According to a preferred embodiment of the present invention, the back plate is provided with a plurality of through holes 160 for increasing the circulation of the sewage in the frame 100 and improving the treatment effect.
Fig. 6 shows a perspective enlarged schematic view of the handle portion of the hand-held photocatalytic fiber sewage treatment device, wherein the pull cord 220 is not shown.
According to a preferred embodiment of the present invention, as shown in fig. 6, a plurality of hooks 210 are disposed on the sidewall of the holding rod 200 along the axial direction thereof, a pulling rope 220 is connected to the bottom plate (as shown in fig. 4 and 5), a pulling rope channel 230 is disposed inside the holding rod 200, the pulling rope channel 230 communicates the inside and the outside of the frame body, the other end of the pulling rope 220 penetrates out of the sidewall of the holding rod 200 and can be connected to the hooks 210, and the pulling rope 220 controls the movement of the bottom plate, thereby controlling the stretching or shrinking of the photocatalytic fiber, and the operation is simple, and the pulling rope 220 adjusted to a proper position can be connected to the corresponding hook 210, thereby realizing stable catalysis for a long time.
The invention also provides a using method of the handheld photocatalytic fiber sewage treatment device, which comprises the following steps:
pre-stretching the photocatalytic fiber 400 to enable the skin layer to form skin extension deformation along the length direction of the photocatalytic fiber, then relaxing the stretching of the photocatalytic fiber to enable the skin layer to form a wrinkle structure on the outer surface of the skin layer in the contraction process, namely enabling the skin layer to deform plastically, driving the outer surface of the skin layer to generate multiple layers of wrinkles after the core layer is recovered, and enabling the wrinkles to be partially overlapped;
adjusting the line spacing of two lines of fixing bars 300 to a proper distance;
detaching the two back plates, winding the photocatalytic fiber 400 from one row of fixing rods 300 to the other row of fixing rods 300 in a reciprocating and staggered manner, and fixing two ends of the photocatalytic fiber 400;
connecting and fixing the two back plates, holding the holding rod by hand to place the frame body and the photocatalytic fibers in the frame body in water, and starting the ultraviolet lamp;
the connection of the pulling rope 220 with different hooks 210 is adjusted at regular time or according to the sewage treatment condition, so that the line spacing of two rows of fixing rods 300 is changed to stretch and contract the photocatalytic fiber 400, and the corrugated structure of the outer surface of the skin layer is flattened or shrunk to a predetermined degree.
According to a preferred embodiment of the present invention, the suitable distance is such that the photocatalytic fiber 400 is in a non-stretched state after being bypassed.
In summary, the photocatalytic fiber disposed inside the frame body is used for treating sewage, a water source in a small range can be treated by hand, and meanwhile, the photocatalytic fiber can be stretched to expose more catalytic area, so that the phenomenon of catalytic reaction interruption caused by covering the surface of the photocatalytic fiber with dirt or reactant is avoided, and the catalytic reaction process can be controlled to a certain extent by controlling the exposed catalytic area.
