  • 摘要: 为评估河流治污措施对河道水质改善的效果,用MIKE11模型对伏牛溪河道主要污染物氨氮和CODMn进行了数值模拟。结果表明:河道沿程点源全部截污后,可降低43%的氨氮和65%的CODMn,水质基本达到Ⅴ类水标准;补充20 000 m3/d污水厂尾水(仅深度处理其中6 000 m3/d),河道氨氮浓度将升高12%、CODMn浓度可降低17%,水质不能满足Ⅴ类水标准;补充20 000 m3/d全部深度处理的污水厂尾水,可以降低39%的氨氮和42%的CODMn,水质基本可达到Ⅴ类水标准;采取组合措施后,氨氮可降低12%~37%,CODMn可降低7%~30%。组合措施优于单一措施。
    Abstract: In order to assess the effect of river pollution control measures on improving the water quality, ammonia nitrogen and CODMn of FuNiu River was simulated by using the MIKE11 model.The results show that ammonia nitrogen and CODMn can be reduced 43% and 65%, respectively after cutting off point source pollution along the river, basically reached V surface water quality.After only supplying 6 000 m3/d tail water by advanced treatment, ammonia nitrogen can be increased 12% and CODMn can be reduced 17%.Ammonia nitrogen and CODMn can be reduced 39% and 42%, respectively after supplying 20 000 m3/d tail water by advanced treatment, basically reached V surface water quality too.By taking combined measures, ammonia nitrogen and CODMn can be reduced 12%~37% and 7%~30%, respectively .This suggests that combined measures are better than a single measure.
