Suddenly the additional amount of ferrous sulfate and hydrogen peroxide is 2~the 4 ‰ of waste water total amount in (4), and the waste water total amount is wastewater treatment work
The total weight of skill fluidised form.
The level-one aerobic reaction time is more than or equal to 24 hours, and the second level aerobic reaction time is more than or equal to 12
Hour.
Aldehyde, ketone resin are produced as noncontinuity technique, and aldehyde, ketone resin waste water are divided into two classes by the present invention, and one kind is aldehyde, ketone
The washing effluent for the first time of production of resins, one kind are all other waste water during production.Then to washing effluent for the first time
It is pre-processed, neutralizes, reduces and wash high sulfate radical in effluent for the first time, polymer is intercepted, to reduce aldehyde, ketone resin waste water
Treatment agent expense and operating cost during processing；It is mixed again with two class aldehyde, ketone resin waste water and carries out multistage Fenton
Reagent reaction improve BOD5/CODcr value to 0.35 or more and carry out multi-stage aerobic reaction treatment so that final outflow water meet it is up to standard
Emission request.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
Specific embodiment
Below by specific embodiments and the drawings, the present invention is described in detail:
From fig. 1, it can be seen that the present invention is a kind of multistage processing of Fenton reagent method aldehyde, ketone resin waster water process, comprise the following processes:
(1) effluent of washing for the first time that gap produces is collected in a reaction tank, by the equimolar amounts of the concentrated sulfuric acid in production process
Lime is put into, is stirred lower reaction 2 hours, stratification, supernatant enters conditioning tank, and lower layer's solid-liquid object is pumped into separation of solid and liquid and sets
Standby, the liquid after separation of solid and liquid still enters conditioning tank, and solid enters sludge drying system；
