Abstract
The utility model discloses a kind of EM bacterium biofilm sewage-treatment plants, it include cesspool, it is located at bottom of pond in cesspool and is provided with multiple filter columns, filter column includes cylindrical tube body, equally distributed multiple filter openings are provided on the side wall of tube body, tube body is provided with biologic packing material, and biologic packing material is coated with EM mycoderm.Biologic packing material and EM mycoderm in the utility model are simultaneously handled sewage, and nitrate nitrogen removal rate reaches 90% or more, and COD reduces by 85% or more.
Description
Technical field
The utility model relates to sewage treatment field, specifically a kind of EM bacterium biofilm sewage-treatment plant.
Background technique
With the aggravation of water pollution, eutrophication generally occurs for China's surface water body.It is tighter this requires being carried out to sewage
The denitrogenation dephosphorizing of lattice is handled.Nitrogen in sanitary sewage secondary effluent, ground landscape water body mainly with ammonia, nitrate, nitrite,
The form of organic nitrogen exists, and phosphorus therein mainly exists with orthophosphates and organic phosphorus form.Ammonia in advanced water treatment at present
Nitrogen mainly passes through microorganism nitrification in biological aerated filter, is NO3-N and NO2-N nitrogen mineralized nitrogen, but nitre
The removal rate of hydrochlorate nitrogen is not high.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of EM bacterium biofilm sewage-treatment plant, biologic packing materials
Sewage is handled simultaneously with EM mycoderm, nitrate nitrogen removal rate reaches 90% or more, and COD reduces by 85% or more.
The technical solution of the utility model are as follows:
A kind of EM bacterium biofilm sewage-treatment plant, includes cesspool, and bottom of pond is located in the cesspool and is arranged
There are multiple filter columns, the filter column includes cylindrical tube body, equally distributed multiple filter openings are provided on the side wall of tube body,
The tube body is provided with biologic packing material, and the biologic packing material is coated with EM mycoderm.
The biologic packing material selects zeolite combined packing.
Multiple supporting sleeves arranged in arrays, the tube body of the filter column are fixed on bottom plate in the cesspool
Bottom end is enclosed construction, and the biologic packing material is piled up in tube body, and the bottom of each filter column tube body extend into corresponding support
Support positioning is realized in casing.
It is located at each filter opening on the tube body and is provided with strainer.
The height of the tube body is 1900-2000mm, and diameter 120-150mm, the diameter of the filter opening is 1.5-
2.5mm。
The advantages of the utility model:
It is provided with filter column in the cesspool of the utility model, biologic packing material is provided in filter column, biologic packing material is coated with
EM mycoderm, biologic packing material pass through the ammonia nitrogen and organic matter of enriching low-concentration, and substrate concentration needed for improving microbial metabolism improves
Nitrification and denitrification reaction rate, EM mycoderm decompose oxidation of organic compounds, can promote floating organic compounds decomposition, degradation of ammonia nitrogen, nitrous
The harmful substances such as hydrochlorate, hydrogen sulfide increase dissolved oxygen in water, inhibit pathogenic microorganism and harmful substance, are not necessarily to aerator, greatly
The efficiency of sewage treatment is improved greatly, and treated that sewage nitrate nitrogen removal rate reaches 90% or more, and COD reduces by 85%
More than.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
See Fig. 1, a kind of EM bacterium biofilm sewage-treatment plant includes cesspool 1 and is set to more in cesspool
A filter column is fixed with multiple supporting sleeves 2 arranged in arrays on the bottom plate in cesspool 1, and filter column includes cylindrical pipe
Body 3, equally distributed multiple filter openings with strainer are provided on the side wall of tube body 3, and the bottom end of tube body 3 is enclosed construction, packet
The zeolite combined packing 4 for being covered with EM mycoderm is piled up in tube body 3, and the bottom of each filter column tube body 3 extend into corresponding support sleeve
Support positioning is realized in pipe 2.
Wherein, the height of tube body 3 is 1900-2000mm, and diameter 120-150mm, the diameter of filter opening is 1.5-2.5mm.
Wherein, the zeolite combined packing 4 for being coated with EM mycoderm is to mix in proportion after being crushed by zeolite ore with cement, is mixed
It closes material and obtains zeolite combined packing through extruding pelletization, then zeolite combined packing is placed in 10-50 times of diluted EM bacterium stoste
After impregnating 2-4 days, EM bacterium bag is wrapped in zeolite combined packing surface and forms the zeolite combined packing 4 for being coated with EM mycoderm.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
