A continuous flow double chamber microbial fuel cell (MFC) for wastewater treatment was constructed. Anaerobic activated sludge was used as bacterial source and simulated organic wastewater was used as substrate. Effluent of anode chamber was used directly as influent of the cathode chamber. The aerobic microorganisms could degrade organic matters further. The electricity production and organic wastewater treatment of the MFC were studied. The results show that the wastewater chemical oxygen demand (COD) of the total removal rate was 74.1%~77.45%, the anode chamber in which the removal rate of COD is 32.2%~35.3%, and COD removal efficiency of aerobic biological treatment in the cathode chamber was 60.2%~66.7%. The continuous flow system could improve the removal rate further. The maximum current density of MFC was 1.56 mAm-2, the maximum output power was 24.336 mWm-2.

This chemical synthesis-based pharmaceutical wastewater is treated by the process of hybrid hydrolysis acidification technique (HHAT) with anaerobic-low DO condition and the hybrid aerobic bio-technology consisted of alternate-flow biological reactor (ABR) and two-way-flow biological aerated filter (TBAF). The micro aerobic technology was employed in the HHAT and showed its advantages in refractory organic wastewater treatment. The largest plant in pharmaceutical wastewater treatment at home was built. The practice shows that the organics can be greatly removed and the effluent can reach the First Grade Discharge Standard which can be reclaimed with advanced treatment. The performance indicates that the combined bio-technologies are stable in pharmaceutical wastewater treatment.

Abstract. UASB, bio-contact oxidation, coagulation and floating process was adopted in treatment of juice wastewater. Operation results show that when the main pollutants of COD, BOD and SS in the influent were 6033 mg•L-1, 2512 mg•L-1 and 2200mg•L-1, the effluent could reach 63 mg•L-1, 25 mg•L-1 and 29 mg•L-1, respectively, with the removal rate of 99.0 %, 99.0 %, 98.7 %. The effluent reached the I-class criteria specified in Integrated Wastewater Discharge Standard (GB8978-1996) (COD < 60 mg•L-1, BOD < 20 mg•L-1, SS < 20 mg•L-1). The process provides a practical reference for the similar high concentration organic wastewater treatment processing.
