The activated sludge which has been

The activated sludge which has been propagated by elimination of the BOD of the raw water in this way is degraded to carbon dioxide gas and water by circulation through the sludge anaerobic tank 40, the ozone-oxidation tank 48 and the biological phosphorus-removing activated sludge treatment process 32, and so it should be discharged out of the system and the amount of excess sludge is more or less zero.
Moreover, soluble organic matter (BOD) is included in abundance in the ozone-oxidized sludge 49 as a result of the oxidative degradation of the activated sludge with ozone and so, if this is added to the anaerobic tank 33, the phosphorus release from the phosphorus-removing bacteria can be made to occur actively. Furthermore, if the sludge is left to stand anaerobically beforehand in the sludge anaerobic tank 40, the solubilization rate of the sludge is improved in the ozone-oxidation of sludge in the ozone-oxidizing tank 48.

已通过消除对 BOD 的水源，以这种方式传播的污泥退化到气体中的二氧化碳和水由循环通过污泥厌氧池 40，臭氧氧化池 48 和生物除磷活性污泥处理工艺 32，所以应该排出系统和剩余污泥量是更多或更少为零。而且在此基础上，可溶有机质 (BOD) 列入臭氧氧化污泥 49 的污泥与臭氧氧化降解而丰富，所以，如果这添加到厌氧池 33，磷释放的磷去除细菌可发生积极。此外，如果留污泥厌氧事先站在污泥厌氧池 40，臭氧氧化槽 48 中污泥的臭氧氧化提高了污泥的增溶作用率。

活性污泥已由原水这样的BOD去除传播降解为二氧化碳气体和水的循环通过污泥厌氧罐40，臭氧氧化槽48和生物除磷活性污泥处理工艺32，所以它应该排出系统和剩余污泥量或多或少是零。
此外，可溶性有机物（BOD）中包含丰富的臭氧氧化污泥49由于活性污泥的臭氧氧化降解，所以，如果这是添加到厌氧33罐，磷的释放，可以使磷的去除细菌主动发生。此外，如果污泥厌氧预左站在污泥厌氧罐40，污泥的溶解率在臭氧氧化池污泥臭氧氧化提高48。
