Description

technical field [0001] The invention belongs to the field of wastewater treatment devices, and in particular relates to a wastewater treatment device for printing and dyeing industries. Background technique [0002] The wastewater from the printing and dyeing industry has the characteristics of large water volume, complex composition, and serious environmental pollution. At present, the domestic treatment of such wastewater requires that the printing and dyeing wastewater be treated to meet the standards of "GB / T4287-92" and then discharged. This requires the use of wastewater treatment plants. [0003] The current printing and dyeing industrial wastewater treatment devices are various, and different methods are used to treat and purify the printing and dyeing industrial wastewater. The addition of solid additives will cause a large amount of physicochemical sludge to be produced during the wastewater treatment process, which will block the pipeline and reduce the pipeline ...

AI Technical Summary

Problems solved by technology

[0003] The current printing and dyeing industrial wastewater treatment devices are various, and different methods are used to treat and purify the printing and dyeing industrial wastewater, but the treatment and purification effect of the wastewater is not ideal, and the treatment process is always accompanied by various problems, such as Adding solid additives will cause a large amount of physicochemical sludge to be generated during wastewater treatment, which may block the pipeline and reduce the flow rate of the pipeline, or directly damage the device; The problem is that it is impossible to accurately add additives when the device is running, and stop adding additives when the device stops. Too many additives will cause waste of cost, and too little additives will not achieve the treatment effect.
