Pathogen treatment efficiency of anaerobic co-digestion pig dung and biomass

  • PDF

This study evaluated the treatment efficiency of microorganisms on anaerobic co-digestion from pig dung and biomass. The experiment systems used 5 L glass bottles which connected to aluminum bag for gas collection. There were 5 treatments (NT) set up randomly with treatments 1 and 2 fed 50 pig dung (PH) and 50% water hyacinth (LB) cut of 1 cm and 10 cm, respectively; treatment 3 and 4 fed 50% PH and 50% rice straw (RO) cut of 1 cm and 10 cm, respectively; and treatment 5 fed 100% PH as control treatment. All treatments were nin in 45 continuous days. The results showed reduction of worm eggs and harmful bacteria by time. The eliminating efficiencies were more than 98% for ascarid eggs, and 100% for hookworm eggs and hairworm at all treatments. The treatment efficiency of total Coliform ranged from 99.78-99.98%; Enterococcus from 95.17-99 .97%; E. coli from 99.78-99.99%; Salmonella from 76- 97.8%. The treatment efficiency was rather high but the remaining germs were still higher than discharge standards on QCVN 40:2011/BTNMT, QCVN 01-14/BNNPTNN and WHO (2006). Further study on treating of digester effluent is therefore needed to reach the discharge standards.

The results was published on the proceeding of the National Conference on Husbandry and Veterinary Science which organized at Can Tho University on April 2015. The authors are Nguyen Vo Chau Ngan, Nguyen Thi Be Gai, Nguyen Thi Thu Van.
