Abstract
The invention relates to a treatment technology of wastewater generated in the preparation of hydrogen peroxide from anthraquinone. The technology comprises the following steps: adding a flocculating agent and an antifoaming agent to wastewater obtained in the preparation of hydrogen peroxide from anthraquinone, and stirring for 12-24h to complete the wastewater treatment. Compared with the prior art, the technology makes the COD of water discharged from a water discharge end decrease from original 250ppm to below 20-30ppm and SS decrease to about 20-30mg/l after long time wastewater treatment, meets wastewater emission indexes, has a very stable effect, and has no untoward effects on the whole wastewater treatment system.
Description
Technical field
The present invention relates to a kind of waste water treatment process, especially relate to the waste water treatment process that a kind of anthraquinone is prepared hydrogen peroxide.
Background technology
Hydrogen dioxide solution production by anthraquinone process is one of the most ripe method of hydrogen peroxide of producing in the world at present, and the hydrogenation catalyst that hydrogen dioxide solution production by anthraquinone process adopts is palladium series catalyst at present substantially, comprises fixed bed catalyst and suspension bed catalyzer.But, in the anthraquinone technique of preparing hydrogen peroxide, the waste water producing mainly comprises the working solution and the sanitary wastewater that contain a large amount of organic solvents, 700 district's Waste Water Treatments are to process waste water, the master operation that reduces waste water COD, reaches 5000～6000ppm from the waste water COD of plant area, after traditional Fenton art breading, water side leading indicator COD drops to about 250ppm, and suspended solid SS is in 250mg/l left and right but still cannot meet the index that requires of draining.
Summary of the invention
Object of the present invention is exactly to provide a kind of effect stability in order to overcome the defect that above-mentioned prior art exists, and the anthraquinone that whole Waste Water Treatment is had no adverse effects is prepared the waste water treatment process of hydrogen peroxide.
Object of the present invention can be achieved through the following technical solutions:
Anthraquinone is prepared a waste water treatment process for hydrogen peroxide, prepares in the waste water that hydrogen peroxide obtains and adds flocculation agent and defoamer to anthraquinone, after stir process 12-24h, completes the processing to waste water, and the waste water after finishing dealing with is discharged.
Adopting anthraquinone to prepare hydrogen peroxide is Fenton technique.
The flocculation agent adding is quaternary ammonium salt flocculation agent.
The defoamer adding is silicone antifoam agent.
Compared with prior art, the present invention is through after the wastewater treatment of long period, and discharge ends COD is dropped to below 20-30ppm by original 250ppm, SS drops to 20-30mg/l left and right, met waste water drainage index, and effect is very stable, and whole Waste Water Treatment is had no adverse effects.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment
The present invention is on the basis of traditional Fenton technique, carry out further technological improvement, prepare the wastewater treatment of hydrogen peroxide for anthraquinone, prepare in the waste water that hydrogen peroxide obtains and add quaternary ammonium salt flocculation agent and silicone antifoam agent to anthraquinone, after stir process 12-24h, complete the processing to waste water, the waste water after finishing dealing with is discharged.The waste water obtaining by processing of the present invention, discharge ends COD is dropped to below 20-30ppm by original 250ppm, and SS drops to 20-30mg/l left and right, met waste water drainage index, and effect is very stable, and whole Waste Water Treatment is had no adverse effects.
