Abstract
The present invention relates to a kind of triethylamine method of wastewater treatment, comprise the following steps: triethylamine waste water is continuously pumped into waste water treatment tank by a.；B. copperas solution and the inorganic agent of hydrogen peroxide residual liquid composition it are passed through；C. adjust sewage PH value, control to carry out sewage disposal reaction with triethylamine wastewater volume than the amount for 0.29:1 according to inorganic agent at 3.5 ~ 4.0d.；E. the control response time is 6 hours, and this oxidation digestion process is for persistently to carry out process, and the wastewater flow rate of triethylamine continued into waste water treatment tank according to 6 hours, and inorganic agent is also for continuing into, until COD ＜ 7140 in waste water.It is an advantage of the current invention that: utilizing hydrogen peroxide residual liquid to process the sewage of triethylamine with ferrous sulfate, make hydrogen peroxide residual liquid turn waste into wealth, processing cost is low, achieves beyond thought result；COD clears up rate and is up to 80%, reduces the difficulty of subsequent treatment；Water color after process is limpid, and mud generation amount is few.
Description
Technical field
The invention belongs to high COD sewage processing method, relate to a kind of triethylamine method of wastewater treatment.
Background technology
The waste water COD produced in triethylamine remanufacture is up to 40000, and general employing Fenton is diluted raw after processing
Change processing method, but this common Fenton technology not only cost be high, and clear up COD and lead the highest, also with substantial amounts of once
Water dilutes so that subsequent biochemical treating capacity greatly adds.In Hydrogen Peroxide Production, containing dioxygen in the residual liquid of generation
Water 2 ~ 2.8%, contains some Organic substances simultaneously, and COD is up to 15000, it is difficult to process.
Summary of the invention:
The purpose of the present invention is contemplated to overcome existing triethylamine production wastewater treatment cost high and clear up COD lead the highest
Shortcoming, it is provided that a kind of triethylamine method of wastewater treatment.
Technical scheme is as follows:
A kind of triethylamine method of wastewater treatment, comprises the following steps:
A. triethylamine waste water is continuously pumped into waste water treatment tank, opens air stirring；
B. be passed through the copperas solution that concentration is 3.2-4.8% and the hydrogen peroxide residual liquid that hydrogen peroxide content is 2 ~ 2.8% composition
Inorganic agent, wherein the use volume ratio of copperas solution and hydrogen peroxide residual liquid is 0.079: 1；
C. adjust sewage PH value, control 3.5 ~ 4.0
D. sewage disposal reaction is carried out according to inorganic agent with the amount that triethylamine wastewater volume ratio is 0.29: 1；
E. the control response time is 6 hours, and this oxidation digestion process is for persistently to carry out process, and the wastewater flow rate of triethylamine is little according to 6
Time continue into waste water treatment tank, inorganic agent also for continuing into, until waste water in COD ＜ 7140.
The present invention compared with existing sewage water treatment method, have an advantage in that:
1, utilize hydrogen peroxide residual liquid and the sewage of ferrous sulfate process triethylamine of hydrogen peroxide 2 ~ 2.8% content, make hydrogen peroxide residual liquid
Turning waste into wealth, processing cost is low, achieves beyond thought result；
2, COD clears up rate and is up to 80%, reduces the difficulty of subsequent treatment；
3, the water color after processing is limpid, and mud generation amount is few.
Accompanying drawing illustrates:
Fig. 1 is that the present invention provides waste water processes figure.
Example 1
Triethylamine sewage 150m3It is continuously pumped into 250 m3Waste water treatment tank, recording COD is 40000.By ferrous sulfate 120kg, molten
In 3m3In water, hydrogen peroxide residual liquid 40m3, record hydrogen peroxide residual liquid hydrogen peroxide content be 2%, COD be 15000, control reaction
Time is 6 hours, uniformly instills continuous to copperas solution and hydrogen peroxide residual liquid 6 hours in sewage, clears up reacted obtaining
To sewage 190m3, COD is 6830.
Hydrogen peroxide residual liquid is pumped into and tangentially enters bottom sewage treatment tank；Separately set stirring air and enter sewage disposal
Groove is identical with hydrogen peroxide residual liquid approach axis；Hydrogen peroxide, air enter the direction of sewage treatment tank, are the tangent line for the treatment of trough
Direction, at trench bottom just to direction.
Example 2
Triethylamine sewage 150m3It is continuously pumped into 250 m3Waste water treatment tank, recording COD is 41000, by ferrous sulfate 135kg, molten
In 3.1m3In water, hydrogen peroxide residual liquid 41m3, record hydrogen peroxide content in hydrogen peroxide residual liquid be 2.5%, COD be 15000, control
Response time processed is 6 hours, uniformly instilled continuous to copperas solution and hydrogen peroxide residual liquid 6 hours in sewage, clears up reaction
After obtain sewage 191m3, COD is 6945.
Example 3
Triethylamine sewage 150m3It is continuously pumped into 250 m3Waste water treatment tank, recording COD is 42000, by ferrous sulfate 150kg, molten
In 3.2m3In water, hydrogen peroxide residual liquid 42m3, record hydrogen peroxide content in hydrogen peroxide residual liquid be 2.8%, COD be 15000, control
Response time processed is 6 hours, uniformly instilled continuous to copperas solution and hydrogen peroxide residual liquid 6 hours in sewage, clears up reaction
After obtain sewage 192m3, COD is 7140.
The data statistic of three groups of examples is as follows:
