Online treatment device and method for ammonia nitrogen of marine culture water body

Abstract

The invention discloses an online treatment device and method for ammonia nitrogen of a marine culture water body. N left movement devices and N right movement devices are symmetrically mounted at a left bank side and a right bank side of a culture pond respectively at equal intervals; a corresponding ammonia nitrogen treatment box is suspended on each left movement device and each right movementdevice respectively; the ammonia nitrogen treatment boxes are driven to move up and down, and left and right in the culture pond through controlling the working of the N groups of left movement devices and right movement devices, so that the comprehensiveness of ammonia nitrogen treatment is ensured to a certain extent; four middle-size stirrers are mounted at the peripheries of the ammonia nitrogen treatment boxes and are used for uniformly stirring ammonia nitrogen concentration of the water body at the periphery, and detection and treatment are convenient to realize; three middle-size stirrers are mounted at the bottom of an electrolysis reactor, the diffusion of activated chlorine can be accelerated and the activated chlorine and ammonia nitrogen are subjected to oxidization reductionreaction, so that the ammonia nitrogen treatment speed is improved; meanwhile, the ammonia nitrogen concentration uniformity of water in the electrolysis reactor is ensured; each part of the whole device is controlled to work by utilizing an MCU (Microprogrammed Control Unit) control system and automatic online treatment of ammonia nitrogen of the culture water body is effectively realized.

Description

technical field [0001] The invention relates to the field of mariculture, in particular to an on-line treatment device and method for ammonia nitrogen in mariculture water, aiming at reducing the concentration of ammonia nitrogen in the aquaculture water. Background technique [0002] In recent years, the mariculture industry has developed rapidly. However, due to insufficient scientific and technological support, there are still many problems in this industry that have not been effectively resolved, which seriously restricts the healthy and rapid development of the industry. Among them, the most typical problem is the problem of ammonia nitrogen treatment in aquaculture water. The main sources of ammonia nitrogen in aquaculture water are residual bait in water, fish metabolites, and fertilizers. Due to the high density of industrial aquaculture, a large amount of fertilizer and fertilization are required, and the nitrogen-containing organic matter in the water increases, ca...

Problems solved by technology

The main source of ammonia nitrogen in aquaculture water is residual bait in water, fish metabolites, and fertilizers. Due to the high density of industrial aquaculture, a large amount of fertilizer and fertilization are required, and the nitrogen-containing organic matter in the water increases, causing the water to be polluted

A large number of studies have shown that the harm of ammonia nitrogen to aquatic organisms mainly refers to non-ionic ammonia. After non-ionic ammonia enters the aquatic organisms, it will have a significant impact on the enzyme hydrolysis reaction and membrane stability, making it difficult to breathe, not ingest, resist Decreased strength, convulsions, coma and other phenomena will affect the physiological and biochemical indicators and growth status of aquatic organisms. In severe cases, it will lead to the death of a large number of cultured organisms and cause economic losses.
