MBBR process for treatment of high ammonia nitrogen industrial wastewater and its advantages

1.Characteristics of industrial wastewater

1) .The industry is very different

2) .The composition of the ingredients is very complex, some molecules are difficult to degrade and are very toxic

3) .Some sewage has very high salinity, with a concentration of 50g/l or even higher

4) .The impact load is large and can reach the peak value in a short time

5).The physical and chemical processing requirements at the front end of the biochemical processing are very high

2.Nitrification of industrial wastewater

The biochemical removal of nitrogenous substances in industrial sewage is also very important, because excessive nitrogen is one of the important reasons for eutrophication of water bodies, and nitroso is a carcinogen.
