STORMWATER AND COMBINED SEWER STORAGE TANK VACUUM FLUSHING SYSTEM

摘要

The present invention relates to a storage tank washing apparatus for convenient and safe maintenance of the storage tank by facilitating the treatment of sediment deposited in the rainwater and integrated sewage storage tank (hereinafter referred to as the storage tank). The present invention forms a washing tank in a storage tank storing rainwater from rainwater (sewage) pipes, and forms a siphon flow path between the washing tank and the storage tank, and applies a vacuum to the washing tank, through the siphon flow path. By sucking and storing the storage water in the storage tank and releasing the vacuum, the washing water in the washing tank is suddenly leaked through the siphon flow path (dam breaking effect) to wash away the sediment deposited on the bottom of the storage tank. Since the washing process is automatic, the operation of the storage tank is convenient, and since the washing machine does not have any mechanical parts in contact with the storage water, the maintenance cost is reduced, and the washing water is pushed out like a wave through the siphon flow. By flushing the bottom, the sediment is effectively treated.;Storm pipe, sewer pipe, reservoir, sediment, water washing, siphon
