发动机汽车排放污染物排放限值及测量方法》(GB 14762-2002)第二阶段与《车用压燃式、气体燃料点燃式发动机与汽车排气污染物排放限值及测量方法(Ⅲ、Ⅳ、Ⅴ阶段)》

③ The second stage of GB 14762-2002 "Limits and Measurement Methods for Pollutant Emissions from Automotive Positive Ignition Engines and Vehicles Equipped with Positive Ignition Engines" and "Limits and Measurement Methods for Pollutant Emissions from Automotive Compression Ignition and Gas Fuel Positive Ignition Engines and Vehicles (China III, IV, V stages)

④《大功率沼气发电机组》

④ High power biogas generator set

⑤《大气污染物综合排放标准》(GB 16297－。

⑤ Comprehensive Emission Standards for Air Pollutants (GB 16297-).
