Cultivation steps:

Close the water inlet and outlet valves of the biochemical pool, start the stirring device when there is stirring in the anoxic pool, and pre-aerate the aeration equipment of the aerobic pool 2 hours in advance to make the dissolved oxygen in the water reach 2-4mg/L, and control the anaerobic (anoxic) dissolved oxygen below 0.5mg/L; It is better to control the PH of biochemical pool at 6-9 and aerobic pool at 7-8.5. It is suggested that the temperature of biochemical pool should be controlled between 10-35.

The solid powder bacteria can only be added after being dissolved in the sewage of the biochemical pool, and the dissolution ratio of bacteria and water is 1: 10. Dissolved bacteria are added to aerobic and anoxic tanks that have been stirred and aerated before.

After the water is closed, the organic matter in the water is limited for two days, and a large amount of organic matter needs to be consumed in the process of bacterial reproduction. Nutrient sources such as glucose, urea and dihydrogen phosphate are artificially added.

Continuous aeration for 24 hours, so that microorganisms are activated, attached to the bacterial bed and propagated, reaching an active state.

It is suggested that the influent should be adjusted in stages to reduce the influence on cultured bacteria. The water inflow on the first day of operation is 65438+ 0.5 of the normal water inflow, the second day is 2/5 of the normal water inflow, and the third day is 3/5 of the normal water inflow. On the fourth day, it is 4/5 of the normal water inflow, and on the fifth day, it can enter and exit the water normally.
