Organophosphorus wastewater treatment process

Abstract

The invention discloses an organophosphorus wastewater treatment process. The process comprises the following steps: S1, pumping organophosphorus wastewater into a filter by a pump, and filtering outsolid impurities in the organophosphorus wastewater by a filter; S2, filling a catalytic oxidation system with a catalytic oxidation filler in advance; S3, pumping the organophosphorus wastewater subjected to solid impurity removal into the catalytic oxidation system, pumping active oxygen water into the catalytic oxidation system, reacting the catalytic oxidation filler and the active oxygen water to generate hydroxyl free radicals, and quickly converting organophosphorus in the organophosphorus wastewater into phosphates by the hydroxyl free radicals; and S5, pumping the treated liquid in the catalytic oxidation system into a plate-and-frame filter press to obtain a filter cake and a clear liquid, pumping the clear liquid into an advanced treatment system filled with resin, adsorbing residual phosphorus in the clear liquid by the resin, and detecting the total phosphorus content of phosphates in the clear liquid to be 0.5mg / l. The process has the advantages that the total phosphoruscontent of phosphates in the wastewater can be reduced to 0.5mg / l, the treatment procedures are few, and the treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of organic phosphorus wastewater treatment, in particular to an organic phosphorus wastewater treatment process. Background technique [0002] Organic phosphorus wastewater comes from the production wastewater of flame-retardant fabrics in the printing and dyeing industry, and the total phosphorus content in the wastewater is as high as 300 mg / l or more. Due to the stability of organic phosphorus, it is difficult to meet the discharge standard by traditional biochemical treatment, and due to factors such as domestic economy and technology, a large part of organic phosphorus production wastewater is even discharged directly without any treatment, causing serious damage to the environment, especially water bodies. Pollution. Therefore, the state stipulates that the total amount of phosphate phosphorus in the discharged wastewater must be reduced to less than 1 mg / l (GB8978-1996), in order to meet the discharg...
