摘要
以城中湖西园排污口的水质监测数据和相关水文参数为基础,运用湖泊推流衰减模式推算城中湖的降解系数K,KCOD、KTP和KTN分别为0.0011d-1、0.00151d-1和0.0010d-1。选择质量平衡方程作为水环境容量的计算模型,分别以COD、TP和TN为控制因子,计算了城中湖的水环境容量。根据排入城中湖的污染源调查和水环境容量计算结果,得到城中湖水环境容量余量。针对城中湖现状,提出了防止城中湖水体富营养化的措施和建议。
Based on monitoring data of a wastewater outfall of Chengzhong Lake and related hydrological parameters, lake plug flow attenuation mode was formulated to estimate the degradation coefficient of the Lake, with degradation coefficient of COD, TP and TN as 0.0011d^-1, 0.00151d^-1 and 0.0010d^-1 Mass-balance equation was selected as capacity mode for COD, TP and TN in water environment. According to pollution source of discharge into the Lake and its water environment capacity, the remaining environment capacity was obtained. Suggestions and measures to prevent eutrophication were also proposed.
