How long does it take to design a wastewater treatment plant process? Thank you.

The sewage treatment process is as follows:

1. The wastewater first flows to the flocculation sedimentation tank after passing through the grid and screen, in order to make the treatment effect good, the coagulant is added to the flocculation sedimentation tank, so that the suspended solids in the wastewater treatment effect is better, the coagulation dosing also plays a role in regulating the wastewater, and the wastewater after flocculation and precipitation flows into the pre-aeration conditioning tank.

2. Air is introduced into the aeration conditioning tank to play the role of pre-aeration adjustment. The homogeneously regulated wastewater is pumped into a primary floating packing biochemical tank.

3. The aeration head with high oxygenation efficiency is installed in the biochemical tank and loaded with floating filler, which has proved that this technology has a high removal efficiency for COD and BOD. The wastewater in the primary floating filler biochemical tank flows into the secondary floating filler biochemical tank, and the method is the same in the second pool.

4. The water of the secondary floating packing biochemical tank flows into the inclined plate sedimentation tank. The addition of polypropylene honeycomb inclined pipe to the pool can greatly improve the settlement efficiency, in addition, the hydraulic load is high, the residence time is short, and the floor area is small.

5. The sludge precipitated by the coagulation sedimentation tank and the inclined plate sedimentation tank is discharged into the sludge thickening tank, and then dewatered by the sludge dewatering machinery.

6. The water discharged from the inclined plate sedimentation tank flows into the clear water tank and is discharged after testing.

1.Dirt lift pump room.

The sewage treated into the sewage is roughly deleted into the sewage lifting pump room, and then the sewage pump lifts the front pool of the grit tank, and the energy to be consumed by the pump accounts for the total energy consumption of the sewage transportation, which is related to the sewage flow rate and the head to be lifted.

2.Grit remover tank.

The function of the grit tank is to remove the heavier particles, and the grit tank is generally located in front of the pumping station, in front of the inverted siphon, so as to reduce the impact of the machine particles on the pump. The wear of the pipeline can also be set in front of the primary sedimentation tank, in order to reduce the load of the sedimentation tank and improve the treatment conditions of the sludge sheltering structure, the common grit tank has advection grit tank, exposed grit tank. Dole grit remover and bell grit remover.

The main energy required in the grit tank is the sand separator and the sand suction machine, as well as the exposure system of the grit tank, the dynamic system of the Dole grit tank and the bell grit tank.

3.Primary sedimentation tank.

The primary sedimentation tank is the subject treatment structure of the graded sewage treatment, or the pretreatment structure of the graded sewage treatment is located in front of the physiotherapy structure, and the object of treatment is SS and part of the BOD5, which can improve the operating conditions of the biometric treatment structure and reduce its BOD5 load, and the primary sedimentation tank comprises advection sedimentation tank, radial sedimentation tank and vertical flow sedimentation tank.

The main energy consumption equipment of the primary sedimentation tank is the sludge discharge device, such as the chain belt scraper, the sludge scraping and skimmer and the suction pump, etc., but due to the influence of the sludge discharge cycle, the energy consumption of the primary sedimentation tank is low.

Consumption is low.

4.Objects deal with structures.

For example, the energy consumption of the sewage treatment unit process accounts for more than 60% of the direct energy consumption of the sewage treatment unit, and the electric energy consumed by the exposure system of the activated sludge method is basically connected. And the power is relatively high, otherwise it can not achieve a better exposure effect, and the treatment effect is not good, the exposure machine installed in the oxidation ditch treatment process is also a very energy-consuming equipment, and the energy consumption of the Hongqin treatment equipment and activated sludge method is low, but it should be less in the past, and it is the treatment process that needs to be pushed in the future.

5.Secondary sedimentation tank.

The energy consumption of the secondary sedimentation tank is mainly in the suction of sludge and the removal of floating debris from the sludge. Low energy consumption.

6.Sludge treatment.

Thickening tanks in sludge treatment processes. The energy consumption of the sludge treatment unit is considerable, and the power consumption of these equipment is very high.

Looking at sewage, if you talk about reeds, how to turn decay into a simple service? Blockade.

See how sewage turns decay into magic?
