| Abstract |
Stationary sloping screens were used to remove up to 75% of the solids in diluted dairy cattle manure. Two bench-scale aerobic treatment systems were then used to treat screened effluent. Two replicate systems, one using distilled water and one using system final effluent to dilute incoming manure were used to determine the effects of renovated water reuse. BOD reductions greater than 95% and COD reductions greater than 90% were obtained in all systems. No adverse effects of water reuse were found. Phosphate level was not affected and there was no appreciable build-up of fecal coliform or fecal streptococcus. A one-cow scale modified activated sludge system was used to treat 120 pounds of manure and 66 gallons of dilution water daily for more than six months. The final effluent was disposed of by a sub-surface irrigation system. Plastic nozzles were found satisfactory to release the liquid to the soil. (Author) |
