Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing, in particular to a printing and dyeing wastewater purification device. Background Art

[0002] One of the main obstacles to the development of the textile industry is the issue of environmental protection and energy conservation (low carbon). The main problem of environmental protection is wastewater, and about 80% of textile wastewater comes from the printing and dyeing industry. Statistics show that in 2008, the textile industry discharged 2.3 billion tons of wastewater, ranking third among all industrial sectors, accounting for 10.60% of the national industrial wastewater discharge. The chemical oxygen demand (CODCr) in the textile industry discharged wastewater was 314,000 tons, ranking fourth among all industrial sectors, accounting for 7.76% of the national industrial wastewater CODCr. This data is a statistical data for enterprises above a certain scale, and the actual data may be much larger. In fact, the printing and dyeing industry is a competitive industry dominated by small and medium-sized enterprises, which account for 99.6%, and a large number of small enterprises are not included in the statistics. If 70% of the fiber processing volume needs to be processed by printing and dyeing, the annual wastewater discharge is about 3 billion tons. Utility Model Content
