The Subject Of The Order Includes The Following Elements: Overflow Chamber - To Be Reconstructed With A Measuring Chamber. Raw Sewage Pumping Station - New Facility. Supplied Sewage Catchment Station With A 20M3 Underground Tank - New Facility. Building Technological And Social – New Facility. (Without Equipment, Limited Installations, Small Heat Pump).Sand Screener, Bioreactor - Construction Of A New Reactor With Secondary Settling Tanks And A Sludge Stabilization Chamber, Blower Station - New Facility. (Reactor - Steel Structure Facility, Without Casing) + Pix + Purified Sewage Measurement Chamber + Commissioning. Sludge Dewatering Station With Sludge Hygienization Installation - New Facility. Dewatered Sludge Storage Building - New Facility. (Reduced By Half 17X10 M). External Infrastructure Of The Area. Photovoltaic Installation. Reconstruction Of The Existing Fence. External Energy Networks + Control + Scada + Measurements. Roads And Maneuvering Areas (Reduced Scope Of Approx. 700 M2) + Greenery. Area Lighting With Monitoring. Demolition Of The Social Building. All Planned Works Will Be Carried Out Within The Boundaries Of The Existing Sewage Treatment Plant - Plot No. 202/1, District Płonica. Quantitative Balance Of Sewage. Qaverage = 465.00 M3 /D – Average Daily Amount Of Sewage; Qmaxh = 36.00 M3 /H – Max. Hourly Amount Of Sewage; Qmaxd = 864.00 M3 /D – Max. Daily Amount Of Sewage; Qmaxr = 516,370.00 M3 /Y – Max. Annual Amount Of Sewage; Quality Balance Of Sewage. The Quality Balance Of Raw Sewage Flowing To The Sewage Treatment Plant Was Developed On The Basis Of Literature Data (According To The Imhoff Guide) And Tests Of Raw Sewage Supplied To The Treatment Plant. The Following Was Assumed: S Bzt5 = 300.00 Mg O2/Dm3 - Organic Pollutants; Schzt = 600.00 Mg O2/Dm3 – Organic Pollutants; Shaw. Og. = 315.00 Mg/Dm3 - Total Suspended Solids. Sn = 110.00 Mg/Dm3 - Total Nitrogen. Sp = 18.00 Mg/Dm3 - Total Phosphorus. Balance Of Pollutant Loads. The Balance Of Pollutant Loads Contained In Sewage Supplied To The Sewage Treatment Plant Was Determined Based On Knowledge Of The Sewage Balance And Pollutant Concentrations. The Balance Of Pollutant Loads Was Determined From The Relationship: The Calculation Results Are Presented In The Table: Summary Of The Balance Of Pollutant Loads In Sewage Flowing Into The Treatment Plant.
