Rotary immersed water treatment ultra-micro-filtering method and device

Abstract

The invention relates to a rotary immersed water treatment ultra-micro-filtering method and a rotary immersed water treatment ultra-micro-filtering device. The two ends of each hollow fibrous membrane wire are cast to an upper membrane wire disk and a lower membrane wire disk respectively; the upper membrane wire disk is connected with a water collecting tank; the lower membrane wire disk and a component base plate are fixed; a cavity of each membrane wire is communicated with a cavity of the water collecting tank; the membrane wires and the water collecting tank are integrated to form a membrane component; the water collecting tank is connected with a hollow shaft; the hollow shaft lifts the membrane component to a bearing seat and is communicated with a negative pressure water outlet pipe; a pin gear fixedly arranged on the water collecting tank, a speed reducer, a transmission shaft and a pinion form a driving device and the driving deice can drive the membrane component to rotate forwardly and reversely, so as to enable the membrane wires to be in a movement state; the negative pressure of a system is achieved in a pumping or siphon manner, raw water is filtered by a membrane, and pure water is drained from a negative-pressure water drainage pipe; due to the movement of the membrane component, the membrane wires and water flow move relatively, dirt attached to the surface of the membrane is taken away in time by the scouring force of the water flow, blocking of the surface of the membrane is effectively prevented, and the filter flow does not attenuate.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and relates to a rotary submersion ultra-microfiltration method and device for water treatment. Background technique [0002] Water is the source of life, one of the indispensable elements in economic development, industrial and agricultural production, and the material basis of human existence. Over the past few decades, with the reform and opening up of our country and the rapid development of industrialization, various industrial wastewater and domestic sewage with complex components often directly enter the water body without reaching the standard, resulting in a sharp decline in the quality of drinking water sources. Traditional drinking water purification technology is facing many problems. challenge. In addition, my country is a country seriously short of water, the per capita share of water resources is only 1 / 4 of the world's average level, and the water consumption per 10,000 y...

Problems solved by technology

[0005] The membrane and water body of the existing submerged continuous membrane filtration system are in a relatively static state. In the membrane filament fixing groove, negative pressure is generated in the membrane, so that the water passing through the membrane tube is discharged from the membrane filament fixing groove at both ends after being filtered by the membrane. Pollutants in this filtration method accumulate on the surface of the membrane, which makes the pores of the membrane filaments easily blocked and reduces the filtration efficiency.
