The experiment investigated the relationship between the characteristic curve of producing of NO_2—N of mixed liquid with phenol in aeration tank, with reducing condition and vibrating cultures, and the removal ratio of phenol and change of state of activated sludge. The results represented that there was a good relationship between the characteristic curve of producing of NO_2—N measured in reducing condition and influent flow rate, PH, DO, SVI and removal ratio of BOD and COD. The change of state of activated...

The experiment investigated the relationship between the characteristic curve of producing of NO_2—N of mixed liquid with phenol in aeration tank, with reducing condition and vibrating cultures, and the removal ratio of phenol and change of state of activated sludge. The results represented that there was a good relationship between the characteristic curve of producing of NO_2—N measured in reducing condition and influent flow rate, PH, DO, SVI and removal ratio of BOD and COD. The change of state of activated sludge and removal ratio of waste can be determined by the characteristic curve of producing of NO_2—N measured in reducing condition.

本实验系统地考察了含酚废水曝气池混合液在还原条件下振荡培养时所测得的亚硝酸氮的生成特性曲线与废水净化程度,活性污泥性状的变化关系。试验表明,在还原条件下测得的亚硝酸氮的生成特性曲线与进水负荷、PH值、DO、SVI及COD和BOD去除率有很好的对应关系。因此,通过亚硝酸氮生成特性曲线的形状,能早期判断曝气池活性污泥的性状变化和废水净化程度。

In this paper, we study microbial population in the activated sludge. It shows that bacterium is main, except a few mold, yeast etc.in the system.It is a Co-ecosystem.It can reduce PH value and decompose dyestaff of all kinds. The quantities of bacteria are different in different samples. The microflora is different, too. And bacteria in the aerator for decoloring is tested.

本文通过对利用活性污泥法处理印染废水的曝气池中微生物类群的初步研究表明,该系统为以细菌为主,含有少量霉菌、酵母等的复合生态系统。它具有降低pH值,降解各种色源物质等有机废物浓度的能力。在不同的水质中含菌量不同,微生物区系差别更大。并对曝气池中的细菌菌株初步进行了脱色能力的探讨。

Sometimes the ability of oxygen transfer in the aeration tank loses unexpectedly since the surface aerator falls into splashing state.The causes accounting for and some measuresto prevent this occurence are described in the paper.

本文分析了上海石化总厂水质净化厂废水曝气池中曝气机叶轮在运转中突然产生甩水异常,乃至不起浪花、不起充氧作用的原因,并介绍了排除方法。
