Solar water quality improving machine

Abstract

The invention provides a solar water quality improving machine. The solar water quality improving machine comprises a solar power assembly, a bottom layer flocculent sludge absorption and discharge assembly, floaters, and a moving and controlling assembly, wherein the floaters are respectively used for bearing the solar power assembly and the bottom layer flocculent sludge absorption and discharge assembly; and the two floaters are integrally connected into a whole through a connection rod. According to the solar water quality improving machine provided by the invention, the solar power assembly, the bottom layer flocculent sludge absorption and discharge assembly and the like are assembled together by using solar photovoltaic power; flocculent bottom mud at a bottom layer of a water body is absorbed and discharged to a surface layer of the water body by using the solar photovoltaic power; the discharge amount of flocculent sludge at the bottom layer is controlled by using the illumination as a condition index, so that the sedimentation of the bottom mud of the water body is reduced; organics decomposition and nutrient release in the sludge can be promoted; the nutrient balance of the water body is adjusted; the water quality is improved; the sedimentation pollution is reduced; and the level of productive capacity of the water body is improved.

Description

technical field [0001] The invention relates to the field of water pollution control, in particular to a water body bottom quality improvement control device. Background technique [0002] Studies have found that, except for 20% to 30% of the nutrients such as nitrogen and phosphorus input into the water body are absorbed and utilized by aquatic organisms, the rest all enter the water body environment, and about 60 to 70% of them are deposited in the bottom mud. On the one hand, the existence of a large amount of organic matter in the sediment of the water body not only leads to sediment deposition, but also produces reduced substances such as ammonia nitrogen, nitrite, methane, hydrogen sulfide, etc., causing deterioration of water quality and seriously affecting the safety of the water environment. On the other hand, the sediment of the water body is also a nutrient pool, and a large amount of nutrients needed for the primary productivity of the water body come from the se...

Problems solved by technology

Mechanical dredging mainly uses hydraulic pond dredging units to remove the silt at the bottom of the water body. This method cannot achieve the reuse of nutrients in the bottom mud; although the microbial method improves the resource utilization of nutrient-rich substances in the bottom mud, it cannot The effect of controlling the growth conditions of microorganisms cannot be stable; although the chemical method is quick, it is easy to cause chemical residues, and there are many problems that cannot fundamentally solve the problem
