Abstract

The invention discloses a self-lifting water quality purification device applicable to still water lakes. The device comprises a floating island basal body, an air pump, an ecological purification box, floating troughs, an air delivery pipe and an aeration device, wherein the floating island basal body floats on the water surface and aquatic plants are planted on the floating island basal body; the ecological purification box is in a water permeable structure, and substances used for microbial degradation and physical filtration and adsorption are arranged in the ecological purification box; the ecological purification box slides up and down along the air delivery pipe; and the aeration device is arranged below limit switches, is connected with the lower end of the air delivery pipe and is used for delivering oxygen to lake water and the floating troughs. The device has the beneficial effects that integration of plant absorption, microbial degradation, physical filtration and adsorption and oxygenic aeration of the lake water is achieved via the aquatic plants, the ecological purification box and the aeration device; the invention aims to solve the problem that common floating beds have poor still water bottom layer purification efficiency; and three-dimensional purification of the still water is achieved by the self-lifting purification device to gain better water quality purification effects.

Description

technical field [0001] The invention relates to a self-elevating water quality purification device suitable for lakes with still water, belonging to the technical field of water environment protection. Background technique [0002] Lakes are the largest freshwater reservoirs on earth, and 90% of available surface freshwater resources are stored in lakes. With the rapid development of my country's economy in the past 30 years, the scale and speed of the development and utilization of lake resources have been continuously enhanced, which not only affects the natural evolution process of lakes, but also causes serious damage to lake ecosystems. The results of the evaluation of the nutritional status of 84 representative lakes in the country show that 44 lakes are in a state of eutrophication throughout the year, accounting for 52.4% of the total number of evaluated lakes, and the rest of the lakes are in a state of mesotrophic. Pollution control has become the focus and difficu...
