Aquaculture wastewater treatment device

Abstract

The invention discloses an aquaculture wastewater processing device which comprises a water pond and a breeding pond arranged in the water pond, the breeding pond is provided with a water inlet and a water outlet, the breeding pond is internally provided with a sediment area, drive pieces enabling water in the water pond to flow from the water inlet of the breeding pond to the water outlet of the breeding pond are arranged in the water pond, the water pond is further internally provided with a guide plate, the sediment area is arranged at the position, close to the water outlet, of the breeding pond, the bottom face of the sediment area is lower than that of the breeding pond, and the sediment area is internally provided with a pollutant discharging assembly for discharging pollutants on the bottom face of the sediment area. By the adoption of the aquaculture wastewater processing device, sediment in the sediment area can be processed timely, and bred aquatic products cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a treatment device for aquaculture wastewater. Background technique [0002] Aquatic products such as fish and shrimp are an important source of protein for human beings. With the rapid growth of population, large-scale aquaculture has developed rapidly. However, the wastewater rich in nitrogen and phosphorus generated during the aquaculture process is discharged into rivers, lakes and other water bodies At the same time, in the aquaculture pond, when the concentration of ammonia nitrogen and nitrite nitrogen accumulated in the aquaculture water is too high, it will have a strong poisonous effect on fish and shrimp, and even cause Therefore, the purification and recycling of aquaculture wastewater has become an important part of reducing water pollution and saving water resources in the process of aquaculture, and the treatment of aquaculture wastewater has become a hot spot ...

Problems solved by technology

[0002] Aquatic products such as fish and shrimp are an important source of protein for human beings. With the rapid growth of population, large-scale aquaculture has developed rapidly. However, the wastewater rich in nitrogen and phosphorus generated during aquaculture is discharged into rivers, lakes and other water bodies At the same time, in the aquaculture pond, when the concentration of ammonia nitrogen and nitrite nitrogen accumulated in the aquaculture water body is too high, it will have a strong poisonous effect on fish and shrimp, and even cause Therefore, the purification and recycling of aquaculture wastewater has become an important part of reducing water pollution and saving water resources in the process of aquaculture, and the treatment of aquaculture wastewater has become a hot spot in the current research on water environment governance.

[0003] The existing ponds for aquaculture have a relatively simple structure. During the aquaculture process, the ponds need to be cleaned regularly, otherwise the water quality will deteriorate, causing self-pollution of the aquaculture, leading to illness or death of the aquaculture objects

At present, aquaculture ponds are basically unable to deal with aquaculture waste, and they are basically static water aquaculture, which cannot perform large-scale water changes. A large amount of excrement such as feces and residual bait accumulates in the middle and late stages of aquaculture, resulting in deterioration of water quality and a large number of harmful microorganisms. The stress has seriously affected the growth and survival of the breeding objects, resulting in a decline in the success rate of breeding, and has had a great impact on the quality and safety of aquatic products
