Abstract

The invention relates to a biological filter provided with a modular packing layer and a mounting method of the modular packing layer. The biological filter is sequentially provided with a water distribution region, a supporting layer, a filter material layer and a clear water region from bottom to top; the modular packing layer is also arranged in the biological filter, the modular packing layer is composed of multiple packing modules, each packing module comprises a square cage body and packing arranged in the square cage body; each square cage body is fixed in the biological filter by virtue of a support and can be separately disassembled; and the packing is biological contact oxidation packing or suspended packing. The biological filter provided by the invention has the advantages that the biological contact oxidation packing or suspended packing is additionally arranged above the filter material layer of the biological filter, so that the handing capability of the biological filter can be greatly improved; meanwhile, the modular packing layer is simple in structure and is easy to disassemble and replace.

Description

technical field [0001] The invention relates to the technical field of wastewater purification treatment, in particular to an improved biological filter capable of improving treatment effect. Background technique [0002] When the biological aerated filter adopts a large aeration rate, the treatment effect of organic matter and ammonia nitrogen is good, but the dissolved oxygen in the effluent is high, and a large amount of carbon source will be consumed when entering the post-denitrification biological filter; while the return flow into the pre-denitrification biological filter After the pond, it will cause high dissolved oxygen in the denitrification biological filter, which will affect the denitrification effect; and when the biological aerated filter adopts a small aeration volume, the treatment effect of organic matter and ammonia nitrogen is not good. Contents of the invention [0003] The invention provides a biological filter with a modular packing layer and an ins...
