Biological sediment modifier for fishpond

Abstract

The invention discloses a biological sediment modifier for a fishpond, belonging to the technical field of water quality purification of fishponds. The biological sediment modifier is prepared from the following raw materials in parts by weight: 3-8 parts of bacillus subtilis powder, 3-8 parts of nitrifying bacteria powder, 3-8 parts of denitrifying bacteria powder, 3-8 parts of sulfurizing bacteria powder, 10-40 parts of zeolite powder, 40-70 parts of sodium humate, and 0.5-3 parts of calcium peroxide, wherein the total content of viable bacteria is 2*10<8>-2*10<9> per gram. The biological sediment modifier disclosed by the invention can be used for absorbing the nutrition of sediment, and forming a bacterium membrane on the sediment via fermentation, breeding and bacterial community expansion, so as to cover the sediment and prevent the sediment from polluting water quality, thus benefiting the growth of aquatic animals, greatly increasing a degradation rate, and avoiding the secondary pollution of chemical degradation to a water body.

Description

technical field [0001] The invention relates to the technical field of fishpond water purification. Background technique [0002] Fish farming starts with water, and good water raises good fish. With the improvement of intensive aquaculture, water quality is deteriorating and difficult diseases are increasing. Water quality management has become the most concerned issue of farmers. With the growth of the breeding period, there are more and more organic matter in the pond. As the water temperature rises, baiting is continued throughout the process, the fish continue to eat and excrete, and the algae in the water continue to grow and die. The breeding density is too high, causing excessive feeding, a large amount of residual bait, feces, and excrement are diffused and dissolved in the water and deposited on the bottom of the water. Excess feed, fish and shrimp excrement, dead algae, and the corpses of other animals and plants, etc. Accumulate in the water, and the breeding go...

Problems solved by technology

However, although the harmful substances in the water body are reduced, the harmful substances flocculated to the bottom of the pool cannot be removed. If this water purifier is used repeatedly for a long time, it will also cause secondary pollution of the water body by its own metal substances and chemical substances. , so its function can only alleviate the pollution of the water body, but cannot fundamentally remove the pollution

Biological water purifiers can remove ammonia nitrogen and nitrite in water to a certain extent, and improve water pollution. Therefore, the use of microbial agents to control water pollution has attracted widespread attention. However, the existing biological water purifiers have a problem of low degradation rate.
