    铅板中铅的泄漏应急处理!
    来源: 发布时间:2020-01-19

      把火关掉。戴上防毒面具,穿上一般的防火衣物。用干净的铲子收集在干燥干净的有盖容器中,用水泥、沥青或适当的热塑性材料固化,然后丢弃。如果有大量的泄漏,收集起来进行回收或无害处理。
      Turn off the fire. Put on gas mask and ordinary fireproof clothes. Collect with a clean shovel in a dry, clean covered container, cure with cement, asphalt, or suitable thermoplastic material, and discard. If there is a large amount of leakage, collect it for recycling or harmless treatment.
      对于泄漏的PbCl4和Pb(ClO4)2,应穿戴所有防护设备,如防毒面具。与干燥的砂土混合,小批量注入大量的水,稀释污水进入污水处理系统。
      For leaking PbCl4 and Pb (ClO4) 2, all protective equipment, such as gas masks, should be worn. Mix with dry sand, inject large amount of water in small batch, dilute sewage into sewage treatment system.
      对于泄漏的PbO、四甲基(b)铅和Pb3O4,应穿戴防毒面具等防护用品。混合干沙子,倒入一个开放的空间埋葬它。被污染的地板用肥皂或清洁剂清洗,稀释后的污水进入污水处理系统。
      For the leaked PbO, tetramethyl (b) lead and Pb3O4, gas masks and other protective articles shall be worn. Mix the dry sand and pour into an open space to bury it. The contaminated floor shall be cleaned with soap or detergent, and the diluted sewage shall enter the sewage treatment system.
      对于漏气的PbF2,应穿戴防毒面具等防护用品。洒上苏打粉;被污染的地面用水清洗,稀释后的污水进入污水处理系统。
      For PbF2 with air leakage, gas masks and other protective equipment shall be worn. Sprinkle soda powder; clean the polluted ground with water, and dilute the sewage into the sewage treatment system.
      对于泄漏的Pb(BrO3)2、PbO2和Pb(NO3)2,应穿戴防毒面具等防护设备。污染的表面用水清洗,稀释后的污水进入污水处理系统。
    射线防护器材
      For the leaked Pb (BrO3) 2, PbO2 and Pb (NO3) 2, gas masks and other protective equipment shall be worn. The polluted surface shall be cleaned with water, and the diluted sewage shall enter the sewage treatment system.
      (5)对于泄漏的烷基铅,用不燃分散剂制成乳液擦洗。如砂土不能吸收分散剂,应将其倒入空旷地方掩埋;被污染的地板用肥皂或洗涤剂清洗,稀释的污水被添加到废水系统。
      (5) for the leakage of alkyl lead, the emulsion is scrubbed with non flammable dispersant. If the sand can not absorb the dispersant, it should be poured into the open place for burial; the polluted floor should be cleaned with soap or detergent, and the diluted sewage should be added to the wastewater system.
      处理方法:当水受到污染时,可采用中和处理,即加入石灰乳调节pH至7.5,使铅以氢氧化铅的形式从水中沉淀到污泥中。机械搅拌可加快澄清速度,净化效果80% ~ 96%,处理水中铅的浓度为0.37 ~ 0.40mg/L。污泥经过无害化处理。对于铅污染土壤,可以通过添加石灰、磷肥等改良剂来降低土壤中铅的活性,减少作物对铅的吸收。
      Treatment method: when the water is polluted, neutralization treatment can be adopted, i.e. adding lime milk to adjust the pH to 7.5, so that the lead can be precipitated from the water to the sludge in the form of lead hydroxide. Mechanical agitation can accelerate the clarification speed, the purification effect is 80% - 96%, and the concentration of lead in the treated water is 0.37-0.40mg/l. The sludge is treated innocuously. For the lead polluted soil, we can reduce the activity of lead in the soil and the absorption of lead by crops by adding lime, phosphate fertilizer and other modifiers.
