中文摘要：
针对焦化废水处理工程设计过程中极少涉及基于氰化物浓度变化与考察分析的实际问题,通过对已经运行的广东韶钢集团焦化废水处理工程统计数据的辨析,提出实现总氰化物高效去除的技术与运行强化方法。分析数据发现,在降解的过程中,氰化物滞后于酚类代表的有机物,络合氰的降解比游离氰慢,生物处理过程中由水力停留时间控制的碳源利用与金属离子的存在影响氰化物的降解,而A/O1/H/O2工艺在有效分配除碳过程与脱氮过程中实现了氰化物的高效降解。进一步工程实践证明,焦化废水处理全部指标达标的高效性可以通过充分考虑复杂组分降解动力学的协同与优化操作条件加以实现。
英文摘要：
Few studies have been devoted to the real-time analysis of the variation in cyanide concentration in a coking wastewater treatment plant,although this is important for the design of such a plant.This work presented a method to allow high-efficiency removal of cyanide,based on the analysis of the data collected from a real A/O1/H/O2 coking wastewater treatment plant（Shaogang,Guangdong）.The results showed that the biodegradation rate of cyanide was much slower than that of phenols present in the biological system,and the degradation rate of metal-complexed cyanide was much slower than that associated with uncomplexed cyanide.The effective removal of carbon and nitrogen in the A/O1/H/O2 biological system was responsible for achieving high-efficiency biodegradation of cyanide.In addition,this work demonstrated that the high-efficiency treatment of coking wastewater could be realized by taking into account the synergetic effect of biodegradation kinetics for different components and the optimization of operating conditions.
