The invention discloses an industrial wastewater treatment system which comprises a pretreatment device, a first regulating tank, an anaerobic tank, a first sedimentation tank, a second regulating tank, an SBR reaction tank, a second sedimentation tank, a photocatalytic reaction device, a security filter and a reverse osmosis membrane filtering device which are sequentially connected through a water conveying pipeline, wherein the industrial wastewater treatment system further comprises an evaporation unit, a recycling water tank and a sludge treatment device; a concentrated water outlet of the reverse osmosis membrane filtering device is communicated with a water inlet of the evaporation unit through a pipeline; a fresh water outlet of the reverse osmosis membrane filtering device is communicated with a water inlet of the recycling water tank through a pipeline; a sludge outlet of the anaerobic tank, a sludge outlet of the first sedimentation tank, a sludge outlet of the SBR reactiontank and a sludge outlet of the second sedimentation tank are all connected with the sludge treatment device through sludge pipelines. According to the system, zero discharge of wastewater is realized, deep treatment is carried out on the sludge through the sludge treatment device, secondary pollution of the sludge to the environment is avoided, the risk of environmental pollution is reduced, andthe application market is very wide.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an industrial wastewater treatment system. Background technique [0002] Industrial wastewater includes production wastewater and production sewage, which refers to wastewater and waste liquid generated in the process of industrial production. Industrial wastewater has the characteristics of large fluctuations in water quality, complex types of pollutants, and difficult treatment. Traditional pure biochemical process routes often fail to achieve standard treatment of industrial wastewater. With the continuous development of industrial production and the continuous improvement of national environmental protection requirements, inventing an efficient, economical and stable industrial wastewater treatment process has become a new difficulty and hot spot in the field of industrial wastewater treatment. At the same time, in the context of increasingly tense global water ...
