Variable gap type fiber bundle filter and application method thereof

Abstract

The invention belongs to the technical field of water treatment equipment, and discloses a variable gap type fiber bundle filter and an application method thereof. The filter comprises a shell, a filtration water inlet pipe, and a filtration water outlet pipe, wherein the filtration water inlet pipe and the filtration water outlet pipe are arranged on the shell. A transmission rod and a fiber bundle filtering element are arranged in the shell. The filtration water outlet pipe stretches into the fiber bundle filtering element. The filtration water inlet pipe is provided with a flocculating device. A driving member is arranged on the exterior of the shell. The upper end and lower end of the transmission rod are respectively provided with an upper connection plate and a lower connection plate that are connected to the fiber bundle filtering element. The transmission rod drives the upper connection plate to adjust the compression gap of the fiber bundle filtering element. According to the application method, at first, the wastewater is flocculated by the flocculating device, and then water is filtered by the fiber bundle filtering element, which can be washed and repeatedly used. The operation is simple, an adjustable compression structure is adopted, thus the filtration density can be adjusted according to the needs; the filtration water outlet pipe stretches into the fiber bundle filtering element, the water side-stream degree is reduced, the filtering effect is improved; the fiber bundle filtering element can be repeatedly washed and used, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, in particular to a variable-gap fiber bundle filter and its application method. Background technique [0002] Filtration is the most commonly used process in water treatment and is an indispensable step in all water purification processes. Filtration can not only remove suspended solids in water, but also reduce chemical oxygen demand, biochemical oxygen demand, heavy metal ion concentration, oil content and chroma with the removal of suspended solids. With the rapid development of social economy, the demand for water supply is increasing day by day, making the purified water market enter a new period of development. Traditional water supply treatment processes generally use various filter pools, pressure filters, and integrated water purification equipment, all of which use quartz sand as the key filter material, but nano-scale pollutants with a particle size of less than 1 μm...
