Abstract

Abstract

Leachate from municipal solid waste incineration plants is a kind of refractory wastewater with a high concentration of ammonia nitrogen and organic matter. Multi-stage nitrification and denitrification process is often used for biological denitrification of leachate, which has the disadvantages of high energy consumption and low efficiency. In this study, a continuous flow three-stage process of anaerobic digestion-partial nitrification-anammox was establish to treat the leachate with the anammox process as the key technology, and its biological denitrification effect, changes of organic matters, functional microbial activity and composition analysis of leachate from waste incineration plant were investigated. The results showed that when the influent NH₄⁺-N and COD concentrations were 900~1800 mg/L and 3000~20000 mg/L, respectively, and the total inorganic nitrogen (TIN) and COD removal efficiency reached 85% and 77%, respectively. Specifically, the COD removal efficiency was about 45% in the anaerobic digestion reactor. The accumulation rate of NO₂^--N in the partial nitrification reactor remained 97% above, and the removal efficiency of total inorganic nitrogen was about 85% in the Anammox reactor; heterotrophic denitrification also had occurred in the system. The activity of ammonia oxidizing bacteria and anammox bacteria in the autotrophic nitrogen removal system decreased in varying degrees after the leachate added. The results of metagenomics combined with 16S rDNA high-throughput sequencing analysis showed that the relative abundance of heterotrophic denitrifiers in the partial nitrification and Anammox reactors increased, due to the high concentration of organic matters in the leachate. Specially, Anammox was inhibited by refractory organics, among which Candidatus_Kuenenia was adaptable. Nevertheless, after a long-term acclimation, the anammox bacteria could still maintain a high nitrogen removal efficiency.
