Sludge treatment process description
1. Through the flocculation experiment to determine the type of matching flocculant and dosing ratio. If two flocculants are required for effective flocculation, it is advisable to select a dewatering machine with two flocculating tanks. Sludge pool to set the mixing device, sludge dewatering machine in the operation and before the operation, to continue to stir the sludge to ensure that the sludge concentration is relatively stable.
2. Before running the sludge dewatering machine, should first use the bubble device to make a good flocculant solution. Wherein the normal dilution factor of the high molecular flocculant is 500-1000 times. Sludge through the sludge transfer pump, soaked flocculant through the dosing pump, according to the corresponding proportion of the same time into the flocculation mixing tank, through the mixer to fully mix to form alum, concentrated in the concentration of gravity, the filtrate from Concentrated part of the filter in the discharge. The filtrate has a low solid content and is returned directly to the original pool.
3. After the concentration of the sludge along the spiral axis forward, under the action of a variety of joint in the dehydration of the full dehydration. Dehydration of the filtrate with high solid content, can be refluxed into the flocculation tank again dehydration.
4. After the dehydration of the cake from the cake discharge, directly or through the shaftless screw conveyor to the mud transport vehicles, re-use.
