332 lead to filled media layer 21, for that will contain NO3-Water outlet be vented back to filled media layer 21.
And the utility model embodiment additionally provides a kind of method using artificial wetland treatment eutrophic water, it is described
Method uses the artificial swamp such as above-mentioned processing eutrophic water body to realize, comprising the following steps:
It S01., will be described by the water distribution pipe network by eutrophic water by being transported to water distribution pipe network from the first water inlet line
Eutrophic water is assigned to kind of the filled media layer for being implanted with plant, through the first water outlet after the filled media layer purified treatment
Outflow, obtains a purified water;
S02. first purified water is contained into zeolite fill area via the injection of the second water inlet line, carries out absorption and denitrogenates,
After denitrogenating qualification, the direct outlet of secondary purification water that will obtain;When denitrogenating unqualified, zeolite fill area is inhaled by nitrobacteria
Attached mineralized nitrogen is at NO3 -Afterwards, water outlet is fed back to the artificial swamp pond through the reflux line.
Method provided by the embodiment of the utility model using artificial wetland treatment eutrophic water, will be net from artificial swamp pond
Change a treated purified water, the strong adsorption treatment for passing through the zeolite fill area reduces nitrogen content;And since the zeolite is filled out
The nitrogen for filling area's absorption can be by nitrobacteria desorption, therefore, and the zeolite of the zeolite fill area can keep absorption property,
And the ammonia nitrogen through nitrobacteria desorption is due to being converted to NO3-, the effect through the denitrifying bacterium in artificial swamp pond is converted into N2,
The burden of NH_3-N treating is not will increase.
Specifically, the setting of the artificial swamp of the processing eutrophic water body is as described above, in order to save length, herein
It repeats no more.
In above-mentioned steps S02, when zeolite does not have adsorption saturation, NH_3-N treating effect is fine, can be improved treatment effect
30%, the obtained direct outlet of secondary purification water;When zeolite reaches adsorption saturation, ammonia nitrogen absorption can not be being realized, at this point, closing
The valve for closing control water outlet (outlet), after nitrobacteria completes desorption, connection water body flows back into filled media layer together,
It will be by the NO of mineralized nitrogen3-It is changed into nitrogen through denitrification.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
