Equipment characteristics
1. The spacing of the inclined plates is greatly reduced, thereby greatly improving the utilization rate of precipitation space;
2. Due to the small Reynolds number, it can effectively restrain and suppress hydraulic pulsation, thereby greatly reducing the negative impact of the disturbance of the water flow details on the settlement of alum flowers;
3. The water distribution is uniform, and short-flow phenomenon will not occur;
4. Due to the structural optimization, the high-efficiency inclined plate precipitation equipment has no lateral constraints, which is more conducive to the settlement and separation of alum flowers;
5. The sludge area of the inclined plate filler is equal to the sludge discharge area, and the sludge discharge area is more than 4 times that of the ordinary inclined pipe, which greatly increases the sedimentation sludge load;
6. Due to the structural characteristics of the high-efficiency inclined plate precipitation equipment, and the thicker ethylene-propylene copolymer plates and supporting profiles adopted by it, it has an incomparable rigidity of ordinary inclined pipes and is not easy to deform under heavy loads.
The inclined tube sedimentation tank is based on the shallow layer theory:
If the amount of treated water is constant and the effective volume of the sedimentation tank is fixed, the sedimentation area, overflow rate, or load per unit area will be reduced, so there is more suspension It can be designed based on the principle of precipitation.
The inclined tube sedimentation tank is composed of equipment box, water distribution coagulation system, inclined tube area, water collection system, dosing system, sludge collection hopper and sludge treatment system.
The raw water enters the first-stage agitated coagulation reaction tank and then enters the second-stage flocculation tank. The wastewater that needs to be precipitated after the coagulation and flocculation through the dosing enters the equipment through the water inlet and is evenly distributed under the inclined pipe by the water distribution system. The water flows upward through the sloping pipe, collects through the water collection system, and then discharges the equipment. The sediment slides down the sloping pipe to the settling hopper. The sludge is pumped directly by the sludge pump to the plate and frame filter press for sludge squeezing. Recycling.
The length of the inclined tube sedimentation tank is L, the horizontal flow velocity in the pool is V, and the particle sedimentation speed is u0. Under ideal conditions, L / H = V / u0. It can be seen that when the L and V values are unchanged, the shallower the pool depth H, the smaller the suspended particles that can be removed. If a horizontal partition is used to divide H into 3 layers, each layer has a depth of H / 3. Under the condition that u0 and v are unchanged, only L / 3 can remove the particles of u0. That is, the total volume can be reduced to 1/3 of the original. If the tank length is constant, the horizontal flow rate can be increased to 3v due to the tank depth of H / 3, and the particles with a sedimentation rate of u0 can still be removed, that is, the processing capacity can be increased by 3 times. At the same time, dividing the sedimentation tank into n layers can increase the processing capacity by n times.
