ANAEROBIC PURIFICATION OF WASTE WATER CONTAINING SULPHATE AND ORGANIC MATERIAL |
摘要 |
<p>Waste water containing sulphate and organic material is treated in a two-step anaerobic biological plant in two fluidized-bed reactors. In the first reactor (1) (acidification stage) at least 80 % of the sulphates are reduced to hydrogen sulphide which is then removed for at least 70 % in a gas stripper (13) by a purge gas (12). The effluent from the stripper (13) is then digested in the second (methanic) reactor (22).</p> |
