The result has shown that the pre-coagulation treatment has the effect to the COD of the wastewater, ore than 60%.
试验结果表明，絮凝预处理对啤酒废水的COD的处理效果可以达到60%以上。
2
Porosity increases along with the increasing of coagulation bath temperature, and doesn't have relation to pre-evaporation.
孔隙率随着凝固浴温度的上升而上升，而与预蒸发时间的长短没有关系；
3
The retention rates of Albumin bovine decreases when coagulation bath temperature increases, and first decreases, then increases when pre-evaporation time prolongs.
