Background
Since the 20 th century, the consumption of industrial water worldwide has increased by 30 times, and in Asia, the influence of industrial wastewater pollution is the most serious. In China, the reuse rate of industrial water is only 30%, the daily discharge amount of national divided water is nearly 1.64 hundred million tons, and 80% of the water is directly discharged into a water area without treatment, so that the result of 'water pollution' is caused. Wherein 60 percent of coke in the world is produced in China, and the generated coking wastewater is about 2.7 hundred million tons every year. The coking wastewater is high-concentration organic wastewater which is toxic, harmful and difficult to degrade, wherein a large amount of polycyclic aromatic hydrocarbon compounds and heterocyclic organic compounds exist, and meanwhile, cyanide, thiocyanide and sulfide with extremely high toxicity are contained, so that the treatment difficulty is high. The COD removal rate of the traditional biochemical treatment process is only 50 percent.
At present, coking wastewater treatment approaches mainly comprise a dilution biochemical method, a chemical agent treatment method and the like. Because the coking wastewater has high salt content, a large amount of process water is consumed for dilution in order to meet biochemical conditions, and in addition, heterocyclic and polycyclic aromatic compounds such as phenols, naphthalene, cyanogen, pyridine, quinoline and the like in the wastewater are difficult to biodegrade, so that the biochemical dilution method not only wastes water resources, but also has poor treatment effect, and the effluent cannot stably reach the standard. The chemical agent method removes suspended impurities and organic pollutants in the wastewater by adding a large amount of chemical agents, the effluent quality of the method is unstable, the agent cost is high, secondary pollution is caused, and the difficulty of subsequent desalination treatment is increased by adding the agents, so that the method is gradually eliminated or must be applied in cooperation with other process means at present.
