摘要
煤化工项目在生产和运营过程中可能对地下水环境产生污染,而国内相关的具有针对性的研究还相对较少。煤化工项目组成一般包括厂区和厂外区,对地下水的污染主要来源于厂区生产区及场外灰渣场的固体污染物,和厂区生产区及厂外事故水池、蒸发池的液体污染物;污染源类型包括点源、线源和面源;污染因子包括盐类、重金属、氨、酚、COD等。正确识别煤化工项目地下水环境影响因素对开展地下水环境监测以及防治措施都有着重要意义。
Coal chemical industry may cause groundwater pollution during its producing and operating process, while little research has been carried out. Usually a coal chemical plant consists of plant area and outside-plant area, which produces poisonous solid and liquid waste, causing pollution in kind of point source, line source and area source, including pollutants such as salts, heavy metals, ammonia, phenols, COD and so forth. It plays an important role to recognize the groundwater environmental impact factors of coal chem-ical industry correctly, in monitoring and conserving the groundwater environment in such areas.
