Problems solved by technology

[0002] Most of the current electrolytic water treatment devices are relatively large in size, because the existing flat electrodes are limited by the electrode materials, and there are phenomena such as low specific surface area, low current efficiency, high energy consumption, unstable processing capacity, and electrode passivation.
The potential window is not wide enough to prevent pollutants from being completely treated or the quality of treatment cannot be fully guaranteed, resulting in the main purification object being urban tap water
In order to make up for these defects and give sufficient electrolytic treatment to sewage, the only way to increase the size of the electrode plate is to increase the overall size of the treatment device.
These electrolyzed water treatment devices mostly use an integrated electrolyzer, which makes the cleaning and replacement of the electrolyzer very inconvenient
The power used by the device is also relatively single, all powered by direct current.

Embodiment 1

[0024] See figure 1 As shown, the novel sewage treatment device provided by the present invention includes a housing 1, and a set of brackets 2 are provided at the bottom of the housing 1, and the brackets 2 function to support the housing. The housing 1 has an opening on one side and is provided with a door 9, and on the other side is provided a control room 5 containing a control circuit and a battery room 4 containing a battery. The control circuit adopts the control circuit commonly used in existing water treatment devices. The storage battery is connected to the solar cell panel 3, and the solar cell panel 3 is installed above the casing 1. A water inlet 6, an acidic water outlet 7 and an alkaline water outlet 8 are respectively provided on the outside of one side of the housing 1. A sliding groove 10 is provided on the bottom plate of the housing 1. An electrolytic cell 11 is also provided inside the casing 1. In this figure, for ease of understanding, the electrolytic ...

Embodiment 2

[0027] This embodiment is an improved technical solution of embodiment 1, please refer to image 3 As shown, the arrangement of the electrodes and the diaphragm inside the electrolytic cell 11 in this embodiment is different from that in the first embodiment. In this embodiment, two sets of electrodes are provided in the electrolytic cell 11, which are the anode 121, the cathode 141, and the diaphragm 131. , The anode 122, the cathode 142 and the separator 132. The above two sets of electrodes are separated by a diaphragm 133, so the electrolytic cell 11 in this embodiment has two anode compartments and two cathode compartments. Compared with the electrolytic cell in Embodiment 1, the sewage treatment efficiency of this embodiment is doubled.

Moreover, a diamond coating electrode is used and has very strong pollution resistance, and an electrolytic bath is easy to wash. The invention is a sewage treatment unit suitable for outdoor use.

Description

Technical field [0001] The invention belongs to the field of sewage treatment, and specifically relates to a new type of sewage treatment device. Background technique [0002] Most of the current electrolysis water treatment devices are relatively bulky, because the existing flat electrodes are limited by electrode materials and have low specific surface area, low current efficiency, high energy consumption, unstable processing capacity, and electrode passivation. The low potential window causes the pollutants not to be completely treated or the quality of the treatment is not fully guaranteed, resulting in the main purification object of the city tap water. In order to make up for these shortcomings and to give the sewage sufficient electrolysis treatment, the only way to increase the size of the electrode plate, which causes the overall size of the treatment device to increase. These electrolytic water treatment devices are mostly integrated electrolyzers in the use of electro...
