Abstract

Sludge composting is an effective method of urban sewage sludge by composting,It can make the sludge into the organic fertilizer for plant growth. In this experiment, straw as bulking agents, through aerobic composting experiment, analysis the changes of temperature, moisture, pH, water soluble organic carbon and germination index during the composting process,The results showed: through aerobic composting can achieve for urban sludge harmless, stabilization and reduction.
