Ruthenium-iridium-titanium anode for landfill leachate
Sanitary landfill is one of the main treatment methods of urban waste in my country. The resulting landfill leachate is a kind of difficult-to-treat high-concentration organic waste water. . Generally, after biological treatment of landfill leachate, the residual COD is still high, some as high as 600-800 mg/L, and it is difficult to reprocess.
The harmless treatment of leachate has always been a difficult problem. Since landfill leachate is a kind of high-concentration organic wastewater that is difficult to treat, it has strong toxicity, complex components, high COD and ammonia nitrogen content, serious imbalance in the proportion of microbial nutrients, and poor biodegradability. Therefore, the treatment method of leachate is one of the key issues in landfill design and operation management. Reasonable selection of the leachate treatment process is very necessary for the sanitary landfill treatment of municipal waste. Due to its strong selectivity, electrochemical water treatment technology can convert refractory organic substances or pollutants that are toxic and inhibited to organisms into biochemical substances, thereby improving the biodegradability of wastewater. Electrolysis can indirectly oxidize landfill leachate.
