Lakes green water and industrial wastewaters new disposal method

Abstract

The formation of stagnant zones in fresh lakes leads to the formation of green water in these areas due to the formation and enhanced reproduction of phytoplankton under the sun influence. Over time, due to non-influx of fresh water, phytoplankton dies, releasing hydrogen sulfide, and green water becomes unusable and threatens the ecological situation of the lake. No less threat to the environmental situation are effluents into lakes of industrial wastewaters. Among the methods for treating these wastewaters, the electroflotation method is real. In the all existing electroflotation methods the salinity is formed in the space near cathode during the process of electrolysis that leads to formation of the salts sediments on the cathode that strongly cover cathode’s surface and may result of the total curtailment of the process of electroflotation. Besides, the anode uses the dense grid from the wire of the defined thickness that sharply reduces the transmittance of electrolysis bubbles through it and, therefore, a quantity of bubbles involved in the process of flotation that leads to a sharp worsening of the process itself. During the time, salt can close the grid and lock the output of the bubbles through the grid at all. In most cases, in the process of flotation, the gas bubbles generated during the process of electrolysis improperly are used. The paper presents the use of a new developed method and constructed electroflotator for lakes green water and industrial wastewaters disposal using the negatively charged with calculated dispersiveness of hydrogen bubbles and special electroflotator construction in the process of electroflotation.
