Strong Attack，New Mud Treatment Equipment For Sand
2021-09-08
Mud treatment equipment in the sand field is very important! Because a certain amount of mud wastewater is generated during the production process of the gravel yard, although this type of wastewater will not cause chemical pollution to the environment, the suspended solids (SS) specified in the first level discharge standard of the national comprehensive sewage discharge standard: ≤ With the requirement of 70mg/l, the suspended solids (about 3% to 10%) such as mud (powder) in the wastewater exceed the standard. If this type of wastewater is directly discharged, it will adversely affect the surrounding water environment and surrounding farmland, and residents’ lives.
In the early days when the sludge treatment technology was not perfect, the main treatment method of piled sludge was landfill and natural drying. However, over time, the original method is far from being able to meet the increasing requirements for silt treatment in the sand field. As the country pays more and more attention to environmental protection, higher requirements are put forward for the treatment of muddy sewage. So how to effectively deal with silt has become a difficult problem in engineering construction?
LZZG can rationally design the sand yard mud treatment process according to the type of raw materials, mud content, hourly water volume, site conditions, etc. of the customer’s sand and gravel yard. Fully consider factors such as flocculation, sedimentation, etc., the wastewater is purified through a rapid concentration process, and the overflowing clear water is recycled for reuse, and the sedimented thick slurry is press filtered and dehydrated into a dry mud cake.
Process steps of mud treatment equipment in sand field
After the mud enters the underground mud pool, it is pumped by a vertical pump into the lower sieve surface of the vibrating screen of the mud processor. The particles (coarse sand) with large sieve holes are directly dehydrated and discharged from the discharge port. Small materials enter the water tank under the screen and then are pumped into the separator through a slurry pump (4/3) inside the mud processor. The bottom flow of the separator enters the upper sieve plate of the vibrating screen to produce small fine sand. The return water from the separator enters the return water tank and flows into the trihydrogen purification body by itself. The thick mud flocculated by the trihydrogen purifier is pumped by the special pump of the filter press, pumped into the chamber filter press, and filtered into a mud cake by the filter press to be discharged. At the same time, the trihydrogen purification body overflows the clean water, and the clean water filtered by the filter press is returned to the clean water turret, to realize the recovery and efficiency of fine sand, dry solid waste treatment, and reuse of water resources.
The whole processing equipment adopts structural modular design, free combination, convenient for repair and transportation. It can achieve resource reuse and meet environmental protection requirements. If you need such environmentally friendly machinery and equipment, you can call us or visit the factory on-site. We will have a dedicated salesman to receive you.
