Abstract

The invention discloses a spiral-flow type reflux hydrolytic acidification reactor and belongs to the field of sewage treatment reactors. The spiral-flow type reflux hydrolytic acidification reactor comprises a reactor body and is characterized in that an effluent weir is connected to the top of the reactor body, a water outlet pipe is connected to the effluent weir, a retaining ring is connectedinto the upper end of the reactor body, a sludge discharge pipe is arranged at the bottom of the reactor body, a sludge outlet pipe is connected to the sludge discharge pipe, a PE baffle plate component is further arranged inside the upper end of the reactor body, the PE baffle plate component is located above the retaining ring, and a first PE water distribution pipe and a second water distribution pipe are arranged at the bottom of the reactor body. The spiral-flow type reflux hydrolytic acidification reactor has the advantages that sewage is sufficiently mixed with sludge in the reactor body, rotation-ascending spiral flow is formed, reaction efficiency is increased, sludge concentration in the reactor is guaranteed, the sewage is separated from treated sewage, and the sludge is retained in the efficient hydrolytic acidification reactor.

Description

technical field [0001] The invention relates to the technical field of sewage treatment reactors, in particular to a cyclone type reflux hydrolysis acidification reactor. Background technique [0002] Hydrolytic acidification is the first part of the anaerobic reaction, mainly using anaerobic and concurrently trophic microorganisms to decompose macromolecular substances in wastewater, and the existing hydrolytic acidification reactors are mainly divided into packed type and upflow type hydrolysis acidification reactors , but in the process of actual operation, the existence of these two hydrolytic acidification reactors has low operating efficiency, insufficient mixing of mud and water, and muddy water. [0003] Therefore, there is an urgent need to develop a method that can not only ensure that the sewage in the reactor is fully mixed with the sludge in the reactor, thereby improving the removal efficiency of microorganisms on pollutants in the sewage, but also ensuring the...
