胶州湾入海污染物总量控制研究

Study on the environmental capacity in Jiaozhou Bay

在胶州湾水质数值模拟的基础上,建立了污染物总量控制模型。计算了各个点源的响应系数,分担率及环境容量。结果表明,胶州湾内COD各入海污染源均有余量,不需要削减。胶州湾东北部N、P污染较严重,污染物入海总量已经超过海域的环境容量。研究结果将为胶州湾污水排海、海域水质管理、总量控制规划编制提供科学依据。

Based on the numerical simulated water quality, the total mass control model is established. The response coefficient, share ratio and the environmental capacity are calculated. The results showed that all of the polluted sources have the residual capacity in the Jiaozhou Bay for the COD. Northeast of Jiaozhou Bay is polluted badly for the N and P. The discharge amount of contamination has already exceeded the environmental capacity of the sea area. The results can provide the scientific base for the sewage discharge, the water quality management and the total mass control planning in Jiaozhou Bay.
