wastewater
Background
Producing 1 t beer will consume 10~30m3 fresh water and discharge 10~20m3 wastewater.
The concentration anic matter is thousands times more than the life wastewater.
With the improvement of brewery industry, the production had reached 30million per year in China, more than the .
Along with the expansion of the scale of the brewery factories, the discharge of brewery wastewater is also increasing.
