Does the biofilm process not require sludge removal? What on earth is a hydrolysis acidification tank?
Thread Content
I’m not trained in sewage treatment. Our company has installed a new set of sewage treatment equipment that uses the biofilm process. The designer has sent someone to assist with the commissioning of this equipment. Today I discussed the issue of excess sludge with him; he said that their design does not require the removal of dead or aged sludge, as all such sludge is returned to the hydrolysis-acidification tank before anaerobic treatment, where it can be completely decomposed. I would like to ask the experts whether this is indeed the case. Then I saw their hydrolysis and acidification tank, which is just a pool with nothing else in it – is it really as amazing as they claim? ?
I’m not here to answer questions; I’m here to ask them. Could you tell me what is the daily treatment capacity of your company’s biofilm method for wastewater treatment? What’s the approximate quote? We also plan to go
It is not a problem for the excess sludge from aerobic sludge to be fed into the hydrolysis-acidification process; originally, there is already relatively little excess sludge from contact oxidation. However, it is necessary to monitor the operation of the hydrolysis-acidification process. If the addition of aerobic sludge causes an increase in DO levels, it is important to control the amount of aerobic sludge added. Moreover, since the amount of excess sludge from hydrolysis-acidification is small, sludge removal is still required even in such cases. Especially when aerobic sludge is also added, it is essential to control the discharge of excess sludge from hydrolysis-acidification.
At least I haven’t seen anyone do it that way. Someone once said something similar: their aerobic tanks never discharge sludge, and all the aerobic sludge produced is sent to the anaerobic tower ahead. The anaerobic tank can treat both water and sludge, and the water quality can meet the standards. In fact, operational tests have shown that his project has very poor anaerobic performance.
