| 石油化工废水指的是由石油化工厂排放的废水。其废水的水量大，除生产废水外，还有冷却水及其他用水；废水的组分复杂，因石油化工产品繁多，反应过程和单元操作复杂，废水性质复杂多变；废水中有机物特别是烃类及其衍生物含量高，并含有多种重金属。在加快发展石油化工工业的过程中，必须高度重视污染防治工作，这对石油化工工业可持续发展具有十分重要的意义。 Petrochemical wastewater refers to wastewater discharged by petrochemical plants. Its wastewater has a large amount of water, besides the production wastewater, there are cooling water and other water; the composition of wastewater is complex, because of the variety of petrochemical products, the complex reaction process and unit operation, and the complex and changeable nature of wastewater; the content of organic substances, especially hydrocarbons and their derivatives, is high, and contains a variety of heavy metals. In the process of accelerating the development of petrochemical industry, we must attach great importance to pollution prevention and control, which is of great significance to the sustainable development of petrochemical industry. |
