1. Inhibition of Nitrification in Industrial Wastewater - Identification of Sources
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The discharge of industrial wastewaters (WWs) to wastewater treatment plants (WWTPs) can be problematic due to their sometimes elevated concentrations of toxic compounds compared to municipal wastewater. Also, industrial WWs often contain compounds that are unique to the specific production, and the receiving WWTP is not always designed to remove these compounds. LÄS MER
2. Organogena jordar : hur man kan minska markytesänkning och växthusgasemission
M1-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Odlade organogena jordar motsvarar idag ca 7 % av den svenska jordbruksmarken. Genom dränering av tidigare våtmarker har de gått från att ackumulera kol till att släppa ut kol i form av koldioxid. LÄS MER
3. Nitrifikationshämning i tvätteriavloppsvatten
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The nitrification process is known to be the most sensitive link in biological nitrogen removal used in many wastewater treatment plants. Many different inhibitory substances can disturb these sensitive bacteria and in that way cause reduced nitrogen removal. LÄS MER
4. Behandling av lakvatten med kemiska oxidationsmedel för att delvis bryta ned oönskade organiska förening : en studie utförd vid Hovgårdens avfallsanläggning i Uppsala
L3-uppsats, SLU/Dept. of Biometry and EngineeringSammanfattning : A renewed application for environmental permit for the Hovgården landfill in Uppsala shall be submitted before December 2004, therefore the municipality of Uppsala needs improved knowledge of the contents, mostly organic compounds in the leachate and they also want to find a method to minimize the emissions of these compounds. The purpose of this study was to find a practical and economical method based on chemical oxidation using oxidants. LÄS MER
