Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0025] Such as figure 1 As shown, the aquaponics and algae cooperative symbiotic culture device of the present invention includes a fish tank 9 , a planting tank 7 and a culture tank 8 . The fish tank 9 is a cuboid structure, and its top is provided with a "concave" top plate for placing the planting tank 7; There is a layer of substrate 14, which is used to fix the vegetables planted, and the substrate 14 used in the present embodiment is preferably ceramsite; The fish tank 9 is provided with an isolation tank 6, and the isolation tank 6 is provided with a culture tank 8 for cultivating microalgae. It can also ensure that microalgae and fish are isolated from each other; fish tank 9, isolation tank 6 and cultivation tank 8 are all consistent in height, and in the presen...

The invention provides a fish, vegetable and algae cooperative symbiotic culture device and method, which belong to the technical field of aquaculture and vegetable planting. The culturing device includes a fish tank, a vegetable planting tank, a microalgae culture tank, an air pump and a water pump. The planting tank is arranged above the fish tank, the culture tank is arranged in the fish tank, the air pump is arranged outside the fish tank, and the water pump is arranged in the fish tank. The water pump can pump nitrogen-containing substances produced by microorganisms in the fish tank to decompose fish feces and fish food into the planting tank to provide nutrients for vegetables to grow, while microalgae can provide sufficient oxygen for fish life and remove vegetables. Absorb endless nitrogen-containing salts, avoiding the harm to fish caused by the accumulation of nitrogen-containing salts. In addition, microalgae can enrich heavy metals, harmful gases, degrade particulate pollutants, and pump air into the microalgae cultivation tank, which can purify indoor air and improve air quality.
Description
technical field [0001] The invention belongs to the technical field of aquaculture and vegetable planting, and in particular relates to a fish, vegetable and algae cooperative symbiotic culture device and method. Background technique [0002] The aquaponics system has been developed for a long time. The use of fish feces as plant fertilizers existed a long time ago. Fish feces and bait will be decomposed by bacteria and converted into nitrogenous salts (mainly nitrate and nitrous acid) salt) to be absorbed by plants. In theory, a well-managed aquaponics system can improve the utilization rate of nutrients in aquaculture and achieve the purpose of water purification, but the promotion of aquaponics system is currently limited by its low nitrogen utilization rate. According to reports, more than 60% of the nitrogen in the current aquaponics system may not be utilized by plants or fish, and it usually remains in the water body or overflows in the form of gas, so there is an ac...
