A bioartificial liver (BAL) based on human induced pluripotent stem cells (iPSCs)-derived hepatocyte-like cells (HLCs) and a multilayer porous bioreactor is provided. The plasma separation/retransfusion loop part includes a blood input pipe, an exhaust pipe spring clamp, a blood input peristaltic pump, a heparin pump, a plasma separation column, a first pressure monitor, and a heater. The cell reactor/plasma component exchange double-loop part includes a plasma input peristaltic pump, and a semipermeable membrane exchange column, a plasma exchange peristaltic pump, a red blood cell (RBC) pool, a membrane lung, a multilayer porous bioreactor, a second pressure monitor, and a third pressure monitor arranged in a 37&#xb0; C. dedicated incubator. An outlet of the third pressure monitor and a blood cell outlet are connected to an inlet of the first pressure monitor, and then connected to the heater and a blood output pipe in sequence.

A method for treatment of coke wastewater, including (1) introducing wastewater into a regulating reservoir into which an acid liquor is added until the pH value of the wastewater ranges between about 5.5 and about 6.5; (2) introducing the wastewater into a three-dimensional electrode treatment device for electrolysis treatment; and (3) introducing the wastewater into a coagulation reaction tank into which an alkali liquor is added until the pH value of the wastewater ranges between 8 and 10, and as a coagulant polysilicate ferric magnesium is added into the wastewater for a hybrid reaction of between 5 and 15 mins; allowing the wastewater to flow into a sedimentation basin for plain sedimentation of between 4 and 6 hrs; and extracting a supernatant liquor to yield a processed effluent.

A new method that integrates electrochemical oxidation and flocculation processes for removing ammonia nitrogen in coking wastewater is disclosed in this invention. It comprises steps as follow: first, adjusting the PH of coking wastewater and adding Feinto the wastewater; then leading the wastewater containing Fethrough such 5 areas as pulsed high-voltage discharge oxidation area, pulsed high-frequency DC electrolytic oxidation area, microbubble oxidation area, flocculation area and precipitation area in succession. High-voltage pulse and high-frequency pulse are two different mechanisms for achieving strong oxidation. With help of both solid and liquid catalysts, these two oxidations can work synergistically. The recalcitrant organic chemicals are effectively destroyed and satisfactorily removed out of wastewater. The high-concentration coking waster pretreated with this method will meet Chinese highest discharge standard as long as the routine biochemical treatment is applied thereafter. The total investment on equipments and operation expenditure of the whole system is economically modest, which, together with its highly efficient treatment performance, ensures its extensive application in the field of wastewater treatment.
