Background
Tofu is the most common bean product, and is classified into south bean curd and north bean curd. The main difference lies in that coagulants used in the curdling process are different, southern bean curd is curdled by using gypsum, and the curdled bean curd obtained by the curdled method has high water content, water content of about 90 percent and delicate texture; the northern bean curd is prepared by more brine, the water content of the solidified beancurd jelly is less, about 85 percent, and the flexibility is enhanced. A large amount of organic wastewater can be generated in the production process of bean curd, the amount of wastewater generated by processing one ton of soybeans into bean curd is about 7-10 tons, the Chemical Oxygen Demand (COD) of the wastewater is 10-20 mg/L, and the Biological Oxygen Demand (BOD) is also not a little. The bean curd waste water contains monosaccharide, oligosaccharide, vitamin, organic acid, amino acid, lipid, lactalbumin, isoflavone, P, Ca, Fe, Mg and other nutrients.
At present, domestic bean curd wastewater treatment is mainly concentrated on an upflow anaerobic sludge fluidized bed (USAB), a microalgae culture method, an activated sludge method, a Sequencing Batch Reactor (SBR) and other processes. Among them, the anaerobic process is suitable for the treatment of high concentration organic wastewater, but the anaerobic treatment method cannot remove biological nitrogen and phosphorus, and the pH needs to be continuously adjusted in the treatment process; the aerobic treatment process needs to meet the requirements of nitrogen and phosphorus removal and sludge concentration, and the treatment process not only wastes organic carbon and nutrient resources, but also produces carbon dioxide and sludge, so that the resource recycling can not be realized to the maximum extent.
