摘　　要：以云浮市铸造工厂区域水环境为调查对象,旨在评估新建铸造生态工厂的排污对环境的潜在影响。基于地理信息系统(GIS)分析、水质监测与化验、废水排放模型建立与预测的方法,选取COD_(cr)、NH_(3)-N和氟化物作为监测指标,并建立预测模型来分析废水排放对水环境的潜在影响。结果表明:铸造生态工厂排放口下游1 m处作为污染源排放量核算断面的数据分别为:COD_(cr)最大浓度为12.11952 mg/L、氨氮最大浓度为0.75045 mg/L、氟化物最大浓度为0.24681 mg/L,各项指标均满足要求。研究有助于企业评估废水排放对区域水环境的潜在影响,可准确评估新建企业对水环境的影响,为保护水环境、管理风险、确保企业合规运营提供必要支持和决策依据。Taking the water environment of the casting factory area in Yunfu City as the survey object,this study aims to evaluate the potential impact of pollution discharge from newly built ecological casting factories on the environment.Based on the methods of geographic information system(GIS)analysis,water quality monitoring and analysis,and establishment and prediction of wastewater discharge models,COD_(cr)(chemical oxygen demand),NH_(3)-N(ammonia nitrogen),and fluoride are selected as monitoring indicators,and a prediction model is established to analyze the potential impact of wastewater discharge on the water environment.The results show that the data of the pollution source emission accounting section located 1m downstream of the planned new ecological foundry factory discharge outlet are:the maximum concentration of COD_(cr) is 12.11952mg/L;the maximum concentration of ammonia nitrogen is 0.75045mg/L,and the maximum concentration of fluoride is 0.24681mg/L,all of which meet the requirements.This study helps enterprises evaluate the potential impact of wastewater discharge on regional water environment and accurately assess the impact of new enterprises on water environment,which provides necessary support and decision-making basis for protecting water environment,managing risks,and ensuring compliant operation of enterprises.
