双功能膜-序批式生物反应器中膜的污染与清洗

Gongye shui chuli, 2010
采用双功能膜-序批式生物反应器处理实际洗浴污水,考察了膜污染特征及清洗情况。通过实际清洗及对清洗前后膜组件表观观测,发现双功能膜-序批式生物反应器中的膜污染大多是可逆的;不同清洗顺序、化学药剂与膜接触时间不同对膜过滤性能恢复的效果不同;物理清洗可以有效去除膜表面淤积的污泥及颗粒沉积物,使膜的过滤性能恢复至新膜的60%～80%;用0.5%的NaClO和0.5%的H2SO4溶液进一步浸洗膜组件,可使膜过滤性能得到全面恢复,膜通量恢复到接近初始状态。

某电路板企业生产废水处理与回用工程实例及分析

Gongye shui chuli
某电路板企业的生产废水来源于晒版冲洗废水、显影及显影后清洗废水、脱墨后清洗废水、蚀刻清洗废水、前处理清洗废水、中处理清洗废水、有机可焊性保护层（OSP）抗氧化清洗废水等。将生产废水划分为高浓度有机废水、蚀刻清洗废水及一般清洗废水进行单独预处理后，再汇合进行生化处理及深度处理。结果表明，排放废水经处理后，COD≤95 mg/L、BOD5≤22.4 mg/L、NH3-N≤11.3 mg/L、SS≤78 mg/L，稳定达到《电子工艺水污染物排放标准》（GB 39731—2020）间接排放限值和广东省 ...
