INFLUENCE OF INFLOW SEWAGE CHARACTERISTICS ON THE PERFORMANCE OF TAHTA WASTE STABILIZATION PONDS IN COMPARISON WITH THE DESIGN ONES

摘要: TAHTA waste water treatment plant is a (WSPs) constructed for the domestic of city which located at latitude 26˚42' N and longitude 31˚41'E it about 91.00 m above sea level. The performance along three years study period estimated in form comparison between results total system or its components with allowable values studied parameters, relation input output these parameters as efficiency. final effluent characteristics are compared designed ones those recommended by Egyptian Code Practice (ECP) Food Agriculture Organization (FAO) re-use treated this type treatment. existing operation considered unrealistic because deviation flow from ones. ponds were full capacity rates, influent BOD, etc. So, research aiming to: 1) Evaluate under conditions. 2) Examine whether quality range standards set 3) Identify problems associates plant. 4) Suggest ways to improve performed experimentally where daily sampling laboratory analysis carried out according standard specifications. revealed that Plant working satisfactory fulfil requirement use irrigating forest trees one construction purposes. As did not meet design such low rate coming BOD5 loadings treating some due sludge accumulation anaerobic ponds, incoming sewage 2016 higher than capacity. So; a) Sludge accumulated should be removed when depth reaches 1.00 recommendations half volume [13]. b) Flow distribution checked uniform otherwise short circuiting problem faced. c) Inflow must otherwise, receive more inflow surround area modifications may used According recommendation, wastewater acceptable re-used irrigation wooden tree forests.
