Anaerobic biogas generator NOx treatment, not only solve environmental problems, but also produce a large amount of electricity and heat energy, effectively reduce the greenhouse effect, reduce pollution to the environment, but also power generation for rural areas, provide a new way of development, create more economic and social benefits.

Anaerobic biogas power generation is a new comprehensive energy utilization technology that integrates energy saving and environmental protection. Anaerobic biogas power generation technology is the use of a large number of organic waste in life, the anaerobic fermentation of biogas generated by the treatment of biogas, drive biogas generating units to generate electricity, electricity and heat energy, is an important way to effectively use anaerobic biogas, anaerobic biogas power generation has the effect of energy saving, environmental protection and safety.

The nitrogen oxide in the exhaust gas of biogas generator set is mainly composed of nitric oxide, NO and NO2. Its composition and concentration are different, and it has different degrees of toxicity, which seriously endangers human health and ecological environment. The SCR denitrification technology adopted by Green Valley Environmental Protection has rich project experience in biogas power generation fields such as landfill, amylator, sewage plant, fertilizer plant, livestock farm, food and kitchen waste landfill, etc. The denitrification efficiency has reached more than 95%, meeting the national emission requirements at the same time. It can also monitor the actual emission data in real time according to different project sites and units, and choose effective technical solutions to solve problems.

For the exhaust gas of biogas generator set, we choose the selective catalytic reduction technology (SCR denitrification) to control the NOx in the exhaust gas of biogas generator. Urea or NH3 is used as the reducing substance, and under the action of a certain stability and catalyst, NOx can be reduced without first reacting with O2. For NH3, a certain proportion of ammonia escape catalyst is coated on the end of SCR carrier to ensure that NH3 reacts with O2 to produce N2 and H2O to avoid secondary pollution caused by NH3 leakage.
