The research of square internal circulation anaerobic reactor to treatmenting soybean protein wastewater

The square internal circulation anaerobic tank is square, reinforced concrete structure, compared with the traditional IC reactor, it has high insulation feature, good corrosion resistance, lower height, simple systemic internal structure, less water loss, small lift head, suitable for high concentrations of organic wastewater treatment and so on. When using the process based on the square IC reactor to treat the soybean protein wastewater, higher COD removal rate and greater volume flow can be achieved, while the running status reached to a certain range, a continued strong internal circulation was formed in the internal circulation pipe of the square reactor tanks. When the water quality and treatment systems reached the same level, the lifting cost of new reactor sharp decreased compared to the traditional IC reactor.
