<p>The present invention provides an odour controlled waste water treatment system for sewage, domestic effluent and the like. The system (1) comprises a tank (2) having at least three processing chambers including a first chamber (3) for an aerobic treatment of the waste including therein a first head space (6) and an inlet (7) to receive the untreated waste, a second chamber (4) for aerobic treatment of the product from the first chamber (3) and including therein a second head space (8), a third chamber (5) for sterilisation of the product of the second chamber and including therein a third head space (9), means to prevent back flow of liquid and gas from said second chamber to said first chamber, means (15) to admit air into said second head space, means (17 and 18) to extract air from said second head space to generate and deliver ozone to the waste product in said third chamber, and means (40) to extract substantially deodorised gas from said third head space.</p> |
