Problems solved by technology
At present, the widely used treatment methods for removing ammonia nitrogen, phosphorus and organic matter in sewage include chemical treatment and biological treatment. Although chemical treatment has fast processing speed and good effect, chemical treatment has high cost and secondary pollution.
In recent years, biological treatment of aquaculture sewage has been widely used, but the efficiency is limited, and it is greatly affected by the environment, especially the low temperature in the northern region seriously affects the microbial activity.
Therefore, the traditional sewage treatment method has problems such as high cost and cumbersome maintenance. With the continuous improvement of environmental protection requirements, the sewage treatment technology of the aquaculture industry will restrict the development of the economical aquaculture industry

The invention discloses a device for rapidly treating aquaculture wastewater by using a magnetic field. The device comprises a filter pool, a wastewater degradation pool and a magnetic flour treatmenttank, wherein the filter pool is communicated with to-be-treated aquaculture wastewater, a water outlet of the filter pool is connected with a water inlet of the wastewater degradation pool, a wateroutlet of the wastewater degradation pool is communicated with the magnetic flour treatment tank, the magnetic flour treatment tank is internally provided with a magnetic adsorption component for recycling the magnetic flour, and the wastewater degradation pool is provided with a magnetic flour input port. The device has a simple structure, can treatment wastewater efficiently, can recycle magnetic flour rapidly, and greatly lowers the wastewater treatment cost. The device can recycle magnetic flour rapidly and conveniently, and has the characteristics of being efficient and low-cost, consuming less energy, being easy to operate and being fast.
Description
technical field [0001] The invention relates to a device and method for quickly treating aquaculture sewage by using a magnetic field, which belongs to a sewage treatment device. Background technique [0002] Modern intensive farming has the advantages of high breeding density, fast growth, water saving and high resource utilization, and is one of the important directions for the development of agricultural modernization. The sewage treatment technology required in the industrial aquaculture process is an important technical support for the development of industrial aquaculture, and the sewage treatment technology is the key and core technology of the recirculating aquaculture system. Aquaculture sewage also has its own characteristics due to the particularity of the industry. The composition of aquaculture sewage is complex and mainly contains a large amount of pollutants such as ammonia nitrogen, phosphorus, suspended particles, colored substances and organic matter. At ...
