Organic wastewater catalytic degradation and separation device and method

Abstract

The invention discloses an organic wastewater catalytic degradation and separation device and method. The device comprises a dilution mechanism, a catalytic degradation and separation mechanism, a first control module and a second control module. The diluting mechanism comprises a diluting box, a stirring mechanism and a stirring driving mechanism. The catalytic degradation separation mechanism comprises a base bracket, a separation chamber, a catalytic mechanism and an aeration mechanism. The separation chamber comprises an upper separation chamber and a middle catalytic degradation chamber and a recovery chamber, wherein a titanium dioxide particle catalyst is arranged in the recovery chamber, and a separation mechanism is arranged in the upper separation chamber. The method comprises the following steps: 1, diluting organic wastewater; 2, conveying the diluted organic wastewater; 3, adding a titanium dioxide particle catalyst; and 4, carrying out catalytic degradation and separationon the diluted organic wastewater. According to the invention, dilution of organic wastewater is realized, catalytic degradation is carried out on the diluted organic wastewater, the catalytic degradation efficiency is improved, and the titanium dioxide particle catalyst can be separated and recovered.

Description

technical field [0001] The invention belongs to the technical field of degradation catalytic separation of organic wastewater, and in particular relates to a device and method for degradation catalytic separation of organic wastewater. Background technique [0002] With the continuous expansion of urban scale, the problem of water shortage is becoming more and more serious. In response to this problem, many engineering measures such as South-to-North Water Diversion have emerged. Among them, the recycling of wastewater is a relatively economical and feasible measure. However, due to the continuous development of social economy, the types of relatively stable and refractory organic pollutants produced in the industrial production process are becoming more and more abundant, and the concentration of pollutants is getting higher and higher, making the degradation of organic pollutants more and more difficult. Recycling is also facing great challenges. Photocatalytic degradatio...

AI Technical Summary

Problems solved by technology

In the supported reactor, the titanium dioxide catalyst is fixed on a certain carrier, which greatly reduces the illuminated area of ​​the catalyst and greatly reduces the catalytic efficiency; the suspension reactor has a better catalytic effect, but the separation and recovery of titanium dioxide are more difficult
