The water carrying capacity (V) of the rubber water tank is less than or equal to the buoyancy (F) generated by the heat insulation shed body on the plastic shed minus the net weight (G) of the plastic shed. After the rubber water tank is filled with water, the weight (W) of the plastic shed is larger than W = V + G, the buoyancy force received by the plastic shed in the lifting process is (F), F is less than or equal to F, and the weight W of the plastic shed is larger than F, so that the plastic shed sinks and enters water. After water in the rubber water tank is drained into the plastic shed, the water level in the plastic shed is slightly higher than the water level outside the plastic shed, a water inlet pipe orifice of the plastic shed is placed into the water, the plastic shed starts draining, the weight of the plastic shed in the draining process is set as (W), G < W ≦ W, the weight of the plastic shed during draining is set as (W), so that the plastic shed rises, when the weight of the plastic shed is W = G = f, the plastic shed stops draining and rising, and the natural draining of the plastic shed is finished.
Secondly, the water in the shed is heated to reduce the content of dissolved oxygen in the water. The water temperature is originally high in summer, the water temperature in the greenhouse is increased by about 1 ℃, the metabolism of plankton in water in the greenhouse is accelerated, the oxidative decomposition of organic matters in the water is accelerated, the consumption of dissolved oxygen in the water is increased, and the water in the greenhouse is not exchanged with the water outside the greenhouse, so that oxygen deficiency is generated at the bottom of the greenhouse.
Thirdly, the water in the shed is covered tightly by black plastic cloth to eliminate oxygenation. The black plastic cloth is tightly attached to the water surface in the shed to be airtight, so that oxygen in the air is blocked and cannot enter water in the shed, and the natural oxygenation of the air to the water body in the shed is eliminated; the black plastic cloth is light-tight, so that the phytoplankton in the water in the shed can not be subjected to photosynthesis to generate oxygen, the self oxygenation of the water body in the shed is eliminated, under the closed condition of higher water temperature, the original dissolved oxygen in the water in the shed is quickly consumed by plankton and organic matters, and the water body in the shed is lack of oxygen, so that all the plankton in the water die.
Fourthly, the sediment is collected by utilizing the difference between the water levels inside and outside the plastic shed. The dead back deposit of plankton of plastics canopy aquatic is at the bottom of the canopy, because rocking of plastics canopy in aqueous, makes the deposit gathering at the bottom of the canopy the lower, also be exactly drainage opening department, and the drainage mouth of pipe puts into the aquatic and makes the inside and outside water phase of canopy open, because the water level is a little higher than outer water level in the plastics canopy, outside the canopy is discharged to the water integument in the canopy, collects the discharged deposit with the bolting-silk bag.
