Effect of Disinfectant on Anaerobic Degradation of Wastewater
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
A field experiment to investigate the effects of disinfectant on anaerobic degradation of sewage was carried out using wastewater. It was found that disinfectant is not completely favorable to degradation of sewage. Sewage was collected from the University Of Nigeria Nsukka treatment plant and transferred into six (6) clean four (4) Litre white bucket with mouth covered and black polythene bag to prevent the interference of sun-light and oxygen. To five (5) of the samples contained in the four (4) litre buckets , 0.5ml, 1.0ml, 1.5m, 2.0ml, 2.5ml, of each of the two (2) disinfectants (Izal and Dettol) were added with the last serving as a control sample, stirred initially and covered all through the experiment which lasted for one (1) month each. The experimental run was divided into two set, set A with Dettol dosed and set B with Izal dosed. Samples collected twice a week for analysis and the parameters checked for included: Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Fecal Coliform (FC). It was observed that addition of disinfectant on sewage can make wastewater characteristic increase the organic content present in sewage and may later decrease the degradation or make the bacteria weak.
