Efficient rotary fiber bundle filter tank as well as filtering method and backwashing method thereof

Abstract

The invention relates to an efficient rotary fiber bundle filter tank as well as a filtering method and a backwashing method thereof. The efficient rotary fiber bundle filter tank comprises a closed tank body connected with a water inlet pipe, a water outlet pipe, a backwashing wastewater pipe and a backwashing air pipe, wherein each of the water inlet pipe, the water outlet pipe, the backwashing wastewater pipe and the backwashing air pipe is provided with a control valve; a fixing device is mounted at the bottom of the closed tank body; a perforated water collection pipe is mounted on the fixing device and positioned in the center of the closed tank body; a coupling device is mounted at the upper part of the closed tank body, and the upper end of the coupling device is connected with a motor through a rotary shaft; the periphery of the perforated water collection pipe is wrapped with a fiber bundle which is high in tensile and torsional strength, smooth in surface, corrosion-resistant and aging-resistant, one end of the fiber bundle is fixed on the fixing device, and the other end of the fiber bundle is fixed on the coupling device; a pressure sensor is further arranged in the closed tank body. The efficient rotary fiber bundle filter tank effectively overcomes shortcomings of high possibility of blockage, short filtration cycle, low possibility of full backwashing and the like of a conventional fiber bundle filter tank, and has the advantages of high filtering speed, high load, small occupied area, good outlet water quality and the like.

Description

technical field [0001] The invention belongs to the field of water supply treatment and sewage treatment, and relates to a fiber bundle filter, in particular to a high-efficiency rotating fiber bundle filter for removing suspended matter and sand particles in water, a filtering method and a backwashing method thereof. Background technique [0002] At present, the removal of suspended solids in water plants is generally through coagulation and sedimentation, and the interception and removal of suspended solids are realized in the filter tank to further reduce the SS or turbidity of the effluent. However, the load of sand filter or activated carbon filter is low, the floor area is large, there are disadvantages such as incomplete backwashing of the filter material, short filtration cycle, etc. Mechanical filters and fixed fiber bundle filters also have problems such as easy clogging and difficult backwashing. , is restricted in use.
