Embodiment 1

[0064] Embodiment one: if image 3 As shown, the flocculation device is a flocculant adding device. The flocculant adding device includes a pipeline mixer 14, a dosing box 12 and a metering pump 13. The pipeline mixer 14 is installed on the filter inlet pipe 1, and the metering pump 13 is installed on the On the dosing box 12 , the flocculant in the dosing box 12 is transported to the inline mixer 14 through the operation of the metering pump 13 and fully mixed with the water source to be filtered in the filtered water inlet pipe 1 . The amount of flocculant added is controlled by the metering pump 13 to avoid wasting the dosage and improve the flocculation effect. By adding the flocculant in advance to the water source to be filtered, the impurities in the water source can be flocculated and the filtration effect is improved.

Embodiment 2

[0065] Embodiment two: if Figure 4 As mentioned above, the flocculation device is an electrocoagulation device, and the electrocoagulation device includes a box body 22. The water outlet end of the box body 22 is connected to the filter water inlet pipe 1, and the filter water inlet pipe 1 is provided with a raw water pump 19. In order to ensure that the raw water pump 19 sucks strength, the casing 22 is a sealed structure. The box body 22 is provided with a central shaft 21, and the box body 22 is provided with a motor 20 that drives the central shaft 21 to rotate. The motor 20 is a micro motor, which is small in size and takes up little space, but can provide enough power to drive the central shaft 21. turn. The central shaft 21 is spirally wound with auger blades 24 along its axial direction, and the auger blades 23 can be helically fixed on the central shaft 21 by welding, or the auger blades 23 and the central shaft 21 are integrally formed. The box body 22 is provided...

Embodiment 3

[0066] Embodiment three: as Figure 5 As shown, the flocculation device is an electrocoagulation device, and the electrocoagulation device includes a cylinder 25, which is provided with a positive electrode net 26 concentric with the cylinder 25, and a negative electrode is arranged between the cylinder 25 and the positive electrode net 26. net 27, and the negative electrode net 27 and the positive electrode net 26 are concentrically arranged, the filter water inlet pipe 1 stretches into the center of the cylinder 25, the outside of the cylinder 25 is provided with a driving motor 28 that drives the positive electrode net 26 to rotate, and the bottom of the cylinder 25 is provided with Drainage pipe 29 is arranged, is convenient to fully drain surplus water. The positive electrode net 26 and the negative electrode net 27 both adopt a cylindrical structure, and the ends can adopt a closed structure, so that the water source must pass through the electric field formed by the pos...

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...
