Description
Technical field
The invention belongs to aquaculture system nitrite degradation field, be specifically related to a kind of water nitrite degradation agent.
Background technology
Nowadays most of cultured fishes are mostly that wild species is directly entered artificial cultivation, and therefore the quality of artificial cultivation water quality environment directly affects quality and the survival rate of cultured fishes. Breeding water body nitrite, ammonia nitrogen, hydrogen sulfide, pH value, chemical oxygen consumption (COC) equal size height will dominate the quality of cultivation water. In breeding process, if the indexs such as breeding water body nitrite, ammonia nitrogen, hydrogen sulfide, pH value are too high, the aquatic animal giving cultivation is brought very big harm.
Nitrite is the intermediate product that ammonia is converted in nitrate process, the a large amount of excremental accumulation of aquatic animal in the residual bait that stays due to substantial amounts of bait throwing in breeding water body, water body, have to regularly use disinfectant sterilization, but disinfectant can be killed harmful and useful antibacterial all simultaneously, cause that oxygen supply is not enough, the nitrogen nitrifying process causing a large amount of accumulation is obstructed, further result in ammonia nitrogen and content of nitrite in breeding water body high, but owing to the conversion rate of ammonia nitrogen is very fast so that the problem of breeding water body nitrite is the most prominent.
Hydrogen sulfide under anoxic conditions, is decomposed through anaerobic bacteria by the sulfurous organic compound in residual bait or feces and produces, and hydrogen sulfide can be combined formation metal sulfide with the slaine in Sediments, causes blackening at the bottom of pond.
After the nitrite concentration in water runs up to 0.1 mg/litre, the fish of cultivation, shrimp in water body will be produced harm by nitrite. Its mechanism of action, mainly by the Repiration of fish and shrimp, is entered blood by the gill filament, and fish, shrimp erythrocyte number and amount of hemoglobin gradually decrease, and blood oxygen carrying capability lowers gradually, histanoxia occurs. This macrura reevesii, shrimp food ration reduce, and pathological changes, dyspnea, restlessness or bradykinesia occurs in gill tissue, thus causing fish and shrimp anoxia, and even death by suffocation. Nitrite also can react, with secondary amine class, the nitrous acid amine substance generating carcinogenecity, is conducive to inferior ammonium nitrate to be formed when pH value is low. There is fish and shrimp anorexia phenomenon in a lot of ponds, and nitrite is too high is exactly one of the main reasons. The low pH value caused in cultivation fish, shrimp blood of water pH value declines, and weakens its blood oxygen carrying capability, although the dissolved oxygen in water is higher, can cause fish, shrimp physiology anoxia, often raise the nose above water to breathe, and growth retardation or ill. It addition, the pH value in water is too low, the microbial activities in water being caused to be suppressed, Organic substance is not easily decomposed.
In the water of current control pond, the main method of ammonia nitrogen and nitrite is to use special purpose device to remove or chemistry, biological method removal. Chemical method usually adds oxidant such as peroxide complex, in order to oxidation of sulfureted hydrogen, ammonia and nitrite, as Chinese patent CN104556477A discloses the purification technique of a kind of breeding water body, relates to chemical method and purifies. The shortcoming of chemical method is to add a large amount of novel chemical substance at Chi Zhongyou, can increase the weight of the pollution of Chi Shui, serious even result in pond and can not re-use completely. And use special purpose device remove harmful substance, purifying aquaculture pond method also have many reports, pool bottom sludge such as patent CN1164320A processes device, the device etc. integrating nutrient interpolation, pool water treatment of CN1070021C, but these devices are accepted because cost is difficult for raiser, and the defect of the using method of complexity and Operation and Maintenance aspect, actual can not meet the needs of raiser, thus use these devices harmful substance to remove in water almost without aquaculture family. Biological method is to add photosynthetic bacteria, compound probiotic, digestion bacterium, bacillus cereus etc. in pond, to improve the ecological environment in pond. As Chinese patent CN104591482A discloses the aeration treating method of a kind of breeding water body, relate to biological method and improve; And for example Chinese patent CN103539320A discloses a kind of to inorganic salt filter cleaning technique in water quality, wherein also relates to biological method and improves, but is still mainly chemically main in these patented methods.
