Lanthanum chloride can be realized the effect of P elements in adsorbed water body.Bio-film colonization 7-1 in three branch bar groups, according to from top to bottom
Sequence set gradually (attachment) and have aerobic nitrification bacterium, facultative denitrifying bacterium, anaerobic denitrifying bacteria.That is in three branch bar groups
Bio-film colonization 7-1 in that branch bar group of highest point is attached with aerobic nitrification bacterium, is located in the middle that branch bar
Bio-film colonization 7-1 in group is attached with facultative denitrifying bacterium, the bio-film colonization 7-1 attachment in that branch bar group of bottom
There is anaerobic denitrifying bacteria.
It is attached to denitrification microorganism on bio-film colonization 7-1, stickum can be metabolized out, and then keep with bio-film colonization 7-1
It is reliably connected, is not easy to be washed away by water flow.Again because waste water processed can through hole diameter be equal to 0.22 μm of semi-permeable membrane, and it is aerobic
Nitrifier can not be by semi-permeable membrane, therefore the aerobic nitrification bacterium in biomembrane bag is while playing good denitrification effect, itself
Loss will not be generated with the flowing of waste water processed.As it can be seen that being not easy on microorganism all in the utility model with being located
It manages the flowing of waste water and is lost.
Since a large amount of bio-film colonization 7-1 freely drifts in water, great contact area is kept with waste water processed；Therefore
The utility model has more significant and quick denitrification effect compared to the substrate of attachment denitrification microorganism.In addition, due to life
Denitrification microorganism can be metabolized out stickum on object biofilm 7-1, therefore bio-film colonization 7-1 can be sticked during drifting and be located
The suspended matter in waste water is managed, and then reduces the suspension content in waste water processed.When sticking together more suspension on bio-film colonization 7-1
When object, suspended matter will be combined into biggish particulate matter and precipitate.
The working principle of the utility model is as follows:
On-off valve 4 is opened, pump startup of intaking, will be in the waste water processed injection reaction tank 5 in intake pool 1.In reaction tank 5
Aerobic nitrification bacterium by the mineralized nitrogen in waste water processed be nitrate nitrogen；Facultative denitrifying bacterium, anaerobic denitrifying in reaction tank 5
The nitrate nitrogen in waste water processed is converted nitrogen by bacterium.Bio-film colonization 7-1 carries out the suspended matter reduced in waste water processed
Physics is carried out to shut off.Lanthanum chloride on bio-film colonization 7-1 is to the P elements adsorbed in waste water processed.Waste water processed is reacted
The water outlet in pond 5 overflows in discharge bay 6.
