【摘要】 废水生物处理的可行性和废水的组成情况及微生物的生活条件,有着密切的联系.论文对经物化处理后的蔗渣亚铵法制浆混合废水的可生物处理性进行了研究.针对生物需氧量/化学需氧量(BOD5/CODcr)比值法的不足,采用呼吸速率法评价废水的可生物处理性,实验室工作和实际运行均表明,该废水具有较好的可生物处理性,相对于BOD5/CODcr比值法而言,呼吸速率法所用的时间短,能较快得出接近实际的评价.更多还原

【Abstract】 There is a close relation between biotreatment feasibility of effluent and composing of effluent and living condition of microorganism. In this paper, it was studied that the biotreatment feasibility of bagasse ammonium sulfite pulping effluent which was treated by flocculation and flotation. Due to the shortage of BOD5/CODcr method, breathing rate method was introduced in this test, the results of laboratory and practically operation showed that the effluent have a good biotreatment feasibility. In contrasted with BOD5/CODcr, the results of breathing rate method is close to the practicality.更多还原
