Abstract
An electrochemical water-treating apparatus and method using B-doped diamond membrane electrode for the slightly polluted water are disclosed. It can provide edible water and the clean water for other purposes.
Description
The invention belongs to the green technology process field, be specifically related to a kind of little source of sewage treatment unit and method.
Microbial contamination and the situation that has a pathogenic agent are two sanitary conditions that receive much attention in the tap water.Studies show that it is cheap that electrochemistry has working cost, be easy to install, be difficult for producing characteristics such as poisonous residual oxide.The Direct Electrochemistry The Application of Technology also progressively relates to a plurality of fields, for example foodstuff production water, tap water; Fountain, man-made tourist site water, swimming-pool water; Easily grow the water body of microorganism, as FRAME ON THE ROOF OF HIGH-RISE BUILDING water tank water, conditioned water etc.
The object of the invention just provides a kind ofly can be removed in the water microbial contamination and have pathogenic agent, makes the electro-chemical water sterilization method of the high boron-doped diamond membrane electrode that water can directly drink.
Principal feature of the present invention is that high boron diamond film electrode has good electrical conductivity, and high boron diamond film electrode has very wide electromotive force window in water medium, and this not only makes water medium can carry out oxygenizement, reductive action and floating removing simultaneously and acts on; And electrode current can improve 2-3 the order of magnitude.This electrochemical window is enough to produce efficiently the various free radicals with oxidation sterilizing ability.
Another characteristics of the present invention are that this high boron-doped diamond membrane electrode has very high chemistry and electrochemical stability, do not have absorption (different with other electrodes, it does not have the redox processes of electrode surface), its electrochemical response of organism and biological chemistry thing to keep stable, corrosion-resistant etc. in long time.
Enforcement is to carry out in high boron-doped diamond membrane electrode water treatment device, and high boron-doped diamond membrane electrode is to utilize filament forensic chemistry gas deposition stove (to be of a size of that 35mm * 70cm * 0.6mm) deposit thickness is the high boron-doped diamond films of 10 μ m at silicon substrate.Two interpole gaps are from being 6mm.
Below in conjunction with accompanying drawing patent of the present invention is described further.
Accompanying drawing 1 is the schematic top plan view of patent of the present invention.Accompanying drawing 1 shows that [1], [3] are respectively water-in and water outlet, and [2] are boron-doped diamond film electrode.
Accompanying drawing 2 is schematic side view of patent of the present invention.Accompanying drawing 2 shows that [1] is boron-doped diamond film electrode.[2] be water inlet or water outlet.
Embodiment 1 is to be example with FRAME ON THE ROOF OF HIGH-RISE BUILDING water tank water.Water medium is respectively 3/S and 2/S by the flow velocity of high boron-doped diamond membrane electrode water treatment device, and the voltage of executing is direct current 20V, and electrode current is respectively 200mA.Verify by the diseases prevention and control station, former FRAME ON THE ROOF OF HIGH-RISE BUILDING water tank water bacteria sum cfu/ml is that number can not be counted, and is respectively 6 and 5 by water bacteria sum behind the high boron-doped diamond membrane electrode water treatment device.Meet national direct drinking water standard fully.
Embodiment 2 is to be example with Tianjin river.Water medium is 1.5/S by the flow velocity of high boron-doped diamond membrane electrode water treatment device, and the voltage of executing is direct current 30V, and electrode current is 300_mA.Verify by the diseases prevention and control station, former Tianjin river total plate count cfu/ml is that number can not be counted, and adds up to 1 by the water bacteria behind the high boron-doped diamond membrane electrode water treatment device.Meet national direct drinking water standard fully.
Embodiment 3 is to be example with Tianjin river.Water medium is 1.5/S by the flow velocity of highly doped diamond film electrode water treatment device, and institute's voltage of executing is for exchanging 30V, and electrode current is 300_mA.Verify by the diseases prevention and control station, former Tianjin river total plate count cfu/ml is that number can not be counted, and adds up to 1 by the water bacteria behind the high boron-doped diamond membrane electrode water treatment device.Meet national direct drinking water standard fully.
Electrochemistry is widely used in water sterilization, and especially high boron doped diamond film electrode is becoming a kind of material of alternative traditional electrode with its excellent electrochemical properties, is a field with bright prospects.Boron-doped diamond electrode is considered to a kind of novel substitute of drinking water disinfection, replaces the sterilization equipment that is now using, uviolizing just, halogenation and membrane filter.
The present invention meets the environmental consciousness of saving water resources, practicality height not only, and have industrial utilization.
