摘要
由于矿区生活污水中有机污染物浓度较低，采用活性污泥法处理工艺，有机污染物在生物氧化池内得到较彻底地降解，剩余污泥量少，每千吨生活污水产生剩余污泥量为2～3t。
Because the concentration of organic pollutant in sewage of mine districts is lower, the pollutant could be degraded thoroughly in the biologic reaction tanks. The amount of residual sludge is very low. One thousand tons of sewage can produce about three tons of residual sludge.
