Description
Technical field
The present invention relates to field of waste water treatment, the device of especially a kind of low energy consumption high-efficiency intensive treatment dyeing waste water and its
Operation method.
Background technique
China is textile industry big country, and textile printing and dyeing industry is the industry of typical high water consume and high energy consumption.And urban development and
The raising of living standards of the people promotes the discharge of dyeing waste water increasing.Dyeing waste water is the discharge of dyeing process Zhong Ge workshop section
The general name of waste water, used in chemical agent and dyestuff be dyeing waste water major pollutants.There are many containing in dyeing waste water
Hardly degraded organic substance and heavy metal, it is big with coloration, biodegradability is poor, water quality and quantity variation greatly and the spy with bio-toxicity
Point.It is handled using traditional single method, printing and dyeing wastewater to reach standard can not be made to discharge.Below standard direct discharging of waste water enter river and
When lake, it will cause poisonous and hazardous substance accumulation in water body, destroy water ecology and balance and cause drinking water safety problem.
Dyeing waste water is difficult to the utilization that is degraded by microorganisms, Zhi Nengtong containing complicated hardly degraded organic substance, larger molecular organics
The mode for crossing additional carbon carries out denitrification, increases cost for wastewater treatment.Aerobic Process for Treatment is combined using hydrolysis acidification pretreatment
Group technology, the biodegradability of dyeing waste water can be increased by anaerobic hydrolysis process, the larger molecular organics of high concentration are dropped
Solution is small organic molecule.By subsequent aerobic combination technique, the small organic molecule generated during acidification hydrolization is made
It is denitrifying carbon source by further mineralising, achievees the purpose that dyeing wastewater through organic matter removes.Azo dyes is de- in dyeing waste water
It removes, can achieve the purpose that efficient removal using adsorbent or advanced oxidation agent.But the desorption of azo dyes is difficult to realize, and
And the regeneration of adsorbent needs additional investment, and regenerated adsorbent reduced service life.This is difficult to adsorbent
Large-scale application in printing-dyeing waste water treatment process.The reaction condition of strict control is needed using advanced oxidation agent, and for water quality
Water changes for dyeing waste water greatly, and advanced oxidation agent is difficult to apply in actual dying treatment process.Use anaerobism-
Aerobic combination Biochemical method dyeing waste water, the strong reducing property environment degradable larger molecular organics that can use in anaerobic processes are
Small-molecule substance provides organic carbon for aerobic process and carries out denitrification processing.Bioanalysis for other processing methods compared with being easier to grasp
Make and safeguard, and its operating cost is lower, thus it is possible to vary the problem that energy consumption is high for printing-dyeing waste water treatment process, at high cost.
To guarantee disposal effect of dyeing wastewater and saving processing cost, more thinkings are living using anaerobic-aerobic now
Property sludge carry out wastewater treatment.Such as application No. is 200810242897.3, publication date is on 06 17th, 2009 practical
Patent of invention discloses a kind of method of dyeing waste water high-efficiency biological strengthening treatment.The invention is high, complicated composition for coloration
Dyeing waste water carries out intensive treatment using active carbon combination anaerobic-aerobic activated sludge process.The technique is by the print after hydrolysis acidification
Dye waste water is passed through anaerobic-aerobic pond, distinguishes two sections in anoxic and adds methanol to realize efficient denitrification, adding concentration in aerobic zone is
200mg/L Powdered Activated Carbon is to improve decolorizing effect.But it is small using organic loading that activated sludge process is born, can generate it is more
Excess sludge, and extraneous methanol and add active carbon and increase cost of water treatment investment, and the hot recycling of active carbon can produce
Raw a large amount of energy consumptions.Chinese Patent Application No. 201310732911.9, publication date are on 04 09th, 2014, disclose a kind of printing and dyeing
The method of Sewage advanced treatment, comprising the following steps: adjust azo dye wastewater pH value, waste water is passed through in reduction pond using work
Change aluminum reduction azo bond；Wastewater supernatant fluid after reduction is passed through in oxidation pond, oxidation reaction is carried out using Fenton reagent；
Waste water after reaction is passed through neutralization precipitation pond to be separated by solid-liquid separation；Supernatant is passed through adsorption tank to take off using active carbon
Color, such process flow are relatively easy, it is ensured that coloration and organic matter removal effect.These processing techniques are often through additional
Reagent improves the decoloration degree of dyeing waste water, simplifies process flow, but there are severe reaction conditions, operational administrative is complicated, operation at
This high problem, Practical Project applicability are poor.
Summary of the invention
Goal of the invention: the technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of low energy consumption
The device and its operation method of efficient intensive treatment dyeing waste water.
In order to solve the above-mentioned technical problems, the present invention provides a kind of dresses of low energy consumption high-efficiency intensive treatment dyeing waste water
It sets, including conditioning tank, acidification pool, anoxic pond, aerobic tank, secondary settling tank and the sedimentation basin being sequentially communicated, and secondary settling tank passes through pipe
Road is connected to anoxic pond；
Middle part is equipped with fixed filler in acidification pool, and acidification pool is connected to charcoal grug feeding jar and is used to add biology to acidification pool
Charcoal；The enhanced hydrolysis acidification pool that the present invention uses has added charcoal particle, and charcoal provides for hydrolysis acidification bacterium and inhabites field
Institute forms biomembrane, and partly soluble charcoal can provide necessary microelement for microorganism, guarantee the work of microorganism
Property.
The outer wall of acidification pool is equipped with permanent magnet.Permanent magnet outside pond body can effectively improve microbial hydrolytic enzyme activity
Property, enhance microorganism to the hydrolysis acidification ability of particulate organic matter, while improving the shock resistance energy of enhanced hydrolysis acidification pool
Power；Furthermore charcoal has porosity, can further strengthen the Adsorption of coloration.
In the present invention, acidification pool is reinforced anaerobic digester, and the permanent magnet magnetic field strength of outer wall is 80-120mT.
