高效重金属去除剂（EMRA）说明书
High efficiency of heavy metal removal agents ( EMRA )
一、 简介与特性
One, introduction and characteristics
高效重金属去除剂EMRA是一种专门针对金属废水的一种含有羟基、羧基、醛基及多功能团的化合物。与重金属废水反应，适用于铜、镍、锌、铅、镉、三价铬等多金属，具有反应迅速、重金属去除率高、投药量小、反应条件温和的特性。
Efficient removal of heavy metal from agent EMRA is a specific metal wastewater containing hydroxyl, carboxyl, aldehyde and multiple functional group compounds. With the heavy metal wastewater, applied to copper, nickel, zinc, lead, cadmium, chromium and other metals, has rapid response, heavy metal removal rate is high, small dosage, mild reaction conditions and characteristics.

三、使用方法
Three, the use of methods
一般使用前需要先将20倍浓缩液进行稀释，稀释成1%-2.5%，然后把稀释好的药剂加到含重金属的废水中，充分搅拌，立即就会出现絮状泥渣，为加速沉淀，可以适量补加铝盐，加速泥渣成渣。一般加药量与废水中金属离子浓度成正比，实验室数据，20mg/l（或10PPM）的金属离子浓度，加入2%的药剂1ml，基本总金属离子浓度都低于0.1mg/l（或0.1PPM），超过国家一级金属离子浓度的达标要求。
In general use before 20 times concentrated solution is diluted, diluted to 1%-2.5%, and then diluting the good medicine to heavy metal containing wastewater, stirring, immediate flocculent sludge, in order to accelerate the precipitation, the amount can be added with aluminum salt, accelerated sludge slagging. General dosage and concentration of metal ions in wastewater by proportional, laboratory data, 20mg/l ( or 10PPM ) of the metal ion concentration, adding 2%. 1ml, basic general metal ion concentration is lower than 0.1mg/l ( or 0.1PPM ), more than the national level the standard requirements of metal ion concentration.
所加药剂的量，根据废水中含有重金属离子的浓度来确定，金属离子浓度高，所需要加的药剂量大，反之也成立。一般处理一吨废水的成本约1-4.5元每吨。
The addition of chemicals according to the amount of waste water containing heavy metal ions, the concentration of metal ion concentration, high, with the required large doses, and vice versa. General treatment of one ton of waste water costs about 1-4.5 yuan per ton.
四、 包装与贮存
Four, packing and storage
高效重金属去除剂EMRA采用塑料桶包装，每桶20kg，20倍浓缩液或标准液。贮存远离重金属盐、还原性物质，注意被污染，贮存期为十二个月。
High efficiency of heavy metal removal agent EMRA packaging plastic barrels, a barrel of 20kg, 20 times concentrated liquid or standard solution. Store away from heavy metal salts, reductive substances, attention is pollution, storage period of twelve months.
五、 安全与防护
Five, security and protection
高效重金属去除剂EMRA，带微碱性，操作时注意劳动保护，稀释溶药过程中佩戴劳动防护品，应避免与皮肤、眼睛等接触，接触后用大量清水冲洗。
Efficient removal of heavy metal from agent EMRA, with a slightly alkaline, operation attention to labor protection, dilution medicine dissolving the wearer during labor protection products, should be avoided with the skin, eye contact, contact after rinse with plenty of water.
