After long-term operation of the aerator, calcium and iron deposits in the water are easy to deposit on the aeration diaphragm. The deposits will block the holes of the aeration plate and affect the aeration effect, which greatly increases the oxygenation capacity and stirring performance. reduce. Jin Yong Environmental Protection recommends regular cleaning of the aerator, and the cleaning cycle should be determined according to the operating conditions. The following methods can be used for cleaning:
Drain the aeration tank, clean with water and brush or high pressure;
Drain the aeration tank, remove the aerator, and clean them one by one;
Remove the aeration group from the aeration tank and clean the aerators one by one;
Clean with automatic cleaning device during operation (formic acid);
Studies have shown that using formic acid pickling is a good way to clean aeration pans. The entire formic acid pickling process does not affect the normal operation of sewage treatment work, and is of great significance to the maintenance and extension of the service life of the aerator. Moreover, this method is more convenient and economical than other measures.
