摘要
重革废水经采用分路处理的方法回收有用资源 ,然后并路进入充气上流式铁屑固定床除硫与进一步降解有机物 ,再经混凝处理 ,可使 SS、COD、S2 -及色度的去除率都能保证在 96 %以上 ,出水达到 GB4 2 87-92制革行业废水的一级排放标准。该技术具有投资省 ,操作方便 ,运行效果稳定 ,高效。
The vegetable tanning waste water is disposed through the divided route and recovery resource, S 2- removed and organic pollutants degraded by iron-bed with up-flowing water and coagulating way.The removal ratios of SS,COD,S 2- and colour are above 96%,and the standard of allowed outflow water has reached the first grade standard GB4287-92 of tanning industry. Low invest, work convenience, stable and economical work effect are characters of this technic.
