[0003] In the process of hydrolysis and acidification treatment of sewage, the prior art requires the use of a stirring device to stir and mix the sewage, sludge and auxiliary flocculation particles in the sewage pool so that the sewage can be quickly treated. This will result in more internal structures in the sewage pool, occupying a large space, which is not conducive to later maintenance. In addition, the sludge is easily taken out of the sewage pool during the drainage process, causing the internal sewage treatment system to be unbalanced, and the sludge and auxiliary flocculation particles need to be added again, which increases the sewage treatment cost. Therefore, we need to propose a full-liquid internal circulation hydrolysis acidification reactor. Utility Model Content
