【摘要】 本文从火电厂工业废水回用的角度出发,运用物理化学、微生物学、污水处理等知识,通过理论与实际的有机结合,对工业废水回用于冷却水补充水的方法作了比较全面的论述。作者通过自行设计的实验反应器—微絮凝直接过滤滤柱和生物过滤反应器,探索了优化处理火电厂工业废水的可行性和实用性方案,提出了运用微絮凝亘接过滤—生物滤池的方法,并结合渭河电厂的实例,通过实验证明此工艺在技术上是可行的。基于实验结果,求出Eckenfelder生物滤池模式中常数n和K,为实际的工程设计提供了参考依据。此外,还提出了适合火电厂回用工业废水的工艺流程。

【Abstract】 From the view of reusing industrial wastewaer in Power Plan, amethod that treats industrial watwater to make it reused as complementary water inrecycling cooling watr system is discussed in this paper. Furthermore, the methodcombines theories with pracice, and uses kowedge of physico-chemistry,microbiology, waste water treatment and so on. Feasibility and practicality of thismethod are studied by a series of experiments. So the pyocess of micro-flocculentdirect filtration and,biological filtration was obtained, and proved to be feasible whenapplied to Weihe Power Planet. Based on experimental data, constants n and K usedin Eckenfelder biological filtration model were deduced, which offer reference foractual engineering design. Besides, techeical fiow chart that adaPts to treating andreusing wastewater in power plant is presellted.
