when the spraying and defoaming are carried out again, a second valve is opened to enable clear water to enter the mixed water tank along the second pressurization guide pipe, the reading on the water meter is observed, when the entering water reaches 300L-400L, the second valve is closed, at the moment, an adjusting valve on the defoaming agent storage box is opened again, 4 g-6 g of defoaming agent is adjusted to enter the mixed water tank, and the water and the defoaming agent are fully mixed in the mixed water tank;
opening a first valve on the mixing water tank, enabling the mixed defoaming water to enter a spray pipe, then spraying out the mixed defoaming water through a spray head, starting a rotating motor in the spraying process to drive the spray pipe to perform 180-degree rotary spraying until the mixed water in the mixing water tank is sprayed, then waiting for the reaction of bubbles in a white water tank and the defoaming water, controlling the reaction time to be 15-20 minutes, then preparing for spraying again, and further spraying 3-5 times of defoaming water;
when mixed defoaming water is sprayed each time, adding clean water into the mixed water tank each time, wherein the amount of the clean water is increased relative to the amount of the clean water at the last time, and 50L-100L of clean water is increased each time; the defoaming agent amount added into the mixing water tank each time is reduced in sequence by 0.5-1 g each time compared with the last defoaming agent amount; after the defoaming water that mixes out at every turn sprays, the bubble in the plain boiled water pond reacts with the defoaming water, and long control is in 5~10 minutes during the reaction, can carry out next defoaming that sprays until accomplishing 3~5 times defoaming water sprays.
