Pay attention! This wire saw machine is cutting marble. The Diamond Wire Saw keeps cutting the stone through high - speed movement. To reduce the heating problem of the wire saw caused by high - speed cutting, the workers have set up three cooling water injection points respectively. The continuous supply of cooling water enables the diamond wire saw to maintain high - efficiency cutting during high - speed cutting operations. However, this also results in a continuous generation of sewage. How to effectively treat this sewage is an issue that every quarry should consider at the beginning of designing the quarrying plan.

Hello, everyone. I'm Oliver Mo, who produces and sells wire saws. Will the sewage generated by stone quarrying equipment such as wire saw machines during the stone quarrying process cause environmental pollution? The answer is yes. The sewage generated during stone quarrying and processing contains high - concentration suspended solids (such as stone powder particles), heavy metal ions (such as iron and manganese), and weakly alkaline substances. If directly discharged without treatment, it will disrupt the ecological balance of water bodies, lead to soil compaction, cause the death of aquatic organisms, and may result in high fines for violating the "Water Pollution Prevention and Control Law". Direct discharge of sewage not only causes environmental pollution but also leads to a great waste of water resources. If this cooling water is treated and recycled, the production water cost can be reduced (ideally, about 30% - 50% of water resources can be saved). Long - term discharge of high - turbidity sewage can block rivers, affect groundwater safety, and pose a threat to the health of surrounding residents.

For the larger - sized stone powder and slag (such as particles with a diameter > 0.5mm) in marble processing wastewater, more than 80% of the suspended solids can be removed directly by the natural sedimentation method (such as a horizontal sedimentation tank). However, if the concentration of suspended solids in the wastewater is extremely high or it contains colloidal particles, the coagulation - sedimentation process needs to be combined for treatment. What is the coagulation - sedimentation process? The coagulation - sedimentation process is a water treatment technology. It refers to adding a coagulant to make the suspended solids and colloidal substances in the water coagulate into larger particles for subsequent treatment. It mainly includes three steps: coagulation, sedimentation, and filtration. Simply put, it's like making tofu. The sewage treatment in quarries must be taken seriously. Many bosses think that since the quarry is located in a remote area, the sewage can directly seep into the ground without being noticed. Little do they know that this is a huge hidden danger for the entire quarrying enterprise. At best, it may lead to complaints and inquiries from local residents. At worst, it may attract strict inspections from environmental protection departments, and ultimately, the enterprise will bear corresponding legal responsibilities for its actions.

Finally, I'm Oliver Mo, who produces and sells wire saws. I hope to be your partner on the stone quarrying journey. See you in the next video.
