The necessity of mud purification recovery
During Non-excavation directional drilling, due to the diameter of a large hole, such as West-East Gas Pipeline and Jining pipeline project, with a diameter of 1016mm steel pipe, in the reaming stage, the amount of mud is very large.( mud purification recovery)
Usually, the non-excavation drill is through the open system, in the general through, the amount of mud are more than 3000 cubic meters, and some even reach 10,000 cubic meters. The amount of mud is large, not only increases the cost of mud and land acquisition, the more serious problem is that after the completion of waste mud if not effective treatment, pollution of farmland and water will cause ecological problems.
With the enhancement of environmental awareness, it is imperative to develop and use mud purification and recovery equipment.
The slurry purification and recovery unit can carry out solid phase treatment of the returned slurry and then recycle it, on the one hand, reducing the amount of mud, reducing the pollution to the environment and reducing the amount of waste disposal. On the other hand, the recovered mud is ” maturity Mud “, the performance is relatively stable,it can reduce the performance instability caused by underground accidents, to ensure the smooth progress of the project.
