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.
Referring to fig. 1, there is shown a block diagram of an embodiment of a sewage treatment apparatus according to the present invention.
In this embodiment, the sewage treatment apparatus includes a power supply apparatus and a reactor. Wherein the power supply device is used for supplying electric energy to the reactor.
The reactor comprises a water inlet pipe 3, a water outlet pipe 8, a shell 4 and an inner container 6 arranged in the shell.
Wherein, the shell 4 is provided with a water inlet for inserting the water inlet pipe 3 and a first water outlet for inserting the water outlet pipe 8, and the height of the water inlet on the shell 4 is higher than that of the water outlet on the shell 4.
An electrode plate 9 for purifying sewage entering the inner container 6 and a second water outlet for inserting the drain pipe 8 are arranged in the inner container 6.
When sewage is treated, sewage entering the shell through the water inlet pipe 3 enters the inner container 6 from the bottom of the inner container 6, is purified through the electrode plate 9 and then is discharged through the drain pipe 8 inserted into the inner container 6 through the first water outlet and the second water outlet.
Preferably, the sewage treatment device may further include a filtering device 5. The filtering device 5 is fixedly arranged on the bottom edge of the shell 4, and the bottom of the inner container 6 is tightly connected with the top of the filtering device 5. The sewage entering the shell 4 enters the inner container through the bottom of the inner container 6 after larger waste residues are filtered by the filtering device 5. Therefore, impurities (such as biological waste residues) with large volume in the sewage can be ensured to be remained in the shell 4 and not enter the inner container 6, and the sewage treatment capability of the electrode plate 9 is ensured.
In the process of sewage treatment, the water inlet pipe 3 discharges sewage into the shell 4, the sewage reaches the bottom of the shell 4 and is filtered by the filtering device 5, and water enters the inner container 6 under the action of pressure. With the increasing of the sewage, the water level in the inner container 6 rises continuously, and the electrode 9 is immersed into the water to purify the water continuously. When the water level reaches the level with the water outlet, the treated water can be discharged.
As a preferable aspect, the housing 4 may include a first top cover and a housing body. The liner 6 may include a second lid and a liner body. The first top cover is detachably connected with the shell body, and the second top cover is detachably connected with the liner body. Thus, the inside of the housing 4 and the inner container 6 can be conveniently cleaned, thereby prolonging the service life of the sewage treatment device.
The first top cover and the second top cover can be respectively provided with a first through hole and a second through hole for the lead 2 to pass through; the lead 2 is used for transmitting the electric energy output by the power supply device to the electrode plate 9, so that the electrode plate 9 can purify the sewage.
In one embodiment, the power supply device may include a solar photovoltaic panel 1. The solar photovoltaic panel 1 is used to convert solar energy into electric energy and supply the electric energy to the electrode plate 9 through the lead wires 2. Thus, the sewage treatment device in the embodiment can be powered by solar energy only, and other external energy is not needed.
In one embodiment, the electrode plate 9 may include a positive electrode plate and a negative electrode plate disposed in parallel. The positive electrode plate can decompose organic matters in the sewage entering the inner container 6, and the negative electrode plate can reduce metal ions in the sewage entering the inner container 6 into metal simple substances and make the metal simple substances adhere to the metal simple substances.
Preferably, the first top cover is further provided with an exhaust hole 11 for exhausting air in the housing 4. Thus, after the sewage enters the housing 4, the air in the housing can be exhausted to the outside through the exhaust hole 11, thereby increasing the speed of the sewage entering the housing 4.
Preferably, the second top cover is further provided with a froth discharging hole 10 for discharging froth generated by the treatment of the positive plate to a gap between the shell and the inner container. This can further prevent the foam from being discharged to the outside of the treatment apparatus through the drain pipe 8.
Preferably, the drain pipe 8 is L-shaped and includes a horizontal portion and a vertical portion. The vertical part is located in the inner container, and the horizontal part is led to the outside of the shell 4 through the first water outlet and the second water outlet.
The bottom end of the vertical part of the water discharge pipe is not higher than one half of the height of the inner container 6, so that the water purified by the electrode plate 9 can be discharged as soon as possible, and the purification efficiency is improved to a certain extent.
As a preferable mode, the sewage treatment apparatus of the present invention may further include an artificial wetland 12 and a water collection tank 13. The horizontal part of the drain pipe 8 is connected to the water inlet of the artificial wetland 12.
The artificial wetland 12 is used for removing organic matters in water entering through the water inlet of the artificial wetland and discharging the treated water to the water collecting tank 13 through the water outlet of the artificial wetland. The plants and the microorganisms in the artificial wetland can further purify the water entering the artificial wetland, remove organic matters in the water and reduce the contents of nitrogen and phosphorus in the water.
The water collection sump 13 may also include an outlet conduit 14. The purified water in the water collection tank 13 can be recovered and reused through the outlet conduit 14.
The sewage treatment device has the advantages of simple structure, long working time, low running cost, small occupied area, energy conservation and no secondary pollution, and can work simultaneously by a plurality of sewage treatment device groups, so that the treatment capacity is large; the effect of removing nutritive salts such as COD, nitrogen and phosphorus is good, and organic matters which are difficult to degrade, toxic and harmful in the sewage can be effectively removed; the pest and disease damage in the sewage can be reduced, and the sanitary condition of the rural area can be improved; it can beautify environment, and the treated water can be recycled.
In the apparatus and method of the present invention, it is apparent that the components or steps may be disassembled, combined, and/or reassembled after disassembly. These decompositions and/or recombinations are to be regarded as equivalents of the present invention. It is also to be noted that the steps of executing the above-described series of processes may naturally be executed chronologically in the order described, but need not necessarily be executed chronologically.
