Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and exemplary embodiments.

[0032] refer to figure 1 , an electrolytic flocculation method for treating anthraquinone hydrogen peroxide production wastewater treatment system, including a sludge storage tank 10, and an oil separation buffer pool 1, a wastewater adjustment pool 2, an electrolytic flocculation equipment 3, and a coagulation sedimentation equipment 4 arranged in sequence , an intermediate pool 5, an air flotation machine 6, a clear water pool 7, an A / O reaction pool 8 and a membrane bioreactor 9.

[0033] Process wastewater is wastewater produced by anthraquinone hydrogen peroxide, and other wastewater is wastewater without oil slick and COD95%, the removal rate of suspended oil is 97%, the COD removal rate is >85%, the phosphorus removal rate is >80%, and the nitrogen removal rate is >40%. Ammonia nitrogen removal rate > 40%; coagulation sedimentation equ...

Abstract

The invention relates to a method for treating hydrogen peroxide production wastewater, in particular to a system and a method for treating anthraquinone-process hydrogen peroxide production wastewater by an electrolytic flocculation method, which are used for solving the problems of increased solid waste treatment cost, low automation degree, low cost and the like caused by generation of a large amount of iron sludge when anthraquinone-process hydrogen peroxide production wastewater is treated by a Fenton oxidation method. And the operation is tedious. The treatment system for treating the anthraquinone process hydrogen peroxide production wastewater through the electrolytic flocculation method comprises a sludge storage box, and an oil separation buffer tank, a wastewater adjusting tank, electrolytic flocculation equipment, coagulating sedimentation equipment, an intermediate water tank, an air flotation machine, a clean water tank, an A / O reaction tank and a membrane bioreactor which are arranged in sequence. Meanwhile, the invention further provides a method for treating the anthraquinone process hydrogen peroxide production wastewater through the electrolytic flocculation method.

Description

technical field [0001] The invention relates to a method for treating wastewater produced by hydrogen peroxide, in particular to a system and method for treating wastewater produced by anthraquinone hydrogen peroxide by electrolytic flocculation. Background technique [0002] As a green, non-polluting strong oxidant, hydrogen peroxide has been widely used in papermaking, textile, medical, chemical, electronics, food and many other industries. The anthraquinone method is currently the main method for the production of hydrogen peroxide, but a large amount of process wastewater will be generated during the production process. 100μm) and emulsified oil (<10μm). [0003] The Fenton oxidation method is the core method used to treat the wastewater produced by the anthraquinone hydrogen peroxide production in recent years. Free radicals are free radicals with strong oxidation ability, which can oxidize organic matter in wastewater, thereby effectively removing COD in wastewate...
