Abstract
The invention discloses an aerating system for a papermaking wastewater treatment tank. The aerating system comprises an aerating pipeline, a water spraying pipeline and a plurality of bearing supports, wherein the bearing supports are arranged in the wastewater treatment tank, and the top ends of the bearing supports are higher than the liquid level of the wastewater treatment tank; the aerating pipeline comprises a mother air pipe and a branch air pipe; the water spraying pipeline comprises a mother water pipe and a branch water pipe; the mother air pipe and the mother water pipe are fixed at the top ends of the bearing supports, one end of the branch air pipe is connected to the mother air pipe through a valve, the other end of the branch air pipe is provided with an aerating head and extends downwardly into wastewater in the wastewater treatment tank, one end of the branch water pipe is connected to the mother water pipe through a valve, and the other end of the branch water pipe extends downwardly into the wastewater in the wastewater treatment tank and connected with the aerating head. The aerating system has the advantages that the system is low in blocking probability and convenient in blocking clearing, and blocking clearing of the aerating head can be performed without emptying the wastewater treatment tank.
Description
technical field [0001] The invention relates to the field of papermaking wastewater treatment, in particular to an aeration system for a papermaking wastewater treatment pool. Background technique [0002] Underwater jet aeration is currently a popular aerobic aeration method in sewage treatment plants in the paper industry. Generally, all main pipeline jet devices are installed and fixed at the bottom of the aeration tank at one time. However, due to the high calcium content in papermaking wastewater, The ejector channel is often blocked due to fouling and needs to be cleaned frequently. Whenever it is necessary to clear the blockage, the pool body must be emptied, and it must be thoroughly cleaned at the bottom of the pool. The concentration is high, the workload is heavy, the time is tight, and a lot of manpower and material resources are consumed. Moreover, it takes a long time for emptying and cleaning (at least 1 week or more, depending on the specific situation), dur...
