Abstract
I takt med at den komplekse spildevandsproduktion i det moderne samfund stiger, kræves der forbedringer af behandlingsteknologien for at sikre bæredygtig udvikling, især inden for nitrifikationsprocesser, som spiller en vigtig rolle i spildevandsrensningsanlæg. Imidlertid er mikroorganismer, som er baseret på nitrifikationsprocessen, følsomme over for visse giftige stoffer, der påvirker kvaliteten af udløbsvandet. Hovedformålet med denne undersøgelse er at indsamle og konkludere litteratur om NI (nitrifikationshæmning) og kontrollerede eksperimenter med lossepladsperkolat, der forårsager NI-graden, efter analysetype - ammoniakkonverteringshastighed. Det kontrollerede eksperiment på ATU (N-Allylthiourea) har til formål at bevise effektiviteten af denne analysemetode. I litteraturgennemgangen er kilder til NI, analysetyper og nitrifierresistens overvejet. De viste, at denne batch af lossepladsperkolat ikke kunne forårsage NI. Det foreslås, at klassificering og begrænsning af spildevandskilder garanterer mikroorganismernes sikkerhed.
While increasing complex wastewater produced in modern society, the technology of treatment is demanded improvement to be suitable sustainable development, especially in nitrification processes, which plays an important role in wastewater treatment plant. However, microorganism, nitrification process relied, is sensitive to some toxicant affecting quality of outlet water. The main objective of this study is collection and conclusion of literature about NI (nitrification inhibition), and controlled experiment on landfill leachate causing NI degree by assay type - ammonia conversion rate. The controlled experiment on ATU (N-Allylthiourea) is to prove the effectivity of this assay method. In literature review, it’s considered sources of NI, assay types and nitrifier resistance. They showed this batch of landfill leachate couldn’t cause NI. It’s suggestion that classification and limitation of wastewater sources guarantee security of microorganism.
