漕河水质污染预测分析

The Water Quality Forecast of the Caohe River in Baoding Town Northwest Suburb

漕河是白洋淀入淀九河之一,其大册营至西庄段位于保定市区西北,因上游大量造纸及城镇污水排放成为污水河,污水部分渗入地下、部分流向白洋淀,成为保定市区最大的水环境问题。通过运用一维稳态水质模型对河流水质进行了分析和预测。模型预测结果及漕河河流自净化分析的结果表明漕河河水流往下游时,有机物的污染趋于减缓,对白洋淀的水质未造成严重影响;总汞及氮可能对沿岸地下水和白洋淀水质有一定影响,应控制水质的恶化程度。

Caohe River is one of the nine river inflooding to Baiyangdian. The Daceying to Xizhuang sect of Caohe River locate in Baoding Town Northwest Suburb and has became a sewage river. The part of sewage filter to ground and the other inflood to Baiyangdian. According to the environment problem of Cache River, a one-dimension model is chosen to predict the water quality and the model parameters are given and determined.. Comparing the actual measuring data with the predictor data, The results of predicting model and Caohe River＇s self-purifying analysis show that when Cache water flows down to the lower reaches, the polluting tendency of organic molecular compound declines,whlch doesn＇t have bad effect on the water quality of Baiyangdian. However,as for Cache River＇s water quality,its deteriorating degree should be controlled.
