Description
Technical field
The present invention relates to a kind of isobutylene oxidation methods to produce methyl methacrylate (MMA) producing wastewater treatment, belongs to
In technical field of waste water processing.
Background technique
Methyl methacrylate (MMA) is a kind of important Organic Chemicals and chemical products, current whole world MMA mainstream
Production process route mainly have Acetone cyanohydrin method, isobutylene oxidation method, ethenecarbonyl method etc., the feed hydrogen of Acetone cyanohydrin method
Cyanic acid toxicity is big, and sulfuric acid is used in technique, and processing spent acid spends very big investment, to safe and environment-friendly more demanding；Ethylene carbonyl
The high production cost of base method, competitiveness can be had by needing to combine integrated produce of progress with ethylene production；Isobutylene oxidation
One kind owned by France in Green Chemistry, relative to both the above, isobutylene oxidation method raw material is sufficient, avoids using violent in toxicity, to ring
The influence in border is smaller；Therefore isobutylene oxidation method production methyl methacrylate (MMA) is the method for current domestic most prospect.
Using isobutene as raw material, MMA is synthesized by catalysis oxidation -ester method, this technique is divided into three-step approach and two step method, and three
Footwork is that isobutylene oxidation generates methacrolein (MAL), and MAL oxidation generates methacrylic acid (MAA), last MAA esterification life
At MMA；Two step method is to be combined into one the MAL oxidative esterification process of generation, and a step oxidative esterification generates MMA.Isobutylene oxidation
The dominant mechanism for generating MMA is: adsorbing c h bond fracture on a catalyst first, sloughs a hydrogen atom and become π-allyl
Intermediate, then by the lattice oxygen oxidation in catalyst at MAL.Other than main reaction, along with parallel or side reaction, it can generate
Acid, aldehyde, CO, CO2, in addition isobutene acetone, acetaldehyde, the by-products such as acetic acid can be also generated with water.According to process control parameter
Difference, isobutylene oxidation method produce 5.28-10% containing acetic acid, propionic acid 0.1-0.71%, third in methyl methacrylate (MMA) waste water
Olefin(e) acid 0.7-1.1%, methacrylic acid 0.21-0.48%, formaldehyde 0.8-1.2%, other organic matters 0-2%.Wherein acetic acid content compared with
Height, so that the excessively high growth to inhibit methanogen in anaerobic reaction of waste water acescency, and other organic matters also can be right
Anaerobic species have adverse effect on, so that anaerobism volumetric loading can not improve, anaerobic biochemical reaction low efficiency.
Isobutylene oxidation method produces the waste water of methyl methacrylate (MMA), and waste water quality is as follows: COD 80000-
100000mg/L, pH value 2.0-3.0.Because containing the organic matters such as a large amount of aldehydes in waste water, this substance is at normal temperatures and pressures
The polymer of itself is formed, this polymer is translucent or the solid or flock of white, aldehydes autopolymer can largely exist
In in anaerobic reactor, cotton-shaped aldehydes autopolymer is attached on anaerobic sludge, greatly hinders the progress of anaerobic biochemical reaction,
Biochemical sludge is even poisoned, can be also enriched in biochemical system, finally make wastewater biochemical systemic breakdown.
Isobutylene oxidation method production methyl methacrylate (MMA) belongs to Fine Chemical, and production process is simple
Chemical industry synthesis, reaction step is short, and raw material is single；The waste water composition that it is produced is single, lacks nitrogen, phosphorus etc. that microorganism growth needs
The growth factors such as inorganic salts, microelement；If the other elements that no additional biological growth needs, the biochemical treatment system of waste water are easy
There is phenomena such as sludge crushing, disintegration, expansion, loss, final wastewater biochemical system is difficult to efficient, stable operation.
Summary of the invention
The existing processing technique of methyl methacrylate (MMA) waste water is produced for isobutylene oxidation method in background above technology
Deficiency, the present invention provides a kind of isobutylene oxidation method production methyl methacrylate (MMA) wastewater treatment method.The present invention is useless
