Abstract
At present, the main trend of China’s economic development is “Green, high-quality development”, which is to sustainably grasp the relationship between development and environmental protection. Recently, Hunan Province has implemented the strategic goal of a strong ecological province and taken multiple measures to promote green and low-carbon development. Based on the ecological environment statistics from 2020 to 2022, this study analyzed the wastewater pollutants in Hunan Province. The results showed that compared with 2020 and 2021, the emissions of chemical oxygen demand and ammonia nitrogen from industrial and domestic sources continued to decrease in 2022, indicating that the emission reduction work had achieved remarkable results. The cities with the highest chemical oxygen demand emissions were Shaoyang, Yongzhou and Zhuzhou respectively. The cities with the highest ammonia nitrogen emission were Chenzhou, Yueyang and Zhuzhou. Therefore, the relevant countermeasures and suggestions were put forward.
