The main components of the fish and vegetable symbiosis system mainly include the breeding box, filtration system, biochemical system and other devices. Today, Hui Nong.com Xiaobian will tell you about the detailed explanation of the fish and vegetable symbiosis system.
First, the breeding box
It must be kept watertight, and the assembly piping and drain valves should be checked frequently to avoid the complete loss of water and the death of the fish. The shape of the culture box will affect the flow of water. The irregular shape of the culture box will form a dead angle where water cannot flow, causing the accumulation of excrement to produce harmful substances and toxins. Therefore, it is better to use a drum or a square bottom. The circular barrel makes the circulation of water more uniform, and enables the sediment to be discharged by centrifugal force concentrated on the center of the circle.
The culture box is preferably made of reinforced plastic or fiberglass that is durable, lightweight and easy to install. The color inside the culture box is preferably white or light, and it is easy to observe the behavior of the fish and the accumulation of sediment. The top of the culture box must be covered to avoid axillary algae, and it can also prevent the fish from jumping out or falling into the debris.
The breeding box needs to be set with certain safety mechanism. For example, the pump water pumping port should not be inserted into the bottom of the bucket to reserve a certain level of safe water level, the drain pipe mouth and the bottom of the bucket to maintain a certain distance or install a low water level warning device. Generally speaking, the newly installed system will not be balanced due to the imbalance of bacteria and algae, and the water quality must be monitored frequently. However, as long as it is not much different from the standard value, it is not necessary to make interference adjustment. It usually takes about 1 month to stabilize. .
Second, the filtration system
The sediment and excretion in the culture tank are mainly separated from the water. The longer these impurities are deposited in the culture tank, the more harmful substances are generated, and the pipeline blockage may affect the water flow.
There are many types of filtration, the simplest way is the screen, it must be cleaned frequently to avoid blockage. It can also be filtered using a filter bucket filled with special materials. The filtration system removes approximately 60% of the solid waste and reduces the accumulation of organic matter in the system, which is extremely helpful in maintaining water quality.
Third, the biochemical system
Part of the fish's excreta will dissolve directly in the water and will not be easily removed by filtration. This type of excretion mainly exists in the form of ammonia nitrogen, which is not only absorbed by plants but also poisonous to fish. The biochemical system uses live nitrifying bacteria to convert ammonia into nitrate. The biochemical system is commonly used in biochemical spheres. It has a special shape and a large surface area. It is filled with biochemical balls in biochemical systems to increase nitrification. s efficiency.
Other materials available include biochemical cotton, foamed stone, volcanic rock, ceramic ring, nylon mesh, and brush. For systems with cultivated substrates, there is no need to install a biochemical system separately, because the bed substrate itself is a biochemical filter, but it is still necessary to install a filter to filter solid impurities, so as to avoid accumulation of too much solid organic matter in the culture substrate, resulting in decomposition. Produces toxic substances and blocks the pipeline.
The above is the detailed explanation of the fish and vegetable symbiosis system device technology compiled by Huinong . I hope to help you.
