Claims (15)
1. Fremgangsmåde til rensning af spildevand, hvor spildevandet underkastes en behandling i et første område for at udfælde fosfor i en septiktank, hvorefter det spildevand, som er tømt for fosfor, ledes successivt gennem to gen-nemluftede biofiltre, som hver især i en tank danner adskilte områder, i hvilke det første biofilter hovedsagelig optager heterotrofe bakterier og det andet biofilter hovedsagelig autotrofe bakterier, hvor spildevandet tømmes fra det andet biofilter, hvilken fremgangsmåde er kendetegnet ved, at slam og renset vand, som er nitratrig, fjernes flere gange i løbet af dagen og genbruges fra det andet gennemluftede biofilter til septiktakindgangen.
2. Fremgangsmåde ifølge krav 1, omfattende: - opsamling af spildevand i en septiktank - rensning i mindst 2 afsnit, fortrinsvis mindst 3 afsnit, hvor hvert afsnit har et nedsænket gennemluftet filter og et slamudfældningstrin, hvor fremgangsmåden er kendetegnet ved, at vand og/eller slam genanvendes fra et eller flere afsnit, og at strømmen af spildevand gennem anlægget eventuelt styres.
3. Fremgangsmåde ifølge et af kravene 1 eller 2, hvor en jævn belastning af anlægget sikres ved at anvende en elektronisk styret pumpe.
4. Fremgangsmåde ifølge et af kravene 2 eller 3, hvor denitrificering og udfældning af fosfor udføres i septiktanken under anvendelse af en tilbagestrømning fra det sidste slamudfældningstrin.
5. Fremgangsmåde ifølge krav 4, hvor en fosforudfældning tilføjes i tilbagestrømningen.
6. Fremgangsmåde ifølge et af kravene 1-5, hvor den tilsatte mængde fosforudfældningsmiddel indstilles ved at tage tilførslen af fosforholdige forbindelser og mængden af nitrat i det genanvendte rensede vand i betragtning.
7. Fremgangsmåde ifølge et af kravene 2-6, hvor den tilbageførte slam anvendes til at presse spildevand fra septiktanken til rensningsafsnit.
8. Fremgangsmåde ifølge et af de foregående krav, hvor den genanvendte mængde vand svarer til den normale daglige tilførsel af spildevand.
9. Rensningsanlæg, som omfatter en septiktank, et første afsnit med et gen-nemluftet biofilter, et andet afsnit med et gennemluftet biofilter, hvor afsnittene danner adskilte områder, i hvilke det første biofilter hovedsagelig optager heterotrofe bakterier og det andet biofilter hovedsagelig autotrofe bakterier, kendetegnet ved, at en luftfordelingsenhed er anbragt under filterelementet, og at anlægget har genanvendelsesmidler til genanvendelse af renset, nitratrigt vand og midler til genanvendelse af slam, der er udfældet i eller efter biofiltrene til septiktanken.
10. Rensningsanlæg ifølge krav 9, kendetegnet ved, at det omfatter en septiktank efterfulgt af mindst 2 afsnit, fortrinsvis mindst 3 afsnit, som hver især omfatter et hovedkammer med et nedsænket biofilter, hvor afsnittene danner adskilte områder og en bundfældningstank, kendetegnet ved, at anlægget har midler til at genanvende nitratrigt vand og/eller slam fra en eller flere af bundfældningstankene til septiktanken.
11. Rensningsanlæg ifølge krav 10, kendetegnet ved, at, og ved eventuelt at have midler til at styre strømmen af spildevand gennem anlægget.
12. Rensningsanlæg ifølge et af kravene 10-11, kendetegnet ved, at det omfatter mellem 3 og 5 afsnit, som hver især omfatter et hovedkammer med et nedsænket biofilter og en bundfældningstank.
13. Rensningsanlæg ifølge et af kravene 10-12, kendetegnet ved, at det omfatter midler til at lede vandet tilbage fra det sidste afsnit.
14. Rensningsanlæg ifølge et af kravene 10-12, kendetegnet ved, at det omfatter midler til afgivelse af et middel til udfældning af fosfor.
15. Anvendelse af en rensningsenhed, hvor rensningsenheden omfatter et første afsnit med et gennemluftet biofilter, et andet afsnit med et gennemluftet biofilter, hvor afsnittene danner adskilte områder, i hvilke det første biofilter hovedsagelig optager heterotrofe bakterier og det andet biofilter hovedsa gelig autotrofe bakterier, hvor rensningsenheden har en luftfordelingsenhed, som er anbragt under filterelementet, og genanvendelsesmidler til genanvendelse af renset vand og midler til genanvendelse af slam, der er udfældet i eller efter biofiltrene til septiktanken.
