摘 要:三江堰湿地公园春季的水质:p H为7.14,COD值为23.25 mg/L,总氮含量为9.45 mg/L,总磷含量为0.62 mg/L;夏季的水质:p H为7.97,COD值为27.72 mg/L,总氮含量为9.79 mg/L,总磷含量为0.81 mg/L。春夏两季的水质存在一定的差异性,主要是因为夏季高温,蒸发量大,造成夏季的p H、COD含量、总磷含量和总氮含量都比春季的高。但不论春夏哪季,其水质中的总氮和总磷均超《地表水环境质量标准》中5类水的标准。故因在三江堰湿地公园的进水口处修建处理设施,降低污染指标。The water quality of Sanjiangyan wetland park in spring, pH was 7.14, COD value was 23.25 mg/L, total nitrogen content was 9.45 mg/L, total phosphorus content was 0.62 mg/L; the water quality of Sanjiangyan wetland park in summer, pH was 7.97, COD value was 27.72 mg/L, total nitrogen content was 9.79 mg/L, total phosphorus content was 0.81 mg/L. Spring and summer water quality there are some certain difference, mainly because of the high temperature in summer, evaporation is large, so the contents of pH, COD, total phosphorus and total nitrogen in summer were higher than those in spring. But regardless of spring and summer, total nitrogen and total phosphorus are more than five type of water standards. So we must construction of treatment facilities in the entrance of the Sanjiangyan wetland park, reduce pollution.
