摘要
在中温35℃条件下,考察了升流式固体反应器(USR)用于处理猪场养殖废水时的运行情况及影响因素,确定了合适的运行条件.实验结果表明,USR对COD的去除率可达90%,所产沼气中的甲烷含量可达60%;从而确定采用USR处理高浓度、高悬浮物的养殖废水是一种经济可行的方法.
An experimental study on piggery wastewater treatment is presented by upflow solid reactor （USR） in 35℃. The operation and the influence factor about the USR are studied, and the optimum operation conditions on the system are ensured. The experimental results show that the COD removing rate increasesd to 90%, and the average amount of CH4 is 60% in firedany gotted. It is an economical feasible method to treat the high concentration, the high suspension livestock wastewater by USR.
