Embodiment 1

[0025] The felt-like nylon material was rinsed with water to remove contaminants such as dust and dried; then, it was cleaned with acetone for degreasing treatment; then, the felt-like nylon material was immersed in a water-soluble phenolic resin (solid content of 25wt%), taken out and passed through The excess binder is squeezed out by the double rollers, and then the powdered activated carbon with a specific surface area of ​​1200 square meters / g is evenly distributed on the felt-like nylon material, and the load is 0.1 g / square centimeter. Compression is carried out, and then a curing reaction is carried out to firmly support the activated carbon on the felt-like nylon material, and then cut into a specific size of the activated carbon-loaded felt-like nylon biocarrier according to the requirements.

[0026] The above-mentioned modified carrier was put into a biofilm reactor for the start-up test of film formation (the volume of the reactor was 4 liters, the aeration rate wa...

Embodiment 2

[0028] The felt-like nylon material was rinsed with water to remove contaminants such as dust, and dried; then, it was cleaned with acetone for degreasing treatment; then, the felt-like nylon material was immersed in water-soluble phenolic resin (solid content of 25wt%), taken out and passed through double The roller squeezes out the excess binder, and then the powdered activated carbon with a specific surface area of ​​600 square meters / g is evenly distributed on the felt-like nylon material, and further pressed by double rollers, and then the curing reaction is carried out. The activated carbon is firmly loaded on the felt-like nylon material, and the loading amount is 0.1 g / cm 2 , and then according to the requirements, it is cut into a felt-like nylon biocarrier loaded with activated carbon of a specific size.

Embodiment 3

[0031]The felt-like nylon material was rinsed with water to remove contaminants such as dust, and dried; then, it was cleaned with acetone for degreasing treatment; then, the felt-like nylon material was immersed in water-soluble phenolic resin (solid content of 25wt%), taken out and passed through double The roller squeezes out the excess binder, and then the powdered activated carbon with a specific surface area of ​​2000 square meters / g is evenly distributed on the felt-like nylon material, which is further pressed by double rollers, and then subjected to a curing reaction. The activated carbon is firmly loaded on the felt-like nylon material, and the loading amount is 0.1 g / cm 2 , and then according to the requirements, it is cut into a felt-like nylon biocarrier loaded with activated carbon of a specific size.

Abstract

The invention relates to an active carbon supported felted nylon biocarrier, and a preparation method and an application thereof, and belongs to the technical filed of water treatment microorganism carriers. Active carbon is uniformly bonded to the surface of a felted nylon material through a binder, or / and is bonded in the pore structure of the felted nylon material in an inlay manner, and the felted nylon material has a planar surface and has a netted porous structure. The preparation method comprises the following steps: preprocessing the felted nylon material; dipping the processed felted nylon material in a binder; and uniformly loading the active carbon onto the binder dipped felted nylon material in order to form the active carbon supported felted nylon biocarrier. The active carbon supported felted nylon biocarrier can be used in sewage treatment as a microorganism carrier.

Description

technical field [0001] The invention belongs to the technical field of water treatment microbial carriers, in particular to a felt-like nylon biological carrier loaded with activated carbon, a preparation method and an application. technical background [0002] Water pollution is becoming more and more serious, the degree of pollution is deepening, the composition of pollutants is complex, the difference is large, the types are many, and the concentration is high. In order to ensure sustainable development and to ensure the continuous improvement of the quality of work and life, the requirements for sewage treatment are becoming more and more strict, and the standards are getting higher and higher. [0003] Biological method is one of the most effective methods of sewage treatment and has been widely adopted, and carrier is the core of biological method. The performance of the carrier is directly related to the sewage treatment effect of the biological method. The carrier ...
