[0032] (2) When the regulating tank is discharging sand, when the water level reaches the minimum level, turn off the sewage pump 3 and stop pumping sewage; turn off the water inlet pipe 9 and turn on the ion deodorization device 13 to purify the air in the regulating tank; turn off the plug flow agitator 2, turn on the flushing pump 15, and the sewage from the sump 19 enters the branch pipe through the main pipe of the flushing water pipe 8 and passes through the flushing nozzles at different elevations to flush the pool wall. The flushing sewage is collected in the sump through the drainage trough 5 to ensure the continuous circulation of the flushing water source and supply water to the flushing pump 15; after the flushing water pipe 8 has flushed the pool wall, the flushing water pipe valve is closed. Door 17, flushing water pipe 8 stops flushing, and ejector 1 is turned on. The ejector 1 can be remotely controlled to rotate and move to perform multi-angle and comprehensive flushing of the mud and sand at the bottom of the regulating tank; the flushing sewage is collected into the sump 19 through the drainage trough 5 to ensure the continuous circulation of the flushing water source and supply water to the flushing pump 15, the ejector 1 and the flushing pump 15 are closed, the sand discharge pump 4 is turned on, the mud and sand water in the sump 19 is extracted, and it is pumped to the sand washing machine 12 through the sand discharge pipe 11. The sand washing machine 12 can separate the mud and sand, dehydrate the mud and sand, and return the dehydrated water to the regulating tank, and the dehydrated mud and sand are recovered.
[0033] (3) When the regulating tank is under maintenance: first, the sand removal work in the above (2) is carried out, and then the ion deodorization device 13 purifies the air in the regulating tank. After the CH4, H2S, NH3 and other gases detected by the gas monitoring instrument 18 meet the standards, the operator wears a gas mask to enter the regulating tank for maintenance to ensure the safety of the operator.
[0034] Depending on the silt blockage in the regulating pond, sand discharge and maintenance can be carried out at intervals of 30 to 60 days.
