Oxidant, the MnO contained2It can play the role of catalysis to the oxidation of Fe in water (II) and Mn (II), by dissolved state
Ferrous iron or bivalent manganese be oxidized into the compound of undissolved ferric iron or tetravalent manganese, reach removing ferro in water and manganese
Purpose purifies water.
The embodiment of the present invention additionally provides a kind of underground water purified in situ processing method based on complex mineral filtrate, including
Following steps：
(1) Vertical Well hole 3 is drilled out to underground using drilling machine；
It (2), will in the filling to filter material frame 1 of complex mineral filtrate 11 mixed modified zeolite and natural manganese sand in proportion
Medicament injection pipe 4 is fixedly connected with the tubule of 1 bottom of filter material frame, and mounted filter material frame 1 is placed in 3 bottom of wellhole；
(3) drinking-water pipe 2 is put into wellhole 3, the filter material frame 1 is fixed in the floral tube part 21 of 2 lower part of drinking-water pipe
Center；
(4) clay, river sand are successively filled from the bottom up around the drinking-water pipe 2 successively, formation river sand protective layer 5,
Clay water barrier 6, and be compacted at well head；
(5) the medicament injection pipe 4 for exposing river sand protective layer 5 is connected with medicament injection pump 9, suction pump 7 respectively with drinking-water pipe 2
It connects, suction pump 7 in well from drawing water up to i.e. usable without silt in the water extracted out；
(6) when extracting well water water degradation out, medicament injection pump 9 extracts activator from dose-storage bucket 8 and is noted by medicament
Enter pipe 4 to inject in complex mineral filtrate, activate complex mineral filtrate, then extracted out activator by suction pump 7, is store to medicament
It deposits 8 injected clear water of bucket and cleans activated complex mineral filtrate 11, you can extract well water again and use.The activator is
The hydrochloric acid of 0.5mol/L and the sodium chloride mixed liquor of 0.5mol/L；Used modified zeolite and natural manganese sand filtrate are using one
After the section time, because absorption ammonia nitrogen reaches saturation inside modified zeolite, adsorption capacity declines；Natural manganese sand then because Surface Fe and
The deposition of manganese forms a large amount of ferrimanganic deposits, reduces ability of the manganese sand except iron, manganese, in this case it is necessary to be filtered to mineral
Material carries out activating and regenerating.
The mechanism of activating and regenerating is to be rinsed to mineral filtrate using faintly acid solution containing sodium ion, and demanganization sand is removed in dissolving
Impurity inside the ferrimanganic deposit and zeolite pores on surface, sodium at high concentration ion can also displace ammonia nitrogen so that zeolite is again
The secondary ability for restoring absorption ammonia nitrogen.Medicament uses water flushing again after injection cleaning a period of time, restores normal water outlet.
