The disclosed complex odor treatment system includes a complex odor supply device and a catalytic oxidation water supply device, wherein the complex odor supplied by the complex odor supply device is contacted with the catalytic oxidation water supplied by the catalytic oxidation water supply device to remove the complex odor do.
Description
A complex odor treatment system is disclosed. More particularly, a complex odor treatment system using catalytic oxidation water is disclosed.
In a place such as a sewage treatment plant, a sewage treatment plant, a food processing facility, an animal husbandry facility, etc., various organic or inorganic gases are generated and a complex odor is generally generated. Since the malodor is strong in complexity, There are difficult features.
In view of these characteristics, there are various methods for removing organic or inorganic odor gas. First, there are a plurality of nozzles in the deodorization tower, and water is sprayed from the odor-containing gas introduced into the deodorization tower to remove the offensive odor. Second, there is a method (an activated carbon adsorption method) in which an adsorbent layer such as activated carbon, silica gel and zeolite is disposed in a deodorization tower to adsorb odorous substances. Third, there is a method (microbial contact method) of disposing a specific microbial layer in the deodorization tower so that the microbes decompose the odor generating substances. Fourth, there is a washing and deodorizing tower, which is a general odor treatment facility that neutralizes odor components by bringing chemical liquid such as sulfuric acid or caustic soda into contact with odor components to cause a chemical reaction to remove odors.
However, in the case of the water washing method and the washing and deodorizing tower, there is an effect when the malodor component is well absorbed in water or a chemical solution, but a problem in that the treatment effect is unsatisfactory in the compound odor in which the malodor component is not easily absorbed in water or a chemical solution have.
The complex odor gas composed of an acid component, a basic component and a neutral component is usually cleaned by causing a neutralization reaction with "acid and alkali". Conventional deodorization towers using a neutralization reaction between the complex odor gas and " acid and alkali " as described above include two or more deodorization towers, that is, an acid washing tower and an alkali washing tower connected in series or in parallel.
On the other hand, basic odor components such as ammonia and amine are treated in an acid washing tower using sulfuric acid, and acidic odor components such as methyl mercaptan and hydrogen sulfide in residual odor are treated in an alkali washing tower using caustic soda, There have been attempts to treat neutral odor components such as malodorous acetaldehyde in biosystems such as biofilm tops using microorganisms. However, such attempts have shown that microbial growth deterioration occurs frequently in the biosystem due to caustic soda scattered in the alkali washing column, and the growth environment of specific microorganisms reacting only to specific odor components and the temperature, pH and humidity And the technical difficulties of system maintenance and the like. Therefore, there is a problem that the complex odor can not be satisfactorily treated.
On the other hand, the deodorization tower for removing the complex odor has been developed as the first generation deodorization tower and the second generation deodorization tower.
First, the first-generation deodorization tower is designed to contain acidic odor components such as hydrogen sulfide, methyl mercaptan, and sulfur dioxide contained in the exhaust gas, basic odor components such as ammonia and amine, and neutral odor components such as acetaldehyde A plurality of separate deodorization towers connected in series or in parallel to each other in which an acid washing liquid and an alkali washing liquid are respectively circulated in a sewage treatment plant, a manure treatment plant, a food processing facility, an animal husbandry facility, Can be independently removed by reacting with the respective cleaning liquids. However, the first-generation deodorization tower is complicated in structure, has a complicated construction, has a problem in that the deodorization speed of the complex odor gas is not quick, and the deodorization power is limited. Also, have.
The second generation deodorization tower may circulate separately the acid cleaning solution and the alkali cleaning solution in a single deodorization tower instead of two or more interconnected deodorization towers to separately chemically react with the individual components of the complex odor to remove the entire complex odor . However, the second-generation deodorization tower has not completely solved the problems of the first-generation deodorization tower, and has a complicated structure due to the structure installed for the purpose of preventing the generation of neutralized salt in the washing process.

The radical initiator may be used in the form of an aqueous solution.
The concentration of the radical initiator in the aqueous solution may be 10 to 100 ppm by weight.
In the catalytic oxidation water production apparatus, the radical initiator (for example, NaOCl) may contact with the functional catalyst to generate radicals through the following reaction.
≪ Before contacting with functional catalyst >
Before NaOCl comes into contact with the functional catalyst, the following reaction takes place in an aqueous solution state.
NaOCl + H 2 O → NaOH + HOCl (1)
NaOCl - > Na + + OCl - (2)
Since NaOCl itself is alkaline, OCl - is stable, but NaOCl is diluted by mixing with water before contact with the functional catalyst, so that it has a neutral pH and is converted to more stable HOCl. Specifically, when sodium hypochlorite (NaOCl) is dissolved in water, the sodium hypochlorite is decomposed into sodium hydroxide (NaOH) and hypochlorous acid (HOCl) to become alkaline.
≪ After contacting with the functional catalyst &
The above reaction (1) is extremely slow and does not easily proceed with a forward reaction in a normal state, but the functional catalyst remarkably promotes the reaction of the reaction (1).
When HOCl is contacted with the functional catalyst, the following reaction occurs.
HOCl → HCl + [O] (3), where [O] represents an oxygen radical.
That is, hypochlorous acid (HOCl) is decomposed to generate oxygen radicals, which exhibit a strong oxidizing action. The catalytic oxidation water thus produced has a strong oxidizing power of up to 300 times that of general chlorinated compounds. Therefore, the oxygen radicals and the hydroxyl radicals contained in the catalytic oxidation water chemically react with the complex odor, and the oxidation reactivity of the radicals is extremely excellent.
When the radical initiator is chlorine, the chlorine reacts with the functional catalyst as described below.
Cl 2 + H 2 O → HOCl + HCl (4)
HOCl? HCl + [O] (5)
HOCl ↔ H + + OCl - or Cl - + [OH] (6), where [OH] represents the hydroxyl radical.

3) Treatment of methyl mercaptan (CH 3 SH)
CH 3 SH + 3 [O] -> CH 3 SO 3 H, and methylsulfonic acid (CH 3 SO 3 H) are also dissolved in water to eliminate the odor.
4) Treatment of methyl sulfide (CH 3 SCH 3 )
CH 3 SCH 3 + [O] → (CH 3 ) 2 SO, dimethylsulfoxide ((CH 3 ) 2 SO) reacts continuously with the oxygen radical as follows.
(CH 3 ) 2 SO + 2 [O] → (CH 3 ) 2 SO 3 , and dimethylsulfonic acid (CH 3 SO 3 H) are also dissolved in water to eliminate the odor.
5) Treatment of methyl disulfide ((CH 3 ) 2 S 2 )
(CH 3 ) 2 S 2 + H 2 O → CH 3 SH + CH 3 SOH and methanesulfinic acid (CH 3 SOH) are also dissolved in water to eliminate the smell.
CH 3 SH + 3 [O]? CH 3 SO 3 H, as described above, methylsulfonic acid (CH 3 SO 3 H) is also dissolved in water and the odor disappears.
When the catalytic oxidation water is used as a cleaning liquid for the complex odor treatment system, the radicals contained in the catalytic oxidation water chemically react with neutral odor components at an equivalent ratio, and basic odor components and acid malodor components are also mixed with the catalytic oxidation water It can be simply increased and treated at the equivalence ratio.

Characterized in that the reactor is connected in series to a connecting duct or a final exhaust stack of a previously installed odor treatment system to treat the complex odor component
Complex odor treatment system.
Wherein the radical initiator is used in the form of an aqueous solution, wherein the concentration of the radical initiator in the aqueous solution is from 10 to 100 ppm by weight.
