Description
Technical field
The utility model relates to a kind of sewage treatment equipment, especially relates to a kind of improved Fenton sewage treatment equipment.
Background technology
For the waste water of difficult for biological degradation, generally adopt high-level oxidation technology to handle.The characteristics of high-level oxidation technology are that they all can produce the OH radical.Because the redox potential of OH radical (2.80 v) be much higher than traditional oxygenant (as 1.77 v of 1.36 v of chlorine, ydrogen peroxide 50 and ozone 2.07 v), and it and organic reaction rate constant are 10
8 ~ 10M
-1s
-1Between, so it can decompose the organism of common oxygenant intractable rapidly.In various high-level oxidation technologies, the Fenton method comes into one's own because of easy and simple to handle, with low cost day by day.The Fenton process generally comprises following four-stage: i.e. pH regulator, oxidizing reaction, neutralization and coagulation and precipitate phase.But, can produce more mud at precipitate phase because Fe (II) ionic adds.For remedying these deficiencies of common Fenton method; People propose electrochemical process and combine with the Fenton method (being the Fenton method), when electrochemical process and Fenton method combine, can produce synergistic effect; Improve the clearance of COD thus, reduce the generation of mud simultaneously.Fenton comprises the four-stage of Fenton equally.
In the Fenton oxidizing reaction stage of even flow, the bubble that cathode and anode produces can form significant foam and scum silica frost from liquid level with the suspended matter band in the waste water, and is deposited on the liquid level, thereby has influenced the rapid diffusion of gas.If what adopt is the electrolyzer of band aerator, foam and scum silica frost more are easy to generate.Along with the carrying out of reaction, foam and scum silica frost constantly increase, and then have wrapped up the tie point of lead and battery lead plate, have caused potential safety hazards such as spark or blast.
