Description

technical field [0001] The invention belongs to the field of wastewater treatment devices, in particular to a printing and dyeing industrial wastewater treatment device. Background technique [0002] Wastewater from the printing and dyeing industry has the characteristics of large water volume, complex composition, and serious environmental pollution. The current domestic treatment of this type of wastewater requires that the printing and dyeing wastewater be treated to meet the standards of "GB / T4287-92" before discharge. This requires the use of wastewater treatment plants. [0003] The current printing and dyeing industrial wastewater treatment devices are of various types, 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 p...

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.
