1. Check whether the inlet sewage pump and return pump of the air flotation machine are frozen every day when you go to work, including the lubrication and refueling of the water pump, the tightness of the packing, the sealing ratio of the bottom valve, and the filling of oil in the air compressor, etc.
2. Check whether the air filter valve of the air compressor is frozen to determine whether the air compressor is operating normally and whether there is any noise or heat.
3. Check whether the transmission part and scraper of the slag scraper have become hard and broken in the cold state, so as not to affect the use.
4. Pay attention to the coagulant mixing storage tank to avoid freezing, and conduct small sample tests frequently.
5. Check the valve pipelines of each equipment to avoid blockage in the valve pipelines, and place them in the "open" or "off" position as required.
6. The water must be drained when shutting down to avoid freezing and blocking.
