In addition, the weir plate 191 is also spaced from the slag trap 192. The reinforcing rib 193 is connected between the two weir plates 191. The weir 191 is preferably a triangular weir.
A water outlet 195 is provided on the bottom plate 196, and its end is connected to an outlet pipe of the MBBR-integrated sewage treatment apparatus 100 via a hose so that the treated water can be discharged outside the container.

The size of the holes is smaller than the minimum external dimension of the suspended filler. To prevent clogging of the sludge while ensuring water throughput, the size of the holes needs to be moderate.
Furthermore, the total number of holes (n) needs to be determined by rounding the quotient of the total water passing area (a) divided by the individual hole area (a). The total water passing area (A) needs to be calculated according to the water passing flow (Q) and the water passing flow velocity (v), and a safety factor (k, generally 1.2-1.5) is multiplied to ensure that water passing is not influenced when the hole part is blocked. Wherein the flow rate (Q) of the water passing is the reflux water amount actually required, and the flow rate (v) of the water passing can be 0.7-1.2 m/s. Wherein, when calculating the number of the through holes 155 on the water passing device 150, the water passing flow rate (Q) is the sum of the water inlet amount and the backflow flow rate.
The calculation formula is as follows:
A＝k*(Q/v)
n＝A/a
in an alternative embodiment, the suspended filler introduced into the treatment tank is a cubic polyurethane filler having outer dimensions of 20mm × 20mm × 20mm, and the shape of the holes may be 10mm × 50mm kidney-shaped holes.
After determining the size of the holes and the total number of the holes, it is necessary to determine the pitch of the holes according to the requirements of the material and strength of the suspended filler blocking device 174, the suspended filler blocking device 154 and the suspended filler intercepting device 160, the conditions of the existing production equipment, and the like, and then calculate the number of the holes on the side and the area of the side, so as to determine the overall size of the suspended filler blocking device 174, the suspended filler blocking device 154 and the suspended filler intercepting device 160. The floating filler blocking device 174, the floating filler blocking device 154, and the floating filler intercepting device 160 may be made of stainless steel or polypropylene, which has high corrosion resistance. In a preferred embodiment, the suspended filler damming device 174, the suspended filler damming device 154, and the suspended filler damming device 160 are made of stainless steel.
