A kind of aquaculture shrimp pond and sewage discharge method

Abstract

The invention discloses an aquaculture shrimp pond and a sewage discharge method, comprising a pond body, a shrimp cultivation area is arranged in the pond body, a plurality of mutually parallel grooves are arranged at the bottom of the shrimp cultivation area along its length direction, and the grooves are above the grooves. Install a shield assembly that can be lifted up and down by a hoist. Both ends of the shrimp farming area are equipped with a shrimp shell discharge area, and the shrimp farming area and the shrimp shell discharge area are separated by a partition, and the partitions on both sides are opened. There are multiple discharge holes, and the discharge holes correspond to the ends of the grooves one by one. A rope runs through the discharge holes on both sides of any groove, and the two ends of the rope are respectively wound on the rope driving devices on both sides of the pool body. , a silicone brush is distributed in the middle of the rope, and the silicone brush is in contact with the bottom surface of the groove; a tapered sleeve is fixedly installed on the partition outside the discharge hole, and the rope penetrates or passes through the discharge hole through the tapered sleeve. The shrimp farming pond in the present invention can automatically complete the cleaning work of the shrimp farming area, and has simple structure, convenient operation and low cost.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture shrimp pond and a sewage discharge method. Background technique [0002] During the shrimp farming process, a large amount of pollutants such as residual bait, feces, and shells from shrimp sloughs accumulate and cannot be transferred in time, resulting in the increase of harmful environmental factors such as ammonia nitrogen and nitrite in the water, and the occurrence of opportunistic pathogenic bacteria such as Vibrio A large number of breeding, harmful algae reproduction, resulting in the outbreak of large-scale diseases. [0003] At present, the field of shrimp farming often adopts a track-type shrimp pond. A water partition wall is added in the middle of the pond, and there is a gap between the water partition wall and the pool wall, so that when water enters and oxygenates, the water in the shrimp pond will Turning along the partition wall, the still wa...

Problems solved by technology

[0004] However, this method can only remove residual bait, feces and other pollutants in the water, but it cannot do anything for the shells that the shrimp shed during the growth process. If a large number of shrimp shells cannot be discharged in time, it will affect the water quality in the shrimp pond, leading to the death of shrimp poisoning
