Abstract
The invention relates to a method for treating breeding water by composite bacteria. The invention adopts the technical proposal that: 1.5 to 3.0 percent of the composite bacteria accounting for the total weight of the breeding water is thrown into the breeding water every three days, wherein the composite bacteria is mixed bacteria of photosynthetic bacteria and streptococcus faecalis according to a weight ratio of 1:0.5-1.5. The method has low cost and stable action effect, and can effectively improve the water quality of the breeding water, enhance the resistance capability of aquatic organism, and improve the survival rate of the aquatic organism.
Description
Technical field
The present invention relates to a kind of treatment process of culturing water, relate to a kind of method that adopts treating breeding water by composite bacteria particularly.
Background technology
The principle of water quality microbiological manipulation technology is to become harmless material by injurious factor in the microbiological degradation water, and self can utilize the energy that produces in the decomposition to grow.
Before the seventies in 20th century, because antibiotic appearance, it is definite that success that germ-free animal is raised and anerobe have comparative advantage in enteron aisle etc., and all research has played great promoter action to microecology, thereby has excited the development of probiotics.Probiotics removes the aspects such as production that have been applied to people doctor, animal and veterinary, little ecological beverage, makeup, also is widely used in aquaculture.The bacterial classification that is usually used in animal microecological formulation has enteron aisle dominant bacterias such as lactobacillus, genus bifidobacterium, bacillus, streptococcus, Saccharomycodes.It is reported that Japanese using Bacillus subtilis carries out decomposing, purifying to the mud of seabed stores, fishpond and the reservoir of breeding fish, receive apparent effect; Shrimp pond substrate and water quality environment are improved in South East Asia and China Taiwan using microbe; Thereby the China mainland area also has report to use effective microorganism preparation decomposes organic bed mud promotion fish growth.
Up to the present, in aquaculture, mostly adopt single microorganism bacterial classification (as photosynthetic bacterium or nitrobacteria) to control and purify water, but all have certain limitation: subject range is narrow, action effect instability etc., as independent employing photosynthetic bacterium control water quality, the control DeGrain of total phosphorus, the water quality eutrophication is not controlled effectively, COD may command instability, occur sometimes significantly changing, influence hydrobiological existence, even can cause hydrobiological death among a small circle, the hydrobiont survival rate is reduced.On the existing market also by the mixed bacterium preparation of forming by photosynthetic bacterium, pseudomonas, genus bacillus, nitrifier and denitrifying bacteria etc., but the cost height, price is expensive.
Summary of the invention
In order to address the above problem, the invention provides that a kind of cost is low, action effect is stable, effectively improve the water quality of culturing water, strengthen hydrobiological resistivity, improves the method for the treating breeding water by composite bacteria of hydrobiont survival rate.
To achieve these goals, the technical solution used in the present invention is: in culturing water, added the composite bacteria of culturing water gross weight 1.5%～3.0% every 3 days, wherein said composite bacteria is photosynthetic bacterium and streptococcus faecium by weight 1: 0.5～1.5 mixed bacterium.
The present invention mainly uses the synergistic effect of photosynthetic bacterium and streptococcus faecium.Among the present invention, streptococcus faecium produces acid, reduce the pH in the water, water quality is had be more suitable for the condition of photosynthetic bacterium growth, and good performance is arranged photosynthetic bacterium aspect the reduction ammonia nitrogen, streptococcus faecium is then having good effect aspect the reduction of total phosphorus, thereby composite bacteria has reached a more comprehensive degradation effect.
The invention has the beneficial effects as follows:
1, COD control effect stability.
Culture cultured fishes in the water, in culturing water, add photosynthetic bacterium, streptococcus faecium and composite bacteria respectively separately, from Fig. 1 as seen, photosynthetic bacterium and composite bacteria all can reduce the COD value at short notice, and the water body COD that adds composite bacteria maintains about 100mg/l basically, but obviously stable than adding photosynthetic bacterium separately.As seen add composite bacteria breed water was purified in the very fast time, and the COD level of control water quality that can be more stable.
2, ammonia nitrogen control is effective.
Culture cultured fishes in the water, in culturing water, add photosynthetic bacterium, streptococcus faecium and composite bacteria respectively separately, from Fig. 2 as seen, the breed water ammonia nitrogen concentration difference of three kinds of dosing methods is not obvious, increases along with fish are excremental, and the ammonia nitrogen value all slowly raises, but the water body ammonia nitrogen value that adds composite bacteria maintains in the scope of 0.55～0.65mg/l, suitable fish growth.
3, the controllability of total phosphorus is outstanding.
Culture cultured fishes in the water, in culturing water, add photosynthetic bacterium, streptococcus faecium and composite bacteria respectively separately, from Fig. 3 as seen, to the removal of total phosphorus, composite bacteria can maintain about 0.8～1.0mg/l, and the control effect of total phosphorus is obvious.
4, the common culture effect of two bacterium is good.
Photosynthetic bacterium and streptococcus faecium are facultative anaerobe, and culture condition substantially all is 30 ℃ also, about pH=7.0, thereby are convenient to cultivate, and can make the thalline raised growth.
Through the breed water that method of the present invention is handled, water quality can reach: COD concentration is 80～120mg/L, and ammonia nitrogen is 0.55～0.65mg/L, and DO is 6.5 ± 0.2mg/L, and total phosphorus is 0.8～1.2mg/l.Suitable hydrobiological existence.In addition, streptococcus faecium has some improvement to hydrobiological intestinal environment tool, thereby can strengthen its resistivity, improves hydrobiological survival rate.
Method of the present invention is to culturing water, and the decontamination effect improving of water quality improves more than 40% than the effect of photosynthetic bacterium individual curing.
