Abstract

The invention provides a plug-in baffled anaerobic tank and a sewage denitrification method based on a biological framework. The anaerobic tank is provided with a plurality of baffles and a plug-flow agitator, and a bottom of the anaerobic tank is provided with a The water inlet pipe is provided with a water outlet weir and a water outlet pipe on the upper part of the anaerobic tank, and a plurality of groups of longitudinal slots matching the size of the baffle plate are arranged on the side wall of the anaerobic tank, and the baffle plate includes a baffle plate A plate frame body and a biological frame installed in the baffle frame body, the biological frame is a hollow porous structure, and the interior is filled with a sulfur autotrophic denitrification biological carrier. The plug-in type baffled anaerobic tank provided by the invention can flexibly adjust the baffled path of sewage, avoid sedimentation and accumulation, improve the reaction and treatment efficiency of sewage, and at the same time facilitate maintenance, which is a significant improvement compared with the prior art.

Description

technical field [0001] The invention belongs to the technical field of wastewater biological treatment, and in particular relates to a biological frame-based plug-in baffled anaerobic tank and a sewage denitrification method. Background technique [0002] The traditional biological nitrogen removal technology is accomplished through ammoniation, nitrification, denitrification and assimilation. The traditional biological denitrification process is mature and the denitrification effect is good, but there are many processes, a large area, the need for additional carbon sources, high energy consumption, and high costs. Sulfur autotrophic denitrification denitrification process uses reduced sulfur as electron donor, NO 3 The autotrophic denitrification process for electron acceptors can effectively remove nitrogen from the water body, and has the advantages of no external carbon source, low operating cost, low sludge output, high efficiency, and simple process. [0003] However...
