Specific embodiment
For content of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinates accompanying drawing
Describe in detail as follows：
As shown in figure 1, a kind of difficult degradation high-chlorine organic wastewater processing system based on electric flocculation is present embodiments provided, should
System is mainly made up of preliminary sedimentation tank 1, oxidation ditch 2, second pond 3, electric flocculation device 4, antisepsis contact tank 5 and storage basin 6.Wherein,
Oxidation ditch 2 includes anaerobic zone, anoxic zone and the aerobic zone being sequentially connected.The outlet of preliminary sedimentation tank 1 connects the water inlet of oxidation ditch 2
Mouthful, the outlet of oxidation ditch 2 connects the water inlet of second pond 3, and the outlet of second pond 3 connects the water inlet of electric flocculation device 4,
The outlet of electric flocculation device 4 connects the water inlet of antisepsis contact tank 5.The mud discharging mouth of second pond 3 is divided into 1:1 two branch roads,
The mud return mouth of anaerobic zone in one branch road connection oxidation ditch 2, the pipe of another branch road and the mud discharging mouth for being connected to electric flocculation device 4
Road bout is simultaneously connected to the mud inlet of storage basin 6.
Waste water initially enters preliminary sedimentation tank 1, through simple physics settlement action, removes small part float and pollutant
Afterwards, water outlet is carried out a biological disposal upon into oxidation ditch 2, sequentially enters anaerobic zone, anoxic zone and aerobic zone, utilize in oxidation ditch 2
Sludge system biological treatment effect removes most of pollutant.DO controls in anaerobic zone exist in below 0.1mg/L, anoxic zone DO controls
Below 0.3mg/L, aerobic zone DO are controlled between 2.0-2.5mg/L, are played biological carbon and phosphorous removal in 2 process section of oxidation ditch and are made
With the most pollutant of removal.2 water outlet of oxidation ditch enters second pond 3, and Jing after mud-water separation precipitation, water outlet enters electric flocculation
Device 4, by various action breaks hardly degraded organic substances such as electric flocculation, electro-redox, electric floating, water pollutant is entered
The reinforcing of one step is removed, and further reduces the index such as COD, TP, ss and colourity, and final reaction water outlet enters back into antisepsis contact tank 5 and enters
Places sodium chlorate disinfects heel row accepting/ordering system, and effluent quality can be stably reached《Urban wastewater treatment firm pollutant are arranged
Put standard》In GB18918-2002, one-level A is below the mark.
The returned sludge of second pond 3 is according to exteenal reflux 1:1 ratio is back to the anaerobic zone of oxidation ditch 2 again, supplements system
Biomass needed for system, another part returned sludge then together drain into storage basin with the precipitating sludge that formed in electric flocculation device 4
6, finally processed is carried out using sludge dewatering equipment.
The electric flocculation of electric flocculation device 4 process can saboteur's stability, which makes ring molecule open loop, macromole chain rupture
Characteristic can improve the biodegradability of waste water；If chloride ion content is high in water, water body electrical conductivity is high, electric flocculation processing method efficiency
Also can be higher and can appropriate reducing energy consumption；Simultaneously because chloride ion radius is little, penetration capacity strong, be easily adsorbed in anode and with gold
Category forms soluble compound, therefore the higher passivating film for making electrode surface of chloride ion content is more easy to perforation rupture, accelerates gold
The dissolving of category passivation layer.
Test example：
Certain sewage treatment plant intakes based on industry water in industry park, and hardly degraded organic substance is more, and in water, chloride ion contains
Amount is in 4000mg/L or so.The Sewage Plant chooses oxidation ditch as biological treatment according to prior art, and advanced treating is adopted
Be traditional coagulation sedimentation method for adding flocculant.Transformation is being carried out using Waste Water Treatment of the present utility model
Afterwards, under same secondary clarifier effluent water quality situation, system effluent quality has and is obviously improved：As shown in Figures 2 and 3, electric flocculation
4 water outlet COD of device can be controlled in below 30mg/L, and water outlet ss can be controlled substantially in 5mg/L or so；And effluent color dilution is reduced
To 8 or so, the clearance of each pollutant improves.
Although being described to preferred embodiment of the present utility model above in conjunction with accompanying drawing, this utility model is not
Above-mentioned specific embodiment is confined to, above-mentioned specific embodiment is only schematic, is not restricted, ability
The those of ordinary skill in domain under enlightenment of the present utility model, without departing from invention objective and scope of the claimed protection feelings
