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.

Through analyzing and comparing the treatment of fracturing fluid flowback at home and abroad, it can be found that fluid derived organic waste water can be handled by micro electrolysis economically and efficiently. But there are also some shortages of traditional micro electrolysis. So this paper discusses a new micro-electrolysis technology, namely cavitation-impinging stream electrolysis technology which has several advantages in high concentration organic wastewater treatment. The technology can not only solve the problems that the passivation of process and the plugged equipment in the treatment of fracturing fluid flowback fluid by traditional micro electrolysis, but also can better promote the reaction from the reaction kinetics with the help of Coupling application about cavitation and impinging stream technology, so as to realize the purpose of improving the reaction rate and efficiency.
