(2) High volume load and sludge load
Today's Nano TiO 2 Photocatalytic reactors are mainly packed bed photocatalytic reactors, nano-TiO 2 Photocatalytic oxidation technology has good chemical stability and thermal stability, simple structure, easy operation, no secondary pollution, and the catalyst is cheap, non-toxic, and reusable. It is an efficient green technology, but currently the nano TiO 2 Research on photocatalytic oxidation technology is in a small-scale experimental stage, and individual nano-TiO 2 Photocatalytic reactor treatment of wastewater can not meet the discharge requirements

Abstract

The invention relates to an efficient sewage combined treatment method and a device. The combined treatment method is to adopt the sewage combined treatment device, which combines a photo-catalytic reactor with a jet loop high efficiency biological reactor. Sewage, in particular organic industrial wastewater with high concentration and low biodegradability is pre-treated by the photo-catalytic reactor at first to improve the biodegradability of the wastewater and then enters the jet loop high efficiency biological reactor for the aerobic activated sludge treatment to improve the sewage treatment efficiency and obtain good treatment effects. The combined device is to connect the photo-catalytic reactor which is a nano TiO2 photo-catalytic reactor to a water inlet pipe of the jet loop high efficiency biological reactor. The device of the invention has the advantages of compact structure and strong load resistance. The combined treatment method of the invention is provided with good treatment effects.

Description

technical field [0001] The invention relates to a method and device for treating industrial sewage, in particular to a sewage combined treatment device combining a nano-titanium dioxide photocatalytic oxidation reactor and a jet circulation high-efficiency bioreactor, belonging to the technical field of environmental protection industrial sewage treatment. Background technique [0002] The jet loop high-efficiency bioreactor HCR (High Performance Compact Reactor) is composed of a water ejector, a circulation pump and an integrated reactor. It combines high-speed jet aeration, phase enhancement transfer, turbulent shear and other technologies. The mass transfer efficiency of oxygen is relatively high. As a new aerobic biological treatment technology, it has the following advantages: (1) High oxygen transfer efficiency. The jet aeration method and the turbulent shear caused by it make the air oxygen transfer efficiency of the reactor high, the conversion utilization rate of a...
