Description
Technical field
The present invention relates to a kind of technique for treating industrial wastewater, in particular to a kind for the treatment of process of methacrylaldehyde production waste water.
Background technique
Methacrylaldehyde production is measured by propylene, air, steam (water) by technique requirement ratio respectively enters mixer, after preheating
Oxidation reactor is entered back into, catalytic oxidation is carried out at 300~400 DEG C, enters wash acid tower after cooling, is washed with water anti-
Enter absorption tower after answering the acrylic acid in gas, with the methacrylaldehyde of low-temperature cooling water absorbing reaction generation, excessive air and carbon
Oxide is vented from tower top is absorbed；Enter Analytic Tower after aqueous acrolein solution is preheated to distill, the fraction of 52~53 DEG C of collection is
Obtain finished product methacrylaldehyde.The waste water containing the methacrylaldehyde, acrylic acid etc., that is, methacrylaldehyde for distilling discharge produces waste water.
Industrial treatment methacrylaldehyde method for waste water mainly has following three kinds: activated sludge process, direct combustion method and wet type oxygen
Change method.It is acid stronger since methacrylaldehyde waste water composition is more complicated, and high organic content (COD 10000mg/L~
40000mg/L), processing is more difficult.
Although activated sludge process is to invest most to save using at most most economical conventional process, but when handling methacrylaldehyde waste water
There are two fatal defects: first is that causing microorganism that can not survive because containing in waste water largely to microorganism hazardous contaminant；
Second is that the organic pollutant of such high concentration can not be received, a large amount of water is needed to be diluted to suitable concentration, thus structures is caused to take up an area
It is very big.
Direct combustion method: because the combustible concentration in methacrylaldehyde waste water is lower, a large amount of fuel oil need to be consumed, is otherwise needed dense
Contracting pretreatment.The main organic principle of methacrylaldehyde waste water is low-boiling-point substance, and concentration pretreatment is not easy to carry out, and has very disaster in operation
Degree, therefore somewhat expensive.
Wet oxidation process: it is possible in theory, actually also there is utilization, but the methacrylaldehyde for reaching 600t/d for water gives up
For water, one-time investment is too big.
Therefore proposing that an entire technique takes up little area, one-time investment is small, the place of the low methacrylaldehyde production waste water of processing cost
Science and engineering skill, is very important.
Summary of the invention
The purpose of the present invention is to provide a kind for the treatment of process of methacrylaldehyde production waste water, which is not required to will be highly concentrated
The organic pollutant of degree dilutes, and is eliminated hazardous contaminant using improved Fenton reagent method, to meet active dirt
The condition of mud method, entire technique take up little area, and one-time investment is small, and processing cost is low.
Technical scheme is as follows: a kind for the treatment of process of methacrylaldehyde production waste water, it is characterised in that: using improvement
Fenton deep oxidation and activated sludge process combine, the control parameter of improved Fenton deep oxidation has the inlet flow-patterm to be
3.0~4.0, flocculation pH is pH after natural reaction, is 2.5~3.5, will be into the waste water of Wastewater Treated by Activated Sludge Process after the completion of flocculation
Adjust pH to 6.5~7.5.
Alkali is added in entering the intermediate pool before ESBG and handles by the present invention.
The present invention by improving the control parameter of Fenton deep oxidation, by inlet flow-patterm becomes 3.0 from 2.5~3.5~
4.0, pH is not adjusted before flocculation, is directly the pH 2.5~3.5 after natural reaction, playing flocculation in this way is organic acid iron Fe
(CiOj)n(wherein i < 5, j < 10) and ferric hydrated product (Fe(H2O)n(OH)6-n) (wherein n=0,1,2,3,4,5,6)
Joint effect waits flocculations to adjust pH again to 6.5~7.5 after the completion.
The present invention is eliminated hazardous contaminant using improved Fenton reagent method, to meet activated sludge process
Condition, entire technique take up little area, and one-time investment is small, and processing cost is low.
Detailed description of the invention
Fig. 1 is routine Fenton deep oxidation+activated sludge process process flow chart；
Fig. 2 is process flow chart of the invention.
Specific embodiment
Below by specific embodiments and the drawings, the present invention is described in detail:
From Fig. 1, Fig. 2 it is found that process flow and the process flow of routine Fenton deep oxidation+activated sludge process of the invention is big
Cause identical, the equipment of use is just the same, unlike Fenton deep oxidation control parameter.
The process flow of conventional Fenton deep oxidation+activated sludge process: the waste water come from conditioning tank, in pre-acidified pond
PH value is adjusted to 3.0 or so, according to waste water COD concentration, a certain proportion of ferrous and hydrogen peroxide, reaction one is added by sewage total amount
It fixes time (such as 2 hours), then adds Chi Lijia alkali in PAM and adjust pH value to 6.5~7.5, it is heavy that the flocculation of PAM flocculation aid is added
It forms sediment, supernatant enters consequent activities sludge section and carries out biochemical treatment.
Process flow of the invention: the waste water come from conditioning tank adjusts pH value to 3.0~4.0 in pre-acidified pond, according to
Waste water COD concentration is added a certain proportion of ferrous and hydrogen peroxide by sewage total amount, reacts certain time (such as 2 hours), then exist
PH(is generally 2.5~3.5 after natural reaction) under in flocculation basin plus PAM flocculation aid flocculation, into sedimentation basin in mud-water separation,
Supernatant enters clear water reserviors and alkali is added to adjust pH value to 6.5~7.5, carries out biochemical treatment into consequent activities sludge section.
The present invention is the treatment process that a kind of methacrylaldehyde produces waste water, it is characterised in that: uses improved Fenton depth
Oxidation and activated sludge process combine, and it is 3.0~4.0 that the control parameter of improved Fenton deep oxidation, which has inlet flow-patterm, flocculation
PH is natural reaction pH, is 2.5~3.5, adjusts pH to 6.5~7.5 after the completion of flocculation.
The present invention by improving the control parameter of Fenton deep oxidation, by inlet flow-patterm becomes 3.0 from 2.5~3.5~
4.0, pH is not adjusted before flocculation, is directly natural reaction pH 2.5~3.5, playing flocculation in this way is organic acid iron Fe
(CiOj)n(wherein i < 5, j < 10) and ferric hydrated product (Fe(H2O)n(OH)6-n) (wherein n=0,1,2,3,4,5,6)
Joint effect waits flocculations to adjust pH again to 6.5~7.5 after the completion.
Waste water is produced using conventional Fenton deep oxidation+Wastewater Treated by Activated Sludge Process methacrylaldehyde, water outlet color is reddish brown
Color, final outflow water COD are severely exceeded, and serious with mud, and the anaerobism section of biochemical unit is substantially without effect and operation a period of time
Bottom generates a large amount of bubbles in aerobic part operational process, activated sludge zoogloea is gently dissipated into there are a large amount of bronzing sludge afterwards
Bronzing, SV30 < 10%；Waste water, biochemical unit normal operation, standard water discharge, appearance are produced using present invention processing methacrylaldehyde
It is as clear as crystal.
Finally, it should be noted that above implement to be merely illustrative of the technical solution of the present invention, rather than its limitations；Although ginseng
According to previous embodiment, invention is explained in detail, those skilled in the art should understand that: it still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；And
These are modified or replaceed, the spirit and model of technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution
It encloses.
