Introduction to the operation process of sewage treatment equipment

The rapid growth of industry has led to increasingly serious environmental problems, therefore, almost all polluting enterprises must install environmental protection equipment. For example, if a company discharges sewage, it must install sewage treatment equipment. So, what is the treatment process of sewage treatment equipment? Today, the DTRO equipment processing manufacturer will explain to you.

1. After the wastewater passes through the grid and screen, the pollutants with large particles are removed, and then it passes through the sedimentation tank where chemicals are added to regulate the wastewater. Then the remaining wastewater flows into the pre aeration regulating tank.
2. Injecting air into the aeration regulation tank plays a role in pre aeration regulation. The uniformly regulated wastewater is pumped into the first stage floating packing biochemical tank.
3. The aeration head with high oxygen filling efficiency is installed in the biochemical tank, and floating packing is installed. Practice has proven that this technology has high removal efficiency for COD and BOD. The wastewater in the first stage floating packing biochemical tank flows into the second stage floating packing biochemical tank by itself, and the method used in the second stage is the same.
4. The water from the secondary floating packing biochemical tank flows into the inclined plate sedimentation tank by itself. Adding polypropylene honeycomb inclined pipes to the tank can greatly improve sedimentation efficiency. In addition, the hydraulic load is high, the residence time is short, and the occupied area is small.
5. Discharge the sludge into the sludge concentration tank, dry and dehydrate it, and then transport it out.
6. Test the clean water and if it meets the standards, discharge it directly.
