Floating type lake heavy-metal collecting device and use method therefor

Abstract

The invention discloses a floating type lake heavy-metal collecting device and a use method therefor and belongs to the technical field of biological treatment. According to the floating type lake heavy-metal collecting device and the use method therefor, a plurality of substance gathering balls with metal adsorption balls are suspended in water by means of floating, are limited through submarineload-bearing devices and meanwhile are limited through high-strength bridles, so that difficulty in collecting at a later stage caused by water flow followed fluctuation of the substance gathering balls is effectively avoided; meanwhile, the metal adsorption balls are attracted into the substance gathering balls through magnetic attraction and are subjected to centralized magnetic-attraction fixing and stacking, so that the heavy-metal adsorption balls can form an adsorption plane, and thus, the adsorption effect is improved; meanwhile, a reticular upper-hemisphere shell and a lower screen areused for filtering floating matters in the water, so that adsorption saturation of the metal adsorption balls caused by the floating matters and particulate matters is effectively avoided; and aftermetal adsorption is saturated, the metal adsorption balls easily fall into a collecting bag, and thus, subsequent collecting treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of biological treatment, in particular to a floating lake heavy metal collection device and a method for using the same. Background technique [0002] One of the biggest characteristics of shallow lakes is that the water-soil interface is constantly disturbed by wind and waves, causing a large number of surface sediments, animal and plant residues and other particulate matter to suspend and re-enter the water body. The role of water continuously interacts with water bodies, thereby affecting water quality, nutrient levels and ecological risks to aquatic organisms. [0003] Among them, heavy metals in suspended matter are a kind of conventional water body pollutants. Because of their high toxicity and non-degradable characteristics, they have become extremely harmful and have attracted much attention among water body pollutants. Collecting and studying suspended particles in water bodies The content and form...

Problems solved by technology

However, because the lake water has a certain fluidity, the floating objects and particles in the water have the characteristics of floating around. In addition, the adsorption ball has the characteristics of active adsorption, so it is easy to gather and absorb the floating objects and particles in the water. Wrapped on the surface of the adsorption balls and block the pores of the adsorption balls, resulting in the decline or even loss of adsorption performance, resulting in poor adsorption and treatment effect of heavy metals; collect it
