Abstract

The invention belongs to the field of wastewater treatment, and discloses a dyeing wastewater treatment device and a method for treating wastewater by using the device. The dyeing wastewater treatment device comprises a cathode chamber, an anode chamber, an ion exchange membrane and a power source. The method comprises the following steps: a double-chamber microbial electrolytic bath is established, activated sludge is inoculated in the cathode chamber, and dyeing wastewater is introduced, so that microbes are domesticated and reproduced; an external power supply is used for providing different external voltages, and the cathode potential is controlled, thereby promoting the cathode to form the specific microbial film with favorable electrochemical activity; after the pH value, hydraulic retention time, COD (chemical oxygen demand) concentration of influent water and other parameters of the wastewater are regulated, the dyeing wastewater is decolorized and degraded in the cathode chamber of the reactor, and is finally discharged out of the cathode chamber, wherein the azo dye decolorization rate reaches 90% or above.

Description

Technical field

[0001] The invention involves the field of water treatment, which specializes in a method of printing and dyeing wastewater treatment devices and the use of the device to handle wastewater. Background technique

[0002] Due to large water volume, complex composition, and large amount of organic matter that contains a lot of difficulty, it is one of the most difficult industrial wastewater. The main treatment methods of printing and dyeing wastewater include materialization and biological methods.On the one hand, the materialization method is better, but the treatment cost is very expensive. At the same time, a large number of chemicals used can also cause secondary pollution. On the other hand, the traditional biological method is due to the long cycle and the low decoration rate of the printed and dyeing wastewater, which makes it makes it allowedThe effect is unsatisfactory.

[0003] The biochemical chemical system is a new biological treatment technology, an im...
