1. 洗煤廢水澄清劑陽(yáng)離子聚丙烯酰胺CPAM

博源凈水實(shí)驗(yàn)室對(duì)絮凝法處理洗煤廢水的實(shí)驗(yàn)研究也曾做過(guò)千余次實(shí)驗(yàn)，對(duì)洗煤行業(yè)有豐富的經(jīng)驗(yàn)。一般，洗煤廢水水量較大,色度大,污染性強(qiáng)。博源實(shí)驗(yàn)室分別對(duì)陰離子型、非離子型、陽(yáng)離子型三種有機(jī)高分子聚丙烯酰胺絮凝劑進(jìn)行配比實(shí)驗(yàn)，比較廢水處理效果,發(fā)現(xiàn)都不是非常理想。實(shí)驗(yàn)人員又將無(wú)機(jī)凝聚劑與這三種有機(jī)高分子絮凝劑復(fù)配使用,發(fā)現(xiàn)效果很好;有機(jī)高分子絮凝劑用量少,產(chǎn)生絮體時(shí)間短,礬花大而實(shí),沉降快。通過(guò)實(shí)驗(yàn)得出適宜的絮凝條件:100 mL廢水陰離子型聚丙烯酰胺的投加量0.001 g,硫酸鈉為0.06 g,pH為9.7,攪拌時(shí)間為20 min。在此條件下堿廠(chǎng)廢水COD去除率達(dá)到80.5%。廢水的色度去除率為92.9%。可以完全滿(mǎn)足洗煤廢水處理效果。作為洗煤廢水澄清劑使用的聚丙烯酰胺的減量投放，大大降低了運(yùn)營(yíng)成本。
