The inclined plates in the inclined plate sedimentation tank are a plurality of inclined plates which are inclined by 60 degrees and are arranged in parallel at a short distance to form a box body, water flows upwards from the bottom of the box body, suspended matters are precipitated and fallen to the upper surfaces of the inclined plates, and clean water flows out from the tops of the inclined plates. The surface of the sloping plate is flat, no dead angle exists in water flow, bacteria do not have places to attach and take roots, and therefore bacterial dirt is not easy to breed. However, the swash plate tends to be deformed by its own weight, that is, the bending strength of the thin plate is insufficient, and the thickness of the swash plate needs to be increased, which leads to an increase in production cost. This is a main reason why the swash plate cannot be popularized.

The film sloping plate 2 comprises sloping rods 3 and a film panel, wherein the two ends of the film panel are wound on the two sloping rods 3 after being tightened and are fixed by an adhesive.

The rigid inclined rods 3 at the two ends are connected with the middle film panel into a whole to form the film inclined plate 2. And when all the inclined rods 3 of the inclined plate precipitator are provided with the film panels, the manufacture of the film inclined plate precipitator is finished. The two ends of the diagonal rod 3 are respectively fixed on an upper main beam 7 of the upper layer plane frame 4 and a lower main beam 8 of the lower layer plane frame 5.

The number of the upper cross bars 9 in the upper layer plane frame 4 and the lower cross bars 10 in the lower layer plane frame 5 can be determined to be 2-3 according to the whole length of the precipitator. The sections of the upper main beam 7 and the lower main beam 8 are rectangular square tubes, the horizontal sides of the square tubes are long, and the upper sides and the lower sides of the square tubes are short.

Two 60-degree-angle parallelogram rhombus frames 6 on the side surface between the upper layer plane frame 4 and the lower layer plane frame 5 are formed by connecting inclined rods 3 inclining 60 degrees with an upper main beam and a lower main beam 8, and the inclined rods 3 are respectively fixed on square tubes of the upper layer plane frame 4, the upper main beam 7 of the lower layer plane frame 5 and the lower main beam 8 to form a parallelogram rhombus.

The section of the diagonal rod 3 is a round pipe or a square pipe, the diagonal rod 3 inclines at an angle of 60 degrees, the diagonal rods 3 are arranged in parallel, and the upper end and the lower end of the diagonal rod 3 are respectively fixed on the upper main beam 7 and the lower main beam 8 of the upper-layer plane frame 4 and the lower-layer plane frame 5. The distance between the inclined rods 3 is the distance between the film inclined plates 2. The spacing is typically 40mm to 100 mm.

Namely, the film is pulled, the transverse stay bars are pressed, the magnitude of the two forces is equal, the directions are opposite, and the mechanical balance is achieved.

And the film inclined plate box in the sedimentation tank is arranged on a steel beam reserved in the middle of the sedimentation tank and is firmly fixed. The water flow slowly flows upwards from the bottom through the film inclined plate sedimentation box, suspended matters in water are settled on the surface of the film inclined plate under the action of gravity and slide downwards to the bottom of the tank along the film, and residual clear water flows upwards out of the film inclined plate sedimentation device, so that the aim of solid-liquid separation is fulfilled.

During long-term use, the tension of the film roll 2 may become loose, and the film surface may be slightly bent downward at the center to become an arc-shaped film roll. The thin film sedimentation function is not influenced, and the sludge on the surface of the inclined plate tends to flow and gather to the bottom of the middle ditch, so that the downward sliding of the sludge can be accelerated.

The surface of the thin film sloping plate 2 is smooth and flat, and little mud is accumulated during operation. The frequency of flushing the inclined plate by bottom aeration can be reduced. Even if aeration washes the inclined plate, the used aeration amount is small. When the inclined plate is aerated, bubbles rise to cause the violent vibration of the film, which is much larger than the vibration amplitude of the rigid inclined plate, and the surface of the film is smooth, so that the sludge can quickly slide.

The thin film sloping plate 2 is a new generation water treatment device, has the advantages of low cost, high precipitation efficiency, difficult mud accumulation, convenient operation and maintenance and the like, and can be widely applied to the environmental protection industry of China.
