造纸行业AOX排海浓度预测及渔业影响分析

摘要

在海洋潮流数值模拟的基础上,建立了AOX的输运-扩散模型,并将模型应用于湛江某造纸厂的排海工程中,以预测造纸废水中AOX排海后的浓度分布情况。结合AOX的组分特性,并参照＂渔业水质标准＂（GB11607-89）,选取五氯酚钠作为评价指标,评估AOX排放对于海域水环境质量的影响,分析其排放程度对渔业的影响程度,从而为更好地保护海洋资源提供科学依据。%Through numerical simulation of tidal current,this paper establishes the transport-diffusion model of AOX and applies this model to marine discharge project of a paper mil in Zhanjiang City of Guangdong Province.The AOX concentration of wastewater discharge into the sea was predicted through simulation,Combined with the component characteristic analysis and based on the ＂Fishery Water Quality Standard＂（GB11607-89）,the Pentachlorophenol Sodium（PCP-Na） was selected as the index to evaluate the influence of AOX emission on the marine water environmental quality and to further analyze its influence on fishery industry,which can provide scientific basis for better protection of marine resources.
