Water treatment device for fish tank

Abstract

The invention specifically relates to a water treatment device for a fish tank. The water treatment device includes a shrinkage segment, a filtering segment and a diffusion segment; the filtering segment is a circuit pipe and includes an activated carbon filtering layer, a deodorization layer and a disinfection layer, the activated carbon filtering layer is positioned above the disinfection layer,and the deodorization layer is positioned below the disinfection layer; the shrinkage segment is conical, and the diameter of a conical small end of the shrinkage segment is equal to that of the filtering segment; the diffusion segment is conical, the diameter of a conical small end of the diffusion segment is equal to that of the filtering segment, and multiple water draining holes are formed inthe diffusion segment; one end of the filtering segment is fixedly connected with the conical small end of the shrinkage segment, and the other end of the filtering segment is fixedly connected withthe conical small end of the diffusion segment. According to the water treatment device for the fish tank, the filtering speed is high, the filtering effect is great, the activity of fishes cannot beinfluenced, and the device is safe to use and attractive in appearance.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a fish tank water treatment device. Background technique [0002] The main pollutants in the fish tank are organic matter, that is, fish feces, body fluids and other metabolites and residual bait. In view of this situation, the water treatment system mainly adopts biochemical treatment methods, that is, bacteria are used to decompose organic matter and purify the water quality. [0003] The treatment of fish tank water is currently treated with activated carbon, which can absorb heavy metals, a small amount of organic matter and a small amount of viral microorganisms, but it does not achieve good results, and it is troublesome to filter out granular or powdered activated carbon after use. Or the method of ultraviolet sterilization is adopted, but this method cannot remove substances such as organic matter or heavy metals. [0004] Chinese invention patent CN205398350U ...
