It has and.

Analytical waste liquid 1 is a fly ash in exhaust gas discharged from various incinerators such as an municipal waste incinerator, an industrial waste incinerator, a sludge incinerator, etc., which is treated with hydrochloric acid (pH 2 or less) to dry it.
Extraction solvent 2 (eg toluene) with dioxins and PC
The liquid fraction obtained by extracting a halogenated organic compound such as B is mixed with impurities (about 1%) such as other various solvents (acetone, dichloromethane, methanol, etc.) used in the analysis. .

The condenser 110 includes a condenser main body 111 for heating the supplied analytical waste liquid 1 to evaporate and vaporize the extraction solvent 2 and the above impurities, and a condenser for cooling the vaporized extraction solvent 2 to condense and liquefy it. And 112.

The mixer 120 comprises a concentrated waste liquid 3 obtained by concentrating the analysis waste liquid 1, a hydrogen donating solvent (eg isopropanol (IPA)) 4 from the solvent supplier 130, and an alkali (eg potassium hydroxide) from the alkali supplier 140. (KO
H) etc. 5 are respectively supplied, and a stirrer 122 for stirring and mixing the concentrated waste liquid 3, the hydrogen donating solvent 4 and the alkali 5 in the storage tank 121 into a processing solution 6. There is.

The electron beam processing apparatus 150 has the processing solution 6
Is provided with a storage tank 151 for storing the processing solution 6, a stirrer 152 for stirring the processing solution 6 in the storage tank 151, and an electron beam irradiation device 153 for irradiating the processing solution 6 in the storage tank 151 with an electron beam 9.

The distillation purifier 180 is the solid-liquid separator 16 described above.
In the distillation column 181, the detoxification solution 8 separated by 0 is heated and distilled for purification, the hydrogen donating solvent 4 fractionally distilled in the distillation column 181 is condensed and liquefied, and the distillation column 181 is used.

And a feed pump 184, which is a feeding means for feeding to 0.

In FIG. 1, 8b is a high boiling point component, 191
193 are valves, and 194 are three-way valves.

<Processing Method> Next, a processing method using the processing apparatus 100 will be described.

<< Concentration Step >> The analytical waste liquid 1 is fed to the condenser main body 111 of the condenser 110 and heated to vaporize the extraction solvent 2 (for example, toluene) to such an extent that the fluidity can be maintained (the total amount of Concentrated waste liquid 3 is produced.
The extraction solvent 2 that has been heated and vaporized is cooled and liquefied in the condenser 112, and is recovered and reused or discarded.

<< Mixing Step >> Next, the hydrogen donating solvent 4 is introduced from the solvent supplier 130 into the storage tank 121 of the mixer 120.
(For example, IPA) is supplied in a predetermined amount, and while operating the stirrer 122, the storage tank 121 is supplied from the alkali supplier 140.
After a predetermined amount of alkali 5 (for example, KOH) is supplied to dissolve the alkali 5 in the hydrogen donating solvent 4, the valve 191 is opened and the concentrated waste liquid 3 is stored in the storage tank 1.
21 to prepare the processing solution 6.

The amount of the alkali 5 with respect to the hydrogen donating solvent 4 in the treatment solution 6 is preferably in the range of 0.1 wt% to the saturation amount, and particularly preferably 1 to 10 wt%. Because, if it is less than 0.1 wt%, the detoxification treatment reaction described below hardly occurs, and if it is less than 1 wt%, the efficiency of the detoxification treatment reaction described below deteriorates. This is because 5 becomes difficult to dissolve in the hydrogen donating solvent 4, and when the amount exceeds the saturation amount, the alkali 5 is wasted.

The ratio of the concentrated waste liquid 3 to the hydrogen donating solvent 4 and the alkali 5 in the treatment solution 6 is 20%.
It is preferably less than 5%, particularly preferably 5% or less. This is because if it is 20% or more, the detoxification treatment reaction described below does not sufficiently occur, and if it is 5% or less, the halogenated organic compound can be reliably detoxified.

<< Electron Beam Treatment Step >> Next, the valve 192 is opened to feed the treatment solution 6 into the storage tank 151 of the electron beam treatment apparatus 150, and the stirrer 152 is operated to scratch the treatment solution 6. When the treatment solution 6 is irradiated with the electron beam 9 from the electron beam irradiation device 153 while being mixed (500 kGy or less, preferably 300 kGy or less), the halogenated organic compound (for example, dioxins) in the treatment solution 6 becomes a halogen atom (for example, (Chlorine atom) is excited and activated, and reacts with the alkali 5 in the treatment solution 6 to form a salt (for example, potassium chloride (KCl)) to be deposited as a solid substance 7, while the position where the halogen atom is released The hydrogen atoms of the hydrogen donating solvent 4 are donated to the detoxifying agent.

<< Solid-Liquid Separation Step >> Subsequently, the solid-liquid separator 16
0 and the feed pump 170 are switched so that the three-way valve 194 is switched to operate the feed pump 170 and the valve 193 is opened, so that the solid substance 7 and the detoxifying solution 8 in the storage tank 151 are opened. Are sent to the solid-liquid separator 160 for solid-liquid separation, and the solid matter 7 is disposed of.

<< First Recycling Step >> On the other hand, the detoxifying solution 8 which has been solid-liquid separated is sent as a mixed solution of the hydrogen donating solvent 4 and the alkali 5 into the reservoir 121 of the mixer 120. Will be sent for reuse.

Hereinafter, by repeating the above-mentioned steps, the detoxifying process of the analysis waste liquid 1 can be continuously performed.

Here, most of the detoxification solution 8 is composed of the hydrogen donating solvent 4 and the alkali 5, but in addition, it is produced by the extraction solvent 2, the dehalogenated organic compound, and the electron beam irradiation. Various impurities such as various by-products (condensates) are mixed. Therefore, the detoxifying solution 8
When the above is repeatedly reused, the amount of the above impurities in the detoxification treatment solution 8 gradually increases, which causes a reduction in the capability of the above-described detoxification treatment by electron beam irradiation.

<< Second Reuse Step >> Then, the above steps are repeated a plurality of times, and when the amount of impurities in the detoxification solution 8 becomes 20% or more (preferably more than 5%), solid-liquid separation is performed. The three-way valve 194 is switched so as to establish communication between the vessel 160 and the distillation / purification apparatus 180, and the detoxified solution 8 that has been subjected to solid-liquid separation is fed into the distillation column 181 of the distillation / purification apparatus 180, heated and distilled. By doing so, the fraction of the hydrogen donating solvent 4 is isolated, cooled in the condenser 182 to be condensed and liquefied, and then fed by the feed pump 184 to the solvent feeder 130 for reuse.

On the other hand, the low boiling point component 8a having a boiling point lower than that of the hydrogen donating solvent 4 is cooled and condensed by the condenser 183,
The high-boiling component 8b having a boiling point higher than that of the hydrogen-donating solvent 4 (for example, toluene, dehalogenated organic compound or condensate) is recovered and discarded, and the hydrogen-donating solvent 4 is regenerated and recovered. Later, it is extracted from the distillation column 181 and disposed of.

Therefore, according to the present embodiment, the analytical waste liquid 1 containing the halogenated organic compound can be easily detoxified.

Further, since the detoxifying solution 8 from which the solid material 7 has been separated is reused, the cost for the treatment can be reduced.

Furthermore, the detoxifying solution 8 reused repeatedly was used.
Since the hydrogen donating solvent 4 is isolated and recovered by distillation purification, it is possible to prevent a reduction in the detoxification treatment capacity due to impurities that increase with repeated reuse.
