Embodiment Construction

[0006] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0007] As shown in the figure, the process flow of the present invention: using tap water, surface water or groundwater as the water source, the raw water first enters the KDF treatment medium 1 of 10-15g for treatment, and KDF is a high-purity copper / zinc alloy particle. The two metals in the alloy form countless small primary battery systems on the submicroscopic scale, and use microelectrochemical oxidation-reduction reactions to remove chlorine, metal ions and compounds in water, and can significantly inhibit the growth and reproduction of bacteria, fungi, and algae. Softens dirt. The effluent of the KDF filter material enters the magnetically expanded bamboo charcoal filter material 2 of 80-110g. The magnetically expanded bamboo charcoal is composed of bamboo charcoal with a macropore radius, a transition radius and a micropore radius magn...

Abstract

The invention relates to the technical field of drinking water treatment, and concretely relates to a technology for the deep purification of drinking water through the combination of KDF (a high-purity copper-zinc alloy), a magnetic expanded bamboo charcoal particle medium and an internal pressure type PVC hollow fiber ultrafilter membrane. The technology is characterized in that the technology comprises the following steps: allowing raw water to enter the KDF medium, removing residual chlorine and heavy metals from water through the micro-electrochemical oxidation-reduction reaction of the KDF medium, softening dirt, and inhibiting the breeding of algae and bacteria; and allowing filter material outlet water to enter magnetic expanded bamboo charcoal for effective decoloring, residual oxygen removal, deodorizing and the adsorption of organic pollutants and metal ions, softening the filtered water with a resin, and discharging the softened water to the internal pressure type PVC hollow fiber ultrafilter membrane for substantial bacterium and particle removal, wherein the magnetic expanded bamboo charcoal particle medium can be cleaned through utilizing a backwashing system. The technology has the advantages of good treatment effect, low cost, simple operation and maintenance, and substantial completive advantages in the deep purification of the drinking water.

Description

technical field [0001] The invention belongs to the technical field of drinking water treatment, and specifically relates to a process for deep purification of drinking water by combined use of a KDF treatment medium, a magnetically expanded bamboo charcoal particle medium and an internal pressure PVC hollow fiber ultrafiltration membrane. Background technique [0002] With the rapid development of my country's economy and society and the continuous improvement of people's living standards, people's requirements for drinking water quality are getting higher and higher. Solving the problem of deep purification of drinking water and ensuring drinking water safety have become the basic needs of improving the production and living conditions of Chinese residents. However, the rapid development of modern industry has led to the increasingly polluted water environment. Many trace organic pollutants, soluble chemicals and chlorinated disinfection by-products that are toxic to the hu...
