A METHOD AND FLOW-SHEET FOR ADAPTING WASTE WATER, BEING RICH IN CALCIUM, FOR AN ANAEROBIC FERMENTATION |
| 摘要 |
<p>Waste water having undergone anaerobic fermentation is treated by reduction of partial pressure of carbon dioxide (by reduction of the gas pressure above the surface of the waste water or by stripping by carbon dioxide - free gas) in order to decompose calcium bicarbonate and precipitate calcium carbonate. The resulting water poor in calcium is used to dilute waste water ricn in calcium before anaerobic fermentation.</p> |
