Sewage treatment plant has a continuous aerobic reactor, and a thermal reactor, to process the sewage with a reduction in waste |
摘要 |
The sewage treatment plant has a reactor where the sewage is fermented continuously and biologically, in a reactor (1) with an aerobic action on the watery sewage to form a reaction mixture as a biomass. Part of the mixture is taken continuously for ultrafiltration (4). The permeate is extracted and the retentate is recirculated in the reactor to maintain a constant reaction volume. All or part of the mixture is taken off at intervals to a reactor (11), for a heat treatment at a temperature of 50-100degreesC, together with an alkaline treatment and a stirrer (14), to give a bacterial lysate recycled back to the aerobic reactor by a pump (P) through a heat exchanger (10). |
