Abstract

The process for treating waste water uses the combination of a septic tank operating in series with a biological reactor such as a sequencing batch reactor. In this process, waste water is supplied and accumulated in a septic tank. In the septic tank, the waste water and the settling sludge are biologically treated under anaerobic conditions. A given amount of treated waste water is then transferred from the septic tank into a biological reactor such as a sequencing batch reactor, where it is mixed and aerated. Such a mixing and aerating causes activation of the sludge and clarification of the waste water. The activated sludge in suspension in the liquor is then allowed to settle and an upper layer of clarified water formed above the mixed liquor after the settling period is decanted. The excess activated sludge in the biological reactor may then be removed therefrom and supplied into the septic tank so that the excess sludge be treated by digestion therein. The apparatus used to carry out the above-mentioned process comprises a septic tank provided with a baffle wall defining a first chamber where the sludge may settle and accumulate and where anaerobic fermentation is occurring, and a second treatment chamber where the solids are anaerobically digested. In operation, the waste water may flow from the first chamber to the second chamber by passing through the baffle wall. The apparatus also comprises a biological reactor for further treating the waste water under aerobic condition. A pump is provided for transferring the treated waste water in the septic tank to the biological reactor. This process allows a total treatment of waste water and all sludge for an extended period of time, from 5 to 15 years, without having to remove any byproducts for immediate treatment.
