Description
Technical Field
The invention relates to a sewage treatment device.
Background
With the continuous development of economic society, the total amount of sewage discharge is continuously increased, the treatment difficulty is continuously increased, and the treatment of sewage is greatly disturbed. The sewage treatment in sewage treatment plants generally adopts biological methods and chemical methods. If the biological rule is adopted, the reaction rate is slow, and the power consumption is very large; harmful gas in water cannot be removed well, so that the smell of the discharged water is relatively large; and substances which are extremely difficult to degrade or toxic and harmful substances can be generated in the reaction process of the biological reaction tank, and not only does the biological method need a large amount of aeration, but also the occupied area is large. If the chemical method is adopted, secondary pollution is generated, so that the subsequent treatment becomes complicated, and no cheap and effective chemical reagent is found at present, so that the sewage treatment cost is increased.
In the research of water treatment and organic matter removal, Chinese scholars also achieved some results. The patent document with the publication number of CN 102826632A and the name of 'in-situ adsorption-microelectrolysis-catalytic oxidation sewage treatment equipment and method' discloses a device for removing organic matters for practical application, wherein the device integrates adsorption, electrolysis and catalytic oxidation devices, the organic matters in water are adsorbed onto an adsorbent, and the adsorbent and two electrodes form a three-dimensional electrode to remove organic pollutants. But the disadvantages are also obvious, relying more on the electric field for power supply, and having a smaller treatment capacity and a higher requirement for the size and quantity of particles in the influent water. The patent document with the publication number of CN 2568632Y and the name of 'an algae removal device for an industrial cooling water system' discloses an effect of removing organic matters in a water body by destroying algae cells and oxidizing the organic matters in the water body by integrating the radiation, electrochemistry and optical principles. Its advantages are high efficiency and long service life. However, since the devices are integrated, the internal failure may cause difficulty in maintenance.
In summary, the research and the practical application of the electrochemical method for treating the organic matters in the water need to solve the problems of power supply and detachability.

Detailed Description
Embodiments of the present invention are described below with reference to the drawings. Elements and features depicted in one drawing or one embodiment of the invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that the figures and description omit representation and description of components and processes that are not relevant to the present invention and that are known to those of ordinary skill in the art for the sake of clarity.
As shown in FIGS. 1 to 3, the sewage treatment apparatus of the present invention comprises power supply units 7,8 and a reaction unit 1.
The power supply means 7,8 are used to supply electrical energy to the reaction apparatus 1. The reaction apparatus 1 includes a plurality of electrode plates 4 disposed in the wastewater tank. Wherein, the first edge of each electrode plate 4 is fixedly connected with the bottom of the sewage pool, each electrode plate is vertical to the liquid level of sewage to be treated, and the polarities of every two adjacent electrode plates are opposite.
In one embodiment, a second side of each electrode plate, which is opposite to the first side, is higher than the liquid level of the sewage to be treated. Each electrode plate with positive polarity is fixedly connected with a first side of the sewage pool, and each electrode plate with negative polarity is fixedly connected with a second side of the sewage pool, which is opposite to the first side.
In addition, the electrode plate having the positive polarity is not in contact with the second side of the wastewater tank, and the electrode plate having the negative polarity is not in contact with the first side of the wastewater tank.
In this way it is ensured that the sewage to be treated flows in the direction of the arrows shown in figures 2 and 3 after entering the sump from the inlet 3.
When sewage is treated, after water enters the sewage tank, the electrodes are alternately arranged in a staggered mode, so that the water flow distance is prolonged, the water retention time is prolonged, and more time is provided for the electrode plates to treat organic matters and reduce and adsorb heavy metal ions. Organic matters are decomposed at the positive plate and form foam to float on the water surface between the electrode plates, so that the organic matters can be conveniently cleaned; the heavy metal ions are reduced into simple substances on the negative plate and attached to the negative plate, so that the heavy metal ions are separated from the water body. Thus, organic matter and heavy metal ions in the sewage can be removed at the same time.
In one embodiment, the power supply means may comprise a solar photovoltaic panel 7 and a storage battery 8.
The solar photovoltaic panel 7 is used for converting solar energy into electric energy. The accumulator 8 is used to receive and store electric energy and to supply the electric energy to the reaction apparatus 1.
In one embodiment, the solar photovoltaic panel 7 may be placed on the roof of a fixed building, for example, to make the best use of space and reduce the footprint of the wastewater treatment plant.
In the daytime, the solar photovoltaic panel 7 starts to generate electric energy under the irradiation of sunlight, one part of the electric energy is used for enabling the reaction device to work, and the other part of the electric energy is transmitted to the storage battery 8 for storage, so that the reaction device can still operate under the condition of no illumination at night. Therefore, the external energy supply required by the sewage treatment device can be reduced, the working time of the sewage treatment device is prolonged, and the sewage treatment efficiency is improved.
As a preferred solution, the reaction device 1 of the sewage treatment plant may further comprise baffle groups 5, 6.
The baffle group is arranged on one side of the sewage pool close to the water outlet 2 and is used for preventing foam generated in the sewage treatment process from entering the water outlet.
In one embodiment, the baffle groups 5,6 may include a first baffle 5 and a second baffle 6.
Wherein, first plate 5 includes baffle body and logical groove, and the baffle body links firmly and perpendicular to the liquid level of pending sewage with the bottom of effluent water sump, leads to the groove mouth and upwards links firmly on the baffle body.
The second baffle 6 is fixedly connected with the first side and the second side of the sewage pool, and the bodies of the second baffle 6 and the first baffle 5 are positioned in the same vertical plane. The lower end of the second baffle 6 is inserted into the through groove and is not contacted with the groove bottom of the through groove.
Further, the upper end of the first baffle 5 is lower than the liquid level of the sewage to be treated, and the lower end of the second baffle 6 is lower than the liquid level of the sewage to be treated.
Through the first baffle plate 5 and the second baffle plate 6 with the structure and the connection relation, the treated water can be discharged from the water outlet of the sewage pool only after passing through the through groove of the first baffle plate 5 and the gap between the lower ends of the second baffle plate 6, so that the foam generated in the sewage treatment process can be prevented from being discharged through the water outlet and entering a subsequent treatment link.
The sewage treatment device of the invention also comprises a bus cable 9 which is used for transmitting the electric energy generated by the solar photovoltaic panel 7 to the storage battery 8 and the electrode plates in the treatment device 1.
The bus cable comprises a positive bus and a negative bus.
The positive bus is connected with the positive electrode of the solar photovoltaic panel 7, the positive electrode of the storage battery 8 and the electrode plate with positive polarity.
The negative bus is connected with the negative electrode of the solar photovoltaic panel 7, the negative electrode of the storage battery 8 and the electrode plate with negative polarity.
The sewage treatment device has small requirement on external energy, can work for a long time, has low operation cost, simple disassembly and easy maintenance, and greatly improves the working efficiency.
In addition, because the sewage water power retention time is long, the treatment is more thorough, and secondary pollution can not be generated. The electrode plate group can also play a great role in adsorbing heavy metal ions in sewage. And the arrangement of the solar photovoltaic panels does not occupy the land, thereby effectively saving the space. Provides possibility for further improvement and practicability of the technology for removing the organic matters in the water body by electrochemistry. The product can be suitable for the fields of domestic sewage, industrial sewage treatment and the like, and can also be used for the front-stage water treatment of water works.
