Abstract
The invention relates to a method for reusing terylene dispersing dye dyeing waste water. The method comprises the following steps: adopting a water collection tank, carrying out physical and chemical precipitation, carrying out cartridge filtration, carrying out ultrafiltration, reusing in a clear water workshop, carrying out entering of concentrated waste water into a biochemical pool to be re-treated, and discharging after achieving the standard. In dye dyeing, high temperature leveling agent content in waste water is directly related to a COD factor, and effective degradation is difficultly achieved through the existing method. With the method, 80% of the high temperature leveling agent in the waste water can be recovered and reused, such that a production cost is effectively reduced, environmental pollution is reduced, and commissioning application effectiveness is quick.
Description
Technical field
The present invention relates to a kind of method of wastewater treatment and reuse, relate in particular to a kind of method that high temperature levelling agent in the terylene disperse dyeing wastewater is reused.
Background technology
Along with the reinforcement of environment protection dynamics, utilization of waste material and waste water recycling become the key element of human survival.In all textile wastes, dyeing terylene waste water is the most difficult.By current requirement, network and need the 200COD discharge, reclamation rate reaches 50% new standard.This area roughly processing technological flow commonly used is:
Water collecting basin---anaerobism---physico-chemical precipitation---alkali readjustment---acidolysis pond---biochemistry---just heavy---two is heavy---discharge.---gac---ultrafiltration---reverse osmosis membrane etc. that if need reuse, also will increase sand filtration.
Sand filtration and activated charcoal filter effect are absorption and resolving, do not clean also in 1 year and can not block up container.Without holding back phenomenon from another perspective, to the bacterioprotein after biochemistry, a small amount of dyestuff, the terylene oligopolymer produced in dyeing, without holding back phenomenon, dark meeting produces white point in the reuse process, and light color can produce color dot.
Summary of the invention
The object of the present invention is to provide a kind of method that reuses the terylene disperse dyeing wastewater, on the basis that existing terylene disperse dyeing wastewater is processed, by most high temperature levelling agent is able to sufficient recycling, improve the pollution of dyeing to environment.
The present invention is a kind of method that reuses the terylene disperse dyeing wastewater, and step is as follows successively:
------security personnel filter---ultrafiltration---reuse between clear water car---density wastewater during advances biochemistry pool to be processed again---qualified discharge to physico-chemical precipitation to water collecting basin.
Water collecting basin collects waste water and regulates.
The physico-chemical precipitation process is in waste water, to add flocculation agent (to be commonly called as: dosing) precipitate.Flocculation agent directly utilizes the raw waste water facility.Adjust pH value, with ferrous sulfate or polymerize aluminum chloride.Add a small amount of polymeric amide to remove dyestuff and the sizing agent that 80%-90% is harmful to dyeing quality.And flocculate to remove not fall, the useful COD high temperature levelling agent of dyeing reuse is retained by it.
Security personnel's filtration step, adopt cartridge filter, comprises that 6-11 theoretical precision is the ultrafiltration bag of 1 micron, and operating pressure 0.2-0.4MPa, hold back dyestuff, thickness oligopolymer and sizing agent.
Ultra-filtration process, used 8 inches polysulfone material, and it holds back molecular diameter is 0.01 micron, and dyestuff, oligopolymer and sizing agent are further held back.The dosing of flocculation sediment process blocks in situation even its objective is also can be held back, and guarantees the reuse water quality.
Workshop reuse 80%, all the other 10-20% advance biochemistry pool process up to standard after, discharge.
The inventive method has embodied in fact to the taking full advantage of of original treatment unit, and has greatly reduced replacement investment, has solved the problem of lack of space.Original anaerobic pond or acidolysis pond are changed into to reuse pool and ultrafilter pond.
In the terylene disperse dyeing, in waste water high temperature levelling agent when the materialization dosing is flocculated, the 0-20 no matter how many COD of dosing only descend.The COD that after processing in actual treatment, COD500-1000 also just in time produces near the consumption of high temperature levelling agent.High temperature levelling agent can reclaim and reuse, and dyes a small amount of interpolation of light color, and other can not add.Save the levelling agent of 80% left and right, the application instant effect of going into operation.
The inventive method solves former processing biochemistry pool device insufficient section and too short defect of the residence time, reuse 80-90% waste water.The biochemistry pool residence time can increase by 4 times-9 times and substantially can guarantee emission request
The inventive method does not add any medicament, approximately 0.2 yuan/ton of its processing cost
Reduce the laid down cost of biochemistry pool.High temperature levelling agent COD is in 500 biochemical COD decline every day 60 left and right, left and right, and when as high as concentration, COD2000 can cause a large amount of bacterium death in left and right.Its particle of waste water after ultrafiltration reaches the cohesion that dispersed system can prevent dyestuff, prevents the generation of color dot.
Embodiment
Embodiment
A kind of method that reuses the terylene disperse dyeing wastewater, step is as follows:
Collect dyeing waste-water in wastewater equalization pond, add flocculation agent (aluminium chlorohydroxide or ferrous sulfate) precipitation, the gained precipitation can be passed through the pressure filter press filtration, and the remaining liquid of press filtration flows back to wastewater equalization pond, and press filtration mud is recycling, as: the Route for pedestrians brick.
Then, supernatant liquor is proceeded to cartridge filter to be filtered, cartridge filter, comprise that 6-11 theoretical precision is the ultrafiltration bag of 1 micron, operating pressure 0.2-0.4MPa, then using and holding back molecular diameter is that 8 inches polysulfone material of 0.01 micron are carried out ultrafiltration, and dyestuff, oligopolymer and sizing agent are further held back.
Reuse 80% high temperature levelling agent, gained density wastewater during advance biochemistry pool and carry out biochemical treatment, discharge to the emission standard that meets COD with degraded residue 10%-20% high temperature levelling agent.
Use the technological transformation upgrading of the present embodiment method to old factory, utilize the raw waste water treatment facility, occupied ground is little, infusion of financial resources less, instant effect.
The method changes create beneficial result row from energy-conservation.Example: 20 8 inches ultrafiltration produce water 10-15 ton/hour, 1 ton of productive power of 5.5 kilowatts of every products of motor is half degree electricity approximately.And discharge a water, enter 3 yuan/tons of pipe network need, 2.6 yuan/tons of tap water water rates, water generates benefit per ton (3+2.6)-0.3=5.3.
The method is effectively saved the about 80%-90% of cost of high temperature levelling agent, reduces to pollute and accomplishes the less contamination environment, turns waste into wealth.
