一般重金屬?gòu)U水：主要為電鍍后的鍍件清洗水、簡(jiǎn)單酸洗廢水及酸性蝕刻廢水，主要含重金屬離子。<br>2 綜合廢水：主要為生產(chǎn)線上的多種酸、堿清洗水，含重金屬離子、SS及部分COD。<br>3 磨板廢水：主要來(lái)源于銅箔板表面處理刷磨階段的沖洗廢水、單純清洗廢水，主要含銅粉、火山灰等污染物。<br>4 銅氨絡(luò)合廢水：主要為堿性氨系蝕刻后清洗過(guò)程帶出液造成清洗水污染而產(chǎn)生銅氨廢水。<br>5 EDTA絡(luò)合廢水：來(lái)源于化學(xué)沉銅清洗工序。<br>6 有機(jī)廢水：主要來(lái)源于除油、脫脂工序的清洗水及網(wǎng)版清洗廢水。<br>7
