Technical field
The present invention relates to a kind of material for water treatment and engineering test verifying device more particularly to a kind of laboratory dyeing waste water
Except the device and method of antimony filtrate test.
Background technique
In fabrics printing and dyeing, polyester raw material polyester fiber synthesize when, terephthalic acid (TPA) synthesized with ethylene glycol need using
Catalyst containing antimony, such as antimony acetate, antimony glycol.It is can almost to help most efficiently with most economical catalyst at present
Realize absolutely conversion ratio.However, in the synthesis process, antimony element can evenly spread to polyester fiber with free state
In, when these fibers enter printing and dyeing mill or weaving mill further processing, in desizing and Alkali reduction process, free antimony will
It enters in waste water and deposits.Since " textile dyeing and finishing industrial water pollution object discharge standard " (GB4287-2012) requires gold
The limit value index for belonging to antimony is 100 μ g/L, and antimony may finally will appear exceeded after printing and dyeing, spray are knitted and accumulated layer by layer in waste water
The case where.Due to containing the poisonous and harmful substances such as a large amount of heavy metal antimony in dyeing waste water, the dyeing waste water of discharge beyond standards can be right
Environment causes serious pollution.
The processing method that dyeing waste water removes antimony at present mainly uses absorption method to be handled.However since waste water contains it
His a large amount of persistent organic pollutants, are easy to generate new byproduct of reaction, for by-product if being added directly adsorbent
Removal is a great problem again, and such water outlet also cannot usually reach national emission standard, therefore commonly wastewater treatment side
Method is filter column absorption method, but the screening of a variety of filtrates and the performance of filtrate are difficult to be determined, and become a great problem.
Researcher usually selects laboratory as the measurement place of media performance, this is because laboratory can be good at
On-site actual situations are simulated, to evade the problem of the following pilot scale is likely to occur, and meanwhile it is specific for media performance and filter column
The problems such as parameter optimization, can test for the live middle-end in later period and provide good data sample.So laboratory test is water process
And one ring of key of verification experimental verification.
Therefore, for these statuses, need to design a kind of suitable laboratory using test except antimony adsorbent adsorption effect
Filter device.
Summary of the invention

Step 2: different filtrates to be tested is respectively filled in four filter columns, is uniformly filled out on supporting layer；
Step 3: will contain antimony dyeing waste water and be passed through four filter columns, adjust filtering velocity and be filtered with flow, be adsorbed after filter
Dyeing waste water containing antimony afterwards；
Step 4: each filter column institute's water sampling is concentrated 10 times by conventional method and is used to detect；
Step 5: the water sample after concentration is subjected to antimony content detection by ICP instrument.
In step 1, by natural siliceous sand, 100-200 mesh is taken to dry, it is spare as filter column supporting layer, then take part day
Right minerals are dried through 100-200 mesh screen, or take the optimal natural mineral matter of part outlet effect, carry out different packing ratios
Test, filling proportion is respectively 40%, 50%, 60%, 70%.
In step 3, by stibium-containing wastewater with the flow access equipment of 10.972L/h, wherein the flow of each filter column is
2.743L/h, each filter column take a water sample every half an hour.
The beneficial effects of the present invention are:
The device of provided laboratory dyeing waste water containing antimony filtrate test according to the present invention, due to by directly by filtrate
Filter column is inserted, control filtering velocity is facilitated, is suitble to the determination of laboratory difference adsorption stuffing test material, and is fetched water conveniently, water outlet
Uniform effluent.
In addition, being not only suitable for laboratory screening different adsorbent and adsorbent due to the design using independent filter column
The determination of energy, while filter column can be directly replaced after filtrate saturation, without drawing clearly, greatly reduce the people in the following water factory uses
The use of power, while also facilitating monitoring of the water factory to device.
In addition, the device of print laboratory dyeing waste water containing antimony filtrate test provided by the present invention, operation is simple, out
