摘　　要：采用砂滤-活性炭吸附-膜过滤-反渗透工艺,通过中试,对某铅酸电池厂现有处理出水进行深度处理的可行性进行了研究。结果表明,当反渗透系统进水体积流量10 L/min、平均电导率950μS/cm情况下,平均脱盐率96%,能耗为4 kWh/t;平均产水率为75%时,对水中Zn2+、Pb2+、Cd2+去除率的分别达到100%、96%、99%以上。反渗透处理后出淡水达到GB 3838-2002三类标准,完全达到回用水标准。采用化学药剂处理反渗透处理后的浓水,处理后的浓水可以回用到蓄电池生产的某些工段。该方法能耗低、产水率高、操作简便,系统运行稳定可靠,可用于蓄电池废水的深度处理。水深度处理的成本大约为6.5元/t。By pilot-scale experiments, the feasibility of reverse osmosis technology utilized for further treating the existing effluents from lead acid battery by adopting quartz sand filter- activated carbon adsorption- membrane filtration-reverse osmosis technique. The results show that when the inlet flow rate of reverse osmosis is 10 L/min, and average conductivity of influent is 950 μS/cm, the average desalting rate is more than 95%, energy consumption is 4 kWh/t, average water productivity is 75%, removal rates of Zinc ion, Lead ion and Cadmium ion are respectively 100%, 96% and 99% during the pilot-scale experiment. The quality of treated freshwater can reach Surface Water Three Categories Standard （GB 3838 -2002） and completely meet the recycling demand. The chosen chemical agents are added to RO concentrated water; the treated concentrated water can be recycled to certain procedure. Furthermore, the researched method is characterized by low energy consumption, high water productivity and simple, reliable and stable operation. It can be used for the desalination and removal metal ion treatment treating existing effluents from Lead acid battery corporation in order to recycling the water resource. The expenses of treating was 6.5 yuan/t.
