WATER PURIFICATION INTAKE FACILITY Russian patent published in 2018 - IPC E02B8/02 

FIELD: hydraulic equipment.

SUBSTANCE: invention relates to hydraulic engineering, namely to facilities for complex water treatment from drawn and part of suspended sediment during water intake into canals, pipelines and antechambers of pumping stations. Water intake treatment plant includes intake sludge pre-chamber 1, clean water intake chamber 2 and supply conduit 15. Settling pre-chamber 1 includes additional sulfur-retaining grid 10 fixed above it, inclined guide wall 12 installed inside directly under the additional sulfur-retaining grid, vertical partition 3 separating the body of the pre-chamber to clean water intake chamber 2 and settling pre-chamber 1. Outlet window 6 formed in partition 3 is communicated via branch pipe 7 with dirt-retaining grid 8 and vertical L-shaped rack 16 directed downward in settling pre-chamber 1. Waste water collector 11 is placed in the bottom of settling pre-chamber 1. Window 6 with branch pipe 7 is made in the middle part of partition 3. Clean water intake chamber 2 has piping manifold 13 to the user. Inclined guide wall 12 is waterproof and covers clean water intake chamber 2 from above. When the plant is in operation, a part of the water with large deposits and debris slides down inclined additional grid 10 into disposal gutter 14, where they are transported down the slope of the gutter.

EFFECT: efficiency of continuous water purification from bottom and suspended sediments, as well as debris beyond the boundaries of the plant is improved, and it becomes possible to regulate the hydraulic structure of the flow in the settling pre-chamber.
