Subtilis in the described composite fungus agent is a gram-positive microorganism, and 0.6～0.9 * 1.0～1.5 microns of gemma are oval to column, are positioned at thalline central authorities or inclined to one side slightly, and gemma forms the back thalline and do not expand.The bacterium colony surface irregularity is opaque, dirty white or little yellow, and when growing in the liquid medium within, the normal wrinkle mould that forms.Aerophil.Available protein, multiple sugar and starch decompose tryptophane and form indoles.The subtilyne that produces in the subtilis thalli growth process, polymyxin, nystatin, linear gramicidins isoreactivity material, these active substances have the obvious suppression effect to the conditioned pathogen of pathogenic bacterium or autogenous infection; Subtilis consumes the free oxygen in the environment rapidly, promotes the anerobe growth, and produces organic acid such as lactic acid, reduces environment pH value, suppresses other pathogenic bacterium indirectly and grows.
Nitrobacteria in the described composite fungus agent is a kind of aerobic bacteria, can grow in the water of aerobic or in the layer of sand, and playing the part of very important role in nitrogen cycle purification of water quality process.They comprise a kind of bacillus, coccus or the spirobacteria of form inequality type.Belong to the class of property bacterium on one's own account, comprise two kinds of complete different metabolic groups: nitrous acid Pseudomonas and nitric acid Pseudomonas.Nitrite bacteria (claiming ammonia oxidation bacteria again) becomes nitrous acid with ammonia oxidation.Nitrate bacteria (claiming nitrobacteria again) is oxidized to nitric acid with nitrous acid.This two classes bacterium can obtain the growth energy needed respectively from above oxidising process, and ammonia in the soil or ammonium salt must just can change nitrate under the acting in conjunction of above two bacterioids.Nitrobacteria has vital role in the nature Nitrogen Cycling.
The carbohydrate that milk-acid bacteria in the described composite fungus agent obtains with photosynthetic bacterium, yeast is a matrix, produces lactic acid.Because milk-acid bacteria has very strong sterilizing power, particularly suppress the harmful microbe breeding, and organic rapid corrupt the decomposition; Milk-acid bacteria can make the difficult organism that decomposes such as xylogen, Mierocrystalline cellulose decompose.
Yeast in the described composite fungus agent can both be grown in the environment of aerobic and anaerobic, and promptly yeast is a facultative anaerobe, and under the anoxybiotic situation, yeast becomes alcohol and carbonic acid gas to sugar decomposition.Under the situation of aerobic, it becomes carbonic acid gas and water to sugar decomposition, and when aerobic existed, the yeast growth was very fast.
The purifying method of polluted river of the present invention is thrown in the composite fungus agent that photosynthetic bacterium, subtilis, nitrifier, yeast, milk-acid bacteria etc. are formed in a large number, can about 30 days, realize that the preliminary change of water body is clear, color shoals, stink weakens, the water pollution index reduces like this.This stage mainly concentrates on water body (not containing bed mud), after a large amount of complex-probiotic groups are rendered in the water body, become the beneficial non-hibernating eggs group who has significant advantage in the water body very soon, organic pollutant in very fast transfer, conversion and the degraded water body realizes that the preliminary change of water body is clear, colourity shoals, stink weakens, the water pollution index reduces.
