Description
Technical field
The present invention relates to technical field of waste water processing, more particularly to a kind of bamboo product processing waste water processing system.
Background technology
With the fast development and a large amount of rises of bamboo product processing enterprise of bamboo industry, institute during bamboo product industry production
The a large amount of waste water for producing bring huge challenge to the ecological environment of China and the sustainable development of bamboo product industry.It is bamboo
Product waste water has the features such as organic concentration is high, pH value is low, colourity is big (CODCr20000mg/L, pH 3.0,1600 times of colourity),
The difficulty of discharged wastewater met the national standard is very big.
Chinese invention patent 201110220473.9 discloses a kind of method for treating wastewater from bamboo product, and bamboo product waste water is led to
Cross be diluted with water and chemicals addition control pH after carry out successively anaerobic expanded sludge bed reactor (EGSB), membrane bioreactor (MBR),
Nanofiltration device (NF) process, last qualified discharge.The invention is directed to the waste water from cooking in bamboo product process, by EGSB-
MBR group technologies remove in waste water 97% CODCr, the burden of subsequent treatment had both been reduced, and reasonably reclaimed processing procedure
The biogas of middle generation, using nanofiltration advanced treating biochemistry pool water outlet, makes final water outlet reach state sewage emission standard.
According to applicant react, the processing method in actual motion, outputted aerobic water dosing flocculation sediment, due to such waste water
Sludge is difficult sedimentation after dosing, and place is limited, without sufficiently large second pond, result in the water after processing and takes out of in a large number
Sludge, by expert discussion identify, employ ultrafiltration nanofiltration, in running, the rate of recovery of nanofiltration is arrived for 60%
Between 70%, partial concentration water needs agent-feeding treatment, but dosing less effective；Additionally, bamboo product needs in process of production addition
The unknown materials of many anti-corrosion class materials, certain pigment and other increase product qualities, make bamboo product waste water raw water quality
CODCrAt concentrations up to 26000mg/L～53000mg/L, B/C is sometimes as little as 0.04, and the condensed water obtained after process is again through oxidation
Still there is inverse phenomenon after the even various experiments such as charcoal absorption of (sodium hypochlorite, ozone) or chemical decolorization.In addition, steep
Foam problem always affects the main cause of biochemical normal operation, in order to ensure the normal operation of aerobic system, gesture necessary guarantee
Enough dissolved oxygens, but when aeration reaches to a certain degree, the foam a large amount of overflows of meeting again constantly affect plant area's health, more can shadow
Ring the passing masses of periphery.Jing is tested repeatedly, and defoamer is sterilization component, it is impossible to used, and is disappeared using Aerobic Pond mixed liquor waterpower
Bubble, also not substantially, foam COMPARISON OF CHARACTERS is sticky for effect, it is difficult to crush, foam and both restrictions aerobic also leverage technique
The normal operation of rear end.
Chinese invention patent 201510179103.3 discloses a kind of bamboo product Waste Water Treatment, including waste water is adjusted
Pond, reinforcing flotation tank, ozone oxidation sedimentation basin, deflector type anoxic anaerobic reation pool, aerobic contact oxidation pond, second pond and sand filtration
Pond；Reinforcing flotation tank sequentially consists of silt particle area, mixed zone and Disengagement zone；Ozone oxidation sedimentation basin includes aeration mixed zone

Contact-oxidation pool is provided with water inlet pipe, water distribution pyrometric cone and aeration regulator control system；The adjusted pond of waste water enters reinforcing flotation tank and goes
Except scum silica frost, then into ozone oxidation sedimentation basin, pollutant is oxidized and decomposes waste water, enters back into deflector type anoxic anaerobic reaction
Pond, aerobic contact oxidation pond carry out anoxic, anaerobic and aerobic reaction, the qualified discharge Jing after precipitation and filtration.
Although above-mentioned bamboo product Waste Water Treatment is strong by arranging between wastewater equalization pond and ozone oxidation sedimentation basin
Scum silica frost in changing flotation tank to remove waste water, and then concentration of suspension in waste water is reduced, chroma in waste water is reduced to a certain extent,
But waste water is sequentially entered into deflector type anoxic anaerobic reaction Jing after the pollutant in ozone oxidation sedimentation basin oxidation Decomposition waste water
Pond, aerobic contact oxidation pond carry out anoxic, anaerobic and aerobic reaction, numerous known, and in the waste water Jing after anaerobic reaction one is contained
Quantitative anaerobic bacteria flora, it all rises to inhibitory action to the aerobic bacteria in aerobic reaction, so as to reduce aerobic reaction efficiency and anti-
Effect is answered, and Aerobic Pond aeration rate is big, it is impossible to bubble-related issues described above are solved, meanwhile, the processing system outputted aerobic water is still
Second pond is introduced after needing dosing to be flocculated carries out precipitate and separate, and as stated above, its sludge flocculation sedimentation effect is poor,
And in actual production process, because place limits, there is certain difficulty, and high cost in the setting of second pond, and then after processing
The condensed water yield for obtaining is larger.
The content of the invention
The purpose of the present invention is to overcome the defect existing for above-mentioned bamboo product wastewater treatment, there is provided a kind of stable, effect
