Definitions
- the present invention relates to an anaerobic treatment method and treatment apparatus for terephthalic acid-containing wastewater, and more particularly to a method and apparatus for efficiently decomposing and removing hardly decomposable terephthalic acid in wastewater by anaerobic treatment.
- Waste water from the polyethylene terephthalate manufacturing process usually contains terephthalic acid, p-toluic acid, benzoic acid, and the like.
- nutrient salts and trace metals are required in the anaerobic treatment system for cell synthesis.
- about 1.5% of sulfate ion is required as SO 4 2 ⁇ with respect to COD Cr in the waste water.
- Chemical wastewater and electronic industrial wastewater contain almost no components necessary for cell synthesis.
- mineral components are added.
- Sulfate ions are decomposed by sulfate-reducing bacteria in the methane fermenter to generate hydrogen sulfide gas and increase the load of exhaust gas treatment. Since hydrogen sulfide inhibits methane fermentation and reduces the processing efficiency, sulfate ions are added so as not to exceed the concentration required for cell synthesis.
- Terephthalic acid and p-toluic acid are hardly decomposable for anaerobic treatment.
- Wastewater containing hardly decomposable organic substances that are difficult to decompose by anaerobic treatment is aerobically treated.
- Anaerobic treatment has the advantages of being capable of high load treatment, lower running costs, and less CO 2 emissions than aerobic treatment. Therefore, it is desired to anaerobically treat waste water containing terephthalic acid or p-toluic acid.
- Patent Document 1 describes a method of performing anaerobic treatment after treating terephthalic acid-containing wastewater with ozone in order to increase the decomposition efficiency of terephthalic acid in anaerobic treatment.
- this method has high processing efficiency, the apparatus for ozone treatment is complicated and the processing cost is high.
- Patent Document 2 in order to prevent granulated sludge from floating and flowing out, an iron salt and a sulfate ion source are added to the waste water, and iron sulfide (FeS) is generated by a reaction between the iron salt and the sulfate ion.
- FeS iron sulfide
- An anaerobic wastewater treatment method is described in which a sludge cavity is filled with iron sulfide. In this method, since the added sulfate ion source is precipitated as FeS, the sulfate ion concentration in the anaerobic treatment tank does not increase.
- the present invention highly efficiently decomposes and removes terephthalic acid by subjecting hardly-decomposable terephthalic acid-containing wastewater to anaerobic treatment efficiently at low cost without requiring complicated equipment and complicated operations. It is an object of the present invention to provide a method and an apparatus capable of performing the above.
- the present inventors have added a predetermined amount of sulfate radical (SO 4 2 ⁇ ) in anaerobic treatment of waste water containing terephthalic acid, and decomposed terephthalic acid in the anaerobic treatment. It has been found that the efficiency is dramatically improved.

Can be efficiently decomposed and removed by anaerobic treatment to obtain high-quality treated water (claims 1 and 7).
- SO 4 2 ⁇ sulfate radicals
- the present invention can be implemented easily and at low cost with a simple apparatus without requiring complicated apparatus facilities and complicated operations.
- the sulfate radical is preferably added in an amount of 10% by mass or more with respect to terephthalic acid in the waste water, and the content in the waste water is 60 to 400 mg / L. 9).
- the present invention is suitable for treating terephthalic acid-containing wastewater containing terephthalic acid in an amount of 50 to 2000 mg / L and further containing paratoluic acid (claims 4, 5, 10, and 11).
- a predetermined amount of sulfate radical is added to the wastewater. It is possible to promote the sulfuric acid reduction reaction by adding an excessive amount of sulfate radicals to the wastewater than the amount necessary for the cell synthesis. As a result, the hydrogen partial pressure is lowered, and as a result, the inside of the anaerobic treatment system is reduced to promote the methane formation reaction, and it is considered that the hardly decomposable terephthalic acid is decomposed and removed.
- the raw water to be treated in the present invention is effluent containing terephthalic acid, and includes terephthalic acid-containing effluent discharged from various industrial fields such as the chemical industry and the electronics industry, such as polyethylene terephthalate manufacturing process effluent. It is done.

