Embodiment Construction

[0009] refer to figure 1 , the specific implementation mode adopts the following technical scheme: its processing technology is:

[0010] 1. Filter the wastewater, and the filtered wastewater is divided into filter residue and filtrate; 2. The filter residue is subjected to adsorption process, and different types of usable substances are sorted out for recycling; 3. If the filtrate is non-polluting filtrate or conventional filtrate, It is directly imported into the sedimentation tank, and if the filtrate is organic filtrate or heavy metal filtrate, then it is imported into the titanium anode electrolyzer; 4. Add alkaline medium and acidic medium respectively in the sedimentation tank and titanium anode electrolyzer to change the pH value of the filtrate ; 5. The filtrate after the electrocatalytic oxidation of the titanium anode electrolytic cell is introduced into the sedimentation tank for treatment; 6. The filtrate after precipitation can be recycled as water.

Abstract

The invention discloses an application of titanium anode in high-concentration industrial wastewater treatment, which relates to an application of titanium anode. The treatment process comprises the following steps of: 1, filtering wastewater, and separating the filtered wastewater into a filter residue and a filtrate; 2, treating the filter residue by adsorption process, and sorting out the usable materials of different types and then recovering; 3, if the filtrate is a pollution-free filtrate or a conventional filtrate, then directly leading the filtrate in a sedimentation tank, and if the filtrate is an organic filtrate or a heavy-metal filtrate, then leading the filtrate in a titanium anode electrolytic cell; 4, adding an alkaline medium and an acidic medium in the sedimentation tank and the titanium anode electrolytic cell respectively, so as to change the pH value of the filtrate; 5, leading the filtrate electro-catalytically oxidized in the titanium anode electrolytic cell in the sedimentation tank and then treating; and 6, discharging the sedimentated filtrate and recycling. The application of titanium anode in high-concentration industrial wastewater treatment saves water resource, has low power consumption, and decreases enterprise cost.

Description

Technical field: [0001] The invention relates to the application of titanium anodes, in particular to the application of titanium anodes in the treatment of high-concentration industrial wastewater. Background technique: [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. For the protection of the environment, the treatment of industrial wastewater is more important than the treatment of urban sewage. Although the treatment of industrial wastewater started as early as the end of the 19th century, and a large number of experimental studies and production practices were carried out in the following half century, due to the complex composition and changeable nature of many industrial wastewater, there are still some technical problems that have not been completely resolved. . [0003] At present, the...
