枣庄东湖秋冬季水质研究

Study on Water Quality in Autumn-Winter Period of Zaozhuang East Lake

枣庄东湖位于枣庄市东湖公园,其水质的好坏影响着东湖周边市民的生活质量.在秋冬季节选取10个采样点对枣庄东湖水体进行定点采样,检测水体中的温度、氨氮浓度、硝酸盐氮浓度、亚硝酸盐氮浓度和磷酸盐浓度.结果表明枣庄东湖氨氮浓度均值为0.12mg/L属于Ⅰ类水质,硝酸盐的均值浓度为76.4mg/L污染程度较严重,亚硝酸盐浓度均值为0.005mg/L污染程度较轻,磷酸盐均值浓度为0.1mg/L污染程度较高.

Located in the East Lake Park of Zaozhuang City,Zaozhuang East Lake affects people’s quality of life with its water quality.Ten sampling points were selected to sample Zaozhuang East Lake water during the autumn-winter period.The water temperature,ammonia nitrogen concentration,nitrate nitrogen concentration,nitrite nitrogen concentration and phosphate concentration were measured.The results show that the average concentration of ammonia nitrogen in Zaozhuang East Lake is 0.12mg/l,indicating that the lake is of class I water quality;the average concentration of nitrate is 76.4mg/l,showing the lake is of serious pollution degree;the average concentration of nitrite is 0.005mg/l,making it clear that the the lake is of light pollution,but the average concentration of phosphate is 0.1mg/l,showing a high pollution level.
