摘要
本文对标准胶加工废水和氧化塘种殖的水葫芦厌氧发酵制取沼气进行了研究。结果表明，水葫芦是一种良好的沼气发酵原料，批量发酵每克干物质可生产沼气０－３４４ Ｌ。常温下，水葫芦预发酵后与废水按１∶３ 比例（ 以ＣＯＤ计） 混合连续发酵，混合液每克ＣＯＤ 可生产沼气０－５５６ Ｌ，容积产气率达１－７８ Ｌ／（Ｌ·ｄ） 。
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).
