石化行业是国民经济重要的支柱产业和基础产业,同样也是用水和污染物排放大户。近年来,水资源短缺的现状给石化行业的发展带来了严峻的挑战,同样大量的石化废水排放对环境造成了威胁,废水排放标准愈来愈严格,这也给石化废水处理带来了沉重的压力。化工污水中酸碱性含量高,成分复杂,如果不经过处理直接排放入江河湖海中,对水资源污染十分严重。水源流经的土地也会造成一定的腐蚀 The petrochemical industry is an important pillar industry and basic industry of the national economy. It is also a major emitter of water and pollutants. In recent years, the current situation of water shortages has brought severe challenges to the development of the petrochemical industry. Similarly, the discharge of large amounts of petrochemical wastewater poses a threat to the environment. Wastewater discharge standards have become increasingly stringent. This has also brought heavy treatment to petrochemical wastewater. pressure. Chemical wastewater has high acid and alkaline contents and complex components. If it is discharged directly into rivers, lakes, and seas without treatment, the pollution to water resources is very serious. Water flowing through the land will also cause some corrosion
