摘要
在污水处理厂实验室,对二沉池出口污水进行了曝气和机械2种方式的混合絮凝对比试验。研究结果表明,对于同一水质,在相同的投药量下,曝气混凝沉淀后的水质明显优于机械混凝沉淀后的水质,各项水质指标的去除率分别提高:BOD56%~9%,COD4%~6%,NH3-N6%~9%,TP15%~24%,SS8%~18%。
Both aerated coagulation and mechanical coagulation were tested and compared in the lab of a sewage treatment company. It shows that the water quality after aerated coagulation and sedimentation exceeds the one with mechanical coagulation to a certain extent, relatively by 6 - 9 percent in BODs, 4 - 6 percent in COD, 6 -9 percent in NH3-N, 15 -24 percent in TP and 8 - 18 percent in SS.
