Method for preparing water quality modifying microecological preparation for reducing ammonia nitrogen and nitrite nitrogen

Abstract

The invention relates to a method for preparing a water quality modifying microecological preparation for reducing ammonia nitrogen and nitrite nitrogen, and belongs to the technical field of aquiculture technology and ecological environmental protection. The microecological is prepared by the following steps: mixing Bacillus foecalis alkaligenes CGMCC NO.1.1786 and arthrobacterium CGMCC NO.1282 into mixed bacteria; performing fermentation on the mixed bacteria for 24 to 36 hours in a culture medium in a fermenter at the fermentation temperature of between 28 and 32 DEG C; processing the obtained product into a liquid preparation through filling or continuous dilution or concentration after fermentation culture; and preparing the water quality modifying microecological preparation with the functions of reducing the ammonia nitrogen and the nitrite nitrogen in a water body. The preparation is convenient to use, is slightly influenced by environmental conditions, has small dosage, can obviously reduce the content of the ammonia nitrogen and the nitrite nitrogen in a pool water body after use, maintains the effect for 10 to 15 days, can effectively prevent diseases and paroxysmal death of aquaculture organisms and improve the yield and the quality of the aquaculture organisms when simultaneously improving the environmental quality of the pool water quality and the survival conditions of the aquaculture organisms.

Description

technical field [0001] The invention discloses a preparation method of a water quality improvement micro-ecological preparation for reducing ammonia nitrogen and nitrite nitrogen, relates to a water quality improvement product for reducing ammonia nitrogen and nitrite nitrogen, and belongs to the technical fields of aquaculture technology and ecological environment protection. Background technique [0002] With the adjustment of rural industrial structure, my country's aquaculture industry has developed by leaps and bounds. In order to increase the aquaculture output per unit of water body, one-sided pursuit of high yield, often excessively increase the stocking density, excessive baiting, and fertilization, resulting in a sharp increase in organic matter, nitrogen, and phosphorus in the water, a large number of algal blooms, a decrease in water transparency, and deterioration of water quality. Excessive decomposition of organic matter in the water not only consumes dissolve...

Problems solved by technology

[0003] On the other hand, my country is a country with a shortage of water resources, and the temporal and spatial distribution of water resources is very uneven. With the development of society, the amount of available water resources is decreasing year by year; at the same time, the use efficiency of water resources is not high and waste is particularly common. What is more serious is that the pollution of water resources has not been effectively solved

However, the current nitrifying bacteria products in the field of water quality improvement have more or less problems

First of all, the nitrifying bacteria products of a single strain cannot reduce the concentration of ammonia nitrogen and nitrite nitrogen at the same time: for example, some strains have a removal rate of more than 80% for ammonia nitrogen, but at the same time they will produce a large amount of nitrite, while nitrite The harm of salt to farmed animals in aquaculture ponds is far greater than that of ammonia; in addition, some strains can effectively remove nitrite nitrogen, but the removal effect on ammonia nitrogen is not obvious, so the harm of nitrite cannot be fundamentally removed, because ammonia nitrogen The oxidation product is nitrite nitrogen; secondly, even if it is a compound product of several nitrifying bacteria, due to the unsatisfactory compound ratio or the limitation of culture conditions, these products often cannot give full play to the role of different bacteria in reducing ammonia nitrogen and nitrite nitrogen. effect
