Patent number: 9573825Abstract: The present invention discloses a method for advanced treatment of bio-treated coking wastewater. It employs polymeric ferric sulfate (PFS) and polyacrylamide (PAM) as the flocculant for the pre-treatment of bio-treated effluent. After the process of precipitation and filtration, the effluent is guided through an adsorption column filled with environmentally-friendly nano-composites whereby the advanced treatment of the bio-treated coking wastewater is achieved. When the absorption process reaches the breakthrough point, the adsorption operation will be stopped and sodium hydroxide solution is used as the desorption reagent for regenerating the nano-composites. The high-concentrated component of the desorption liquid is sent out for incineration or production of coal water slurry, meanwhile the low-concentrated component of the desorption liquid is used to prepare sodium hydroxide solution for the adsorption process of the next batch.Type: GrantFiled: October 23, 2012Date of Patent: February 21, 2017Assignee: NANJING UNIVERSITYInventors: Bingcai Pan, Wenlan Yang, Lu Lv, Weiming Zhang, Yingnan Jiang
