| Abstract: | The system consists of three preliminary clarifiers and two ponds operating in series. It drains 100,000 to 120,000 m3 highly loaded wastewater per year over the ground. In dependence on load, in the pond 1 a midsummer-time bacterial maximum of up to 800 m3/l occurs. The algal biomass, too, shows an annual curve with one peak; the maximum is independent of the ice cover and varies with the seasons. The BOD5 shows a spring maximum and a summer maximum independent of the biomasses and their variations. In the second pond only slight changes are found from June till October; here prevail algae and a maximum of flagellates. Although a stage of filtrators and consumers is lacking, the system can be regarded as a sewage pond system with a reduction of BOD5 by 73%. |
