Solution for Bean Products Wastewater

Treatment process of soy product wastewater

Bean product wastewater is a highly concentrated organic wastewater containing organic compounds such as protein, fat, starch, etc. It has good biodegradability and is suitable for treatment using biological treatment methods.

3.1 Anaerobic method

There are many anaerobic methods used to treat soybean wastewater both domestically and internationally. Anaerobic sulfurization bed technology is used to treat soybean wastewater, anaerobic baffle reactors are used to treat soybean wastewater, and multipole anaerobic biofilters are used to treat organic wastewater with high soybean concentration, which is both economical and cost-effective. Practice has proven that using a multi-stage anaerobic biofilter to treat high concentration organic wastewater is significantly superior to the single-stage anaerobic biofilter process,CODcrThe removal rate is determined by 78%～80%Raise to 90%The above. This method is a multipole anaerobic biofilter applied in engineering practice———Aerobic process.

3.2 Aerobic method

Based on the characteristics of soy product wastewater, measures can be taken to ABThe activated sludge process is used for treatment. Obtained through process testing ABThe operating parameters of the activated sludge process for treating soy product wastewater were optimized in the experiment, and significant treatment effects were achieved,CODcrThe total removal rate of effluent is97%Among themAThe segment removal rate is 89%，BThe segment removal rate is 83%.

3.3 anaerobic—Aerobic method

anaerobic—The aerobic treatment process can leverage the advantages of anaerobic microorganisms in carrying high concentrations, high loads, and recovering effective energy, while also utilizing the fast production speed and good water quality of aerobic microorganisms.
