More specifically, the biological rotating disk reaction tank 400 is communicated with the micro-electrolysis reaction water tank 100 through an overflow plate 500, and effluent after micro-electrolysis enters the biological rotating disk reaction tank 400 through the overflow plate 500.

More specifically, the end surface of the drum screen 200 is provided with a first rotating shaft 230, and the first rotating shaft 230 is connected with a first motor 240. The first motor 240 drives the drum screen 200 to rotate at a low speed through the first rotation shaft 230.

Further specifically, a feed inlet 250 is formed on the side wall of the trommel 200 for supplementing and adding the micro-electrolysis filler 300.

More specifically, the bio-disc 410 is rotated by the second motor 440 through the second rotation shaft 430. The second motor 440 rotates the bio-disc 410 at a low speed by means of the second rotation shaft 430. The diameter of the bio-disc 410 may be the same as that of the drum sieve 200, and the sizes of the bio-disc reaction tank 400 and the micro-electrolysis reaction water tank 100 may be the same, so as to facilitate the integration of the two units and better achieve the synchronization during the operation.
