Abstract

According to the beer effluent treatment plant preliminary design process. Beer wastewater containing many organic substances, these high organic concentration, although non-toxic, but easy to corruption, discharged into the water body will consume large amount of dissolved oxygen, causing serious pollution of water environment.

The value of BOD5\CODcr of brewery wastewater is high, in the 50% and above, is very conducive to biochemical treatment. At the same time, biochemical treatment and physical method, chemical method are compared; one is processing technology more mature; two is the high treatment efficiency, high removal rate of CODcr, BOD5, generally up to 80%~90%; three is the low processing cost (cost); after comparing the various treatment processes, the final choice of hydrolytic acidification-biological contact as the process of oxidation.

This process is arranged in the grid, regulation pool, pretreatment of wastewater, the removal of larger particles suspended in the water and water quality regulation. Biological treatment by biological contact oxidation method, can improve the removal efficiency of organic compounds. Sedimentation tank for slurry separation.

This simple process stability, change of water flow, water quality has a strong ability to adapt, while ensuring that the effluent COD, BOD and SS as well as the total nitrogen, total phosphorus index reaches the standard. Through the preliminary budget, this process will bring considerable economic benefits and environmental benefits.

Regulation pool, the grille, hydrolysis tank, biological contact oxidation tank, sedimentation tank, sludge tank main structures are calculated, prepare the design specification, and rendering process, structures plane and elevation, the
