摘要
根据污染源现状调查结果与污染源预测方法,预测了水平年东圳水库流域污染负荷.结果表明,流域污染负荷主要来自农业面源、生活污水和生活垃圾,其中农业面源是流域最大污染源,而农业面源中主要是果园径流污染.在构建东圳水库水域二维水流水质数学模型的基础上,基于流域污染负荷预测结果,模拟分析库区水环境变化趋势,结果为库区总氮和总磷将难以满足Ⅲ类水质标准要求.根据污染源调查及水质影响预测结果,建议加强对东圳水库水环境保护,重点开展果园面源污染控制、生活污水收集处理及生活垃圾收集转运处置等项目.
Abstract
Based on the status of pollution load and its prediction methods,the pollution load of level year of Dongzhen Reservoir basin was predicted.The results showed that the pollution mainly came from agricultural non-point source pollution,domestic sewage and domestic garbage,of which orchard non-point pollution was the major source.Based on the prediction results of pollution load Dongzhen Reservoir basin,a two-dimensional water quality mathematical model was constructed for the purpose of evaluating the change trend of water quality.The results showed that total nitrogen and total phosphorus can't meet Grade Ⅲ of Surface Water Quality Standard.Consequently,it was suggested to strengthen environmental protection of Dongzhen Reservoir,focusing on orchard non-point source pollution control,domestic sewage and garbage disposal.
