Novel bean product production wastewater treating and recycling system

Abstract

The invention relates to a novel bean product production wastewater treating and recycling system. The system comprises a wastewater treatment system, a sludge treatment system and a methane recyclingsystem, wherein the wastewater treatment system comprises a grille well, an adjusting tank, a primary settling tank, a pump chamber, an anaerobic fluidized bed, an aerobic fluidized bed, an aerobic contact oxidation reactor, a secondary settling tank, an active carbon filtering tank and an air blower; a water outlet pipe of the grille well is connected with a water inlet pipe of the adjusting tank through a sewage pipeline; a water outlet pipe of the adjusting tank is connected with a water inlet pipe of the primary settling tank through a sewage pipeline; a water outlet pipe of the primary settling tank is connected with a water inlet pipe of the pump chamber through a sewage pipeline; a water outlet pipe of the pump chamber is connected with a water inlet pipe of the anaerobic fluidizedbed through a sewage pipeline; a water outlet pipe of the anaerobic fluidized bed is connected with a water inlet pipe of the aerobic fluidized bed through a sewage pipe. The novel bean product production wastewater treating and recycling system provided by the invention is high in load rate and high in capability of resisting impact load, and is capable of achieving maximum utilization of resources.

Description

technical field [0001] The invention belongs to the technical field of soybean product production wastewater treatment technology, and in particular relates to a novel soybean product production wastewater treatment and resource utilization system. Background technique [0002] As of March 2017, there were about 4,890 soy product companies in my country that had obtained production licenses, and the total amount of beans invested was about 1.2×10 6 Tons, a large amount of organic wastewater will be produced during the processing process, with high COD, BOD and ammonia nitrogen, which belongs to high-concentration industrial wastewater with high biodegradability. Wastewater mainly comes from soaked bean water, squeezed yellow pulp water and production cleaning water, among which soaked bean water and yellow pulp water constitute high-concentration organic wastewater, the total production volume is 5.5 to 7.0 times the weight of beans, and the COD value exceeds 2000mg / l. If...
