Water treatment technology of electrolysis and packed type filter purification

Abstract

The water treatment technological process of electrolysis and packing filter purification of the present invention is: 1. The water to be treated flows into the electrolysis equipment through the pump; 2. The electrolysis equipment adopts direct current electrolysis; 3. After direct current electrolysis, organic h 2 , O 2 , CO 2 and CL 2 etc.; 4. The water after electrolysis enters the packed filter; the packed filter can be filled with any one or more of manganese sand, quartz sand, activated carbon, magnetite and quartz; the advantage is that the electrolytic The generated air bubbles and the electrolytic oxidation of organic matter cause the precipitation of H in the water 2 , O 2 , CO 2 and CL 2 After the gas enters the filter, it is oxidized and filtered; especially the particle size of the bubbles generated by electrolysis is very small, the hydrogen cannon is only 10-30 microns, and the oxygen is only 20-60 microns, which is 100 microns larger than the bubbles formed by the aforementioned compressed air process. -150 microns are much smaller; the air bubbles generated by electrolysis have a stronger ability to capture impurities than air, and the water quality is good.

Description

technical field [0001] The invention relates to a process for treating water, which belongs to the field of environmental protection. Background technique [0002] At present, in the water treatment technology, especially the filter equipment mainly for removing iron and manganese metals in the water, the water and air are first filled into the packed filter with compressed air or through a jet device. The purpose of this process is to make the treated After compressed air and jet flow, a large number of bubbles are generated in the water, which enters the packed filter for aeration and oxidation reaction. The disadvantage is that the equipment is huge, the operating cost is high, and the scope of involvement is small. Contents of the invention [0003] In order to solve the aforementioned problems in the removal of iron and manganese in water, the present invention adopts a treatment process in which electrolysis and packed filters are combined, and its technological proc...
