Why is the aerobic tank sludge less and less

The reasons for the decreasing amount of aerobic sludge are mainly as follows:

1. Excessive aeration and excessive control of dissolved oxygen value

The influence of excessive aeration on the increase of activated sludge concentration is mainly manifested in that the free bacteria generated in the process of activated sludge upgrading are easy to be oxidized by excessive aeration, which makes the activated sludge concentration unable to further increase. To this end, maintaining a reasonable aeration rate requires frequent confirmation by the operator, and the confirmed aeration effect is the dissolved oxygen value in the entire biochemical tank range.

2. Insufficient dosage of nutrients

The addition of nutrients is very important in activated sludge culture and the normal operation stage. As a necessary component of the cell, nutrients are absolutely indispensable, otherwise even the formation of basic bacterial micelles will be inhibited.

3. The concentration of substances entering the bottom is too low

The energy required for the growth and reproduction of activated sludge comes from the organic matter in sewage and wastewater, and the organic content in sewage and wastewater determines how large the total activated sludge community can be supported.

4 The incoming water contains excessive amounts of toxic or inhibitory substances

The inflow of refractory organic matter or toxic substances has a great influence on the normal reproduction of activated sludge.
