SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide an aeration biological filter tank filled with composite filter materials in a glass fiber reinforced plastic cylinder, which has good treatment effect and long service life.
In order to achieve the above object, the utility model provides a following technical scheme: an aeration biological filter tank filled with composite filter materials in a glass fiber reinforced plastic cylinder comprises a tank body and is characterized in that the tank body is a vertical glass fiber reinforced plastic tank body, the top and the bottom of the tank body are both oval seal heads, a plurality of vent holes are formed in the seal head at the top of the tank body, and a water inlet is formed in the seal head at the bottom of the tank body; the lower part of the tank body is provided with a cobblestone cushion layer, the middle part of the tank body is provided with a composite filter material layer, and the upper part of the tank body is provided with a water outlet and a backwashing overflow port; an air inlet pipe penetrates through the end socket at the bottom of the tank body and extends into the lower part of the cobblestone cushion layer, and a plurality of single-hole membrane aerators are arranged on the air inlet pipe positioned in the cobblestone cushion layer. When the device works, the backwashing overflow port is closed, the water inlet enters sewage, the air inlet pipe enters air, and the air passes through the cobblestone cushion layer and the composite filter material layer and is discharged from the water outlet; during backwashing, the water outlet is closed, the water inlet is connected with backwashing water, and the air inlet pipe enlarges air inlet, so that intercepted impurities are flushed out from the backwashing overflow port.
Furthermore, the filter material of the composite filter material layer comprises ceramsite, zeolite, volcanic rock, glass filter material and active carbon.
Furthermore, a rain-proof cap is arranged above the vent hole.
Further, the height of the composite filter material layer is 2-3.5 m.
Furthermore, the particle size of the cobblestone material of the cobblestone cushion is 10-50 mm.
Further, the height of the cobblestone cushion is 0.4-0.8 m.
Furthermore, a one-way valve is arranged on the air inlet pipe to prevent backflow.
Further, the upper part of the tank body is provided with a feeding manhole.
Furthermore, the lower middle part of the tank body is provided with an inspection manhole.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model adopts the glass fiber reinforced plastic tank body, which is corrosion resistant and has long service life; the cobblestone cushion layer is used as a water distribution system, a structure that a porous plate is provided with a filter cap is omitted, and the problem that the connection strength between the porous plate and the wall of the tank body is insufficient in the manufacturing process of glass fiber reinforced plastic equipment is solved.
