Abstract

Atık stabilizasyon havuzu (ASH), evsel atık su ve diğer kanalizasyon türlerinin uzun süre

bekletildiği, içinde bulunan organik materyallerin ışığa, ısınmaya, alg ve mikroorganizmaların

büyümesine ortam hazırlayarak çökelmesine, parçalanmasına ve stabilize edilmesini sağlayan bir

kuyudur. Bu çalışmada; İran’ın Ahvaz bölgesinde bulunan bir mezbahane toplanan ve arıtma tesisinde

arıtılmış atık sulardan numune alınarak ASH ile atık suyun arıtımındaki verimin saptanması ve sulama

amaçlı kullanılabilmesi için İran Çevre Koruma Örgütü tarafından belirlenen standartlarla ilgili ölçülen

parametrelerin karşılaştırılması yapılmıştır. Çalışma sonucunda, arıtılmış atık suyun Türbiditesi, BOİ5,

pH, KOİ, TÇKM ve TAKM değerleri sırasıyla > 1000 NTU, 912 mg/L, 8.78, 1520 mg/L, 1052 mg/L ve 2180

mg/L olarak elde edilmiştir. Bu değerlerin İran Çevre Koruma Örgütü tarafından belirlenen standart

değerlerle karşılaştırılması sonucunda anlamlı bir farklılık gözlemlenmektedir. Bulgular sonucunda

çalışmakta olan atık su arıtma tesisinin verimlilik ve performans açısından zayıf olduğu görülmektedir.

Tesis tarafından arıtılan atık su, sulama için kullanılmamalı ve yüzeysel suya deşarj edilmemelidir.

EXAMINING PERFORMANCE OF STABILIZATION PONDS OF AHVAZ'S SLAUGHTERHOUSE

Abstract

A waste stabilization pond (WSP) is a hole in which household wastewater and other

types of sewage are stored for long periods so that organic materials existing in them are deposited,

decomposed and stabilized through exposure to light, heat, growth of algae and microorganisms. In this

study, wastewater samples collected and treated by the treatment plant of a slaughterhouse in Ahvaz

region of Iran and compared the relevant measured parameters with the standards, which set by the

Environmental Protection Organization of Iran in order to determine the efficiency of WSPs in treating

wastewater and making them usable for irrigation purposes. The results indicate that Turbidity, BOD5,

PH, COD, TDS, and TSS values for the treated wastewater stood at >1000 NTU, 912 mg/l, 8.78, 1520 mg/l,

1052 mg/l, and 2180 mg/l respectively. A comparison of these values with the standard values set by the

Environmental Protection Organization of Iran revealed a significant difference. This finding shows that

the wastewater treatment plant under study had a poor productivity and performance. The wastewater

treated by that facility should not be used for irrigation or discharge into surface water.
