The water inlet of the main water inlet tube of flushing device, makes sparge pipe timing, metered injection flow, and control sparge pipe is 0.018 per hole flow~
0.040m3/ h makes flow from fine sand layer interior flushing fine sand, by the pollutant inside husky bottom gradually recoil to fine sand layer surface or
It is suspended in fine sand layer superjacent waters；Flow rotation collection device is run simultaneously at this time, and porous nano pipe sprays gas, and air-flow gushes
Go out, upward gas flow draining, water is spread around, and under the obstruction of aquaculture pond inner wall, flow makees directed flow, entire to make
Culturing pool moves in a circle, and controls air-flow, and it is 0.15~0.35m/s to make surface layer water velocity, and flow drives in water and oozes out
The dirt of fine sand layer surface moves in a circle, and the rotation center area of flow is gradually collected under the action of centripetal force, is fallen into foster
It grows near the Central Drainage hole of pond, while draining, flow drives dirt to be discharged outside aquaculture pond by aquaculture pond Central Drainage hole,
Realize automatic pollutant removal；
While automatic dirt cleaning device is run, probiotics-brown sugar mixed liquor is added；Adding method is as follows：The probiotics is bud
Spore bacillus 1 × 109~1 × 1010Viable bacteria unit (CFU)/L and lactic acid bacteria 1 × 109~5 × 109CFU/L, the 3~5g/ of brown sugar
They are placed in bucket the volume for mixing and adding water to needs by L, then 5~6h of aeration activation, and after screen filtration, EM is added
Bacterium 1 × 109~5 × 109CFU/L, by 1L/m3This kind of probiotics of water body full pool spilling head-brown sugar mixed liquor, splashes 1~2 time daily；
After water quality indices stabilization, it is changed to splash weekly 1~2 time；And in the breeding process of Marsupenaeus japonicus, according to cultivation
Water color, water quality indices determine the additive amount and addition frequency of probiotics-brown sugar mixed liquor, then be aided with adjusting it is secondary into
The switch of water pipe and secondary air inlet pipe, control air-flow, flow size, make entire aquaculture pond stable for extended periods of time state.
2. Marsupenaeus japonicus aquaculture pond dirt automatic pollutant removal method as described in claim 1, which is characterized in that the EM bacterium are nitre
Change bacterium, actinomyces or lactic acid bacteria.
