Embodiment 1

[0066] The present embodiment provides a powdery activated carbon carrier (PAC), its moisture content=2.9%, its ash content=12%, its iodine value=984mg / L, its specific surface area=852m 2 / g, its bulk density is 0.57g / cm 3 , its pH value is 8.1, and the mass of activated carbon particles with a particle size of > 200 mesh is ≥ 90%.

[0067] Compound PAC with COD degrading bacteria, the specific process is:

[0068] Slowly add 1 kg of PAC into a container filled with 5 kg of COD-degrading bacteria (bacteria solution) to obtain a mixed solution. The COD-degrading bacteria used in this example are from Pro Biotech (Shanghai) Co., Ltd. Next, put the above mixed solution on a mechanical stirring table, set the stirring speed to 200rpm, and the stirring temperature to 25°C, and fully stir for 48 hours to mix the COD-degrading bacteria solution and PAC evenly, and then seal and store it for later use (that is, to obtain a COD-degraded The powdery activated carbon carrier of bacteri...

Abstract

The invention belongs to the technical field of sewage treatment and provides a powdery activated carbon carrier and a preparation method and application thereof. The mass percent of water in the powdered activated carbon carrier is 2.8-3.0%; the mass percent of the ash content is 11.8%-12.2%; the iodine value is 954-984 mg / L; the specific surface area is 850-855 m <2> / g; the stacking density is 0.54-0.59 g / cm <3>; the pH value is 6.8-8.5; and the mass of the activated carbon particles with the particle size of 200-325 meshes in the powdery activated carbon carrier is greater than or equal to80%. The powdered activated carbon carrier can be directly added, and is simple to operate, long in service life, low in price and wide in application range; the powdery activated carbon carrier is large in specific surface area, so that the number of immobilized microorganisms is larger, and when the powdery activated carbon carrier carrying COD degrading bacteria is added into wastewater with high COD content, an excellent treatment effect is obtained.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a powdered activated carbon carrier, a preparation method of the powdered activated carbon carrier, and an application of the powdered activated carbon carrier in sewage treatment. Background technique [0002] With the rapid development of economy and society, a large amount of domestic and production wastewater is produced every day. If it is not treated in time, it will directly or indirectly endanger the environment and human health. At present, there are physical, chemical and biological treatment technologies for wastewater treatment. Among them, sewage biological treatment technology has gradually become the core technology in the field of sewage treatment due to its safety and economical characteristics, and is favored by sewage treatment engineers. [0003] Biological treatment technology is a method of using specific microbial strains to decompose,...
