Description
Technical field
The invention belongs to industrial waste water treatment, more particularly to a kind of printing and dyeing industrial waste water processing engineering project
Carry mark remodeling method.
Background technology
It is increasingly strict with the environmental requirement of the country and people, the pollutant emission standard of textile printing and dyeing industry waste water also phase
It should improve.Wherein, added tight to COD, BOD in direct discharging of waste water limit value5, suspended matter, many indexs such as ammonia nitrogen and sulfide
Requirement, also add the index limits such as total nitrogen, total phosphorus, adsorbable organic halogen (AOX) and total antimony.Direct emission COD limit values
It is increased to 80mg/L from the 100mg/L in 92 years standards, and is flowed in environmentally sensitive area, such as Taihu Lake of textile dyeing and finishing Nesting Zone
Domain, it is desirable that be less than 60mg/L.But be mainly materialization+secondary biochemical treatment technique in the engineering of printing and dyeing industrial waste water processing at present,
Water outlet COD is generally at 140mg/L or so (Chinese water supply and drainage, 2011,27 (15) 32-34) after it is handled, it is clear that cannot reach
Newest, more stringent direct emission standard, needs further advanced treating.Therefore, for the waste water of materialization+secondary biochemical
Engineering is handled, or is having advanced treatment process section later, but water outlet cannot still reach discharge standard, it is necessary to carry out work
Mark transformation is proposed in journey.Nowadays, the major depth treatment technology of dyeing waste water has UF membrane, absorption, advanced oxidation and efficiently life
Object technology etc..But although membrane separation technique high treating effect is used, it is fast etc. that small treating capacity, fouling membrane and membrane module loss may be present
Lead to problem of high cost；Advanced oxidation processes also have removal effect well, but complex process, operation hardly possible, may cause secondary
Pollution；The general structures of high-performance bio technology take up an area greatly, and construction cost is high, are not suitable for having engineering further conversion；Absorption method work
Skill is simple, strong operability, is suitable for the industrial wastewater of pollutant complexity.Now common sorbing material is activated carbon, price compared with
Height causes operating cost high, is not suitable for large-scale industry wastewater treatment.Therefore, and if a kind of suction wide, of low cost with source
The big adsorbent of attached amount, will be significant for the transformation and upgrade of existing engineering.
Invention content
The mark that carries that engineering project is handled technical problem to be solved by the invention is to provide a kind of printing and dyeing industrial waste water is transformed
Method, this method is of low cost, operability is strong, high treating effect, and water outlet COD≤60mg/L, coloration≤10 times meet spy
Other direct emission standard.
A kind of printing and dyeing industrial waste water processing engineering project of the present invention carries mark remodeling method, including：
Printing and dyeing industrial waste water is handled into the secondary effluent in engineering, through dynamical system by activated coke adsorption column, absorption is gone
Except a degree of COD, coloration and ammonia nitrogen, until effluent quality is no more than newest discharge standard, wherein being adsorbed by activated coke
The mode of column is that from bottom to top, activated coke dosage is 0.0001~0.5tActivated coke/m3 Waste water。
The secondary effluent COD is 70~200mg/L, and coloration is 10~200 times, and temperature is 2~50 DEG C.
The activated coke is the irregular particle activated coke that grain size is 1~8mm.
The activated coke is made of at least one of bituminous coal, anthracite, lignite.
The empty bed residence time of the activated coke adsorption column is 1~100min.
The water-out manners are discharged for overflow.
The effluent quality index is：COD is 10~60mg/L, and coloration is 1~10 times；Effluent quality meets direct emission
Standard.
The effluent quality is unsatisfactory for discharge standard, then conversion is to another activated coke adsorption column, after activated coke adsorption saturation
Through completely cutting off air heating, regeneration, reuse, operation is worked alternatively with this.
The activated coke of the adsorption saturation is heated to 150~800 DEG C in nitrogen protection atmosphere, and activated coke is made to obtain again
Raw, tertiary recycling rate is more than 90%.
The parameters and activated coke material of the activated coke adsorption column and another activated coke adsorption column are completely the same, alternately
Cycle operation.
The present invention chooses the activated coke that mesoporous is flourishing, surface functional group is abundant, and two sets of activated coke fixed beds in parallel are made
Adsorbent equipment works alternatively；By the secondary effluent of industrial wastewater, from bottom to top by adsorption column, from outflow water.The present invention exists
After existing processing engineering, by the suction-operated of activated coke, the macromolecular dirt difficult to degrade in industrial wastewater secondary effluent is removed
Object is contaminated, so that useless Organic substance in water, coloration and ammonia nitrogen etc. is effectively removed, meets the requirement of discharge standard raising.
Advantageous effect
(1) simple possible of the present invention, of low cost, activated coke can repeatedly regenerate, also can be directly as fuel, no after discarding
Hazardous solid waste is generated, secondary pollution is avoided；
(2) present invention water outlet COD≤60mg/L, coloration≤10 times, meet special direct emission standard；
(3) engineering construction investment of the present invention is few, has a wide range of application, and operation, maintenance cost are low, and effect stability, has good
Environment well, economic and social benefit.
