6. a using method for water body nano oxygen enriching system, comprises the following steps:
1) use suction pump to extract water from water body through suction hose, utilize the suction function that suction pump produces in suction hose simultaneously
Lower intake-gas, sets the pressurization of impeller in suction pump, and gas is dissolved in water, forms dissolved air water；
2) by step 1) in the undissolved excessive gas in water discharged by moisture trap；
3) by step 1) dissolved air water that obtains is after air relief valve instant decompression, and gas discharges from water, forms bubble；
4) step 3 will be swept along) water of bubble that obtains is ejected in water body, spreads, dissolves in water body, the dissolved oxygen of water body
Increased.
