Ecological self-purified integrated aquarium fish circulating water culturing system

Abstract

The invention relates to the technical field of culturing of aquarium fishes and particularly relates to an ecological self-purified integrated aquarium fish circulating water culturing system. The system comprises a fish culturing pond, a pollutant receiving pond, biological filters, artificial wetlands and a stored water reusing pond, wherein the stored water reusing pond is communicated with the fish culturing pond; the pollutant receiving pond and the biological filters are located right under the fish culturing pond; the artificial wetlands and the stored water reusing pond are arranged on one side of the fish culturing pond side by side; all subunits are compact in structures and are connected with each other through porous devices; the pipeline connection is eliminated; the water discharging instability caused by the accumulation of the pollutants on the inner wall due to overlong system pipeline is avoided; the effective volume utilization ratio is increased. According to the ecological self-purified integrated aquarium fish circulating water culturing system, the residual feeds, the excrements and the nitrogen-phosphorus nutrients in the discharged culturing water can be filtered and purified; three levels of biological filters and explosive cotton are successively used for gradually purifying the culturing water; the culturing water is finally purified by two levels of artificial wetlands; the landscape effect can be obviously improved; the fish culturing water can be recycled; the water resource can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of ornamental fish cultivation, in particular to an ecological self-purification integrated ornamental fish circulating aquaculture system. Background technique [0002] After a long time in the fish tank, the feces and residual bait of the fish will affect the water quality, and some bacteria will grow, which will affect the health of the fish. Whether a tank of high-quality ornamental fish can be raised depends on the water quality environment, which directly affects the survival and reproduction of ornamental fish. Currently commonly used water quality improvement methods are: (1) Exposure method. It is mainly aimed at aquariums that need to be replaced with new water regularly. Now people choose tap water or well water to replace new water. This kind of fish water contains chlorine or chloride, which will stimulate the respiration of fish gills and affect the growth and health of fish. Therefore, befo...

Problems solved by technology

Exhaustive water changes will cause waste of water resources. Even if the above various purification methods are used comprehensively, the water quality will not continue to be good. It needs to be used in conjunction with water changes, and the water cannot be completely closed and recycled.

[0003] At present, the ecological purification treatment of ornamental fish breeding water mainly includes artificial wetland purification or biological filter purification, etc., but if the two are used together, the system will occupy too much area and the invalid volume will increase, which will affect the decontamination effect. Therefore, a design It is necessary to set up a suitable volume and fully enclosed recirculating aquaculture system
