The water pollution accident in environmental engineering is a sudden, multifaceted, unorganized and destructive accident. However, with the rapid development of social production, the rapid development of industrialization has led to more and more pollution accidents, which has a significant impact on the local ecological environment and residents. Virtual reality (VR) technology can conduct virtual simulation of water pollution accidents, and timely monitor and eliminate water pollution accidents. This paper introduced the significance of environmental protection engineering and VR technology, and used OpenGL to simulate the virtual scene of water pollution accidents in environmental engineering. Firstly, three-dimensional (3D) scene simulation was carried out, then numerical simulation was carried out according to the characteristics of wastewater discharge. Finally, the entity and background were drawn to complete the virtual simulation of water pollution accidents. The experimental part used the water pollution accident virtual scene to treat the sewage, and compared it with the real water pollution situation. The experimental results showed that the virtual simulation scene can effectively reduce the COD (Chemical Oxygen Demand) content in the sewage and improve the water quality grade. The COD content in the sewage was reduced from 18.4mg/L to 13.9mg/L, and the water quality was greatly improved.
