摘要：

在生产性试验条件下,考察了橡胶膜片曝气器与钟罩式刚玉曝气器在UNITANK工艺中的实际应用情况。结果表明,与橡胶膜片曝气器相比,钟罩式刚玉曝气器具有足够的机械强度,寿命较长,能保证曝气系统始终正常稳定运行。运行中在曝气器数量相等及相同供气量条件下,采用橡胶膜片曝气器的UNITANK边池的DO最高为5.4mg/L,采用钟罩式刚玉曝气器的DO最高为3.2mg/L,按目前的进水水质及出水标准,刚玉曝气器能够满足当前工艺运行要求。

Abstract:

Under the condition of applying scale test of UNITANK process,rubber film aerator and campanulate corundum aerator have been investigated.The results show that comparing with the former,the latter is characterized by higher machine intensity and longer life-span,and can ensure the stable operation normally.When the quantity of aerator is equal and the air supplied is the same,the highest DO concentration in the side tank equipped with rubber film aerator is 5.4 mg/L,while that in side tank equipped with campanulate corundum aerator is 3.2 mg/L.According to the quality of inlet water and the discharge water standard,corundum aerator can meet the request of current operation.

Key words: aerator, rubber film aerator, campanulate corundum aerator
