微氧生化-生物接触氧化法对癸二酸废水的处理特性研究

Gongye shui chuli
癸二酸废水属于典型难降解工业废水，废水处理难度大，且富含的高硫酸盐极易被还原为硫化氢释放，导致环境污染。采用微氧生化-生物接触氧化工艺处理癸二酸废水，考察其对难降解工业废水的处理特性。结果表明，当进水负荷逐渐趋于稳定，在进水COD 4 500~5 500 mg/L、挥发酚150~200 mg/L的情况下，经微氧生化-生物接触氧化工艺处理后，出水COD<400 mg/L，挥发酚<0.5 mg/L。系统中出水硫化物质量浓度均低于0.2 mg/L，表明系统内不易产生H2S。在微氧段构建及启动阶段 ...

氰化尾渣综合利用生产废水净化处理研究

, 2017
招远某矿业冶炼公司采用中国科学院过程工程研究所研发的高效富集选硫工艺进行氰化尾渣中硫、铁资源的富集再利用，生产出含硫量在48%以上的高硫精矿，高硫精矿进而生产硫酸以及副产含铁量在63%以上的铁精粉。通过该工艺技术实现了氰化尾渣的综合利用，减少了固废存放，降低了环境污染，提高了资源利用率。但整个生产过程中，高效富集选硫项目每天产生选矿废水400t，其铜、铅、锌和砷含量分别为2.1mg/l、1.8mg/l、8.3mg/l和10.5mg/l；采用二转二吸工艺生产硫酸项目产生废水130t，其铜、铅 ...

硫代硫酸盐法处理含铜硫化金精矿

, 1990
用L_(18)(6~1×3~6)正交表安排实验,考察了硫代硫酸盐溶液浸取硫化金精矿过程中,各因子对金浸取率及铜浸取率的影响。在最佳条件下,金浸取率可达96%。硫代硫酸盐浸取液可循环使用。实验还分别考察了浸取过程、置换过程,溶液静置过程中硫代硫酸盐的损失。提出了如何控制条件 ...
