摘要
Abstract
According to the quality of washing wastewater from deposited ammonium carbonate(WWDAC) discharged from a rare-earth smelting plant,using NH4 C1 and NaCl simulated wastewater batch experiments were conducted to investigate the feasibility of the treatment by reverse osmosis.Simulation experiments indicated that under the identical conditions there was higher removal efficiency for treating NaCl by reverse osmosis,compared to NH4 Cl.However,NH4 Cl in comparison with NaCl has a higher production rate of water.The result of actual wastewater experiment demonstrated that under the conditions of a constant pressure range and a recovery rate of 65%.the removal efficiency of WWDAC with an NH4 Cl concentration of 2.85g/L treated by RO was 77.3%.The RO treatment could be used as pretreatment of ammonium nitrogen.An analysis showed that the operational cost of wastewater treatment was about 2.7 yuan/m3.About 26% of the wastewater treatment costs could be saved compared to that of ammonium nitrogen wastewater with a close concentration by ammonia stripping.关键词
