A submerged ultrafiltration membrane tank with online recovery of self-flowing water

Abstract

The invention discloses an artesian water on-line recovery immersed ultrafiltration membrane pool, and relates to the technical field of water feeding treatment process. A front-end water pool is connected with a main water distribution channel through a first pipeline; a water inlet adjustment valve is arranged on the first pipeline; a main water distribution channel overflow pipe is arranged above the main water distribution channel; a main water distribution channel emptying pipe is arranged at the bottom of the main water distribution water channel; an opening in one end of a water inlet siphon pipe is formed in the main water distribution channel; an opening in the other end of the water inlet siphon pipe is formed in a membrane pool water distribution trough; the upper side of the water inlet siphon pipe is respectively connected with a water inlet vacuum pumping valve and a water inlet siphon breakage valve; the water inlet vacuum pumping valve is connected with a first vacuum pump; the membrane pool water distribution trough is communicated with the membrane pool through a membrane pool water distribution hole; an immersed ultrafiltration membrane box is arranged below a normal water level of a membrane pool body; and a membrane box water collection pipe is connected with a membrane box water producing pipe. The artesian water on-line recovery immersed ultrafiltration membrane pool is simple in structure and convenient to run and maintain; the stability of ultrafiltration membrane water production is improved; and ultrafiltration water supply safety is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of water supply treatment technology, in particular to a submerged ultrafiltration membrane pool of self-flowing effluent on-line recovery type. Background technique: [0002] At present, the submerged ultrafiltration membrane water supply treatment system of domestic waterworks mostly adopts the off-line recovery cleaning method. This method separates the recovery cleaning of the ultrafiltration membrane from normal production, so as to prevent the impact of chemical cleaning agents on production and eliminate unsafe water supply factors. . However, this offline method requires a lot of dismantling, crane lifting, and installation workload, which inevitably brings many unsafe factors, such as crane instability, heavy object falling damage, collision, extrusion, rolling damage, electric shock, etc. Invention content: [0003] The purpose of the present invention is to provide a self-flowing water online...
