Problems solved by technology

For these organic particles to be removed by common methods, there will be problems such as difficult operation, high input cost, and new pollution, which have not been implemented in production practice.
[0005] If the wastewater from shrimp farming is not treated and discharged directly, it will form a pollution source, pollute the environment around the farm, and eventually lead to the pollution of the nearby sea area, causing the offshore ecological crisis

Embodiment 1

[0040] see figure 1 , figure 2 and image 3 . A kind of treatment method of industrialized prawn culture waste water, comprises the steps:

[0041] (1) Build wastewater treatment facilities outdoors: build an adsorption pond 5, a ventilation pond 9, a sediment recovery pond 11, and a biological purification pond 17 outside the industrialized shrimp farming workshop 1; The pipeline 8 is connected to the ventilation pool 9 and the biological purification pond 17 in turn; the sediment recovery tank 11 is respectively connected to the adsorption pool 5 and the ventilation pool 9 through the water pipeline 8 equipped with the valve 7; between the wastewater treatment facilities, the waste water depends on the water level difference natural flow in and out;

[0042] (2) Add muddy silt from the tidal flat to the workshop wastewater: when the wastewater is discharged from the culture pond 2 of the industrial shrimp farming workshop 1, put muddy silt at the exit 4 of the wastewate...

Embodiment 2

[0053] see figure 1 , figure 2 and image 3 . A method for treating industrialized prawn farming wastewater. On the basis of the technical solution recorded in Example 1, step (1) the adsorption pool 5, the ventilation pool 9 and the sediment recovery pool 11 all use cement pools, which are durable and durable. It is easy to clean and saves cost; step (1) the material of the water pipeline 8 is PVC, which is both anti-corrosion and cheap.

Embodiment 3

[0055] see figure 1 , figure 2 and image 3 . A method for treating industrialized prawn farming wastewater. On the basis of the technical solution recorded in Example 1, step (1) the depth of the ventilation pool 9 is 30 cm, and the wastewater level is 20 cm. Such a shallow water level is conducive to the rapid increase of wastewater dissolved oxygen concentration.

Abstract

The invention relates to the field of aquatic product waste treatment, and discloses a factory-like prawn culture wastewater treatment method. The factory-like prawn culture wastewater treatment method comprises the following 11 steps of (1) constructing a wastewater treatment facility outdoors; (2) adding muddy silt of mudflat into workshop wastewater; (3) removing organic particles in the wastewater in an adsorption tank; (4) adding dissolved oxygen to the wastewater in a ventilation pool; (5) recycling sediments in a sediment recycling pool; (6) oxidatively decomposing the sediments in a sunning ground; (7) cultivating phytoplankton by utilizing nutritive salt contained in the wastewater in a biological purification pond; (8) arranging an oyster culture cage in the biological purification pond; (9) filtering and feeding the phytoplankton and suspended particles by oysters in the biological purification pond; (10) constructing an ecological food chain in the biological purification pond; and (11) conducting wastewater reutilization. By means of the factory-like prawn culture wastewater treatment method, the organic particles in water are successfully removed, the dissolved oxygen in water is increased, the nutritive salt in water is consumed, the pond food chain is constructed, purified water cyclic utilization is achieved, and remarkable environmental protection and economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of aquatic waste treatment, in particular to a treatment method for industrialized prawn breeding wastewater. Background technique [0002] Industrial farming of Penaeus vannamei is a farming model developed in my country's coastal fishery in recent years. Shrimp are raised in off-season and sold before the Spring Festival. The price is high and the benefits are great. It is of great significance to solve the production and life of coastal fishermen and maintain the economic development of fishery. However, there are indeed some problems that cannot be ignored in industrialized shrimp farming. [0003] Due to the high density of industrialized shrimp farming, the high temperature of the breeding water, the large amount of inputs in the breeding pond, and the generation of residual bait and other wastes, the wastewater discharged during the shrimp farming process contains a large amount of organic particles, and the co...
