Description

Solar energy combined type electrolysis sewage treatment flotation device
Technical Field
The invention relates to the technical field of sewage treatment in environmental engineering discipline, in particular to a solar combined electrolysis sewage treatment floating device.
Background
The electrolytic process for treating sewage is a process of purifying sewage by using the redox reaction of a cathode and an anode and taking the sewage as an electrolyte solution through electrochemical action, indirect oxidation or reduction action, particle polarization, electro-flotation action, electro-flocculation action and the like. When the anode is made of soluble Fe and Al, porous flocculent (or gelatinous) metal hydroxide is formed, and can perform a condensation effect on suspended matters, particles, organic or inorganic pollutants in the sewage through surface adsorption, charge action and the like, so that the water quality is purified.
The electrolysis sewage treatment method has the advantages that: the direct current power supply supplies power, so that a large amount of chemical agents are not required to be input, and secondary pollution to a water body is avoided; the voltage can be adjusted to deal with the change of the concentration of the pollutants in the water; the effluent quality is stable, the device is simple and easy to operate, and the occupied area is small.
The biomembrane process water treatment technology is a process of utilizing certain solid carriers to construct living space of microorganisms and carrying out treatment on organic sewage under the action of nutrients. The larger the specific surface area of the biological filler is, the easier more microorganisms are attached, and the better the water treatment effect is.
According to the prior art, the defects of the electrolytic method for treating the sewage are as follows: electricity consumption, a sufficient electricity supply is needed; when the anode material is a soluble material (i.e. the electrode material loses electrons and enters into the solution in the form of ions for chemical reaction), flocculent precipitate and impurities formed after a long time are easy to attach to the anode region, and the operation of an electrode bar (an electrode plate) is hindered.
If the water body is seriously polluted, the dissolved amount of oxygen is lower, which is very unfavorable for the microbial decomposition on the biological filler. And the traditional biological filler, such as a suspended biological filler, is easy to cause the phenomena of agglomeration, broken filaments, mutual winding and the like after being used for a long time.
In order to solve the problems, the solar combined type electrolysis sewage treatment floating device can effectively avoid the defects, achieve reasonable design and breakthrough the traditional water treatment scheme.
