S42, electrolyte is added into waste water, and stir and electrolyte is well mixed in waste water；
S43, to the anode and cathodal closing being positioned in waste water, while start supersonic generator, and start simultaneously ultraviolet
Lamp.
Being passed through air can be to adding oxygen in waste water, and adds H2O2；So in ionization, ultrasound and ultraviolet light
When can preferably in degrading waste water harmful substance so that biochemical treatment load is lighter.
Preferably, supersonic generator is two in step S43, and the power of two supersonic generators is different,
And two supersonic generators work simultaneously.The supersonic generator of two different capacities is set to work simultaneously, it is so effective
It is good during than using single supersonic generator.
Preferably, negative electrode is stainless steel mesh negative electrode, anode is Ni―Ti anode and iron anode, and iron anode divides with Ni―Ti anode
The both sides up and down of negative electrode are not arranged on.Using this structure of double anode, degradation effect is better than common single anode.
Preferably, the sludge in step S6, S7, S8 in anaerobic pond, anoxic pond and Aerobic Pond is by taming
Arrive,
The step of domestication is：
A1, from wastewater treatment factory and office activated sludge is obtained, then stand and remove upper suspension, and by remaining cement mixing
Thing puts into aeration tank；
A2, the input dilution coking chemical waste water in pond, while proper nutrition liquid is put into, it is vexed quick-fried 20 hours, quiet afterwards heavy 1 hour, so
After remove supernatant；
A3, repeat step A2, and the concentration of the dilution coking chemical waste water put into every time gradually increases, until stopping after X times.
Domestication a period of time is carried out to the activated sludge of acquisition, so that the degradation effect of activated sludge is more preferable, and
The concentration of the dilution coking chemical waste water put into every time can all properly increase, and can thus enable activated sludge degradation treatment ability meeting
Slowly improve, finally reach ultimate attainment.
Preferably, anaerobic pond, anoxic pond and Aerobic Pond are that multiple ponds are together in series and set in step S6, S7, S8
Put.In this way, user can be facilitated to arrange three ponds, and conveniently three ponds are stirred.
