摘要
慈溪市位于浙江北部经济发达的平原河网地区,2006年前,大量工业废水和多数未经处理的生活污水经市区和各镇区内河排入河网水系,最终排入杭州湾,对内河和海域污染较重,其市域污水治理工程一方面扩大地区管网和污水处理能力,另一方面扩大供水能力进行治理。采用一维水环境数值模型,在验证基础上模拟计算了工程进行前后内河水质CODMn的变化,为工程环境影响评价提供可靠的数值。
Cixi City is located on the plain river network region of economically prosperous Northern Zhejiang. Before 2006, large quantities of industrial waste water and a majority of untreated urban and township sewage were discharged into the Hangzhou Bay through the river network, causing heavy pollution in rivers and sea. The sewage treatment project of the city has been undertaken by expanding regional pipe network and sewage treatment capacity, as well as by enlarging water supply capacity. With a 1-D water environment numerical model and verification, this study simulated the change in CODMn of water quality before and after the implementation of such project, providing reliable results for environmental impact evaluation.
