title: [Health assessment on safe treatment of night-soil on schistosomiasis endemic areas].
abstract: The family size biogas tanks were built in the study site. Their effects were monitored. Faecal coliform and parasite eggs were examined before and after biogas digestion. The results of whole-year operation indicate that faecal coliform and parasite eggs can be reduced by 99.7% and 99.8%, respectively. The schistosome eggs survival experiment showed that the eggs all died off in 100 days of retention in biogas tanks. Therefore, the appropriate technology of nightsoil treatment can effectively interrupt the life cycle of schistosome.
