1、问:有的A/O工艺中,A段为厌氧段,为什么还要空气管曝气呢?

2、问:我做的100吨中试项目,近期氨氮去除效果不好,目前观察的情况看:供氧应该还可以、碱度充足、生物活性尚可且无明显毒性、污水闷曝还是不行,是否可以认为负荷不成问题?有机氮的氨化和硝化,是不是同时进行,其中氨化要稍微领先于硝化?有没有其它影响硝化的因素?

3、问:我现调试一个屠宰废水,工艺为:化粪池(HRT>2d)-调节池-水解池(HRT=5)-接触氧化池(HRT=6)-二沉池,由于前化粪池出水COD在700,而且接触氧化时间比较短,故将水触池改为曝气池,但所加的一台潜水曝气机效果有限DO一般在0.5以下,原曝气池DO正常.两池的SV都可达到20-30,现在进水量为设计水量的70%,出水水质仍然很差,SS较多,原曝气池有一定的泡沫,且比较稠,是否是因为污泥老化的原因造成的?

6、问:近段时间本单位的污泥脱水机(带式压滤)滤布常会跑偏,是什么原因?

7、问:我们的好氧池为生物接触氧化池,目的是将氨氮从30降至10以下,实际现在加显色剂后和空白差不多。加碳酸钠调节碱度,从后面沉淀池回流污泥,由于回流不好控制,所以有时是泥有时是水。以前发现没污泥回流时整个好氧池的pH值就随水流方向急剧下降,但有污泥回流时就不会了,能保证出水pH值在6.5-7之间。但近几天发现整个好氧池pH值偏低,前端仅6.9,出水5.8左右(进水所有指标和碳酸钠量均未改变,氨氮浓度依然测不出),即使相对以前改善污泥回流状态也是这样请问这是什么原因造成的?另外我们好氧池后面的沉淀池是竖流沉淀池(148m3,水量30m3/h),下面有四个小泥斗,在现有状况下应采取什么措施改善好氧池回流污泥状态?
