Structure, in order to both slitless connections.
The structure of above-mentioned water distribution block 3 is simple, easily sets.The porosity of water distribution block 3 is arranged such, makes input purifying layer 1
The discharge of sewage on top is big, and the discharge of sewage of input purifying layer 1 bottom is small, in order to make the top of input purifying layer 1 and bottom
Sewage quantity is uniform, and then sewage is fully purified in purifying layer 1.
Wherein, the length at the upper bottom of the prismatoid structure of handstand is more than the length of its bottom.The triangle body structure of handstand
Drift angle is located at lower end.
For the ease of making water distribution block 3 smoothly fix, preferably in the water distribution block 3 of handstand prismatoid structure.For the ease of setting
Set up and make, preferably water distribution block 3 is in the rectangular prismatoid structure stood upside down, and its hypotenuse waist connects with the end of purifying layer 1, in order to
Most of sewage is allocated to the top of purifying layer 1, and fraction sewage is allocated to the bottom of purifying layer 1, and then fills sewage
Divide and purified in purifying layer 1.
The structure of filter block 5 have it is a variety of, it is excellent based on simple in construction, attractive in appearance, and on the premise of being engaged with water distribution block 3
Select the trapezoidal body structure of filter block 5.
Water distribution block 3 and filter block 5 can be by obtaining in silk screen (such as silk screen of trapezoidal body structure) built-in back-up sand grain
.Now, the grit size in water distribution block 3 is from top to bottom gradually reduced, in order to water distribution uniformity.Sand grains in filter block 5 can
The mixture of big footpath sand grains and path sand grains is thought, in order to the fixation impurity in sewage after filtration, purification.
Water distribution block 3 and filter block 5 can also be the porous ceramics block materials that can turn on sewage.Now, water distribution block 3 can
Think what multilayer was from top to bottom placed, and the porous ceramic layer that porosity sequentially reduces, in order to water distribution uniformity.
