A water treatment station heliofilter-bioplateau consists of bioplateau, comprising the body, filled with granular loading, in which higher aquatic plants are planted, pipelines for the water supply to the purification with drainage system of its distribution in the zone of root system of the higher aquatic plants, assembly drainage systems, fixed in the lower part of the body and connected to the pipeline for the outlet of the purified water. Additionally it is equipped with the upper and lower circulation drainages, placed in the granular loading bioplateau body between distribution drainage and assembly drainage system, besides the upper circulation drainage is connected by the pipeline with collecting tank, equipped with circulation aggregate of water supply line to the separate self rinse filtering block, in which complex filtering loading from zeolite tuff and/or brucite granular material is placed, which is separated by the perforated baffle from the loading of floating polystyrene foam granules, in the lower zone of which the system for gathering of filtrate is placed, which is by the corresponding pipeline is connected with the lower circulation drainage of bioplateau, and siphon flat-topped pipeline of the rinse water of a separate self rinse filtering block is established in the hydraulic lock, which is hydraulically connected with the clarifier and which is additionally equipped with the system for dosing rate of reagents and biodestructors-enzymes and line for gathering and supply of the clarified water into the pipeline for water supply to the purification in bioplateau. |
