Combined packing box for water quality purification of prawn culture pond

Abstract

The invention belongs to the technical field of aquaculture equipment, and relates to water quality purification equipment for aquaculture, in particular to a combined packing box for water quality purification of a prawn culture pond. Densely arranged elliptic pores are formed in the periphery and the lower part of a box body, and a drawer type cover is arranged on the upper side surface of the box body. A square space enclosed by partition plates with pores is arranged in the middle of the inner cavity of the box body to divide the whole box body into an inner chamber and an outer chamber. The outer chamber of the box body is filled with a packing B which is used in equal volume combination of one or more of rigid packings including polyurethane, loofah and crushed coral; and the inner chamber of the box body is filled with a packing A which is a soft packing including fiber hair balls, the diameter of the packing is 4-6 cm, and an anoxic zone can be formed after operation to facilitate the removal of nitrate. A fixing belt fixing the box body to a transverse bar is arranged on the upper side of the box body. The main structure of the combined packing box is simple, the design idea is ingenious, the manufacture cost is low, the application environment is friendly, and market prospects are broad.

Description

Technical field: [0001] The present invention belongs to the technical field of aquaculture equipment, and relates to a water purification equipment for aquaculture, in particular to a combined stuffing box used for water purification of prawn culture. The stuffing box can be assembled according to the size of the breeding tank, which can quickly remove ammonia, nitrite and nitrate in the breeding water body, so that the breeding tank has the functions of prawn breeding and water purification at the same time, which is especially suitable for high-density prawn breeding systems. technical background: [0002] In the process of prawn farming, prawn excretion and decomposition of residual bait will produce ammonia and nitrite. If they cannot be removed in time, ammonia or nitrite will accumulate. Ammonia and nitrite have a greater impact on the respiratory system of prawns. It is an important cause of fulminant shrimp disease. Therefore, ammonia and nitrite are the main removal ta...

AI Technical Summary

Problems solved by technology

In order to maintain the ammonia and nitrite in the culture system at a low concentration, it is necessary to ensure that there are a certain number of nitrifying microorganisms in the system. Source, using oxidized inorganic nitrogen as an energy source, slow growth and reproduction, sensitive to changes in environmental factors, making it at a disadvantage in competition with heterotrophic bacteria
