以镇江市征润州水源地突发铅污染为背景,研究了活性炭吸附、混凝沉淀工艺对不同超标倍数下铅污染的应急处理效果.小试实验结果表明:PAC可有效应对超标5倍、10倍的低浓度铅突发污染,分别投加5和10 mg/L PAC,出水铅浓度即可达标;而针对高浓度的铅突发污染, PAC处理能力有限.混凝沉淀实验结果表明:针对超标5 倍的铅污染,投加120 mg/L Ca( OH) 2 即可达标处理;针对超标10倍的铅污染,最佳Ca( OH) 2 的投加量为80 mg/L;而针对50倍和100倍的铅突发污染,最佳Ca( OH) 2 的投加量为120 mg/L.在最佳Ca( OH) 2 投加量下,针对超标10倍、50倍和100倍突发污染,最佳聚合氯化铝投加量为5、30和35 mg/L.通过实验室小试研究,为可能突发的铅污染事故应急处理提供了技术支持.

In the background of lead pollution occurred suddenly in ZhengRunzhou water source, the emergency treatment efficiencies of different pollution levels by were studied powdered activated carbon ( PAC) adsorption and coagulation sedimentation process.The jar test results showed that PAC can effectively respond to lead pollu-tion of exceeding 5 times and 10 times of standard value by adding 5 mg/L and 10 mg/L of PAC respectively, the effluent concentration could be up to standard.For high levels of lead pollution emergency, the removal abili-ty of PAC was limited.Coagulation sedimentation experiments showed that, for lead contamination exceeding five times, through adding 120 mg/L calcium hydroxide, row water could be treated to standard limit value, while the optimum calcium hydroxide dosage was 80 mg/L for 10 times lead contamination.For 50 times and 100 times lead sudden pollution, optimal calcium hydroxide dosage was 120 mg/L.At the best calcium hydroxide dosage, for 10 times, 50 times and 100 times overproof sudden pollution, the optimum dosage of PAC were 5 mg/L, 30 mg/L and 35mg/L respectively.The jar test research provided technical support for a possible sudden lead pollu-tion emergency treatment.
