Technology Promotion: Application And Advantages Of Fiber Ball Filter Material

?

It is widely used in various water treatment industries with the density of 1.38g/cm and the origin of Gongyi.

As the amount of urban sewage increases year by year in China, China has to implement more stringent sewage tail water discharge standards. However, the external treatment process of wastewater treatment plant in China is still in the secondary biochemical treatment process, and in a period of time in the future, or the local government can not require the sewage treatment plant to add advanced treatment processes such as activated carbon, ozone oxidation, reverse osmosis, etc.

In view of the increasingly stringent emission standards, secondary biological treatment is powerless, which should be a common understanding of the industry. The operation data showed that the SS removal rate was close to 90% when the suspended particles concentration decreased from 10-20 mg / L to less than 2 mg / L when the effluent was filtered by fiber ball; The COD concentration decreased from 70-80 mg / L to 40 mg / L, and the COD removal rate was close to 50%.

Fiber ball filtration can not only significantly improve the quality of tail water, but also meet the development trend; Moreover, it can filter at high speed, the filtration speed can reach 20-40m / h, and the filtration cycle can reach 10-20h, that is, it can be used for sewage filtration stably without frequent backwashing.

The investment of fiber ball filtration equipment is relatively low, generally about 20-30 yuan / (M3 water / day). Only 1-2% of the investment in secondary biochemical treatment process is needed to realize advanced wastewater treatment. The investment of other advanced treatment units is usually tens or even hundreds of times as much as that of fiber ball filtration. The regeneration of fiber ball filtration equipment is simple, only gas and water backwashing is needed, and the backwashing water consumption is small and the cost is very low. Compared with activated carbon adsorption, the regeneration cost can hardly be compared.

Fiber ball filtration equipment occupies a small area, usually equivalent to 1 / 40-1 / 20 of the secondary sedimentation tank. Due to its small volume, it is convenient to add the secondary biological treatment process in the existing wastewater treatment plant, and the reconstruction project is very simple. In addition, the volume of fiber ball filtration equipment is small, so it is often manufactured into tank type filtration equipment, which is also very convenient for transportation, movement and installation.
