Embodiment 1

[0017] Embodiment 1: a kind of its preparation method of animal origin flocculant comprises the following steps:

[0018] S1: Take a number of gastropods and place them on a vibrating sieve, perform vibration stimulation on the gastropods, and collect the mucus secreted by the gastropods;

[0019] S2: Heat the mucus collected in S1 in a water bath at 60°C and keep it warm for 30 minutes;

[0020] S3: performing dialysis treatment on the raw material treated in S2 to obtain a purified solution;

[0021] S4: Spray-drying the purified liquid to obtain the animal-derived flocculant.

[0022] The gastropods are one or more of white jade snails, apple snails and round snails. In the S1, the gastropod needs to be cleaned before the vibration stimulation treatment to clean the surface sediment. The dialysis treatment in S3 is dialysis using a hollow fiber dialyzer with a molecular weight cut off of 8000. The vibration stimulation time is 30min.

Embodiment 2

[0023] Embodiment 2: A method for preparing an animal-derived flocculant, comprising the following steps:

[0024] S1: Take a number of gastropods and place them on a vibrating sieve, perform vibration stimulation on the gastropods, and collect the mucus secreted by the gastropods;

[0025] S2: Heat the mucus collected in S1 in a water bath at 60°C and keep it warm for 30 minutes;

[0026] S3: performing dialysis treatment on the raw material treated in S2 to obtain a purified solution;

[0027] S4: Spray-drying the purified liquid to obtain the animal-derived flocculant.

[0028] The gastropods are one or more of white jade snails, apple snails and round snails. In the S1, the gastropod needs to be cleaned before the vibration stimulation treatment to clean the surface sediment. The dialysis treatment in S3 is dialysis using a hollow fiber dialyzer with a molecular weight cut off of 14,000. The vibration stimulation time is 40min.

Embodiment 3

[0029] Embodiment three: a kind of its preparation method of animal origin flocculant, comprises the following steps:

[0030] S1: Take a number of gastropods and place them on a vibrating sieve, perform vibration stimulation on the gastropods, and collect the mucus secreted by the gastropods;

[0031] S2: Heat the mucus collected in S1 in a water bath at 60°C and keep it warm for 30 minutes;

[0032] S3: performing dialysis treatment on the raw material treated in S2 to obtain a purified solution;

[0033] S4: Spray-drying the purified liquid to obtain the animal-derived flocculant.

[0034] The gastropods are one or more of white jade snails, apple snails and round snails. In the S1, the gastropod needs to be cleaned before the vibration stimulation treatment to clean the surface sediment. The dialysis treatment in S3 is dialysis using a hollow fiber dialyzer with a molecular weight cut off of 11,000. The vibration stimulation time is 50min.

Abstract

The invention discloses an animal-derived flocculant. The animal-derived flocculant is prepared by extracting high-molecular glycoprotein from mucus secreted by gastropod animals. The preparation method comprises the following steps: S1, placing a plurality of gastropods on a vibrating screen, carrying out vibration stimulation treatment on the gastropods, and collecting mucus secreted by the gastropods; s2, heating the mucus collected in the S1 in a water bath at 60 DEG C, and keeping the temperature for 30 minutes; s3, performing dialysis treatment on the raw materials treated in the S2 to obtain purified liquid; and S4, carrying out spray drying treatment on the purified liquid to obtain the animal-derived flocculant. The animal-derived flocculant provided by the invention has the advantages that flocculate generated by the animal-derived flocculant provided by the invention is small in dehydration difficulty, low in secondary treatment cost, biodegradable and not easy to generate secondary pollution. The gastropod used in the preparation method of the animal-derived flocculant provided by the invention is low in price, low in breeding cost and convenient to extract, so that the animal-derived flocculant is low in production cost.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an animal source flocculant and a preparation method thereof. Background technique [0002] In the field of water treatment, there are three methods to reduce the concentration of suspended solids in the water body and improve the transparency of the water body: filtration, sedimentation, and adding flocculants. Among them, the flocculants commonly used for adding flocculants include polyferric salt, polyaluminum Acrylamide, microbial flocculant, etc. Among them, polyferric salt, polyaluminum salt, and polyacrylamide have mature technologies and are widely used, but the dehydration of flocs produced by them is difficult, the cost of secondary treatment is high, and improper treatment will cause secondary pollution; microbial flocculant technology is not yet mature , high price and low production capacity. Therefore, it is urgent to study an animal-derived flocculant and its prepa...
