Problems solved by technology

Among them, organic carriers such as PVC, PE, and PP have strong biodegradability resistance, but are poor in biocompatibility and mass transfer; while the currently used inorganic carriers are mostly granular carriers. , such as limestone, ceramics, etc.
Despite their mechanical strength and biocompatibility, they are heavy, complex to operate, and difficult to recycle

Embodiment example 1

[0021] Cut basalt fiber bundles with a length of 20cm and 1000 basalt fibers in each bundle, and arrange them in a spiral order with a size of 6mm 2 on the insulation layer of the single-core cable. The production method is as follows: the basalt fiber bundle is sandwiched in the middle of the double-folded single-core cable through manual twisting until the length of the unit carrier bundle is 50cm.

Embodiment example 2

[0023] Cut basalt fiber bundles with a length of 25cm and 800 basalt fibers each, and arrange them in a spiral order with a size of 4mm 2 on the insulation layer of the single-core cable. The production method is as follows: the basalt fiber bundle is sandwiched in the middle of the double-folded single-core cable through manual twisting, until the length of the unit carrier bundle is 60cm.

Embodiment example 3

[0025] Cut basalt fiber bundles with a length of 30cm and 600 basalt fibers each, and arrange them in a spiral order with a size of 2.5mm 2 on the insulation layer of the single-core cable. The production method is as follows: the basalt fiber bundle is sandwiched in the middle of the double-folded single-core cable through manual twisting, until the length of the unit carrier bundle is 70cm.

Abstract

The invention belongs to the field of water body purification, and in particular discloses a carrier for microbial purification of a water body and a manufacturing method of the carrier. The carrier for microbial purification of the water body consists of a central rope formed by twisting folded single-core cable lines and basalt fiber bundles which are spirally arranged along the outer side of an insulating layer of each single-core cable line in sequence, wherein the basalt fiber bundles are twisted and clamped into the two folded single-core cable lines. The carrier for microbial purification of the water body, disclosed by the invention, has the characteristics of large tensile strength, no filament looseness, easily-expanded filaments, uniform distribution, large specific surface area, long service life and the like, and can be widely applied to a biological treatment process of wastewater.

Description

technical field [0001] The invention belongs to the field of water body purification, and relates to a carrier for microbial purification of water body and a production method thereof, in particular to a carrier for microbial purification with basalt fiber as a base material and a production method thereof. Background technique [0002] Biological contact oxidation is a commonly used water purification process. By adding biological carriers, the method allows microorganisms to attach and grow on the surface of the carrier to form a biofilm. After the sewage is in contact with the biofilm, the pollutants are adsorbed and transformed by the microorganisms, thereby purifying sewage. Due to the addition of biological carriers, microorganisms are fixed on the solid surface, and even microorganisms with a slow proliferation rate can grow and reproduce. Therefore, the biological phase in the biofilm is relatively rich, and there are microorganisms with the same high trophic level, ...
