[0026] Embodiment three:

[0027] The utility model Figure 1-Figure 3 As shown, it is disclosed that the fiber ball 3 is a modified fiber ball made of acrylic and polyester yarn, and the upper water distributor 1 and the lower water distributor 5 are plastic octagonal water distributors.

[0028] By adopting the above technical solution, the specification of the modified fiber ball is about 30mm. The modified fiber ball is more hydrophilic and oleophobic, has good elasticity, does not float on the water surface, and is easy to clean.

[0029] The working principle of the utility model is as follows: working process: raw water enters the upper water distributor 1 from valve HV-01 and enters the interior of the filter, the raw water passes through the fiber balls 3 from top to bottom, the density of the fiber balls 3 is greater than that of water, and the raw water naturally sinks to the bottom, and under the action of pressure during filtration, the fiber balls 3 cross each other to form a filter layer distribution state in which the upper part is loose and the lower part is dense, and the suspended matter, organic colloid, and grease pollutants in the water are intercepted, and the raw water after the suspended matter is removed passes through the quartz sand 4, enters the lower water distributor 5, and comes out from the valve HV-04, and the filtration flow rate is controlled at 35-45m / h.

[0030] Cleaning process:

[0031] A. Air washing: compressed air enters the lower water distributor 5 through valve HV-05, and is further evenly distributed through quartz sand 4 before entering the fiber ball filter layer. Compressed air forms bubbles of different sizes in the water, which swell or burst, and reach the upper water distributor 1, and pass through valve HV-02 to be discharged from the filter. Under the action of compressed air, the fiber balls 3 tumble in the water and become loose. At the same time, the fiber balls 3 rub against each other, so that the pollutants adsorbed on the surface of the fiber balls 3 are peeled off the fiber balls 3. The air washing time is controlled to be more than 5 minutes.

[0032] B. Backwashing. Close the compressed air inlet valve HV-05. The backwash water enters the lower water distributor 5 from HV-03, and is further distributed through the quartz sand 4. The backwash water enters the loose fiber balls 3. Under the action of water and air, the pollutants are further separated from the fiber balls 3. The pollutants enter the upper water distributor 1 along with the backwash water and are discharged from the filter by the valve HV-02. The backwashing time is controlled to be more than 15 minutes.

[0033] C. Emptying: After backwashing is completed, empty the backwash water remaining in the tank and let it stand for 5 minutes. The fiber ball filter is cleaned and ready for next use.
