Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The invention provides a eutrophic water body self-purification device, which comprises a ship body 1, wherein a photovoltaic power generation device, a constant-speed cruise system and an electrolysis device are arranged on the ship body 1, as shown in figure 1. The photovoltaic power generation device comprises a solar photovoltaic panel 2, a photovoltaic controller 3 and a photovoltaic storage battery 4, the electrolysis device comprises an anode 5 and a cathode 6 which are arranged below the ship body and are in contact with a water body, the anode 5 and the cathode 6 are magnesium rods, the specification of the magnesium rods is phi 15 x 135, the purity is 99%, and the depth of the magnesium rods inserted into the liquid level is 5.3 cm. The solar photovoltaic panel 2 is connected with a photovoltaic storage battery 4 through a photovoltaic controller 3, and the photovoltaic storage battery 4 is respectively connected with a constant-speed cruise driving motor 7 of a constant-speed cruise system and an anode 5 and a cathode 6 of an electrolysis device through leads.
The solar photovoltaic panel 2 is of a hemispherical dome-shaped structure formed by splicing a plurality of blocky monocrystalline silicon photovoltaic panels, and is beneficial to comprehensively receiving light irradiation at different times in one day. And a supporting column is arranged in the hemispherical dome-shaped structure. In this embodiment, the solar photovoltaic panel 2 is formed by splicing 21 pieces of 100ma monocrystalline silicon photovoltaic panels with phi 55 × 55cm, and has a hemispherical dome-shaped structure with a diameter of 20 cm. The photovoltaic storage battery 4 outputs a voltage of 1.5-2V to the anode 5 and the cathode 6 of the electrolysis device through the inverter 8.
A eutrophic water body self-purification method adopts the eutrophic water body self-purification device, a ship body 1 is driven by a constant speed cruise drive motor 7 of a constant speed cruise system to cruise in the eutrophic water body, sunlight is received by a solar photovoltaic plate 2 on the ship body 1 and is converted into electric energy through a photovoltaic controller 3 to be stored in a photovoltaic storage battery 4, the photovoltaic storage battery 4 provides 1.5-2V voltage for an anode 5 and a cathode 6 of an electrolysis device, a magnesium rod of the anode 5 can generate magnesium ions, ammonium magnesium phosphate crystals can be generated by combining with ammonia nitrogen and phosphoric acid in the water body and are deposited at the bottom of the water body, and therefore the water body purification is achieved.
The reactions that occur at the anode are:
Mg–2e-＝Mg2+ (1)
the reactions that occur at the cathode are:
2H2O+2e-＝H2↑+2OH- (2)
precipitation reaction equation (n ═ 0, 1 or 2) of magnesium ammonium phosphate (struvite) in the electrolytic cell:
HnPO4 3-n+Mg2++NH4 ++6H2O→MgNH4PO4·6H2O+nH+ (3)
the embodiment of the invention researches the electrolytic voltage output by the photovoltaic storage battery, tests the influence of different electrolytic voltages on the electrolytic process within the electrolytic voltage range of 0-12V, and the figure 2 shows the influence of different electrolytic voltages on the pH value of the water body. After the electrolytic voltage exceeds 2V, the pH value of the water body changes obviously, and the aquatic ecology can be influenced.
FIG. 3 shows the effect of different electrolysis voltages on the ammonia nitrogen escape rate, and FIG. 4 shows the effect of different electrolysis voltages on NH4+-effect of N removal rate. As can be seen from the figures 3 and 4, the escape rate of ammonia nitrogen (the part which can not be converted into struvite and escapes into the atmosphere to cause pollution) is the minimum under the voltage of 2V along with the increase of the electrolysis time, and the output voltage of the photovoltaic storage battery, which is set to be 2V, can meet the cruising of the driving motor at a constant speed and can effectively ensure the electrolysis effect.
According to faraday's law: the mass of the substance precipitated or dissolved at the electrode is proportional to the charge passed, and higher voltages can generate more magnesium ions while consuming more protons, resulting in a greater increase in solution pH. NH in solution4+Will gradually increase to NH with increasing pH3And (4) conversion, which leads to the increase of the escape rate of ammonia nitrogen. According to joule's law: with the same resistance, the amount of heat generated is proportional to the square of the voltage. The process of promoting ammonia volatilization at high temperature combines energy consumption and environmental protection factors, the 2V voltage has low energy consumption and objective recovery efficiency, and simultaneously, the generated ammonia gas is less, the influence on the environment is small, and the device is more suitable for being used as the selected voltage for electrolyzing and recovering struvite. Therefore, the voltage of no more than 2V, preferably 1.5V-2V, is adopted in the actual cruising electrolysis process.
In the embodiment of the invention, the magnesium ammonium phosphate precipitate generated by electrolysis is analyzed, an X-ray photoelectron spectrometer (Thermo Fischer, ESCALB 250Xi, USA) is used for adopting Al ka rays of 1486.6eV, and all binding energy of an XPS spectrum is used for carrying out charge correction by using C1 s-284.80 eV binding energy as an energy standard. Fitting atomic data for Mg, N and P using XPS peak software, XRD of the highly pure magnesium ammonium phosphate crystals as shown in figure 5 was obtained in good agreement with the XRD pattern of the standard magnesium ammonium phosphate samples, compared to the standard electron binding energy.
FIGS. 6 to 9 show XPS elemental analysis of struvite crystals prepared according to the present invention, and photoelectron spectroscopy analysis of respective Mg, N and P elements. As can be seen from the above figures, the magnesium ammonium phosphate crystals produced by electrolysis in accordance with the present invention are highly consistent with the magnesium ammonium phosphate crystals in the standard sample. The experimental product magnesium ammonium phosphate was demonstrated to be of high purity.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
