How to deal with a large amount of sludge and waste water treatment after sand washing is one of the problems faced by many sand factory owners. With the increase of sand field, a large amount of mud and sludge will be produced in sand making and sand washing in sand field, which will lead to mud splashing everywhere and pollute the environment.
For waste water treatment for sand washing plant, LDHB filter press can achieve rapid dehydration treatment. The mud is pumped to the equipment for filtration, extrusion and dehydration. The mud cake is pressed out and the water can be recycled. The whole set of equipment is easy to operate and can operate for a long time, achieving the effect of high output and low energy consumption.
LDHB also have a slurry treatment system to deal with a large amount of sludge after sand washing. Mud purification is to purify and reuse the pile driving mud generated in urban infrastructure construction. The sand in the mud is extracted by screening, washing and recycling equipment to obtain the purified mud, and then the mud is pressed into mud cake by the filter press to realize the dry stacking and drainage of mud and the reuse of water. Some mud can also be reused in piling operation.
Advantages of LDHB waste water treatment process
1.The investment is small and the floor area is small. At the same time, it can reduce the damage to the equipment components and prolong the service life of the equipment.
2.Slurry treatment system, mud water separation and solid waste dry discharge have clear steps and detailed division of labor. Each machine has unique structural design to ensure that it can play its role to a large extent, so as to achieve a simple purpose.4. The filter press adopts the fully automatic program-controlled pulling plate technology, and the pressure gauge and overpressure protection reflux device are installed at the feed inlet to effectively protect the equipment components and filter cloth from overload.
3. Structural optimization, overall modular design, free combination, convenient maintenance and transportation.
4. The internal structure of the paste thickner body is designed according to the principle of fluid dynamics, and the factors such as turbulence and sedimentation are fully considered. Under the same treatment capacity, the volume is smaller and the dosage of flocculant is less
