Abstract

The invention discloses a treatment system for bromine-containing organic wastewater, belonging to the technical field of wastewater treatment service. The treatment system comprises an anaerobic tankand an aerobic tank, wherein an ozone reaction tower is arranged between the biochemical anaerobic tank and the aerobic tank to ensure that a part of biochemical organic matters in the wastewater preferentially undergo a hydrolytic acidification reaction; a sedimentation tank is also arranged between the anaerobic tank and the ozone reaction tower; and a buffer tank is arranged between the ozonereaction tower and the aerobic tank. According to the invention, the ozone biochar reaction tower is arranged between the biochemical anaerobic tank and the aerobic tank, so a part of the biochemicalorganic matters in the wastewater are ensured to undergo the hydrolytic acidification reaction preferentially; the rest macromolecular organic matters difficult to biochemically treat are treated through ozone oxidation and aerobic active bacteria successively, so a large amount of ozone consumption is saved, a perfect sludge backflow and treatment system is provided, wastewater concentrations required by sludge treatment in each biochemical stage is ensured, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to a bromine-containing organic wastewater treatment system, which belongs to the technical field of wastewater treatment services. [0002] technical background [0003] The production process of tetrabromobisphenol A will produce a large amount of high-concentration organic wastewater, which contains a large amount of refractory organic matter. At present, most of the bromine-containing wastewater in my country has backward treatment technology, aging equipment, and low treatment efficiency, which cannot meet national or local requirements. With the stricter new sewage discharge standards formulated, the treatment of bromine-containing wastewater has become an urgent problem to be solved. Contents of the invention [0004] The purpose of the present invention is to solve the problems of outdated bromine-containing wastewater treatment process, aging equipment, low treatment efficiency, and inability to meet the more stringent ne...
