Abstract

The invention initiatively provides a technical scheme for removing total organic carbon and organic halides in biochemical effluents, and belongs to an environment-friendly manufacturing process system. A treatment system for simultaneously removing the total organic carbon and the organic halides in the biochemical effluents comprises a water inlet pump, a fixed-bed oxidation reaction tank, modified diatomaceous earth-ferrous sulfate fillers, a hydrogen peroxide dosing tank, a dosing pump, a lift pump, a modified activated carbon adsorption tower, modified activated carbon and a drainage pump. After the biochemical effluents are treated by the treatment process, the pH of the biochemical effluents ranges from 6 to 8.5, the content of the total organic carbon ranges from 3.5mg / L to 13.2mg / L, and the content of the organic halides ranges from 0.1mg / L and 0.4mg / L.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a process technical scheme for total organic carbon and organic halides in biochemical effluent water. Background technique [0002] The total organic carbon and organic halides of industrial wastewater are still high after biochemical treatment, and direct discharge without treatment will endanger the environment. At present, industrial wastewater mainly adopts biochemical treatment technology, but the quality of effluent water after treatment is difficult to meet the requirements of pollutant discharge standards of various industries. Shanghai's "Comprehensive Wastewater Discharge Standard" (DB31 / 199 -2018) requires total organic carbon to be less than 15 mg / L and organic halides to be less than 0.5 mg / L. Using wet oxidation, nanofiltration, reverse osmosis and other processes to treat biochemical effluent has high cost and complicated operation, and is not...
