Falling influences polluter precipitation biochemical and difficult to degrade in waste water, the biodegradation tank adds in aerobic autotrophic type microorganism
Group, the biodegradable tank of air blower blowing mouth connection provide sufficient oxygen for microorganism in biodegradable tank, and described two is heavy
Tank is dropped by controlling the residence time after the suspended active sludge settling separation during microbial degradation pipe is discharged back to microorganism
Xie Guanzhong, for waste water from flowing in air flotation tank, the air flotation tank connects medicine system, and waste water is consolidated by dosing in two heavy tanks
Liquid detaches, and air flotation tank water outlet is made to reach qualified discharge.
As further embodiment of the present invention：The adjusting tank adds in green vitriol as pH value adjustment agent and coagulating sedimentation agent.
As further embodiment of the present invention：The aerobic autotrophic type micropopulation is preferably nitrococcus and nitrifier.
As further embodiment of the present invention：The just heavy tank carries out sludge drying with the sludge discharge in air flotation tank, so
Sludge is transported outward afterwards, for industrial brickmaking.
As further embodiment of the present invention：The medicament of the medicine system dosing is matched for the 10%-15% of concentration by weight
The polypropylene amine medicament of the 1%-2% configurations of the aluminium polychloride medicament put and by weight concentration.
Compared with prior art, the beneficial effects of the invention are as follows：It is fewer for Packaging and Printing Enterprises wastewater flow rate, using this
Treatment process has various pollutants good removal effect, and process effect stability is at low cost, and management is convenient.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Attached drawing 1, a kind of package printing wastewater treatment process are please referred to, the printing wastewater sequentially enters adjusting by pipeline
Tank 1, just heavy tank 2, biodegradable tank 3, two heavy tanks 4, air flotation tank 5, printing wastewater are reached after processing reaches discharge standard
Mark discharge, the adjusting tank 1 are printing wastewater by volume：Sanitary wastewater=4:1, at the same by pipeline access printing wastewater with
Sanitary wastewater, carries out water quality equilibrium, and runoff investigation, the B/C ratios that sanitary wastewater can be improved in printing wastewater have more waste water
Biodegradability is conducive to the growth of multiple-microorganism, and the organic matter of printing wastewater is made to obtain homogeneous and Partial digestion, adjusts tank 1
For adjusting waste water water, balanced water quality and collecting and show storing wastewater, the just heavy tank 2 is being given up by medicine system 6
Dosing in water influences polluter precipitation biochemical and difficult to degrade for removing in waste water, subsequent aerobic anti-to be conducive to
Should, the biodegradation tank 3 adds in aerobic autotrophic type micropopulation, and the biodegradable tank 3 of 7 blowing mouth of air blower connection is
Microorganism provides sufficient oxygen in biodegradable tank 3, for making the polluter carried secretly in waste water, passes through the metabolism of microorganism
Activity is converted, and is allowed to innoxious, and the two heavy tank 4 is outstanding during microbial degradation pipe 3 is discharged by controlling the residence time
It is returned in microbial degradation pipe 3 after floating activated sludge precipitation separation, increases sludge concentration, the utilization of microorganism is made to reach best
Effect, for waste water from flowing in air flotation tank 5, the air flotation tank 5 connects medicine system 6, and separation of solid and liquid is carried out to waste water by dosing,
The water outlet of air flotation tank 5 is made to reach qualified discharge.
The adjusting tank 1 adds in green vitriol (Fe2SO47H2O) as pH value adjustment agent and coagulating sedimentation agent, green vitriol price
Cheap, high treating effect can significantly control the pH value of printing wastewater.
The aerobic autotrophic type micropopulation is preferably nitrococcus and nitrifier, under aerobic condition, the ammonia in waste water
Nitrogen is oxidized to nitrite and nitrate while consumes centainly under the action of aerobic autotrophic type nitrococcus and nitrifier
Basicity, this process are the nitrification stage：
Total nitration reaction formula：。
The just heavy tank 2 carries out sludge drying with the sludge discharge in air flotation tank 5, then transports outward sludge, for industry
Brickmaking, such as brickmaking.
Aluminium polychloride medicament of the medicament of 6 dosing of medicine system for the 10%-15% configurations of concentration by weight, i.e., 1
