Sludge water treatment system commonly used process two

The third stage: secondary swirl

After being treated by the primary cyclone, the slurry flows into the secondary cyclone main tank, and the slurry pump is pressurized into the secondary cyclone, and the 0.075mm-0.020mm particles in the mud are removed, and the vibration dewatering screen is dehydrated to the moisture content of about 45-50% (depending on the solid phase composition, the moisture content of the general sand and stone after dehydration is bottom, Clay silt dehydration moisture content is higher), fall to the ground pile.

Stage 4: (Mixing and pulping system)

After the sludge water is treated by the main separation equipment and then subjected to the gravity precipitation treatment of the sedimentation tank, the micro-particles above 0.020mm that have not been treated in the sludge water after secondary treatment can be more completely removed, and the particle size of the micro-particles contained in the sludge water can be further reduced, in order to meet the index requirements of the sludge water. If the slurry feeding water after the above treatment does not meet the requirements of the index, the slurry mixing materials such as the slurry configured by the mixing pulping system are added, and the monitoring (density, viscosity, etc.) and operation subsystem of the system are used to make the slurry feeding water that meets the requirements of the index for recycling of the shield. The pulping system also balances the logistics of the whole processing system.

Stage 5: (Filter press system)

After settling, the slurry is pumped into the concentration tank, and then pressurized into the filter press system by the diaphragm pump for dehydration. After dehydration, the water content of the solid particles is less than 40% compared with that of the dry, which is suitable for truck transportation.
