Study on preparation of a novel needle coke heterogeneous electro-Fenton cathode for coking wastewater treatment

Efficient degradation of COD from coking wastewater by corncob biochar-modified particles using a three-dimensional electrode reactor

“…These changes in fluorescence peak intensity were caused by changes in the composition and content of refractory organic compounds in the coking wastewater, and the fluorescence peaks of B and C almost disappeared while some aromatic protein substances remained after 120 min of the reaction. 45 These results showed that the ˙OH radicals generated by the catalytic oxidation of Fe–Mn/BC particle electrodes could effectively degrade most organic pollutants in the coking wastewater.…”

Technical and financial feasibility of a chemicals recovery and energy and water production from a dairy wastewater treatment plant

“…Accordingly, the increasing development of wastewater treatment and resource recycling technologies is necessary to reduce the environmental impacts of wastewater discharge 7 – 9 . Among the various industries, the dairy factory is one of the industries that produces huge wastewater; such that to produce one liter of milk, around 2.5 L of water is consumed and the same amount of wastewater is produced 10 , 11 . Wastewater treatment and recycling in such industries can simultaneously reduce freshwater consumption and the environmental impacts of wastewater discharge into the environment 12 , 13 .…”
