一体化设备处理某乡镇微污染地下水工艺研究

Study on Treatment Process of Town Micro-polluted Groundwater by Integration Equipment

针对乡镇地下水微污染的特点,研究石英砂-沸石过滤器、膜组件与紫外线消毒器一体化设备处理效果,当进水浊度在15～36 NTU,出水浊度达0.2～0.5 NTU,去除效率达98%～99.3%;进水氨氮浓度范围为0.4～1.4 mg/L,反应3.5 min后出水的氨氮浓度小于0.5 mg/L;微生物指标去除率为100%。采用一体化设备处理乡镇微污染地下水可行。

Focusing on the characteristic of town micro - polluted groundwater, this paper studied the treatment effect of inte- gration equipment which combined quartz sand - zeolite filter, membrane and ultraviolet sterilizer. When influent turbidity was at 15 -36 NTU, the effluent turbidity was at 0. 2-0. 5 NTU and the removal ratio could reach 98% -99. 3%. When influent am- monia nitrogen concentration was 0.4 - 1.4 mg/L, the effluent ammonia nitrogen is lower than 0. 5 mg/L after reaction time of 3.5 min. The removal ratio of microorganism could reach 100%. So it is feasible to treat town micro - polluted groundwater with integration equipment.
