Study on Anaerobic Treatment of SCR Processing Wastewater and Water Hyacinth

In this paper the preparation of methane from the anaerobic fermentation of the wastewater from Standard Chinese Rubber(SCR) processing and the water hyacinth planted in the oxidation pond were studied. The results show that the water hyacinth is a good methane fermentation material. In the batch fermentation a gram of dried water hyacinth can produce 0 344?L methane. At room temperature, by mixing the pre fermented water hyacinth with wastewater in a ratio of 1∶3 (calculated in COD), a gram of COD of the mixture can produce 0 556?L methane in a continuous fermentation. The volumetric output of methane is 1 78/(L·d).
