==Phenolic byproducts==

Wastewater from coking is highly toxic and carcinogenic. It contains phenolic, aromatic, heterocyclic, and polycyclic organics, and inorganics including cyanides, sulfides, ammonium and ammonia.<ref>{{Cite web|title = Cutting-Edge Solutions For Coking Wastewater Reuse To Meet The Standard Of Circulation Cooling Systems|url = http://www.wateronline.com/doc/cutting-edge-solutions-for-coking-wastewater-reuse-to-meet-the-standard-of-circulation-cooling-systems-0001|website = www.wateronline.com|access-date = 16 January 2016|url-status = live|archive-url = https://web.archive.org/web/20160815171844/http://www.wateronline.com/doc/cutting-edge-solutions-for-coking-wastewater-reuse-to-meet-the-standard-of-circulation-cooling-systems-0001|archive-date = 15 August 2016}}</ref> Various methods for its treatment have been studied in recent years.<ref>{{Cite journal|title = Coking wastewater treatment for industrial reuse purpose: Combining biological processes with ultrafiltration, nanofiltration and reverse osmosis|journal = Journal of Environmental Sciences|date = 1 August 2013|pages = 1565–74|volume = 25|issue = 8|doi = 10.1016/S1001-0742(12)60212-5|first1 = Xuewen|last1 = Jin|first2 = Enchao|last2 = Li|first3 = Shuguang|last3 = Lu|first4 = Zhaofu|last4 = Qiu|first5 = Qian|last5 = Sui|pmid = 24520694|doi-access = free}}</ref><ref>{{Cite journal|title = Advanced treatment of coking wastewater by conventional and modified fenton processes|journal = Environmental Progress & Sustainable Energy|date = 1 July 2013|issn = 1944-7450|pages = 176–80|volume = 32|issue = 2|doi = 10.1002/ep.10626|language = en|first1 = Dünyamin|last1 = Güçlü|first2 = Nazan|last2 = Şirin|first3 = Serkan|last3 = Şahinkaya|first4 = Mehmet Faik|last4 = Sevimli| bibcode=2013EPSE...32..176G | s2cid=98288378 }}</ref><ref>{{Cite journal|title = Study on the treatment of simulated coking wastewater by O3 and O3/Fenton processes in a rotating packed bed|issue = 113|pages = 93386–93393|journal = RSC Advances|volume = 5|doi = 10.1039/C5RA14198B|language = en|first1 = Qing|last1 = Wei|first2 = Shufeng|last2 = Qiao|first3 = Baochang|last3 = Sun|first4 = Haikui|last4 = Zou|first5 = Jianfeng|last5 = Chen|first6 = Lei|last6 = Shao|date = 29 October 2015|bibcode = 2015RSCAd...593386W}}</ref> The white rot fungus ''[[Phanerochaete chrysosporium]]'' can remove up to 80% of [[phenols]] from [[coking]] waste water.<ref>{{Cite journal |last1= Lu |first1= Y |last2= Yan |first2= L |last3= Wang |first3= Y |last4= Zhou |first4= S |last5= Fu |first5= J |last6= Zhang |first6= J |title= Biodegradation of phenolic compounds from coking wastewater by immobilized white rot fungus Phanerochaete chrysosporium |journal= Journal of Hazardous Materials |volume= 165 |year= 2009 |issue= 1–3 |pages= 1091–97 | pmid = 19062164 |doi= 10.1016/j.jhazmat.2008.10.091}}</ref>
