Problems solved by technology

[0002] In the process of aquaculture, it is necessary to use a filter device to circulate and filter the aquaculture water body. The filter materials in the traditional filter device are ceramsite, quartz sand, etc., which are mainly physical filtration, which can absorb various impurities in the aquaculture water body. Dirt, but after a period of use, these filter materials contain a large amount of impurities, especially a large amount of organic impurities, which will not only not clean the aquaculture water, but will destroy various parameters of the aquaculture water body, directly Affect the breeding effect, so now a new type of filter that can solve the above problems is needed

Abstract

The invention discloses a tower-type clam worm biofilter which comprises a tower-shaped filter body (1), and is characterized in that a water inlet pipe (2) is disposed at the top end of the tower-shaped filter body (1); a water outlet pipe (3) is disposed at the lower part of the tower-shaped filter body (1); an inverted cone-shaped dirt collector (4) is disposed at the bottom of the tower-shaped filter body (1); a dirt discharge pipe (5) with a valve is disposed and communicated with the cavity of the dirt collector (4); a clam worm layer (6), a clapboard (7) with meshes, a ceramsite layer (8), a quartz sand layer (9) and a volcanic rock layer (10) are orderly disposed from up to down in the inner wall of the tower-shaped filter body (1) between the water inlet pipe (2) and the water outlet pipe (3); the clam worm layer (6) has a thickness of 20-30 cm, and is made of Chinese medical stone with a particle size of 0.5-1 mm.

Description

technical field [0001] The invention relates to a filter tank structure, in particular to a tower-type nereis biological filter tank. Background technique [0002] In the process of aquaculture, it is necessary to use a filter device to circulate and filter the aquaculture water body. The filter materials in the traditional filter device are ceramsite, quartz sand, etc., which are mainly physical filtration, which can absorb various impurities in the aquaculture water body. dirt, but after a period of use, these filter materials contain a large amount of impurities, especially a large amount of organic impurities, which will not only not clean the aquaculture water, but will destroy various parameters of the aquaculture water body, directly Affect the breeding effect, so a new type of filter that can solve the above problems is needed now. Contents of the invention [0003] In order to solve the above-mentioned shortcomings in the prior art, the present invention proposes...
