Description
Technical Field
The utility model relates to a sewage treatment technical field especially relates to a compound municipal sewage filter equipment.
Background
The fiber rotary disc filter tank is one of the most advanced filters in the world at present, and has the characteristics of good treatment effect, high effluent quality, stable equipment operation and the like. 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 turntable is fixed around the central rotary drum and is communicated 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 at 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 intercepted impurities on the inner side of the filter cloth are continuously increased, the filtration pressure difference is increased along with the increase of the intercepted impurities, and the water amount penetrating through the filter cloth is reduced. 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. During backwashing, the rotary table rotates, backwashing water is sprayed on the filter cloth at different angles until the rotary table rotates for a circle, the filter cloth is completely cleaned, backwashing is stopped, and the static filtering process is started again until backwashing is carried out again.
