摘要:
本研究采用A/O工艺生物处理方法和混凝沉淀法处理选矿药剂生产废水，依据厌氧–好氧去除有机物机理和混凝沉淀的絮凝效果，通过控制工艺运行参数，最终得到试验的研究结论。结果表明，该组合方法可有效的去除污水中的有机污染物、浊度和氨氮，去除率分别达到97%、97.2%、98.7%。出水水质完全满足国家《污水综合排放标准》(GB8978-2002二级标准)。根据实验运行情况，提出A/O工艺和混凝沉淀的合理布置及运行参数，用于现场工艺改进及设计提供参考[1]。
In this study, the A/O biological treatment method and the coagulation sedimentation treatment are adopted for wastewater from the production of mineral processing reagents, according to anaerobic-aerobic dislodge organic mechanism mixed flocculation sedimentation,s by controlling technological operational parameters, getting the final result of test research. The results show that the combined method can effectively remove the organic pollutants, turbidity and ammonia nitrogen, and the removal rate reached 97%, 97.2%, 98.7%. The production water qualities completely reach the national integrated wastewater discharge standard (GB8978-2002 secondary standard). According to the condition of the test, the operation parameters and the reasonable layout of A/O technology and coagulation are introduced. Then, it can be used as reference for the design and technical process improvements [1].
