Problems solved by technology

However, in the process of aquaculture water treatment, due to the lack of anaerobic environment, studies have pointed out that there is no obvious denitrification reaction. In the process of converting from NH4 + to NO and then to NO2, oxygen needs to be consumed, and the pH will change accordingly
However, due to the limitation of residence time, the current circulating water treatment system often cannot meet the optimal conditions for denitrification by nitrifying bacteria, and cannot achieve the effect of complete denitrification.
In this case, the aquaculture water still contains nitrogen after treatment. Although NO is not particularly toxic to fish, it will also cause harm to fish if it accumulates for a long time. recycling

Abstract

The invention discloses a totally-enclosed circulating water aquaculture device for aquatic hazel grouse feed. The device comprises a circulating water pump, a water level measuring instrument, a cylindrical shell, a feeding port and a water inlet pipe; the circulating water pump is installed at the left of the cylindrical shell; a drainage pipe is installed at the left side of the circulating water pump and the drainage pipe passes through a valve cover and is installed inside the cylindrical shell; the water outlet pipe is provided with an air pipe and the air pipe is provided with a check vale; the water level measuring instrument is installed at the bottom of the cylindrical shell; the cylindrical shell is provided with a filtering device, a biochemical cotton, an aquaculture cabin anda microbe filter bed which are successively arranged from top to bottom; a nitrogen processing device is installed under the right of the cylindrical shell; the feeding port is installed at the rightside of the aquaculture cabin; the water inlet pipe is installed at a right side of the cylindrical shell. The novel structure design of the invention effectively solves the nitrogen accumulation problem in the process of aquaculture water treatment, ensures the complete biological denitrification, realizes a true secondary aquaculture water filtration device for aquaculture, saves water resources, and reduces pollution.

Description

technical field [0001] The invention relates to the technical field of circulating water treatment equipment, in particular to a fully enclosed circulating aquaculture device for aquatic dragon feed. Background technique [0002] At present, in order to improve the nutritional value of flying dragons, today's breeders have changed the feed of flying dragons and added aquatic feeds. Aquaculture technology is changing from traditional models to industrialized farming. In the process of industrialized farming, the most important new technology is circulation. Aquaculture technology. The core of the recirculating water fish farming system is the aquaculture water treatment system, and around the water treatment system, a fish disease prevention and treatment system suitable for recirculating aquaculture is established. In aquaculture water, pollutants mainly come from fish excrement and bait residues, including four main elements: carbon, nitrogen, phosphorus, and sulfur. The m...
