specific Embodiment approach 1

[0017] Specific implementation mode one: combine Figure 1-3 Describe the present embodiment. The micro-animal attachment filler in this embodiment includes a carrier 1, a metal grid 2 and a support frame 3. The carrier 1 is a mesh formed by interlacing and weaving fiber materials, and the support frame 3 is horizontally arranged There are several metal grids 2, the carrier 1 is fixed on the upper surface of the metal grids 2, and there is a gap between the carrier 1 and the metal grids 2.

[0018] The filler in this embodiment can increase the density of micro animals per unit volume and improve the stability of the system. The device has the advantages of strong stability, high biological density and simple operation, and the predation efficiency of the sludge is increased by more than 30% compared with the traditional micro-animal attachment filler.

[0019] The filler can simplify the attachment operation of micro-animals, provide a stable and suitable living environment ...

specific Embodiment approach 2

[0021] Embodiment 2: This embodiment is different from Embodiment 1 in that: the fiber material is one or more of nylon fibers, superfine fibers, polypropylene fibers, and polyethylene fibers. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the metal grid 2 is horizontally fixed in the support frame through the slot 4 . Others are the same as in the first or second embodiment.

Abstract

The invention relates to miniature animal attaching packing. By the aid of the miniature animal attaching packing, technical problems that miniature animals in existing miniature animal attaching packing cannot stably grow, the existing miniature animal attaching packing is low in biological density and poor mud predation effects are realized can be solved. The miniature animal attaching packing comprises carriers, a plurality of metal grids and a support frame. The carriers are netted objects, fiber materials are arrayed and woven in a staggered manner to form the netted objects, the metal grids are horizontally arranged in the support frame, the carriers are fixed to the upper surfaces of the metal grids, and gaps are reserved between the carriers and the metal grids. The miniature animal attaching packing has the advantages that the miniature animal attaching packing is high in system stability and mud reduction efficiency and easy to operate and is applied to the field of sewage treatment, and miniature animals can be attached to the miniature animal attaching packing easily.

Description

technical field [0001] The invention relates to a filler, in particular to a filler for sewage treatment. Background technique [0002] A large amount of sludge is produced in the process of urban sewage treatment, which contains many toxic and harmful substances, and improper treatment will lead to serious environmental problems. The existing sludge reduction methods mainly include lysis-recessive growth, uncoupling metabolism, metabolic balance, and biological predation. Among them, the biological predation technology has the advantages of pure ecology, no secondary pollution, low treatment cost, and good sludge reduction effect. Biological predation technology mainly realizes sludge reduction through the ingestion and lysis of sludge by micro-animals. In the process of predating sludge, a part of the sludge is ingested by micro-animals as food, and the sludge is reduced; a part of the sludge is broken and lysed and released in the form of nutrients such as carbon and ni...
