The relevant process of the wastewater treatment and a combined process of UASB+SBR disposal were proposed in this article. The main characteristics of the wastewater were large quantities of organic materials, high concentrations of organic pollutions and high COD. UASB ( Up-flow Anaerobic Sludge Bed/Blanket ) technology was a kind of method of sewage treatment invented by Lettinga,a Holland professor in 1977.It was a very popular process in organic wastewater Treatment. With continuously improving and developing since 70s, it showed many advantages in the treatment of high concentration organic biological wastewater compared with other organic biological technology, such as lower costing, higher loading, smaller volume, less field using, simpler to be operated, more flexible monument and less secondary pollution. SBR was much different from traditional sewage treatment technology that the time division mode instead of the space segmentation mode, Unsteady biochemical reaction instead of the bistable biochemical reaction, Static ideal settling instead of the traditional dynamic precipitation in the SBR operation. Running in order and operating intermittently was its main characteristic. The core of this technology was the SBR reaction pool, which was combining with homogenizing, first sedimentation, biological degradation, secondary sedimentation and other functions but without a sludge return system. The wastewater treatment process for carbonated beverage industry provides a feasible way, has the good economic benefit, envi
