Formula.
Embodiment 1
A method of phenol wastewater produced by processing needle coke production technology, the specific steps are：
(1) filtered wastewater removes suspended matter and solid impurity therein；
(2) by the mixed fillers after activation loaded in glass column or stainless steel column；
(1) with constant flow pump control waste water flow through resin column carry out absorption remove phenol；
(3) resin column is impregnated with eluant, eluent, is reused after zeolite regeneration.
It is cloudy using the macroporous absorbent resin of polystyrene skeleton and the strong basicity of polystyrene skeleton in above-mentioned steps (2)
The mixed fillers of ion exchange resin.
In above-mentioned steps (2), volume ratio shared by macroporous absorbent resin is 70~85%.
In above-mentioned steps (3), it is 4~6 times of column volume/hours that constant flow pump, which controls waste water flow velocity,.
In above-mentioned steps (4), eluant, eluent is absolute ethyl alcohol, and soaking time is 1~3 hour, is impregnated twice.
This method is suitable for processing and contains phenol and nitrogen amide, and concentration is higher, waste water of the pH close to 10.
The method of Phenol-Containing Wastewater Treatment of the present invention, specific experiment process are as follows：
Refer to attached drawing 1,2,3,4,5, waste water is extracted with constant flow pump, 5 μm of filter plate is flowed it through, it is miscellaneous to be filtered to remove solid
Matter.By the mixed fillers after activation, (macroporous absorbent resin selects HZ-16 type resins, strong-base anion-exchange resin to select
D201 type resins；It is 20%) to fill column in diameter that wherein volume shared by HZ-16 types resin, which is volume shared by 80%, D201 type resins,
15mm, in the glass column of height 360mm.It is adsorbed by resin column with the flow velocity of 5mL/min with constant flow pump control waste water, often
Adsorption liquid is collected every 10min, the content of phenol in adsorption liquid is measured by high performance liquid chromatography.
Etc. resin adsorptions saturation after, i.e. when the phenol changes of contents of liquid chromatogram measuring is little stop absorption, made with constant flow pump
Absolute ethyl alcohol is pumped into glass column, until glass column bottom stops when having liquid outflow, closes valve, absolute ethyl alcohol is made to be impregnated in column
Then 1h is blown out whole liquid with air pump.This step 1 time is repeated, resin regeneration is completed.The eluting agent that the process uses
30mL (0.5 times of column volume) is only needed, organic contamination that is simple for process, generating is small, environmentally protective.
It repeats the above adsorption and desorption step twice, draws breakthrough curve.Breakthrough curve is according in different time adsorption liquid
The concentration of object is drawn.Can visually see the adsorption capacity and adsorption effect of mixed fillers from breakthrough curve.
This experiment carries out identification and with high performance liquid chromatography to phenol using gas chromatography combined with mass spectrometry to waste component
