Abstract

The invention belongs to sewage treatment equipment, and particularly relates to a vertical baffling type denitrification filter for a solid carbon source. The filter comprises a solid carbon source pool, an inorganic filter material pool and a water tank which is connected between the solid carbon source pool and the inorganic filter material pool in a clamping way, and the solid carbon source pool is communicated with the upper part of the inorganic filter material pool; a partition plate with filter heads is transversely arranged in the middle of the solid carbon source pool, a solid carbon source layer is filled above the partition plate, a first water distribution layer is arranged below the partition plate, and a first water inlet pipe is arranged in the first water distribution layer; the middle part of the inorganic filter is also transversely provided with a partition board with filter heads, an inorganic filter material layer is filled above the partition board, a second water distribution layer is arranged below the partition board, and a first water discharge pipe is arranged in the second water distribution layer. The filter can realize the operation mode of 'up-down-after-up', reduce the dissolved oxygen content of inlet water and further improve the denitrification effect of the filter.
