25 are connected with driving equipment, and black box 24 ensures the seal that rotating shaft 25 is connected with micro-electrolysis reaction pond 4.Rotating mass rotating speed
For 60～80rpm, paper waste time of staying in the micro-electrolysis reaction pond 4 be.
In one rotation period, first, Fe-C filler assembly 9 is immersed in micro-electrolysis reaction pond 4, due to Fe-C filler group
Each side of part 9 has loose structure, and waste water is entered in Fe-C filler assembly 9 quickly, and carries out in Fe-C filler ball surface micro-
Cell reaction；
With the carrying out for rotating, Fe-C filler assembly 9 leaves the water surface and gets into the air, and occurs in Fe-C filler ball surface
Solid, liquid, gas three-phase chemical reaction；
In rotation process, phase mutual friction and exchange position between Fe-C filling ball, are detained and absorption is in Fe-C filler ball surface
Water and Fe-C filler assembly 9 carry water and constantly drop to the water surface from Fe-C filler assembly 9, realize oxygenation in falling process；
Subsequently Fe-C filler assembly 9 is reentered in the waste water of micro-electrolysis reaction pond, repeats said process；
Micro-electrolysis reaction pond 4 controls chemical feeding quantity of the chemical feed pipe 1 to micro-electrolysis reaction pond 4 by the first pH meter 5, maintains micro- electricity
PH in solution reaction tank 4 is less than 6.
Micro-electrolysis reaction pond 4 controls the rotating speed of driving equipment by dissolved oxygen instrument 3, maintains the DO in micro-electrolysis reaction pond 4
Value is in 2～4mg/L.
During light electrolysis are carried out, in Fe-C filling ball, Fe is constantly separated out, and filling ball constantly reduces, and therefore, runs one section
After time, Fe-C filling ball in Fe-C filler assembly 9 need to be changed.During replacing, Fe-C filler assembly 1 and rotation are declined
The nut that electrolysis main body is fixed is turned on, and is proposed Fe-C filler assembly 9, is extracted the active multi-hole plate at 9 two ends of Fe-C filler assembly, i.e.,
The replacing of Fe-C filling ball and interpolation can be carried out, reinstalling rear Fe-C filler assembly 9 can be continuing with.
Paper waste enters folded plate flocculator 14 after the process of micro-electrolysis reaction pond 4, and folded plate flocculator 14 passes through the 2nd pH
Meter 12 controls the caustic dosage of chemical feed pipes 13, maintains the pH of folded plate flocculator 14 between 9～10,14 time of staying of folded plate flocculator
For 15～25min.Substantial amounts of Fe (OH) is formed in folded plate flocculator 143Floccule body, floccule body has larger specific surface area, tool
There is strong adsorption-flocculation effect.Paper waste after flocculation enters transition pond 17, and transition pond 17 has the hydraulics for relatively delaying,
10～15min of hydraulic detention time, flocculate in stable and strong adsorption insoluble matter in transition pond 17 and can constitute colourity not
The float such as soluble dye.Fe (OH) after absorption insoluble matter3Larger particles are formed, carries the waste water perforated flower of particulate matter
Inclined-plate clarifying basin 20,20 20～30min of hydraulic detention time of inclined-plate clarifying basin, the waste water after precipitation is entered after 19 water distribution uniformity of wall
Next stage reactor for treatment is entered through downflow weir 24 and drain pipe 23, the precipitation in swash plate 22 that falls is snapped down to sloping plate deposition at the bottom of pond
Portion, can be discharged by discharge pipeline 21.
The above is only the preferred embodiment of the present invention, it should be pointed out that：Ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
