典型煤化工废水中特征污染物的迁移转化及废水毒性削减研究

, 2017
煤化工产业是推动我国经济建设和发展的重要产业，但组成复杂、污染物浓度高、毒性大的煤化工废水的产生，不仅制约了煤化工行业的发展，也对环境造成了危害。本文通过选取适当的分析方法，较为全面地研究了煤化工废水中污染物的组成、去除特点以及废水的毒性削减特点，得到主要结论如下：（1）对三种煤化工工艺废水以及其在废水处理过程中的变化特征研究表明，煤化工工艺以及煤种对废水有机污染物的产生具有重要影响：焦化废水、碎煤加压气化废水和水煤浆气化废水污染情况各异，但主要有机污染物均为酚类、多环芳烃以及含氮化合物 ...

保安湖沉积物和间隙水中氮和磷的含量及其分布

, 2000
保安湖沉积物中氮(N)的含量平均为5.20mg/g，平面分布以桥墩湖区含量最高。沉积物中磷(P)的含量平均为0.75mg/g，平面分布以扁担塘湖区含量最高。沉积物间隙水中总氮的平均含量为3.63mg/L，无机氮中以氨氮的含量最高，占总氮的57.2%；间隙水中总磷的含量平均为0.098mg/L，磷酸盐占总磷的50.0%。间隙水中氮和磷含量的平面分布差异不明显。间隙水中氮和磷的含量比湖水中含量高，但除氨氮外，一般不超过5倍 ...
