Abstract

In this research, works were carried out employing two identical laboratory-scale SBR inorder to investigate the effect of organic and pH shock loadings on treatment performance. The feedwastewater used was a synthetic wastewater. Two reactors were operated to reach until steady stateconditions (COD= 1000 mg/l) and first reactor was loaded with water having COD of 5000 mg/l. Thenthis organic shock loading was repeated. pH=2 and pH=12 shock loadings were applied to the reactor ata 1/10 ratio of reactor volume. Although, the reactor was affected by single organic shock loading butrecovered itself within 2 days. On the other hand, it was seriously affected by consecutive organic shockloadings and it was not able to return steady state conditions. pH shock loadings did not affect thereactor and not much change was observed on treatment performance.

Özet

Bu çalışmada laboratuar şartlarında biri kontrol diğeri ise şok yükleme uygulanan reaktör olmak üzere birbirine paralel 2 AKR kullanılarak organik ve pH şok yüklemelerin arıtım verimine etkisi araştırılmıştır. Atık su kaynağı olarak sentetik atık su kullanılmıştır.Her iki reaktör de normal şartlarda (KOİ=1000 mg/l) işletilirken 1. reaktöre KOİ=5000 mg/l organik şok yüklemesi uygulanmıştır. Daha sonra aynı reaktöre ardışık organik şok yüklemeler tatbik edilmiştir. pH şok yüklemesi ise reaktör hacminin 1/10u oranında 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 şartlarına geri dönmüştür. Ardışık olarak uygulanan organik şok yüklemeler sonrası 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.
