Device for recycling, filtering and utilizing wastewater of large fish tank

Abstract

The invention discloses a device for recycling, filtering and utilizing the wastewater of a large fish tank. The device comprises a body and is characterized in that a fishing cavity is arranged in the body, a hollow pipe is fixedly arranged on the left side of the body, a water inlet pipeline is communicated between the hollow pipe and the fishing cavity, a collecting device for collecting garbage such as duckweeds and water plants is arranged in the fishing cavity, and the wastewater is pumped into the fishing cavity through the water inlet pipeline. The device has the advantages that automatic water changing, water plant cleaning, manure cleaning, water filtering and the like can be performed on the large fish tank; compared with traditional simple physical and chemical filtering, the device can collect and separate the water plants falling from the fish tank first to prevent the fallen water plants from affecting the attractiveness of the fish tank and can independently collect sludge and manure and directly separate the sludge and the manure from the wastewater to reduce the contact time of manure and water so as to reduce the generation of ammonia and nitrite.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a device for recycling, filtering and utilizing large-scale fish tank sewage. Background technique [0002] With the improvement of people's living standards, more and more people like to breed ornamental fish to cultivate their own sentiments. In some super large fish tanks, after a period of operation, the water in the fish tank will not be replaced for a long time. The increase of nitrite and ammonia will affect the water quality, which will destroy the microbial balance in the bathtub and lead to the death of fish; [0003] In order to solve this problem, some filter systems are generally added to this large fish tank to prolong the time of water change. The existing filter systems are generally pure physical filtration and simple biochemical filtration, and physical filtration needs to be jacked up for replacement.

Problems solved by technology

[0002] With the improvement of people's living standards, more and more people like to breed ornamental fish to cultivate their own sentiments. In some super large fish tanks, after a period of operation, the water in the fish tank will not be replaced for a long time. The increase of nitrite and ammonia will affect the water quality, which will destroy the microbial balance in the bathtub and lead to the death of fish;

[0003] In order to solve this problem, some filter systems are generally added to this large fish tank to prolong the time of water change. The existing filter systems are generally pure physical filtration and simple biochemical filtration, and physical filtration needs to be jacked up for replacement. Some filter cotton and other items are still very inconvenient, and simple biochemical filtration refers to cultivating some nitrifying bacteria to decompose some feces, but the feces output of large fish tanks is very large, and the traditional filtration system can hardly withstand this large amount of feces. Moreover, there will be creatures such as duckweed and aquatic plants in the fish tank, which will easily cause the filter device to be blocked.
