مقارنه بين كفاءة الخلية الحيوية و الحماة المنشطة فى معالجة مياه الصرف الصحي

Abstract EN

The Al-Sint Forest and General Administration of Medical Services stations were chosen for the purpose of treating wastewater with a biofilm system and active protectors.

Asmall model of the treatment system with the active protections system was designed for the purpose of treatment and comparison between in the three systems.

Water Food quality environ ment lab from the wastewater at Al-Sint Forest Station before and after treatment in addition to the description of the treatment system followed.

The study showed that the results of the values of the quantities of oxygen absorbed dynamically BOD and the amount of oxygen absorbed chemically COD in the water entering and leaving As follows 520 - 2.6 , 1300 - 16 mg per liter, respectively The treatment efficiency was 99.5%, 98.77% respectively and in the General Administration Station for Medical Services BOD, COD in the inbound and outbound waters as follows 205-16 , 1280 - 112 mg per liter respectively and the treatment efficiency was 92.19% ,91.25% respectively and in a similar treatment system design Activated sludge after four o'clock is the best result in the first treatment stage BOD, COD in the in and out water as follows 80-20, 120-46 mg per liter respectively.

The treatment efficiency was 75%, 61.67% respectively and in the second stage of treatment BOD, COD in in and out water as follows: 100-65, 250-95 mg per liter, respectively and treatment efficiencies were 35% and 62% respectively.

The results obtained were compared with the standard criteria where it was found that the results of the tests some of which are within the permissible limit and some of them outside and the treatment technique using biofilms was the best then design and then activated sludge in the general management in medical services in terms of efficiency and treatment.
