底泥内源污染对水体黑臭化影响及治理的研究

Study on the Effect of Sediment Endogenous Pollution on Black-odorous Water and Its Treatment

底泥内源污染引起的黑臭变化研究涉及水体、底泥、微生物、植物等多种生态对象,由再生水本身因成分复杂致使对该类水体氮磷释放及黑臭化的研究更加复杂。研究结果表明,底泥内源污染对水体黑臭化具有一定的影响,其中温度、溶解氧、pH值、水动力等是重要的影响因素。在河道治理中,单一的治理技术因为自身的限制因素较多,不能很好地治理河道污染,因而将生态、化学和物理等方法有效地结合起来,形成更系统、更全面的河流污染治理技术已成为当今主要研究方向。

The study of sediment endogenous pollution on black-odorous water involved water body,sediment,microorganisms,plants and other ecological objects.Due to the complex composition of reclaimed water,the study on the release of nitrogen and phosphorus or black-odor of reclaimed water was more complicated.The results showed that the endogenous pollution of sediment had a certain influence on black-odorous water,in which the temperature,dissolved oxygen,pH and hydrodynamics were the important factors.Due to its own limitations,single treatment technology could not repair river in river channel regulating engineering.Therefore,ecological,chemical and physical methods will be effectively coupled to form a more systematic and comprehensive technology to curb river pollution.
