某铅锌冶炼企业废水处理工艺及应用

摘要

根据铅锌冶炼企业废水产生特点，采用生物制剂去除重金属与双膜法脱盐相结合的处理工艺，并实现出水回用；与传统的石灰法等工艺相比，生物制剂处理后废水中铅、砷、镉等重金属离子去除率明显提高，且含重金属污泥量大大减少。%Based on the characteristics of wastewater generated from a lead-zinc smleter,the paper presented the treatment process adopting biological agent in combination with desalination through ultrafiltration and reverse osmosis to recycle wastewater;the paper pointed out that the wastewater quality was improved after the treatment with biological agent in removing heavy metals such as lead,arsenic,cadmium,etc.and in decreasing the sludge containing heavy metals compared to conventional lime based process.
