Problems solved by technology

There are many powders with extremely small particle size and large specific surface area in the natural environment, which are very suitable for microorganisms to attach, resulting in an increase in the concentration of microorganisms and increasing their sedimentation capacity. The sludge quality of sewage treatment plants cannot be improved, and the quality of effluent water cannot be improved, etc. defect

Embodiment 1

[0025] A biological carrier for enhanced waste water treatment, comprising the following components: 50 parts of zeolite, 35 parts of quartz sand, 8 parts of medical stone, and 10 parts of diatomite.

[0026] The preparation method of the biological carrier is as follows:

[0027] (1) The following ingredients are weighed in parts by weight: 50 parts of zeolite, 35 parts of quartz sand, 8 parts of medical stone, and 10 parts of diatomite;

[0028] (2) After mixing zeolite, quartz sand, medical stone, and diatomaceous earth, add them to a crusher for pulverization, and then pass through a 200-mesh sieve to obtain a powder mixture;

[0029] (3) Add an appropriate amount of recycled reclaimed water to the powder mixture, and dissolve the screened powder carrier by stirring to make a slurry, so that the screened powder carrier can completely absorb moisture and no longer agglomerate and float up, and the soaked powder carrier can be obtained powder slurry;

[0030] (4) Adjust th...

Embodiment 2

[0034] A biological carrier for strengthening waste water treatment, which comprises the following components: 55 parts of diatomite, 15 parts of bentonite, 8 parts of attapulgite and 30 parts of activated carbon.

[0035] The preparation method of the biological carrier was the same as that of Example 1, and its pH was finally adjusted to 7.2.

[0036] In the application process step (3) of the biological carrier, the final concentration of the biological carrier dry powder organism is 8g / L, and the treatment time is 6 hours; the remaining operations are the same as in Example 1.

Embodiment 3

[0038] A biological carrier for strengthening waste water treatment, which comprises the following components: 50 parts of diatomite, 9 parts of fly ash, 10 parts of dolomite, and 30 parts of illite.

[0039] The preparation method of the biocarrier was the same as in Example 1, and its pH was finally adjusted to 7.

[0040] In the application process step (3) of the biological carrier, the final concentration of the biological carrier dry powder organism is 10g / L, and the treatment time is 6 hours; the remaining operations are the same as in Example 1.

Abstract

The invention discloses a biological carrier for strengthening wastewater treatment, a preparation method and application thereof, and belongs to the technical field of environmental functional materials and sewage treatment. The biological carrier comprises any four or more of: 10-70 parts of diatomite, 10-30 parts of bentonite, 5-9 parts of attapulgite, 30-40 parts of montmorillonite, 9-14 parts of fly ash, 4-9 parts of medical stone, 20-35 parts of activated carbon, 5-10 parts of dolomite, 3-8 parts of volcanic ash, 9-15 parts of sepiolite, 30-40 parts of illite, 5-10 parts of kaolin, 40-70 parts of zeolite and 35-45 parts of quartz sand. The volume load of wastewater biological treatment is increased, so that the microbial concentration of biological flocs in biochemical water treatment is remarkably increased, meanwhile, the removal rate of refractory organic matters or TOC is increased, the removal rate of inorganic matters is increased, and the effluent quality is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental functional materials and sewage treatment, and in particular relates to a biological carrier for enhanced sewage treatment and its preparation method and application. Background technique [0002] At present, with the rapid development of industry and agriculture, the sewage generated in life has increased sharply, and the pollutants that need to be treated in water are increasing day by day, and there are various types. Due to the backwardness of my country's pipeline network construction, there is still a part of sewage that has not been intercepted and piped. If the sewage is received into the sewage plant in the later stage, it will inevitably increase the operating pressure of the sewage plant. With the deterioration of the environment and the increasing attention of human beings to the living environment, the discharge standards of sewage plants continue to increase. However, due to t...
