  • BIOLOGICAL DENITROGENATION METHOD USING SLOW RELEASE SOLID CARBON SOURCE
    Publication number: 20150175456
    Abstract: Disclosed is a method for biological denitrification of water body polluted by nitrates using sustained-release solid carbon sources comprising the following steps: add cassava lees into water body polluted by nitrates for denitrification of the waste water, It can achieve the purpose of biological nitrogen removal through slowly releasing organic carbons as carbon sources for microbial denitrification in the water by cassava lees and the cassava lees losing the carbon-releasing function can be naturally degraded in the environment without causing secondary pollution.
