What should we pay attention to in rural domestic sewage treatment equipment in cold weather?

As autumn and winter come, rural domestic sewage treatment equipment will encounter a big problem - low temperature test, especially in the northern region. At this time, you need to pay attention:

Before winter comes, maintenance personnel of rural domestic sewage treatment equipment need to carry out detailed maintenance and inspection of the equipment. Generally speaking, sewage treatment equipment in the north is usually placed under the permafrost layer, and of course there are also some built on the ground.

For equipment built on the ground, in order to prevent low-temperature freezing or icing, the hardware equipment must be equipped with insulation materials in winter to protect the normal operation of water pipes, motors, valves and other equipment. If It would be great to have dedicated heating equipment. Since the temperature of sewage treatment equipment built underground is relatively constant, only the pipes, valves and other hardware facilities exposed on the ground need to be maintained.

Secondly, it should be noted that as the temperature drops, the activity of microorganisms also decreases. We need to adjust all aspects of water treatment according to the treatment process to ensure the treatment effect. For example, the aeration time can be appropriately extended, the sludge concentration can be increased, etc.

Finally, in order to ensure that the sewage treatment equipment can operate normally throughout the winter, maintenance personnel need to strengthen inspections of key parts, and pay attention to anti-skid during inspections to prevent safety accidents.
