Construction Work – Reconstruction Of The Sewage Treatment Plant In Nysa. Iii.1. Purpose Of The Planned Investment 1. The Investment In Question Involves The Reconstruction Of The Existing Sewage Treatment Plant In Nysa. The Treatment Plant Is Supplied With Municipal Sewage (Mixed Domestic Sewage, Industrial Sewage And Rainwater) From The Collective Sewage System Of The Nysa Agglomeration, Including The Communes Of Nysa, Otmuchów And Głuchołazy, As Well As Industrial And Domestic Sewage Transported By Sewage Trucks. Treated Sewage Is Discharged Into The Nysa Kłodzka River At Km 59+810. The Following Technological Facilities Are Located On The Premises: • Main Sewage Pumping Station, • Building Of Mechanical Grates, • Horizontal 3-Chamber Sand Trap, • Kpv-X Measuring Trough With A Venturi Nozzle, • Sand Drying Plots, • Radial Primary Settling Tanks, • Aeration Chambers, • Radial Secondary Settling Tanks, • Sewage And Sludge Recirculation Pumping Station, • Pumping Station For Raw And Excess Sludge And Own Sludge, • Thickening Of Raw And Excess Sludge, • Wkf Engine Room With A Boiler Room, • Two Closed Fermentation Chambers, • Digested Sludge Thickener With A Pumping Station, • Dewatered Sludge Landfill, • Fuel And Slag Landfill, • Sludge Dewatering Station, • Gas Tank, • Gas Flare, • Own Industrial Water Hydrophore Plant, • Main Building Of The Facilities, • Pipe Culvert - Covering The Bielawa Canal, • High-Voltage Switchboard With A Transformer Station For The Mechanical Part, • Open Earth Fermentation Chambers, • Blower Station, • Wkf - Old Sewage Treatment Plant, • Catchment Area For Supplied Sewage. The Treatment Plant Has Separate Technological Lines: 1) Sewage Line Consisting Of: A) Mechanical Treatment Part, B) Biological Treatment Part, C) Chemical Stage Of Treatment, I.E. Installation For Dosing Reagents For Sludge Precipitation 2) Sewage Sludge And Fatty Waste Processing Line Consisting Of: A) Three Sand Leachate Plots B) Raw Sludge Pumping Station C) Tanks Mixed Sludge Retention/Thickeners With Second-Stage Raw Sludge Centrifugal Pumps, D) Closed Sludge Digestion Chambers, E) Technical Building (Engine Room) For Sludge Management With A Sludge Circulation And Heating System, F) Two Open Digestion Chambers (Earth Tanks), G) Centrifuge Station For Mechanical Sludge Dewatering, H) Open Dewatered Sludge Storage Facility 3) Biogas Cleaning, Storage And Utilization Line Consists Of: A) Biogas Intake In Wkf Chambers B) Two Biogas Desulphurization Scrubbers On Bog Ore, A Gas Measurement And Pumping Station C) A Biogas Tank With A Capacity Of V = 2000M3 D) A Biogas Flare E) A Cogeneration/Generator Unit Accompanying Facilities: • Social And Technical Building, • Hv Switchboard Building With A Transformer Station, • Water Pumping Station Technological Plant, • Catchment Area For Transported Sewage, • Oil And Gas Boiler Room With A Power Generator. The Investment Is Planned To Include: 1) Liquidation Of Existing, Technically Worn Out And Technically Obsolete Facilities, I.E.
