摘要
通过改变进水有机负荷 ,对两级串联浸没式生物膜污水处理装置的技术性能进行了研究 .其内容涉及到 :各级反应器的有机物去除分担率、过滤器的作用、单双级生物反应器比较等问题 .结果表明 :第一、二级反应器分别承担了溶解性有机物去除负荷的 76%和 2 4%.;砂滤系统对前一级出水COD的去除率高达 42 %;在相同有机负荷下 ,相对单级反应器 ,双级反应器不但有机物去除率高 。
The two stage immerged biological film wastewater treatment reactor was studied in different organic loads. The organic removal efficiency of each stage, filter capability and technical contrast between one stage reactor and two stages reactor were discussed. The results showed that the distribution ratio of organic removal were 76% and 24% in first and second stage reactors respectively, COD removal efficiency was 42% in sand filter unit, and the two stage reactor was more effective and reliable than one stage reactor in the same organic loads.
