The heavy metal type of removal（Or multiple types）It can depend on the type of sorbent material in this layer.For example, different types of
Sorbent material can adsorb different types of heavy metal.For example, some type of sorbent material can adsorb one kind
（Such as it is single）The heavy metal of type, it is different types of that some type of sorbent material can adsorb two or more
Heavy metal.
It therefore, can be according to the heavy metal type to be removed from water（Or multiple types）To select to adsorb in each equivalent layer
The type of agent material.In other types of sorbent material, the adsorbent that can be used in layer 102-1,102-2 ... 102-6
The type of material especially may include such as alumina-based material, titanium base material, iron oxide material and/or carbon-based material.For example,
Aluminium oxide can remove As and Pb, and titanium oxide can remove As, Pb, Cd and Hg, and zirconium oxide can remove As and Pb, and iron oxide can
To remove As, Cd and Pb, modified activated carbon can remove Pb.In addition, as previously mentioned, can be used in layer 102-1 and 102-2
The sorbent material of same type can be used, in layer 102-5 in the sorbent material of same type in layer 102-3 and 102-4
With the sorbent material that same type can be used in 102-6.
As example, the first kind of the heavy metal of the absorption first kind can choose to sorbent material 110 and 112
Sorbent material can choose the adsorbent of the Second Type of the heavy metal of absorption Second Type to sorbent material 114 and 116
Material can choose the sorbent material of the third type of the heavy metal of absorption third type to sorbent material 118 and 120.
In such example, when water flows through layer 102-1 and 102-2, can be removed from water by sorbent material 110 and 112
The heavy metal of one type.It, can be by sorbent material 114 and 116 from water then when water flows through layer 102-3 and 102-4
Remove the heavy metal of Second Type, and when water flows through layer 102-5 and 102-6, can by sorbent material 118 and 120 from
The heavy metal of third type is removed in water.
As additional example, the first kind for adsorbing two kinds of heavy metal can choose to sorbent material 110 and 112
The sorbent material of type can choose the suction for adsorbing the Second Type of two kinds of heavy metal to sorbent material 114 and 116
Attached agent material can choose the adsorbent material for adsorbing the third type of two kinds of heavy metal to sorbent material 118 and 120
Material.In such example, when water flows through layer 102-1 and 102-2, it is corresponding that sorbent material 110 and 112 removes it from water
Two kinds of heavy metal.Then when water flows through layer 102-3 and 102-4, sorbent material 114 and 116 can be removed from water
Remove its corresponding two kinds of heavy metal, and when water flows through layer 102-5 and 102-6, sorbent material 118 and 120 can be with
Its corresponding two kinds of heavy metal is removed from water.By the sorbent material of the first kind（Such as it is adsorbed agent material 110
