Embodiment Construction

[0020] The catalytic electrolysis coupling reactor of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] The design of the catalytic electrolysis coupling reactor is based on the combination of the traditional fixed iron internal electrolysis bed and the three-dimensional electrode reactor, with the vertical cylinder as the main reaction vessel, and the internal electrolysis, ultrasonic and electro-Fenton three These water treatment technologies are coupled in series into one. The reactor can effectively treat difficult biodegradable organic waste water. A water inlet pipe (1) is provided at the bottom of the reaction vessel to communicate with the water inlet area (3), and a mud discharge pipe (2) is provided at the bottom of the water inlet area (3) to discharge the iron mud washed from the iron inner electrolytic bed from the bottom exclude. An air distribution pipe (4) is arranged on the upper part of the water i...

Abstract

The invention relates to a catalytic electrolysis coupling reactor which is suitable for treating various organic wastewater, especially organic wastewater difficult to be bio-degraded. The reactor consists essentially of an iron internal electrolytic layer, an ultrasonic irradiation layer and a three-dimensional electrode oxidation layer which are coupled and connected in series from bottom to top; water treatment technologies such as traditional internal electrolysis, ultrasonic wave and an electricity-Fenton method are coupled to treat the organic wastewater difficult to be bio-degraded soas to lead the organic wastewater to stably reach standard; and the catalytic electrolysis coupling reactor not only can be applicable to pretreatment of various organic wastewater which has high concentration and is difficult to be bio-degraded so as to greatly reduce the concentration of organic pollutants and improve the biodegradability of the wastewater, but also can be applicable to main treatment units for wastewater with small volume of flow so as to lead the treated wastewater to directly reach the standard and be discharged.

Description

technical field [0001] The invention belongs to the technical field of catalytic oxidation water treatment in environmental chemical engineering, and in particular relates to a multi-level catalytic electrolysis coupling reactor which can be used to treat organic waste water, which is suitable for the degradation and oxidation of various organic waste water, and is especially suitable for the treatment of refractory organic waste water. deal with. Background technique [0002] The prevention and control of industrial wastewater pollution is an important factor affecting the sustainable development of the national economy, the sustainable preservation and sustainable utilization of natural resources. A large part of the industrial wastewater that causes pollution is difficult to treat organic wastewater. This type of wastewater mainly comes from organic wastewater including pesticides, printing and dyeing, and chemicals, all of which contain toxic and highly stable pollutant...
