“…On the other hand, excessive ammonium and sulfate can be generated during biological treatment of coking wastewater (Joshi et al, 2016;Staib and Lant, 2007;Vazquez et al, 2006a), suggesting possible biodegradation of nitrogen-and sulfur-containing organic and inorganic compounds. Based on the low chemical oxygen demand to total organic carbon (COD/TOC) ratio (Lim et al, 2003), refractory organic compounds including nitrogen-and sulfur-containing compounds (Huang et al, 2016;Zhang et al, 2013a), may represent a substantial fraction as only nitrogenous compounds constitute approximately 20e40% of the organic component in coking wastewater (Li et al, 2003;Meng et al, 2016). Indeed, nitrogen and sulfur-containing compounds are of great environmental importance due to their high toxicity and persistence (Dehua et al, 2016;Jensen et al, 2003) and hence might be critical for the treatment of coking wastewater.…”

Although coking wastewater is generally considered to contain high concentration of nitrogen- and sulfur-containing pollutants, the biotransformation processes of these compounds have not been well understood. Herein, a high throughput functional gene array (GeoChip 5.0) in combination with Illumina MiSeq sequencing of the 16S rRNA gene were used to identify microbial functional traits and their role in biotransformation of nitrogen- and sulfur-containing compounds in a bench-scale aerobic coking wastewater treatment system operated for 488 days. Biotransformation of nitrogen and sulfur-containing pollutants deteriorated when pH of the bioreactor was increased to >8.0, and the microbial community functional structure was significantly associated with pH (Mantels test, P < 0.05). The release of ammonia nitrogen and sulfate was correlated with both the taxonomic and functional microbial community structure (P < 0.05). Considering the abundance and correlation with the release of ammonia nitrogen and sulfate, aromatic dioxygenases (e.g. xylXY, nagG), nitrilases (e.g. nhh, nitrilase), dibenzothiophene oxidase (DbtAc), and thiocyanate hydrolase (scnABC) were important functional genes for biotransformation of nitrogen- and sulfur-containing pollutants. Functional characterization of taxa and network analysis suggested that Burkholderiales, Actinomycetales, Rhizobiales, Pseudomonadales, and Hydrogenophiliales (Thiobacillus) were key functional taxa. Variance partitioning analysis showed that pH and influent ammonia nitrogen jointly explained 25.9% and 35.5% of variation in organic pollutant degrading genes and microbial community structure, respectively. This study revealed a linkage between microbial community functional structure and the likely biotransformation of nitrogen- and sulfur-containing pollutants, along with a suitable range of pH (7.0-7.5) for stability of the biological system treating coking wastewater.

The current study is designed for the eradication of phenol and cyanide from a simulated binary mixture involving acetic acid modified spent tea activated carbon (STAC‐C), isolated bacterial strain Alcaligenes faecalis JF339228, and immobilized A. faecalis JF339228 onto spent tea biochar by an amalgamated approach of sorption coupled with biodegradation. Characterisation of the biosorbent was ascertained by field emission scanning electron microscopy, thermogravimetric analysis, and Fourier transform infrared spectroscopy. The viability for eco‐benign expulsion of the pernicious pollutants, and the resultant compounds after treatment was examined by fluorescence and UV‐visible spectrophotometry with comprehensive elucidation of the interactions with DNA. Gas chromatography–mass spectrometry (GC‐MS) anatomization was conducted for the evaluation of degraded derivatives post‐treatment. The chemical and structural analysis of the degraded compounds and its impact upon disposal on the basis of degree of toxicity and reactivity were evaluated using TOXTREE software. Batch studies were implemented for the evaluation of process parameters like pH, reaction time, biosorbent or inoculum dosage, initial concentration, and temperature. Mono and binary component isotherm modelling was executed. Immobilised cells and free cells could accomplish better removal efficacy of 94.71% and 92.25% for cyanide, respectively, whereas adsorption using STAC‐C was responsible for maximum removal of phenol up to 86.29%.

“…To tackle this problem the combination of anaerobic-anoxic-oxic processes along with other hybrid biological systems have now proven to be a better biological treatment method for coking wastewater (Zhou et al 2014;Liu et al 2017a). Placing anaerobic process in the first step improves biodegradability and helps in the removal of some inhibitory compounds, ensuring better performance in the subsequent stages (Wang et al 2011;Zhou et al 2013;Huang et al 2016). In one study, the use of a hybrid anoxic reactor with completely mixed aeration tanks utilizing granular biomass under fluidized conditions resulted in the removal of 88% of ammoniacal nitrogen, 90% COD, and almost 99 and 100% for cyanide and phenol (Maneesh et al 2018).…”

“…The diversity of microbial population and species richness is dependent on different biological treatment processes, operation modes, temperature, and flow rate (Zhu et al 2015;Liu et al 2018c). Microbial community distribution using gene sequencing analysis has helped in understanding the correlation of species with the degradation of biorefractory compounds (Huang et al 2016). For instance, Pseudomonas putida and Pseudomonas stutzeri have been identified as potential bacterial strain for the effective degradation of phenol and cyanide .…”

Coking wastewater poses a serious threat to the environment due to the presence of a wide spectrum of refractory substances such as phenolic compounds, polycyclic aromatic hydrocarbons and heterocyclic nitrogenous compounds. These toxic substances are difficult to treat using conventional treatment methods alone. In recent years much attention has been given to the effective treatment of coking wastewater. Thus, this review seeks to provide a brief overview of recent developments that have taken place in the treatment of coking wastewater. In addition, this article addresses the complexity and the problems associated with treatment followed by a discussion on biological methods with special focus on bioaugmentation. As coking wastewater is refractory in nature, some of the studies have been related to improving the biodegradability of wastewater. The final section focuses on the integrated treatment methods that have emerged as the best solution for tackling the highly unmanageable coking wastewater. Attention has also been given to emerging microwave technology which has tremendous potential for treatment of coking wastewater.
