Embodiment 1
[0057] This example simulates the inclusion of acidity, Fe 2+ , Mn 2+ , Cu 2+ , Pb 2+ , Zn 2+ , SO 4 2- A permeable reaction wall unit with a width of 50cm for each level of the tank body was built for the low-concentration mine-cave acidic wastewater solution with equal pollution factors (as shown in Table 1), and a simulation experiment was carried out. The above-mentioned waste water was added to the front end of the simulated mine tunnel plugging unit. Under the condition of a flow rate of 1 L / min, the wastewater drawn from the mine tunnel drainage pipe 5 was treated by a multi-stage reaction tank, and the water quality of the effluent tank was analyzed. Among them, the content of pollution factors has reached the Class III standard of "Environmental Quality Standard for Surface Water" (GB3838-2002). It shows that the system has excellent purification and treatment capacity for low concentration mine water. The system can reduce and harmlessly treat the water gushin...
Embodiment 2
[0060] This example simulates the inclusion of acidity, Fe 2+ , Mn 2+ , Pb 2+ , Zn 2+ , SO 4 2- A high-concentration mine cave acid wastewater solution with equal pollution factors (as shown in Table 2), a permeable reaction wall unit with a width of 50cm for each stage of the tank was built, and a simulation experiment was carried out. The above-mentioned waste water was added to the front end of the simulated mine tunnel plugging unit. Under the condition of a flow rate of 1L / min, the wastewater drawn from the mine tunnel drainage pipe was treated in a multi-stage reaction tank. The content of pollution factors has reached the "Technical Specification for Sewage Treatment of Iron Ore Mining and Dressing Enterprises (GB / T33815-2017). It shows that the system has a good ability to purify the high concentration mine water. The system can reduce and harmlessly treat the water gushing from the mine.
