A device for removing iron and manganese from groundwater in a high-voltage electrostatic field

Abstract

The invention relates to a device for removing iron and manganese from underground water in a high-voltage electrostatic field, comprising an insulating outer cover, a high-voltage direct current power supply arranged in the insulating outer cover, a high-voltage electrostatic field ion separation chamber electrically connected to the high-voltage direct current power supply, and a high-voltage electrostatic field ion separation chamber connected A common oxidation reaction generator, the device also includes an electrolytic reaction generator connected to the high-voltage electrostatic field ion separation chamber, the top of the electrolytic reaction generator is provided with a port for passing into a liquid oxidant, and the electrolytic reaction generator An electrolytic cell, a filter plate and a water outlet are arranged in sequence from top to bottom, the electrolytic cell is electrically connected to a high-voltage DC power supply through a circuit, and the filter plate is arranged obliquely below the electrolytic cell. Compared with the prior art, the present invention has a simple and compact structure, is convenient to operate, is a micro-energy technology with low electrode consumption, and can quickly and efficiently remove excess Fe in groundwater 2+ and Mn 2+ , the purification treatment effect is good, safe and reliable, and can be popularized and applied on a large scale.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to a device for removing iron and manganese from underground water in a high-voltage electrostatic field. Background technique [0002] my country is rich in groundwater resources, many of which contain excess iron and manganese, known as iron- and manganese-containing groundwater. With the improvement of people's living standards, drinking water safety is getting more and more attention. When the concentration of iron ions and manganese ions contained in the water quality exceeds the standard, if it is directly used as drinking water, it will have a great impact on the human body. The state stipulates that the content of iron ions in drinking water should be ≤0.3mg / L, and the content of manganese ions should be ≤0.1mg / L. As we all know, both iron and manganese are elements needed by the human body. As long as the content in the water does not exceed the standard, it will not...
