| titleOfInvention | METHODS FOR CLEANING UP WASTE WATER |
| abstract | Chemical and biological purification of waste waters by introducing O2 is effected by (1) using as O2-source, highly concentrated, e.g. 80-85%, H2O2 which is either (ae mixed directly with the concn. waste water in a container of suitable material, e.g. pure Al or plastic-lined material; is catalytically decomposed in the presence of heavy metals with nascent O reacting immediately with the waste water to be purified or, (b) in the absence of catalytically active substances, is decomposed directly before entry into container by means of suitable catalysts; (2) in order to enrich the waste water with O2 for biological purification, the H2O2 is decomposed by suitable catalysts before entering receiving stream and the supply of O2-enriched water into biological clarification plant system takes place only after re-combination of nascent O to O2. |
