英文摘要： Taking heavily polluted rivers in the north as subject, the research studies on features of sediment pollution of heavily polluted rivers and sediment in situ remediation technology which includes sediment oxidation, sediment stabilization and bioremediation of indigenous activated sludge of sediment. Through experimental simulation, the research studies on the characteristics of sediment pollution of heavily polluted rivers in the north as well as the causes and regularities of heavily polluted rivers, providing a theoretical foundation for the realignment of heavily polluted rivers. Aiming at the characteristics of heavily polluted rivers under low temperature, a set of technologies suitable for the bioremediation of indigenous activated sludge of sediment in the north are designed and research on remediation effect and mechanism is done to provide theoretical and technical reference for the general realignment of heavily polluted rivers. Combining with the characteristics of polluted rivers, the research focuses on the design and development of technique and equipment and their application in engineering fields. It also studies on the remediation effects and optimization of relative technique, which works as engineering experience for the realignment of heavily polluted rivers.
