摘要
本文运用水体中各类物质平衡原理,通过适当的测量和模拟,分别讨论了水生植物作用显著和不显著两种状态下,河流水污染物环境生物-地球化学过程定量分析的技术方法。分别给出定量分析总磷、有机物(CODcr计)和氮素的沉积物释放、沉降再悬浮、水体生化降解、水生植物吸收吸附及氮素的氨化硝化反硝化等环境生物-地球化学过程物质变化的绝对量和平均速率的技术方法。
Using various substances in water balance principle,the paper discusses the quantitatively analyseing techniques of river water pollutants'environmental biological-geochemical process,under the two states that aquatic plants affect remarkablely and unremarkablely,through appropriate measurement and simulation.This paper respectively gives the technique that quantitatively analyses the matter change absolute amount and average rate of total phosphor,organic matter(COD_Cr),and nitrogen in environment biological-geochemical process where the sediment releases pollutants,pollutants settle and re-suspend,river water resolves pollutants by biochemistry,aquatic plant absorbs and adsorbs pollutants,and nitrogen ammoniates,nitrifies,and denitrifies.