- the agent for adding the sulfate radical is preferably added as an aqueous solution having a SO 4 2 ⁇ concentration of 5 to 30% by mass.
- the sulfate radical has an SO 4 2 ⁇ concentration in the waste water of preferably 30 to 400 mg / L, more preferably 60 to 400 mg / L, more preferably 50 to 200 mg / L, and particularly preferably 70 to 200 mg / L. It is preferable to be added to.
- the sulfate radical is preferably added to the wastewater at a ratio of 10% by mass or more, particularly 15 to 30% by mass with respect to the terephthalic acid in the wastewater. If the content of sulfate radicals relative to terephthalic acid in the wastewater is too small, the decomposition efficiency of terephthalic acid may not be sufficiently increased.
- the sulfate radical is added to the wastewater at a rate of 10% by mass or more, especially 15 to 30% by mass, based on the total amount of terephthalic acid and paratoluic acid in the wastewater. It is preferable.
- the sulfate radical is added to the waste water so that the sulfate ion concentration in the treated water obtained by anaerobic treatment is 5 to 200 mg / L, preferably 10 to 20 mg / L. If the sulfate ion concentration is less than 5 mg / L in the anaerobic treated water, the sulfate addition effect according to the present invention cannot be sufficiently obtained. If the sulfate ion concentration of the anaerobic treated water is excessively high, the amount of hydrogen sulfide gas generated increases, the water quality of the anaerobic treated water itself deteriorates, and the load on the subsequent treatment process increases.
- the anaerobic treatment method may be a one-phase system in which the acid production process by acid-producing bacteria and the methane fermentation process by methane-producing bacteria are performed in the same tank, or a two-phase system in which these are performed in separate tanks. Also good.

- UASB method or EGSB method capable of high load treatment is preferable.
- the sulfate radical may be added to either the anaerobic treatment tank or the raw water flowing into the anaerobic treatment tank.
- sulfuric acid is added as the sulfate radical
- the pH is lowered by the addition of sulfuric acid. Therefore, when a pH adjusting tank is provided, it is preferably added at the preceding stage.
- the location of sulfate radical addition is selected according to the amount of material to be treated in the waste water.
- a sulfate group When there are many easily decomposable substances in the waste water, it is preferable to add a sulfate group at a position close to the methane fermentation tank.
- a sulfate group in the former stage for example, an acid production tank. This is because the decomposition promoting effect of terephthalic acid and p-toluic acid is reduced if the sulfate radical is consumed during the decomposition of the easily decomposable substance.
- the conditions for anaerobic treatment vary depending on the method employed, but the pH is 6 to 8, the temperature is 25 to 39 ° C., the residence time is 4 hours to 3 days, the anaerobic sludge concentration is 10,000 to 40,000 mg-VSS / L, and the load is 1. ⁇ 15 kg-BOD / m 3 ⁇ day, CODcr load is preferably 2 to 30 kg-CODcr / m 3 ⁇ day.
- Anaerobic treated water can be subjected to aerobic treatment such as activated sludge treatment and other post-treatments in order to decompose the remaining organic matter.
- terephthalic acid which is hardly decomposable by anaerobic treatment can be efficiently decomposed and removed by anaerobic treatment. Even when anaerobic treatment is performed after anaerobic treatment of the waste water, the load of the anaerobic treatment is reduced, and the processing cost is reduced.
- the hydrogen sulfide gas may be subjected to biological desulfurization treatment.
- biological desulfurization treatment if the concentration of hydrogen sulfide in the gas to be treated fluctuates, sulfur-oxidizing bacteria do not grow stably and the treatment becomes unstable.
- the concentration of hydrogen sulfide in the exhaust gas is stabilized by adding a predetermined amount of sulfate radical to the waste water, so that the biological desulfurization treatment is stably performed.
