摘要
随着工业的快速发展,我国经济日新月异;伴随着工业的飞速发展,工业对环境的污染也日益严重;工业对环境污染的治理也成为我国改善民生居住环境的头等大事;在水资源日益紧张,工业废水的排放量日益增多的大趋势下,寻求经济有效的废水处理技术已成为重要的研究课题。以某铀多金属矿选矿废水为研究对象,经超滤、纳滤处理后,再以电渗析作为深度处理,废水中COD含量可从原始的450mg/L降至1.8mg/L;水中重金属含量可降至1mg/L以下,可达到纯净水水质标准。
With the rapid development of industry,the economy of our country change rapidly along with the rapid development of industry,the industrial pollution on the environment is increasingly serious;the governance of industrial pollution to the environment has become a top priority of our country to improve the livelihood of the living environment;the water resources become increasingly tense,the trend of emissions of industrial waste water is increasing.Seek economic and effective wastewater treatment technology has become an important research topic.In a uranium polymetallic ore beneficiation wastewater as the research object,by ultrafiltration,nanofiltration and electrodialysis to treatment,as the depth of processing,the content of COD in the wastewater from the original 450mg/L to 1.8 mg/L;the content of heavy metals in water can be reduced to below 1 mg/L,can reach the standard of pure water.
