The maintenance and replacement of the submersible flow propeller requires stopping production, cleaning the pool, and emptying the oxidation ditch of tens of thousands of tons of sewage sludge before it can be implemented. Stopping production may cause sewage overflow from the off-site pipe network, causing serious environmental pollution incidents and the risk of environmental protection penalties; after the installation is completed, a long period of process debugging is required, facing the severe situation of water quality not meeting the standards due to abnormal process operation, and there are also large economic losses caused by the suspension of production.
