Embodiment 1
[0015] Three steps of saline-alkali groundwater improvement technology: the first step is construction and technical requirements. The sedimentation tank 2 is a square tank made of concrete with a side length of 50m and a depth of 3m. An aeration plate 12 is laid on the bottom of the tank, and the tank wall is provided with inlets and outlets for easy work. People come in and out to clean the bottom of the pool. There are 2-3 adjacent sedimentation tanks in the factory area, which are convenient for cleaning and alternate use.
[0016] The manganese sand filter tank 3 is a glass tank shell with a nominal diameter of 3600mm and a backwashing strength of 15L / m 2 ·S, with a processing capacity of 100 m / H, filled with natural manganese sand, the manganese form is mainly manganese oxide, and the manganese content (calculated as MnO2) is not less than 35%. After the underground brine passes through the manganese sand filter, it can effectively remove metal ions such as manganese an...

Abstract
The invention provides equipment for culturing penaeus vannamei by saline-alkaline underground water based on factory water treatment. The scheme is implemented by the following technological means: the equipment mainly comprises a saline-alkaline underground well 1, a settling pond 2, a manganese sand filter tank 3, a filter plate I 4, an activated carbon treatment tank 5, a filter plate II 6, aworkshop treating pond 7, an aeration disc II 8, an air blower II 9, a boiler 10, a fresh water tank 11, an aeration disc I 12, a blow-off pipe I 13, a blow-off pipe II 14, a heat pipeline 15, a service reservoir 16, an air blower I 17, a bleaching powder input device 18, a sodium thiosulfate input device 19 and a potassium chloride input device 20. The equipment has beneficial effects of being reasonable and practical in design and capable of removing manganese, iron, brine bromide and the like, regulating salinity and alkalinity by adding fresh water and balancing ionic composition in water,so that aquaculture water quality meets the growing demand of penaeus vannamei. Effective development and utilization of saline-alkaline wastelands are realized, and the shortage situation of coastalfishery lands is relieved.
Description
technical field [0001] The invention relates to the technical field of saline-alkali groundwater treatment and cultivation, in particular to equipment for saline-alkali groundwater industrialized water treatment and cultivation of Penaeus vannamei. Background technique [0002] Penaeus vannamei, commonly known as white-legged shrimp or white-legged shrimp, is a wide-temperature and wide-halt tropical shrimp. It is mainly distributed in the tropical waters of the western Pacific coast of the United States, from the Gulf of Mexico to the central part of Peru, and is more concentrated in the waters near Ecuador. It is one of the three most productive species in the world. It naturally inhabits sea areas with a water depth of 0-70m. It is omnivorous and has three characteristics: strong adaptability, fast growth, and strong disease resistance. It can grow as long as the protein ratio in the bait accounts for more than 20%; After one day of cultivation, it can grow into an adult...
