preparation example Construction

[0029] The invention provides a method for preparing "artificial capsule" type multifunctional particles, comprising the following steps:

[0030] 1) mixing the pulverized ore, the first binder, the first flocculant, microorganisms and water, and then successively granulating and drying to obtain ore particles;

[0031] 2) After mixing the mineral particles, the second binder and water, then adding the second flocculant to obtain mineral particles-bonding-flocculation structure particles;

[0032] 3) The mineral particle-bonding-flocculation structure particle is mixed with highly efficient degrading bacteria to obtain "artificial capsule" type multifunctional particles.

[0033] In the invention, the crushed ore, the first binder, the first flocculant, microorganisms and water are mixed, and then successively granulated and dried to obtain ore particles. In the present invention, the ore is preferably crushed and sieved to a size of ≤0.85 mm, more preferably 0.4 mm to 0.85 m...

Embodiment 1

[0049] Grind and sieve the zeolite with a particle size of 0.5mm. Weigh 200g of the crushed zeolite, 1.6g of chitosan, 1g of PAC, 0.6g of microbial powder, and 8mL of water. After mixing evenly, granulate, dry, and dry The temperature is 60°C, and spherical ore particles with a diameter of 2 mm are obtained.

[0050] Weigh 200g of spherical mineral particles, 10g of chitosan and 4mL of water and mix them thoroughly to make a layer of chitosan adhere to the surface of the mineral particles, then add 14g of PAC, and fully stir and mix to obtain mineral particles-bonding-flocculation structure particles.

[0051] Weigh 1 g of photosynthetic bacteria, 200 g of mineral particle-bonding-flocculation structure particles, and stir evenly to obtain "artificial capsule" type multifunctional particles.

[0052] Add 200g of "artificial capsule" multifunctional granules into 1L of river water. After the granules are put into the river, aeration and oxygenation are needed to increase the ri...

Embodiment 2

[0077] The medical stone and zeolite were crushed and sieved respectively, the particle size was 0.5 mm, and 40 parts of the crushed medical stone, 35 parts of zeolite, 0.8 part of chitosan, 0.5 part of PAC, 0.3 part of microorganism and 6 parts of water were weighed. After stirring and mixing evenly, granulation and drying are carried out in sequence. The drying temperature is 55° C. to obtain spherical mineral particles with a diameter of 3 mm.

[0078] Weigh 85 parts of mineral particles, 5 parts of chitosan and 4 parts of water, fully stir and mix, so that a layer of chitosan is attached to the surface of the mineral particles, and then add 7 parts of PAC, fully stir and mix to obtain mineral particles-bonding-flocculation Structural particles.

[0079] Weigh 0.5 parts of photosynthetic bacteria and 85 parts of mineral particles-bonding-flocculation structure particles, and stir evenly to obtain "artificial capsule" type multifunctional particles. The purification effect of...

Abstract

The invention provides a preparation method of artificial capsule type multifunctional particles, and belongs to the field of surface water pollution treatment. According to the preparation method, ore is used as a carrier, microorganisms are loaded on the ore by adding a binder and a flocculant, and meanwhile, mineral particles are coated with a binder layer, a flocculant layer and a high-efficiency degrading bacterium layer to form structures similar to bacterial capsules. The capsule structure not only can protect microorganisms in mineral particles, but also has the capability of immobilizing external efficient degrading bacteria. Minerals, a binding-flocculating material and microorganisms in the multifunctional particles coordinate with one another, comprehensive utilization is realized, the advantages of each components are maintained, optimal adjustment is performed according to different pollution characteristics of water body, the floating water purification capacity is effectively improved, the effects of energy conservation, emission reduction and resource utilization are achieved, and the method can be widely applied to pollution treatment of rivers, lakes and reservoirs and has good market application prospects.

Description

technical field [0001] The invention relates to the field of surface water pollution control, in particular to an "artificial capsule" type multifunctional particle and its preparation method and application. Background technique [0002] The commonly used treatment methods in my country are interception method and dredging method, but these two treatment methods have great limitations, not only consume high costs, but also cannot solve the pollution problems of rivers, lakes and reservoirs once and for all. At present, the in-situ direct purification method of river and lake water is widely used in the world, immersing suitable fillers into the water body, and properly aerating and oxygenating. The consumption cost is lower than the previous two types, not only can effectively reduce water pollution, but also the purification effect lasts for a long time. [0003] Chinese invention patent 201611167230.2 discloses a sewage degreasing granule preparation and its preparation ...
