REUSO DO ENTULHO NO TRATAMENTO DE ESGOTO E NA RECUPERAÇÃO DE SOLOS DEGRADADOS

Abstract

this study is reported the treatment and reuse
of sewage collected of the Station of Sewage Treatment of
SANASA from Campinas (Brazil) was treated by decantation
process, using as the precipitating agent a compound
obtained from construction building waste. The resulting
sludge was used for the production of humus. Bean and corn
seeds germination and growth were used as performance
indicators. Beans and corns were chosen because they are
the staple food most widely consumed in Brazil, and the
plant grows vertically, thus hindering direct contamination.
Results showed a 100% of seed germination and an
increasing between 7-11% in soil fertility by using humus
produced from sludge composed of a mixture of crushed
construction waste and raw sewage.
