The invention relates to an environment-friendly arc wind tunnel nitric oxide tail gas treatment device and method. The device comprises a buffer tank, a multi-level spraying tower, a delisted, a waste liquid utilizing device and a tail gas exhaust device; each layer of the multi-level spraying tower is provided with a plurality of nozzles, and a potassium hydroxide solution is sprayed out throughthe nozzles to be atomized. A KOH solution is adopted as an absorbent, spraying of the KOH solution can adapt to tail gas ingredients and flow fluctuations, the high-concentration nitric oxide can beefficiently removed and converted into the KNO3 solution to be directly adopted as liquid fertilizer for garden afforesting, environment-friendly nitric oxide removal is achieved, the resource utilization rate is increased, a waste liquid processing system is omitted, the building cost is saved, and arc wind tunnel nitric oxide tail gas environment-friendly treatment can be achieved. 本发明涉及种绿色环保的电弧风洞氮氧化物尾气处理装置及处理方法。所述装置包括缓
