Description
Technical Field
The invention relates to the technical field of photoelectrochemistry water purification, in particular to a drinking water treatment device for a construction site.
Background
The trend in drinking water treatment in recent years has been to use membrane separation to reduce contaminants in water. The advantage of the membrane is that a constant and well-regulated quality of water can be produced. The softener is more and more energy efficient with the increase of the waste liquid treatment amount and the reduction of the power consumption, but the problem of adding salt to the environment still exists. In addition to ion exchange, chemical precipitation is also often used to soften municipal primary water. This softening, commonly referred to as lime softening, involves adding lime to hard water to precipitate calcium ions such as calcium carbonate and magnesium ions such as magnesium hydroxide. However, disadvantages of lime softening include the production of a large lime mud stream and the chemicals required to be used, such as quicklime, coagulants (iron or aluminium based), soda ash and acids for adjusting the pH. Other methods of softening water include nanofiltration, electrodialysis, carbon nanotubes, capacitive deionization, reverse osmosis; although these processes consume large amounts of energy and the equipment is expensive to operate and maintain, primarily due to fouling. Therefore, especially in the case of remote construction sites where there is no direct potable water source, there is a need to develop an environmentally friendly, cost effective, low energy consumption process that would be an ideal complement to the water softening market.
Disclosure of Invention
The invention aims to solve the problems of sterilization and disinfection of softened drinking water and drinking water, and provides a drinking water treatment device for a construction site.
In order to achieve the purpose, the invention adopts the following technical scheme:
a drinking water treatment device for a construction site, comprising an anode chamber, a cathode chamber and an intermediate chamber, wherein the anode chamber, the cathode chamber and the intermediate chamber are separated by a heterogeneous ion exchange membrane; the heterogeneous ion exchange membrane comprises an anion exchange membrane disposed between the anode chamber and the intermediate chamber, and a cation exchange membrane disposed between the cathode chamber and the intermediate chamber; a titanium electrode anode is inserted into the anode chamber, a titanium electrode cathode is arranged in the cathode chamber, the titanium electrode anode and the titanium electrode cathode are connected with a power supply through leads, a tubular UV source is also inserted into the anode chamber, a sol-gel electrode coating is arranged on the surface of the anode, a water inlet is arranged below the middle chamber, and a water outlet is arranged below the anode chamber.
The volume ratio of the anode chamber to the middle chamber is 3-3.5: 1.
the titanium electrode anode and the titanium electrode cathode are both made by adopting titanium meshes with 8-18 meshes, the diameter of a metal wire of 0.01 and the open area of 67.24 percent, spot welding the titanium meshes into cylinders and then carrying out heat setting.
The reactor main body is made of engineering plastics.
The preparation method of the sol-gel electrode coating comprises the following steps:
magnetic stirring 5000mL of 0.1mol/L nitric acid, slowly adding 417mL of titanium isopropoxide, forming turbid suspension immediately after adding,
continuously stirring the suspension for 3-4 hr to gelatinize the suspension to form slightly turbid and bluish sol, dialyzing the sol after gelatinization to obtain high porosity coating,
the dialysis process increases the pH of the sol to a desired value of 8, thereby reducing electrostatic repulsion between colloidal particles in the sol, allowing the particles to slightly agglomerate,
the spectral/Por dialysis tubing had a flat width of 54 mm and a molecular weight cut-off of 3500kD, and prior to use, the tubing was washed in an aqueous solution of 0.001M EDTA and 2% by weight sodium bicarbonate,
after the sol was formed, it was applied to a titanium electrode by dip coating, and after coating, the electrode was heated in a furnace at 350 ℃ for 3 hours to form a xerogel coating.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
Referring to fig. 1, a drinking water treatment apparatus for a construction site includes an anode chamber, a cathode chamber, and an intermediate chamber, which are separated by a heterogeneous ion exchange membrane; the heterogeneous ion exchange membrane comprises an anion exchange membrane 12 disposed between the anode chamber 3 and the intermediate chamber 2, and a cation exchange membrane 13 between the cathode chamber 1 and the intermediate chamber 3; a titanium electrode anode 4 is inserted into the anode chamber, a titanium electrode cathode 5 is arranged in the cathode chamber, the titanium electrode anode 4 and the titanium electrode cathode 5 are connected with a power supply 10 through a lead 11, a tubular UV source 7 (ultraviolet light) is also inserted into the anode chamber 3, a sol-gel electrode coating 6 is arranged on the surface of the anode 4, a water inlet 9 is arranged below the middle chamber, a water outlet 8 is arranged below the anode chamber, the volumes of the anode chamber 3 and the middle chamber 2 are 675 milliliters and 200 milliliters respectively, the titanium electrode anode 4 and the titanium electrode cathode 5 are made by adopting a titanium mesh with 8x 18 meshes, the diameter of a metal wire is 0.01, and the open area is 67.24 percent and is formed by heat setting after being spot welded into a cylinder.
In the present invention, during the water softening process, calcium and magnesium ions enter the cathode chamber through the cation exchange membrane, chloride ions and other anions enter the anode chamber through the anion exchange membrane, where any pathogenic bacteria are inactivated by ultraviolet light, and photochemical oxidation of any organic matter in water is performed by TiO2And (5) finishing the electrode. Photochemical reactions are intended to oxidize any refractory organics (such as personal care products and/or pharmaceuticals) and to partially supply electrons to remove hardness. To accelerate this process, especially when the organic concentration in the water is low, an external potential can be applied and the electrolysis of the water can produce small amounts of hydrogen and oxygen.
When the uv lamp was turned on, the hardness removal increased to 14% and current was generated. When the UV lamp was turned off, no hardness was removed, and no current was generated. These results indicate that uv light is an important component of softened water in PEWT systems.
The PEWT system was able to remove 3.9 logs of bacteria using E.coli at a feed concentration of 7.8X104log and a hydraulic retention time of 1 hour. This removal rate can be increased by optimizing the reactor configuration for sterilization.
The experimental result shows that the adoption of the photoelectrochemistry water treatment device can ensure that the hard water softening and microorganism removal can reach 60 percent of hard water removal rate within 6 hours, and the pure water can obtain 3.9log of bacteria removal rate within 1 hour.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
