Disclosed is a method of simultaneously processing fly ash and COPR, which can treat the fly ash and COPR harmlessly during the landfilling process through biochemical and engineering measures. The method includes: transferring the fly ash and COPR to the yard; laying an impervious layer inside the yard; laying a diversion material at a bottom of the yard; laying a mixture layer on the diversion material, where the mixture layer contains a biogas residue, a waste carbon source, ferrous sulfate, a nutritional additive, the waste incineration fly ash and COPR; placing an internal-electrolysis ceramsite layer on the mixture layer; injecting a carbon source solution from an upper portion of the yard and collecting a leachate to a collection device through the diversion material irregularly during the operation; and recirculating the leachate to a top of the yard for spray reinjection.

A water treatment device includes, between at least two flat sheet-shaped grounded electrodes vertically disposed so as to be parallel to each other, a sheet-shaped high-voltage electrode having two edges opposing the respective grounded electrodes. The sheet-shaped high-voltage electrode is supported by a plurality of support members, and thus deformation of the high-voltage electrode in an up/down direction and a horizontal direction is suppressed, and the distance between each edge of the high-voltage electrode and the corresponding grounded electrode, i.e., an electric discharge gap length, can be kept even. Accordingly, uniform electric discharge can be maintained between the high-voltage electrode and the grounded electrode, whereby highly efficient water treatment can be realized.
