Abstract

Abstract:

Coal chemical wastewater has the characteristics of complex composition，high pollutant content，great harm，and high treatment difficulty. It has become an urgent demand for the development of China’s coal chemical industry to seek efficient，stable，and low-cost coal chemical wastewater treatment process. Taking the wastewater from the regulating tank of a coal chemical plant in Xinjiang as the treatment object，the study on improving the treatment efficiency of coal chemical wastewater was carried out by means of Anaerobic/Oxic process（A/O） and Moving-Bed Biofilm Reactor （MBBR） coupled water treatment technology. In the study，the treatment effects of two different MBBR fillers on the pollutants in the wastewater were mainly investigated. The pilot experiment results showed that the two different fillers had similar effects in COD removal rate. The filler Ⅱ showed better performance in nitrification and denitrification capacity. The TP removal effect of filler Ⅰ was better than that of filler Ⅱ. Moreover，the A/O-MBBR coupling process operated stably，and had certain anti COD impact load capacity，which made it had practical application potential.

摘要：

煤化工废水成分复杂、污染物含量高、危害大、处理难度高，寻求高效稳定、成本低廉的煤化工废水处理工艺已经成为我国煤化工产业发展的迫切需求。选取新疆某煤化工厂调节池废水为处理对象，通过厌氧好氧工艺（A/O）和移动床式生物膜反应器（MBBR）相耦合的水处理技术进行提升煤化工废水处理效能的研究，研究过程中重点考察了2种不同的MBBR填料对废水中污染物的处理效果。中试实验结果表明：2种不同的填料在COD去除率方面效果相当；采用填料Ⅱ的耦合工艺的硝化与反硝化能力更强，出水NH₃-N与TN均优于采用填料Ⅰ工艺的出水指标；在TP去除方面，采用填料Ⅰ对系统的优化效果优于采用填料Ⅱ的效果；A/O-MBBR耦合工艺整体运行稳定，有一定的抗COD冲击负荷能力，具有实际应用潜力。
