step two, digging sludge at the bottom of the river and lake to a sludge stirrer;
removing lumps with large particle sizes such as stones doped in the sludge through a vibration grid on the sludge stirrer;
step four, conveying the curing agent into a sludge stirrer through pumping equipment, and stirring and mixing the curing agent with sludge to obtain composite sludge slurry;
