10 In the period August 1999 - October 2000, a measurement programme has been carried out. The results show that the cleaning ability of the plant was good with regard to removal of organic material. Removal of nitrogen was, as expected, best during the summer period. Measured at the outlet, the removal of phosphorus was 26% and a concentration of an average of 8.22 mg/litre. The experience from the plant has proved that in order to obtain an acceptable quantity of phosphate in the discharge the households must use detergents of a good quality and with a low concentration of phosphate for machine washing. Such interventions in the consumption patterns, which are necessary by utilization of green waste water treatment plants, are often done by general norms for the contents of phosphate in detergents. The inlet of waste water was on the average 687 litres/day. A great part of the cleaned water was used for growing of hydrophytes and breeding of cyprinid. Some of the water was used for watering the local lawns. The plant was built by FC staff and professional craftsmen. The operation work has been carried out by employees using about 10 to 20 minutes a day. The plant increment was harvested several times during the growing season (about every six weeks). As from August 1999, several thousands of visitors have seen the plant. Furthermore, the plant has been mentioned several times in various magazines and TV broadcastings. Twice the plant has been used directly as a teaching topic for pupils from public and grammar schools. In September 1999 and December 2000, FC organized a “Meeting on green waste water treatment”. From this it can be concluded that the plant has had a great demonstration value.
1 Indledning Behovet for undersøgelse af alternative spildevandsrensnings anlæg er stort og permanent. Vores "Water for Life" anlæg er et af projekterne i Miljøstyrelsens ”Aktionsplan for fremme af økologisk byfornyelse og spildevandsrensning”, under temaet ”Økologisk håndtering af spildevand i det åbne land”, hvor der er taget hensyn til udnyttelse af næringssalte samt genbrug af vand. Denne rapport handler om, på hvilken måde vi har etableret anlægget, hvordan anlægget fungerede under forsøgsperioden, samt resultater af måleprogrammet. Anlægsbeskrivelsen er udarbejdet som en slags vejledning, hvor man nemt selv kan finde ud af, hvordan anlægget sammensættes. 11
