Description of the Related Art In recent years, deterioration of the water quality environment such as eutrophication and pollution of water in lakes and reservoirs has become a problem. For example, musty odor substances (diosmin, 2-methylisoborneol) produced by phytoplankton, and Carcinogens such as trihalomethane have been introduced into the water supply. For this reason, it has become common to install a water purification device using activated carbon as a filter medium even at home.

生時に活性炭に消耗があることなどが原因である。However, activated carbon, which is a filter medium, cannot be escaped from the fact that the filtration performance is deteriorated due to so-called clogging. However, in the water purifier provided for household use, activated carbon is It was disposable and never reused. Of course, it is common to industrially recycle activated carbon, but using this technology to regenerate activated carbon for household water purification equipment requires high initial costs, large equipment, and activated carbon during regeneration. The cause is that there is exhaustion.

う欠点がある。By the way, it is common to regenerate the activated carbon used for water treatment by decomposing or oxidizing the adsorbate to remove it. As a method of oxidizing and decomposing, A is an oxidizing gas (O 2 , H at high temperature). Pyrolysis by 2 O, CO 2 ) B Oxidative decomposition by microorganisms C Oxidation by using an oxidizing agent (H 2 O 2 , O 3 ), and the method of A is generally adopted.
Since the treatment is carried out at a high temperature of up to 1000 ° C., there are disadvantages that the apparatus becomes large and activated carbon is consumed greatly. In method B, when dissolved oxygen decreases, anaerobic microorganisms increase,
Sulfides may appear in the effluent if there is clogging or if there are sulfate groups in the effluent. Further, if the dissolved oxygen is sufficiently present in the inflowing water, aerobic microorganisms increase, causing clogging, which makes it difficult to control the microorganisms.

Even if the recovery of the adsorption capacity of 71% was obtained in the first regeneration, it was 50 in each of the second and third regenerations.
%, Only 20% recovery is obtained, and there is a drawback that the adsorption capacity decreases as the number of times of regeneration increases.

できる。According to the present invention, by heating the activated carbon that adsorbs a substance corresponding to the pore size to a temperature that depends on the adsorbed substance, it is possible to perform thermal regeneration while minimizing the consumption of the activated carbon. That is, the adsorption capacity of a substance by activated carbon largely depends on its pore distribution, and the adsorbed substance is likely to be trapped in the pores having a diameter substantially the same as its molecular diameter. For example, musty substances (diosmin, 2-methylisoborneol)
In addition, trihalomethane (chloroform, bromodichloromethane, etc.) has a molecular diameter of 4 to 6 angstroms, and is often adsorbed by activated carbon having pores of this size. Moreover, since the molecular weight of humic substances and fulvic substances of organic substances is several thousand to several hundred thousand, it is estimated that the molecular diameter is several tens to several hundreds angstroms, and in fact, many pores with diameters of 30 to 300 angstroms are distributed. It is well adsorbed by activated carbon. Therefore, by combining the activated carbon layers having these pore sizes, the above substances can be selectively and efficiently adsorbed and removed.

It was found that desorption occurs at 100 ° C or higher. Moreover, when the thermal characteristics of musty odor substances were examined by differential thermogravimetric analysis,
Sublimability is observed at 120 ° C., thermal decomposition occurs at 120 to 135 ° C., and regeneration at 130 to 200 ° C. is possible. 50 for humic and fulvic substances
It can be regenerated at 0 to 800 ° C. Furthermore, although organic substances such as iron rust and scale are not regenerated at low temperatures, such organic substances can be removed by a filter. Therefore,
As described above, by heating the activated carbon layer that selectively removes each substance at a temperature corresponding to the substance to be adsorbed, it is possible to perform thermal regeneration in a state in which the consumption of activated carbon is minimized. .
