Biochemical fish tank without filter cotton

Abstract

The invention discloses a biochemical fish tank without filter cotton. A biochemical chamber is arranged on a tank body, the interior of the biochemical chamber is provided with a plurality of ceramicrods or ceramic rings, a submersible pump is arranged under one end of the biochemical chamber and immersed under a liquid level of the tank body, a collector is arranged below a water inlet of the submersible pump, a water outlet of the submersible pump is connected with a water inlet of the biochemical chamber and one end of a water outlet pipe, the front end of the water inlet of the biochemical chamber is provided with an air inlet throttle gate, and the other end of the biochemical chamber is provided with a baffle and a water outlet of the biochemical chamber; and the water outlet of the biochemical chamber is connected with a straight pipe immersed under the liquid level, and the water outlet pipe passes through the interior of the biochemical chamber and leads to the bottom of thetank body along the side wall of the tank body. The fish tank disclosed by the invention has a simple structure, and is convenient to operate; sundries in water can be collected without the filter cotton, a motor has low power and low energy consumption, so that water resources are saved, time and labor are saved, and no new pollution is generated in the collection process; and the fish tank hashigh purification efficiency, a good effect, low costs and broad application prospects, and facilitates promotion and applications.

Description

technical field [0001] The invention relates to the technical field of ornamental fish breeding equipment, in particular to a biochemical fish tank without filter cotton. Background technique [0002] At present, the filtration methods of ornamental fish tanks and aquariums (referred to as fish tanks) mainly include upper filtration, lower filtration and side filtration. Their working principle is: through the water pump, the water at the bottom of the fish tank, the excrement of the fish, the residue of fish food and the suspended matter in the water (referred to as debris) are sucked and discharged to the filter cotton. However, the filter cotton only stops the slag of sundries, and the organic matter, ammonia, nitrogen, etc. in it are still released and dissolved in the water, which will cause new pollution to the water body. Therefore, it is necessary to increase the amount of ceramic rods or ceramic rings to produce a large number of nitrifying bacteria, and use nitrif...

Problems solved by technology

However, using filter cotton to filter will pollute the water body of the fish tank, and the method of pollution first and then treatment will do more harm than good
