摘　　要：纺织印染企业在退浆、煮炼、染色等生产加工工序产生印染废水,废水经污水处理厂物理、化学或生物方法处理过程中形成的污泥成分复杂,含有大量的染料、助剂和化学药剂,通过健康风险评价模型分析印染污泥堆存场地下水对人体健康和环境产生危害。结果表明:地下水样品中苯胺类(联苯胺)在建设期敏感用地方式下,计算出的致癌风险值超过人体可接受的致癌风险值1×10-6,研究区样品中致癌风险最高值达到1.030×10-3,建设开发期的健康风险水平处于不可接受水平。The health risk assessment model was used to analyze the harm of groundwater on human health and environment. Due to the complex composition of printing and dyeing sludge, containing a large number of dyes, additives and chemical agents, formed in the sewage treatment plant by the physical, chemical or biological methods of treatment of textile printing and dyeing enterprises in desizing, refining, dyeing and other processes of wastewater. The result showed that under the sensitive land mode in the construction period, the calculated carcinogenic risk value of anilines(benzidines) in the groundwater samples exceeded the acceptable human carcinogenic risk value of 1×10-6, the maximum carcinogenic risk in the samples in the study area reached 1.030×10-3, and the health risk level in the construction and development period was at an unacceptable level.
