| 摘 要： | 由于绍兴污水处理厂排放口是过渡性的,大量未达标的污水排入曹娥江,使得该河段污染负荷很大。为了解绍兴污水排放对曹娥江的水质影响,选用二维水流水质数学模型,采用有限差分格式数值求解方程来计算分析绍兴排污工程达标及未达标排放两种工况分别对曹娥江河口段水质的影响。结果表明,未达标排放时,曹娥江河口段水质污染严重,存在超Ⅴ类水体,若达标排放,水体基本能够满足Ⅲ类水质功能区划要求。就绍兴污水处理厂目前运行状况而言,很难保证本江段水体达到功能区划要求。因此绍兴排污工程污水达标排放对于保护曹娥江河口段的水体是至关重要的因素。

| Abstract: | A large amount of sewage above the standards drain into the Cao'e estuary,making highly pollution in the estuary.To seek the effects of effluent sewage on water quality in the estuary,a 2-D depth-average mathematical model is used to calculate the distribution of water quality on the two cases of effluent sewage up to and above the standards.The results show that the water will be contaminated and the water quality above the fifth class occured if effluent sewage is above the standards, and satisfy to the territorial request of the third class water quality function if effluent sewage is up to the standards.Therefore it is very important to controll Shaoxing effluent sewerage for protecting the water quality in Cao'e estuary. |
