Reverse suction device of a fiber rotary disc filter

Abstract

The invention discloses a reverse suction device of a fiber rotary disc filter and relates to a water treatment equipment component. The reverse suction device of the fiber rotary disc filter comprises an outlet (1), a main pipe (2), a branch pipe (3), a reverse suction disc surface (4), a loosening filter cloth groove body (5), a dirt suction groove body (6) and an adjusting valve (7), wherein a flange of the outlet (1) of the reverse suction device is connected with an valve at an inlet of a reverse suction water pump. According to the reverse suction device of the fiber rotary disc filter, firstly, fiber filter cloth is loosened, after a rotary disc filter rotates for a certain angle, sludge adhered to the fiber filter cloth is sucked out by the dirty suction groove body (6), according to the reverse suction device of the fiber rotary disc filter, the washing effect of the fiber filter cloth is greatly improved, the reverse suction is complete, the filter cloth is washed thoroughly, the filtering period is long, the filter cloth is not easy to block and the alga is not easy to breed, the water and energy consumption is low, and the service life of the filter cloth is remarkably prolonged.

Description

technical field [0001] The invention relates to a component of water treatment equipment, in particular to a reverse suction device for a fiber rotary disc filter. Background technique [0002] With the development of society and the improvement of people's living standards, the requirements for the environment are getting higher and higher, and the water discharged by sewage treatment plants (stations) is also increasing. Now most of the water discharged by newly built sewage treatment plants (stations) All require to meet or exceed the first-level A standard of the urban sewage treatment plant pollutant discharge standard (GB18918-2002), among which suspended solids in water is an important indicator. It is widely used due to the advantages of simple and convenient maintenance, low land occupation, small head loss, and good effluent quality. The most important components of the fiber rotary disc filter are the fiber filter cloth filter disc and the back-suction device, bu...
