Embodiment Construction
[0021] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0022] see figure 1 , figure 2 , image 3 , an impact-type integrated denitrification bioreactor of the present invention, which includes a cavity 101, a water distribution channel 201, and an outlet pipeline 202; the water distribution channel 201 and the outlet pipeline 202 are arranged on the upper part of the cavity 101, and the distribution The water tank road 201 is higher than the water outlet pipeline 202. In this embodiment, the vertical height difference between the water distribution tank road 201 and the water outlet pipeline 202 is 15 cm.
[0023] A sand layer 103 is provided in the cavity 101 to provide the attachment surface and anaerobic environment required by the denitrifying bacteria. In this embodiment, the thickness of the sand layer 103 is 60 cm, and the diameter of the sand is 0.2-1.2 mm; A transparent observ...

Abstract
The invention relates to an impact type integrated denitrifying bioreactor which comprises a group of cavities storing a plurality of layers of sand grains, a water tank distribution path arranged above the cavities, a water outlet pipeline arranged above the cavities and a water dividing plate arranged on the upper portions of the cavities. The plurality of layers of sand grains are located on the lower portion of the cavities. Vertical height difference is arranged between the water tank distribution path and the water outlet pipeline to maintain water level and generate required impact water flow. The water dividing plate is parallel to the vertical axis of the cavities, the water tank distribution path and the water outlet pipeline are respectively located on two sides of the water dividing plate to ensure that the water flow can flow out from the water outlet pipeline with the flow direction changed by 180 degrees after the water flow is contacted with a sand grain layer. Hairbrush protrusions are arranged on one side of the water dividing plate close to the water outlet pipeline to stop the sand grains from flowing out of the cavities with the water flow. The bioreactor can remove ammonia, nitrite and nitrate in water bodies of seawater aquaculture and freshwater aquaculture.
Description
technical field [0001] The invention relates to a bioreactor for simultaneously removing ammonia, nitrite and nitrate in seawater and freshwater aquaculture water. In particular, it relates to an impact-type integrated denitrification bioreactor. Background technique [0002] The shortage of water resources, environmental pollution and blind pursuit of production have resulted in the aging of fishing grounds, the decline of water environment quality, and even the spread of fish diseases, which have seriously affected the production and quality of aquatic products. In recent years, industrialized closed circulating water fish farming, as the main form of modern fish farming technology and industrialization, has received more and more attention. The research, introduction, and application of high and new technology in this field, to a certain extent, indicate the level of a country's fish farming technology. Some developed countries have seized the commanding heights in this ...
