铁矿浮选厂尾矿废水对家鱼的毒性及排放指标的探讨

, 1959
<正> 一、前言在工业废水排入水体时,除了要考虑卫生标准外,还必须注意废水对鱼类的毒害和因废水排入,以致水体原来的物理、化学条件的破坏,而影响到水生生物的生长和繁殖等问题。本文的目的是为了配合×××浮选厂的排水设计 ...

水解酸化+两级SBR工艺处理天然气净化废水与回用

, 2010
天然气净化废水水质水量波动大,且含有大量难降解物质,一直难以稳定达标。本工程采用水解酸化+两级SBR法工艺处理天然气净化废水,在进水均值ρ(COD)=943 mg/L、(ρBOD)=268 mg/L、ρ(NH3-N)=30.5 mg/L时,出水均值ρ(COD)=37.4 mg/L、ρ(BOD)=4.7 mg/L、ρ(NH3-N)=1.9 mg/L,完全达到GB8978-1996《污水综合排放标准》一级标准,工程运行稳定。出水回用于循环冷却、绿化、冲厕、道路冲洗等,回用率达到100 ...

石化废水处理厂特征污染物变化及水质安全研究

Gongye shui chuli
石化废水污染控制与水质安全是水环境领域污染防治的重要课题，但是目前关于石化废水处理工艺中特征污染物的组成变化及水质安全性尚未深入探讨。研究了某石化废水处理厂在废水处理过程中废水特征污染物的浓度变化和毒性削减效应。结果表明，预处理阶段COD和石油类去除率分别为36.38%和95.16%，出水生物毒性有效降低。生化处理单元COD和氨氮去除率分别达到63.19%和43.21%，废水中酚类、酯类、胺类等有机物含量显著降低。石化废水经过深度处理后，COD、BOD5、石油类、氨氮、总氮分别为（32.54±4.93）、
