For example, in the catalytic cracking method using a catalyst such as manganese dioxide, the
Therefore, it is necessary to adjust the flow rate of wastewater. However, it is often difficult to change the amount of wastewater due to production processes, etc., so in practice it is necessary to have some margin in the capacity of wastewater treatment equipment.

スト高となる。In addition, regarding the reductive decomposition method using a reducing agent, it is possible to respond by adjusting the amount of reducing agent used depending on the hydrogen peroxide concentration in the wastewater. Although it is an economically advantageous method if an inexpensive reducing agent such as salt is available,
If 1'G is not blessed with such locational conditions, the cost will be high.

Inorganic porous particles such as alumina, silica-alumina, and titania are preferred, and silica or alumina is more preferred. These particles also contain cobalt, iron, nickel,
Those containing a small amount of transition metal compounds such as manganese have better ability to decompose hydrogen peroxide. Non-conductive porous particles have a specific surface area of On? /g or more, preferably 5

Particles of metal oxides such as ferrite, metals such as stainless steel are preferred, and carbonaceous materials such as coke and activated carbon are more preferred. The conductive particles do not necessarily have to be porous, but if they have adsorption performance similar to non-conductive porous materials, the ability to decompose hydrogen peroxide will be further improved. Furthermore, if a small amount of a transition metal compound such as that mentioned above is contained, further improvement can be achieved. Further, the particle size is preferably in the same range as the non-conductive porous particles.

層は１層であっても複数層であっても差し支えない。A packed layer is formed by mixing conductive particles and non-conductive porous particles. It is necessary to mix the non-conductive porous particles at a mixing ratio that prevents the conductive particles from coming into contact with each other and forming one large conductor, but if there are too many non-conductive porous particles, Since the current efficiency decreases, conductive particles 1$
It is desirable that the non-conductive porous particles be used in a range of 0.1 to 10 parts by volume, preferably 0.5 to 2 parts by volume, per part of ff. The filling layer may be one layer or multiple layers.
充填層は一対の主電極間の対向空間に設ける。The filling layer is provided in the opposing space between the pair of main electrodes.

It is desirable that one electrode be in contact with one end of the filling layer.Furthermore, in this case, if the (-) pole is a pole in contact with one end of the filling layer, not only can wear of the electrode be reduced, but also
Current efficiency is also improved.
主電極の材質は（＋）極側は耐食性に優れる炭素電極が
好ましいが、（＝）極側は金属電極であ−。The material of the main electrode is preferably a carbon electrode with excellent corrosion resistance on the (+) side, but a metal electrode on the (=) side.

Electrolysis occurs and hydrogen peroxide is decomposed and removed. Direct current is preferable since the hydrogen peroxide removal efficiency is poor relative to the power consumption when alternating current is used. Moreover, if the wastewater is made to flow continuously, an increase in the throughput can be achieved. In addition,
If the electrical conductivity of the wastewater is low, it is advisable to add inorganic salts or wastewater containing them or seawater.

Furthermore, since the non-conductive porous particles are porous and have adsorption performance, they are thought to increase the residence time of hydrogen peroxide and increase the decomposition rate of hydrogen peroxide. Then, the catalytic decomposition of hydrogen peroxide by non-conductive porous particles, the direct decomposition of hydrogen peroxide by electrolysis, or the reduction by the nascent hydrogen gas generated by electrolysis, etc. It is thought that this contributes to the decomposition of Furthermore, it is believed that by incorporating a transition metal compound into conductive particles or non-conductive porous particles, effects such as catalytic decomposition other than electrolysis occur.
