Embodiment 1

[0052] Example 1: Preparation of decomposed straw

[0053] 1. Main raw materials

[0054] 1. The first microbial agent, by weight ratio:

[0055]

[0056] The requirements for the prepared compound bacteria: acid protease≥2000u / g, neutral protease≥10000u / g, cellulase≥10000u / g, and the insufficient part is added to the corresponding enzyme preparation.

[0057] Bacillus subtilis KX-1 can survive and reproduce at 2~8℃.

[0058] 2. Volcanic rock biologics

[0059] Volcanic rock biologics use the porous and large surface area of ​​volcanic rock. It contains a large amount of silicon, potassium, sodium, iron, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt and other dozens of minerals. And trace elements, as well as the chelating properties of heavy metals, using it as a carrier, implanted a variety of beneficial microbial flora (including actinomycetes, bacillus and other beneficial microorganisms) that have been verified to be harmless to humans, animals an...

Embodiment 2

[0122] Example 2: Preparation of biological flocs

[0123] The preparation of biological flocs includes the following steps:

[0124] (1) The decomposed straw prepared according to the method of Example 1 is crushed into about 80 mesh with a pulverizer to obtain the decomposed straw powder;

[0125] (2) Add 200 grams of the first microbial inoculum per kilogram of decomposed straw powder. Add the first microbial inoculum to the decomposed straw powder, and then spray nitrifying bacteria and denitrifying bacteria in sequence. The amount of nitrifying bacteria and denitrifying bacteria added is 100ml For every kilogram of decomposed straw powder, biological flocs are obtained.

[0126] For pictures of the resulting biological flocs, see Figure 5 .

[0127] The organic indicators of the biological flocs obtained in this example and the biological flocs of a foreign company were tested. The results are shown in Table 4. In addition, the trace elements of the biological flocs of this exam...

Embodiment 3

[0132] Example 3: Application of biological flocs to river sewage purification treatment test

[0133] Test water: Kunshan Tianrui Environmental Company No. 10 River Dam (dissolved oxygen 0.62mg / L ammonia nitrogen 14.9mg / L)

[0134] Water sample: 2L

[0135] Test: Two tests were carried out successively, and the results are shown in Table 6 and Table 7 respectively.

[0136] Table 6

[0137]

[0138] Table 7

[0139]

[0140] Note:

[0141] 1. In each test, the same river water is taken, 2000ml per unit.

[0142] 2. The water temperature is the same as the outdoor water temperature.

[0143] 3. The aeration rate is the same for each test.

[0144] 4. In the test, Shuibiqing was used as a control treatment agent, which was mainly composed of several low-temperature bacteria described in the present invention.

Abstract

The invention relates to a bio-floccule, a preparation method thereof, and an application thereof in aquaculture, water purification, industrial water treatment, and soil repairing and improvement. The bio-floccule includes decayed straw powder, a first microbial agent, nitrifying bacteria and denitrifying bacteria. The first microbial agent includes bacillus subtilis and optional actinomycetes. The preparation method includes the following steps: adding the microbial agent and then adding the nitrifying bacteria and denitrifying bacteria successively to the decayed straw powder. The bio-floccule is prepared with the decayed straw powder as a main body and by addition of the special microbial agent, nitrifying bacteria and denitrifying bacteria. The main technical indices of the bio-floccule reach and even are better than foreign bio-floccules in the same type. In addition, a test proves that the bio-floccule has excellent purifying effects on sewage in river channels.

Description

Technical field [0001] The invention relates to a biological floc and a preparation method thereof. Biological flocs are suitable for the treatment of water pollution and the purification of liquid emissions from aquaculture and other farms. It is also suitable for soil remediation, saline soil improvement, and industrial water purification. Background technique [0002] The concept of biological flocs appeared in the field of aquaculture. The biological flocs in aquaculture refer to the organisms and inorganic substances with aerobic microorganisms as the main body in the aquaculture water. The aggregates formed by biological flocculation are mostly composed of bacteria, phytoplankton, organic debris and some inorganic substances. Flocculation composition. Nowadays, Bio-floc Technology (technology, BFT) is to feed a large amount of bait to the aquaculture water body to supplement the organic carbon material, so that the water body maintains a certain carbon to nitrogen ratio, ...
