Özet
Bu çalõşmada laboratuar şartlarõnda biri kontrol diğeri ise şok yükleme uygulanan reaktör olmak üzere birbirine paralel 2 AKR kullanõlarak organik ve pH şok yüklemelerin arõtõm verimine etkisi araştõrõlmõştõr. Atõksu kaynağõ olarak sentetik atõksu kullanõlmõştõr.Her iki reaktör de normal şartlarda (KOİ=1000 mg/l) işletilirken 1. reaktöre KOİ=5000 mg/l organik şok yüklemesi uygulanmõştõr. Daha sonra aynõ reaktöre ardõşõk organik şok yüklemeler tatbik edilmiştir. pH şok yüklemesi ise reaktör hacminin 1/10 u oranõnda pH= 2 ve pH=12 olan suyun ani olarak reaktöre verilmesi şeklinde gerçekleştirilmiştir. Sistem, uygulanan birinci şok yüklemeden etkilenmiş ancak 2 gün içerisinde normal işletme şartlarõna geri dönmüştür. Ardõşõk olarak uygulanan organik şok yüklemeler sonrasõ ise sistemde çamur çökelme özellikleri bozulmuş ve sistem normal haline geri dönememiştir. Uygulanan pH şok yüklemeler sistemi fazla etkilememiş ve arıtma veriminde önemli değişiklikler oluşturmamıştır.
In this research, works were carried out employing two identical laboratory-scale SBR in order to investigate the effect of organic and pH shock loadings on treatment performance. The feed wastewater used was a synthetic wastewater. Two reactors were operated to reach until steady state conditions (COD= 1000 mg/l) and first reactor was loaded with water having COD of 5000 mg/l. Then this organic shock loading was repeated. pH=2 and pH=12 shock loadings were applied to the reactor at a 1/10 ratio of reactor volume. Although, the reactor was affected by single organic shock loading but recovered itself within 2 days. On the other hand, it was seriously affected by consecutive organic shock loadings and it was not able to return steady state conditions. pH shock loadings did not affect the reactor and not much change was observed on treatment performance.
