example 1

[0045]Example 1 Obtaining of a kind of compound probiotics for purifying water:

[0046] 1. Cultivation of various components of multifunctional beneficial bacteria:

[0047] Rhodobacter sphaeroide ATCC 17023, Saccharomyces cerevisiae CICC 1964, Lactobacillus bulgaricus, L.b ATCC 11842, Bacillus subtilis CICC23659, Streptomyces griseus 10CC respectively According to the above-mentioned corresponding culture medium and culture conditions, respectively expand to 1500L fermenter and carry out liquid fermentation culture.

[0048] 2. Obtaining multifunctional beneficial bacteria mixture:

[0049] After the fermentation is finished, use 0.2μ microfiltration membrane to concentrate, and stop the concentration when the number of viable bacteria is ≥ 50 billion / g, and obtain 110L of Rhodobacter sphaericum concentrate, 91L of brewer's yeast concentrate, 157L of Lactobacillus bulgaricus concentrate, and Bacillus subtilis concentrate Bacillus concentrate 163L, Streptomyces griseus conc...

example 2

[0052] The activity analysis of example 2 compound probiotics:

[0053] Take 10 grams of the compound probiotics, and carry out routine counting of live bacteria. The results show that the number of live bacteria of various bacteria is more than 5 billion per gram, which is obviously better than that of similar products currently on the market, and the survival rate after one year is more than 80%.

example 3

[0054] Example 3 Application test (1)

[0055] 1. Subjects of the test: 7 cubic glass jars of 55×35×60cm (length×width×height), divided into 3 groups. No. 1 is the blank group, No. 2-4 is the control group, and No. 5-7 is the experimental group. In order to be closer to the conditions of the pond, the surroundings of the tank were covered with black cloth, and the black and odorous sludge at the bottom of the lake was taken and spread 8 cm in the tank. Put it in an open place outdoors, and randomly place it under natural conditions. The test water is taken from Taihu Lake in Wuxi, and the water in each tank is filled to a height of 50cm, and the test is performed after standing for 24 hours.

[0056] 2. Test method: No. 1 is blank, without adding any substance; No. 2-4 is added with a similar product of a certain brand on the market; No. 5-7 is added with the product of the present invention, and the addition amount is 3g / m 2 , Detect and record the dissolved oxygen, ammoni...

Abstract

The invention relates to compound microecologics for purifying water quality and a preparation method thereof, belonging to the technical field of applied biotechnology. The method is characterized by conforming to the principle of diversified development of microecologics, utilizing various kinds of beneficial bacteria with different functions, carrying out scientific combination according to the proportion occupied by each kind of bacteria determined by orthogonal experiment, and forming efficient the multifunctional compound microecologics with the functions of intestine environment improvement, eating promotion, harmful bacteria restriction, water quality improvement, and the like. The invention is more characterized in that beneficial bacteria in the invention can be obtained easily at various parent strain markets, liquid fermentation technology is adopted for enlarging culture, and viable breeding accelerator, protective agent, viable absorbent, and the like are added to ensure the stability and the high efficiency of the compound microecologics. The invention solves the problems of unstable product characteristics, unsatisfactory using effect, low viable bacteria survival rate, and the like of microecologics at the current market.

Description

technical field [0001] The invention relates to a compound microecological preparation for purifying water and a processing method thereof, belonging to the field of applied biotechnology. Background technique [0002] Water quality factors have a significant impact on the success or failure of breeding and production. Under normal circumstances, under the action of beneficial bacteria in the water body, the nitrogen cycle is in a stable state, and the ammonia nitrogen and nitrite nitrogen in the water maintain normal levels. However, with the rapid development of the aquaculture industry, the scale of intensive high-density farming is increasing day by day, resulting in a large increase in residual bait and animal excrement in the water body. At the same time, the discharge of untreated aquaculture wastewater and industrial and domestic sewage has seriously polluted the water body and destroyed the aquaculture ecological environment, resulting in an increase in the variety...
