The fiber rotary disc filter consists of a central rotary drum, a rotary disc, a backwashing system, a matched control electrical system and the like. The rotary disc is fixed around the central rotary drum and is provided with a communication hole with the central rotary drum. Raw water (sewage) flows into the rotary drum from an opening at one end of the central rotary drum and enters each rotary table through the communicating holes, filter cloth is arranged on two sides of each rotary table and is woven by stainless steel wires or polyester wires, and the minimum filter pore diameter can reach 10 mu m. After the raw water is filtered by the filter cloth, the clean water flows out of the filter cloth and is discharged out of the system from the filtered water outlet. Along with the filtration, the impurity that holds back of filter cloth inboard is constantly increased, and the filtration pressure differential increases thereupon, and the water yield that permeates through the filter cloth reduces. When the impurities are accumulated to a certain degree, the liquid level of the central rotary drum reaches a set value, backwashing is needed, and the impurities accumulated on the inner side of the filter cloth are washed out in a backwashing mode. The backwashing water pump extracts clear water penetrating through the filter cloth, sprays the clear water to the outer side of the filter cloth, washes off the intercepted impurities on the inner side of the filter cloth, and discharges the sewage outside the device after the washing. And during backwashing, the rotary disc rotates, backwashing water is sprayed on the filter cloth with different angles until the rotary disc rotates for a circle, the filter cloth is completely cleaned, backwashing is stopped, and the filter cloth enters the static filtering process again until backwashing is carried out again.
