The invention discloses a dye wastewater treatment system and method. A liquid outlet pipeline of an existing regulating pool is connected with a liquid inlet of a cooling tower, a liquid outlet of the cooling tower is in pipeline connection with a liquid inlet of an anaerobic pool, a liquid outlet of the anaerobic pool is in pipeline connection with a liquid inlet of a primary oxidation pool, a liquid outlet of the primary oxidation pool is in pipeline connection with a liquid inlet of a primary sedimentation pool, a liquid outlet of the primary sedimentation pool is in pipeline connection with a liquid inlet of an efficient biological filter, and a liquid outlet of the efficient biological filter is in pipeline connection with a liquid inlet of a clean water pool. The method comprises the steps that S1, dye wastewater is cooled, the cooled dye wastewater enters the oxygen-free environment so that anaerobic microorganisms can move, and then the dye wastewater is degraded; S2, the dyewastewater enters an aerobic environment so that aerobes can move, and then the dye wastewater is degraded secondarily; S3, the settled dye wastewater is filtered through the microorganisms so as to decompose organic matter in the dye wastewater. The system is low in energy dissipation, small in size, low in maintenance cost and high in purification capability.
Description
technical field [0001] The invention relates to the technical field of dye wastewater treatment, in particular to a dye wastewater treatment system and method. Background technique [0002] With the development of textile printing and dyeing industry, the impact of printing and dyeing wastewater on the environment is increasing, and the research and development achievements of printing and dyeing industrial wastewater treatment are also being continuously transformed and applied. Due to the complex water quality of dye production wastewater, there are various ways to treat it. At present, most domestic sewage treatment equipment is designed for large state-owned enterprises, with huge equipment and complicated systems. For many small and medium-sized printing and dyeing enterprises in their infancy , basically unable to afford the complex and high cost of wastewater treatment. Therefore, for many small and medium-sized printing and dyeing enterprises at present, it is neces...
