很多厂家对于聚丙烯酰胺在真正使用处理污水时都不是很明确，那么对此便要进行污泥或废水试验进而来确定聚丙烯酰胺的类型。但是实验时要选择具有参考价值的污泥或废水。废水或者污泥的种类都有很多，那么安家净就对废水取样进行一下说明，希望能给广大买家提供便利。
1. 如果你是选择城市污水又或者是工业废水，那么你在进行污泥药剂筛选时，取样要取污泥浓缩池中的废水，因为一般这种废水经过了之前很多道程序后各种浓度都很高。
porous or insulating materials such as boiling rocks, diatomite, perlite, sea pumice, expanded vermiculite is the difference in hardness, strength is poor, with its system of thermal insulation products or light refractory products, intensity difference flaws.The advantages of their shortcomings is drift beads, so drift beads have more competitive advantages, used more widely.
4, excellent electrical insulation, non-conductive: choose after degaussing beads drift beads, is the performance of insulation materials, conductive.Insulation resistance are commonly by the rise of temperature, drift beads, on the other hand, increases with the increase of temperature resistance.This advantage is don't have other insulating materials.So, it can make is performance under the condition of high temperature insulation products.
5, particle size, specific surface area: drift beads natural formation of the particle size of 1

4. 不要在液体长时间沉淀后静止选择，在取样之前要对液体进行均匀搅拌，这样选出的才更具有参考价值。

在取样时一定要注意好注意事项，若是对有机类废水进行分析，那测试便要及时，避免搁置较长时间而引发性质发生变化，最终失去试验的意义。
