What should be paid attention to in rural domestic sewage treatment equipment in cold weather?

With the coming of autumn and winter, rural domestic sewage treatment equipment will encounter a big problem-low temperature test, especially in the northern region. It should be noted that:

Before the arrival of winter, the maintenance personnel of rural domestic sewage treatment equipment need to carry out detailed maintenance and overhaul of the equipment. Sewage treatment equipment in the north is generally placed under the frozen soil layer, and of course many of them are built on the ground.

For the equipment built on the ground, in order to prevent freezing and cracking at low temperature or freezing, the hardware equipment needs to be equipped with thermal insulation materials in winter to protect the normal operation of water pipes, motors, valves and other equipment. It would be great if there were special heating equipment. The sewage treatment equipment built underground, because the temperature is relatively constant, only needs to maintain hardware facilities such as pipelines and valves exposed on the ground.

Secondly, it should be noted that with the decrease of temperature, the activity of microorganisms also decreases. We need to adjust each link of water treatment according to the treatment process to ensure the treatment effect. For example, the aeration time can be appropriately extended to increase the sludge concentration.

Finally, in order to ensure the normal operation of sewage treatment equipment throughout the winter, maintenance personnel need to strengthen the inspection of key parts and pay attention to anti-skid during inspection to prevent safety accidents.
