豆制品废水是一种严重污染环境的高浓度有机废水,其COD值一般在1～3万㎎/1,其中大部分为易于生化处理的有机物,且有30～50℃的温度,因此也是厌氧发酵回收部分能源的极好原料。但是对于数量众多,分布面很广的中小城市及县镇来说,此类工厂多半规模较小,厂址分散,日排放量 Soybean waste water is a highly polluted organic wastewater with a high COD value of 1 to 30,000 ㎎ / 1, most of which is easily biodegradable and has a temperature of 30 to 50 ° C Oxygen fermentation part of the excellent energy recovery of raw materials. However, for a large number of medium and small cities and counties with a large distribution area, most of these factories are small-scale, with scattered sites and daily emissions
