Redox innocent treatment system and method for waste pollutants

Abstract

The invention discloses a redox innocent treatment system and method for waste pollutants. A pollutant inlet pipe, a degradation chemical agent adding pipe, a first ozone water adding pipe and a firstprecipitation blow-off pipe are arranged on a reduction reaction chamber in a communicating mode, a first ultrasonic generator is in signal connection with a low-power switch, a medium-power switch and a high-power switch in the first ozone water adding pipe, a second ultrasonic generator in signal connection with a low-power switch, a medium-power switch and a high-power switch in the second ozone water adding pipe, three stirring blades and a balance weight blade are fixedly arranged on a rotating rod, and a cleaning brush is fixedly arranged on an extension plate and used for brushing a filter screen cover. According to the redox innocent treatment system and method for the waste pollutants, the power of the ultrasonic generators can be automatically adjusted according to the flow of ozone water, the stirring blades and the balance weight blade are arranged in the system, liquid mixing can be promoted, the inlet end of a communicating pipe can be prevented from being blocked as well, and the system and method are quite worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a redox harmless treatment system and method for waste pollutants. Background technique [0002] In the prior art, the application number is "201410135939.9", an advanced oxidation-reduction harmless treatment system and method for waste pollutants, which belongs to the field of pollution control, restoration and environmental protection technology. The harmless treatment system includes a waste degradation subsystem , waste liquid treatment subsystem, ozone water preparation subsystem, degrading agent adding subsystem, detection control subsystem, water level control subsystem; The pollutants are poured into the treatment pool, and then the waste pollutants are treated with advanced oxidation / reduction reactions, and then the treated waste liquid is harmlessly treated for reuse, and then the treated soil is biodegraded. The degradation efficiency of the advanced redox h...

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. For different waste types, different reduction reactions or oxidation reactions need to be carried out, and different waste quantities and different treatment modes The amount of ozone water required is also different. In use, the ultrasonic generator needs to be used to catalyze the degradation of ozone water to generate strong oxidizing hydroxyl radicals. However, the ultrasonic generator in the above device is always at a fixed power. Not only will it cause waste of electricity when there are few processed objects, but also the long-term high-frequency use will shorten the service life of the ultrasonic generator; The waste will be precipitated after reduction treatment, causing the inlet end of the connecting pipe pump to be easily blocked by impurities, resulting in the unusable connecting pipe, and manual clearance is also more cumbersome, which affects the treatment efficiency
