【摘要】：以反渗透作为主体工艺进行突发自然灾害应急水处理工艺研究,在试验浓度范围内,反渗透工艺对浊度、CODMn、氨氮和盐类物质的平均去除率分别达99%,90%,87%和96%.对镉、铅、镍、铜4种常见重金属离子的去除效果显著,平均去除率分别达96%,97%,96.5%,96%.对乙苯、二甲苯、氯苯、1,2-二氯苯、1,4-二氯苯、2,4,6-三氯酚、三氯乙酸、三氯乙醛以及乐果、灭草松、草甘膦、敌敌畏、百菌清、毒死蜱6种典型农药的去除效果较好,平均去除率分别达98.51%,98.46%,97.84%,99.03%,99.11%,99.56%,99.24%,99.29%,99.16%,99.98%,99.95%,99.76%,99.61%,99.67%;对三氯甲烷、三溴甲烷、苯酚、苯乙烯的去除效果一般,平均去除率分别为73.43%,86.03%,72.64%,63.31%;对苯、二氯甲烷、甲醛的去除效果较差,平均去除率分别为44.36%,17.57%,8.37%.在试验研究的基础上,提出应急水源地水质建议性标准,为突发性水污染反渗透处理工艺的实际应用提供了参考依据.
[Abstract]:Using reverse osmosis as the main process, the emergency water treatment process of sudden natural disaster was studied. In the range of experimental concentration, the average removal rates of turbidity, ammonia nitrogen and salt substances by reverse osmosis process reached 9990% and 96% respectively. For cadmium, lead and nickel, The removal efficiency of four common heavy metal ions was significant, with the average removal rate of 960.The average removal rate was 960.Para-ethylbenzene, xylene, chlorobenzene 1, 2-dichlorobenzene, dichlorobenzene, trichlorophenol, trichloroacetic acid, trichloroacetic acid, dimethoate, methoxylasone, glyphosate, dichlorobenzene, dichlorobenzene, dichlorobenzene, dichlorobenzene, dichlorobenzene. The average removal rates of chlorpyrifos and chlorpyrifos were 98.51g, 98.46 and 97.84, respectively. The average removal rates were 73.4343 and 86.0372.647.31, respectively. The average removal rates of chlorothalonil, chlorpyrifos and chlorpyrifos were 73.4343, 86.0376.0372.63.31 and 63.31, respectively, and the average removal rates of chlorothalonil, chlorpyrifos, chlorpyrifos and chlorpyrifos were 99.116.5699.5699.2999, 99.9859, 99.95um 99.661, 99.6167, and the average removal rates of trichloromethane, tribromomethane, phenol and styrene were 73.4343, 86.03 and 86.0372.643.31, respectively. The removal efficiency of formaldehyde is poor, the average removal rate is respectively 44.36 and 17.577.On the basis of experimental study, the suggested standard of water quality in emergency water source area is put forward, which provides a reference for the practical application of reverse osmosis treatment process for sudden water pollution.
