Embodiment Construction

[0048] The present invention will be further described below in conjunction with specific embodiments.

[0049] Taking a black and smelly river course as an example, the bottom mud of the river section is aerated and repaired by using the liftable rotary aeration device of the present invention.

[0050] First, the aeration pump 2 , the solar cell 3 and the storage battery 4 are fixed on the supporting floating bed 1 . The aeration pump 2 is sequentially connected with the aeration pipe 5 and the intake cover 81, and fixed with a throat hoop. Similarly, the buoyant air bag 6 is connected with the air compressor and the rotating aeration disc 8. Adjust the telescopic rod of supporting leg 7 to make the aeration device placed stably, the distance between the rotating aeration disk and the ground is 10cm, and then inflate the buoyant air bag. Place the rotating aeration disc 8 and the supporting floating bed 1 in the river channel in sequence, and after moving to the target poi...

Abstract

The invention discloses a liftable rotating aeration device for strengthening river sediment oxygen enrichment. The liftable rotating aeration device is characterized in that a solar photovoltaic power generation system and a storage battery form a power supply system; the power supply system can supply power to an aeration pump during daytime and nighttime; the aeration pump is connected with a rotating aeration disc; the aeration disc is of an oblate bottomless shell structure; the aeration disc and a conical body vertically arranged at the center of the circle center of the aeration disc form an integral body; a check valve is arranged inside the conical body; the rotating aeration disc is made from PTFE; the waterproofness is high and the mechanical loss is small; a rotating impeller and grids/diversion holes are further arranged inside the rotating aeration disc; the head loss is small; when the aeration pump is started, the rotating aeration disc operates, air is uniformly diffused to the sediment surface layer in a service region in a spiral manner, the sediment oxidation reduction electric potential is remarkably improved, and anaerobic odors are effectively controlled; and during the intermittent period, the aeration disc can be floated upwards to be maintained. The liftable rotating aeration device can be further combined with other ecological floating beds, the application range is wide, and the liftable rotating aeration device is utilized in a water body for a long time to guarantee self-cleaning capacity of the water body and strengthen river sediment oxygen enrichment.

Description

technical field [0001] The present invention relates to water environment ecological restoration equipment, in particular to a high-uniformity, high-convenience, and high-adaptability device for improving the release potential of river sediment pollutants and the micro-ecological environment. In-situ aeration device for enriching oxygen in nutrient river sediment. Background technique [0002] With the continuous improvement of tail water quality requirements of sewage treatment plants, strict control of industrial sewage discharge, and the reduction of non-point source pollution by the construction of sponge cities, the proportion of point source and non-point source pollution in polluted rivers has gradually decreased, while endogenous pollution (bottom source pollution) The importance of mud release) control is emphasized. There are a large amount of polluting organic matter and nutrient salts in the sediment of the river channel, which are controlled by the water body-s...
