The construction site is located in Yongsheng, Lijiang. The material used is 2.0HDPE geomembrane, which is a single-sided column point type. The paving areas are 1,700 square meters, 1,100 square meters and 900 square meters respectively, totaling 3,700 square meters. Because of the loss during construction, the actual use is about 3,600 square meters. The equipment used is 1 welding machine, 1 extrusion welding machine, 8 auxiliary construction workers and 2 technicians.
The construction of the ore washing filter pool is actually not much different from the construction of the reservoir. It only needs to be laid according to the normal process, but the site cleaning needs to be done in place, that is, no gravel, branches and sharp objects should be left in the site. The ore washing water is usually circulating water. Its entire circulation process is to drain the ore washing sewage to the reagent pool, separate the mud and water through the reagent, and then introduce the surface clean water into the pool. This is why multiple pools are needed for coordinated treatment.
After a long period of use, the silt in the ore washing pool needs to be cleaned. Therefore, we can consider pre-burying sewage pipes during construction to make the remaining silt easy to handle, because manual cleaning may cause damage to the membrane material.
