TLDR
The GC/MS analysis demonstrated that some refractory compounds were decomposed at the acidogenic stage and resulted in the production of some intermediates, which were more readily degraded in the subsequent aerobic stage and hence, the A(1)-A(2)-O system had better effluent quality than the A-O system in terms of effluent composition.About:

Constructed wetlands for treatment of industrial wastewaters: A review
TL;DR: In this article, constructed wetlands have been used for wastewater treatment for more than fifty years and most applications have been designed to treat municipal or domestic wastewater but at present, constructed wetlands are successfully applied to many types of wastewater.

Inhibitory effects of toxic compounds on nitrification process for cokes wastewater treatment.
TL;DR: In conclusion, cokes wastewater is one of the most toxic industrial effluents since it contains high concentrations of toxic compounds such as phenols, cyanides and thiocyanate, and activated carbon was added to reduce inhibitory effects of phenol and free cyanide and Phenol and p-cresol significantly inhibited nitrification above 200 mg/L and 100mg/L, respectively.

Removal of phenols, thiocyanate and ammonium from coal gasification wastewater using moving bed biofilm reactor
TL;DR: A laboratory-scale moving bed biofilm reactor (MBBR) with a volume of 4 L was used to study the biodegradation of coal gasification wastewater and maximum removal efficiencies of 81%, 89%, 94% and 93% were obtained for COD, phenols, SCN(-) and NH(4)(+)-N, respectively.
Journal ArticleDOI
Simultaneous removal of phenol, ammonium and thiocyanate from coke wastewater by aerobic biodegradation.
TL;DR: A maximum nitrification efficiency of 71% was achieved when bicarbonate was added, the removals of COD and phenols being almost similar to those obtained in the absence of nitrification, as the alkalinity of the wastewater was very low.
Journal ArticleDOI
Treatment of coke wastewater in a sequential batch reactor (SBR) at pilot plant scale.
TL;DR: The biological treatment in the SBR led to removal efficiencies of 85% COD, 98% thiocyanate and 99% phenols for HRT of 115 h and final concentrations in the effluent of 1.8 mg phenols/L, 5.4 mg SCN/L and 78 mg N-NH(4)(+)/L were obtained.

The degradation of dyestuffs: Part III - Investigations of their ultimate degradability
D. Brown,B. Hamburger +1 more
TL;DR: In this paper, the identification of amine metabolites arising from the anaerobic biodegradation of dyestuffs, and examining their possible an-aerobic and aerobic biodegradability using both specific and nonspecific analytical methods, is presented.

Anoxic degradation of nitrogenous heterocyclic compounds by acclimated activated sludge
TL;DR: In this article, a batch of experiments were conducted to investigate anoxic biodegradation of five refractory nitrogeneous heterocyclic compounds, i.e., pyridine, indole, quinoline, isoquinoline, 2-methyl quinol, in coke plant wastewater.
