摘要： 煤化工企业在生产的过程中会产生大量高含盐量的工业废水。搜集了多种典型的工业废水进行水样分析，得到废水中普遍存在的重金属及其一般含量，然后将这些重金属添加到模拟废水中进行实验研究。对重金属的去除技术进行了条件优化，有望解决现有技术中存在的沉淀剂消耗量大、重金属去除效率低等问题，为今后实现高含盐废水中水、气、盐的资源化利用提供参考。

Abstract: A great deal of high-salinity industrial wastewater is always come into being during the production process in coal chemical industry enterprises. Various kinds of typical industrial wastewater samples have been collected and analyzed. As a result,the widespread heavy metals and their generic contents were found. Then,experimental research on these heavy metals have been implemented by adding them to simulated wastewater,and optimizing the conditions for the heavy metals removing technology. The problems existed in present technologies,such as high consumption of precipitants,low removing rate of heavy metals,etc. will hopefully be solved,providing reference for achieving the water,gas,and salt resource utilization of high-salinity wastewater.

Key words: high-salinity wastewater, heavy metals, precipitation
