Abstract

PURPOSE: To enable invariably stable high-efficient processing by processing thick waste water containing organic matter under semiaerobic and semilight conditions.
CONSTITUTION: Thick waste water containing organic matter such as raw sewage is flowed from line 1 into incubation tanks 2a and 2b. Fresh air, oxygen or gas containing oxygen coming from line 7 is mixed by mixer 10 with gas exhausted from tanks 2a and 2b via exhaust lines 20a and 20b. This mixed gas is dispersed into the waste water in tanks 2a and 2b by sparger 6a and 6b by way of feed lines 19a and 19b to stirr the waste water. In this case, O2 concentration in the mixed gas is controlled. Tanks 2a and 2b are irradiated with light to incubate purple nonsulfur bacteria with organic matter in the waste water, thereby decomposing and removing organic matter in the waste water. Here, seed germs are supplied via line 27.
