Device and process for treating mine ammonia nitrogen wastewater by series parallel graded adsorption and reverse osmosis |
| abstract |
A device and a process for treating mine ammonia nitrogen wastewater by series parallel fractional adsorption and reverse osmosis comprise a fractional adsorption system, a wastewater adjusting system and a reverse osmosis system; the graded adsorption system comprises a main water inlet pipe (10) and one-to-four stages of activated carbon adsorption cylinders which are sequentially connected in series; the wastewater adjusting system comprises an adjusting tank (5) and a cartridge filter (6), and the reverse osmosis system comprises a reverse osmosis membrane assembly (7), a filtered water collecting tank (8), a backwashing device and a treated water discharge pipe (81); the device realizes the cyclic treatment of the ionic rare earth mine wastewater with large ammonia nitrogen concentration span by utilizing the adsorption effect of the four-stage camellia oleifera shell activated carbon and the separation effect of the reverse osmosis system, is easy to disassemble and carry, has no wastewater discharge when the operation of each system is mutually switched, is more suitable for mines, namely places with remote geography and inconvenient transportation, reduces the infrastructure cost, and can realize the cyclic utilization of solid wastes by taking the biological camellia oleifera shell activated carbon adsorbing ammonia nitrogen as a soil fertility intensifier. |
