Abstract
The present invention relates to a water treating technology of electrolysis and filling type filtering purification, which comprises the following steps: 1, water to be treated flows into an electrolytic device by a pump; 2, the electrolytic device adopts direct current electrolysis; 3, after direct current electrolysis, H2, O2, CO2, Cl2, etc. are generated in water in the tank; 4, electrolyzed water enters a filling type filter, and manganese sand, quartz sand, active carbon, magnetite, quartz, etc. can be filled in the filling type filter. The technology has the advantages that the technology fully utilizes air bubbles generated by the electrolysis and the electrolytic oxidation of organic substances to separate gas such as H2, O2, CO2, Cl2, etc. in the water, and the gas enters the filter for oxidation filtration; particularly, the particle sizes of the air bubbles generated by electrolysis are small; the particle sizes of hydrogen bubbles are from 10 to 30 micrometers, and the particle sizes of the oxygen bubbles are from 20 to 60 micrometers; the particle sizes of the air bubbles are much smaller than the particle sizes of 100 to 150 micrometers of air bubbles generated by the compressed air technology. The air bubbles generated by electrolysis have stronger capability to capture impurities than air, and the water quality is good.
Description
Technical field
The present invention relates to a kind of technology for the treatment of water, belong to field of environment protection.
Background technology
At present in water technology, particularly main in order to remove the filter plant of iron in the water, manganese metal, be earlier with pressurized air or through ejector, water and air are charged into the material filling type strainer, and this technology purpose is to produce a large amount of steam bubbles after making compressed air of processed water and jet, enter the material filling type strainer and carry out aeration and oxidizing reaction, its shortcoming is that equipment is huge, the working cost height, and coverage is little.
Summary of the invention
Handle the topic of returning that exists in order to solve iron in the aforementioned removal water, manganese metal water, the treatment process that the present invention adopts electrolysis and material filling type strainer to combine, its technical process is:
1, pending water flows to electrolyzer through pump;
2, electrolyzer adopts the single flow electrolysis;
3, producing in the water behind dc electrolysis in groove has H
2, O
2, CO
2And CL
2Deng;
4, the water after the electrolysis directly enters the material filling type strainer;
5, can be filled with in manganese sand, quartz sand, gac, magnetite and the quartz any one or more in the material filling type strainer.
Advantage of the present invention is, makes full use of bubble and organic electrolytic oxidation that electrolysis produces, makes and separates out H in the water
2, O
2, CO
2And CL
2Deng gas, enter and carry out oxidation behind the strainer and filter; Particularly the steam bubble particle diameter of electrolysis generation is very little, and hydrogen gas gun has only the 10-30 micron, and oxygen bubbles has only the 20-60 micron, and is more much smaller than the steam bubble particle diameter 100-150 micron that aforementioned pressurized air technology forms; The steam bubble that electrolysis produces is caught impurity, and to catch the impurity ability than air strong, and water quality is good; The steam bubble that electrolysis produces more helps catalytic oxidation in the material filling type strainer, can adopt multiple filler coupling, and the water quality after the processing has decolouring, deodorizing, sterilization, reduction COD, BOD turbidity, and deironing, demanganization effect spy are good, and can absorb the plurality of heavy metal ion.
Description of drawings
Accompanying drawing is a process flow sheet of the present invention.
Embodiment
See also shown in the accompanying drawing, pending water enters electrolyzer 1 behind water pump, and electrolyzer 1 adopts the dc electrolysis technology, separates out H in the water after the electrolysis treatment
2, O
2, CO
2And CL
2Deng gas, and enter material filling type strainer 2 with water, in material filling type strainer 2, the filler catalytic oxidation in the steam bubble that electrolysis produces and the material filling type strainer, filler can adopt multiple filler to mate, for example gac, quartz etc.
