Abstract

The invention provides a plugboard type baffled anaerobic tank based on a biological framework and a sewage denitrification method.The plugboard type baffled anaerobic tank is internally provided with a plurality of baffle plates and a plug-flow stirrer, the bottom of the anaerobic tank is provided with a water inlet pipe, the upper portion of the anaerobic tank is provided with an effluent weir and a water outlet pipe, and the upper portion of the effluent weir is provided with a water inlet pipe; a plurality of groups of longitudinal slots matched with the baffle plates in size are formed in the side wall of the anaerobic tank, each baffle plate comprises a baffle plate frame body and a biological frame mounted in the baffle plate frame body, and the biological frame is of a hollow porous structure and is filled with a sulfur autotrophic denitrification biological carrier. The plugboard type baffling anaerobic tank provided by the invention can flexibly adjust the baffling path of sewage, avoids deposition and accumulation, improves the reaction treatment efficiency of the sewage, is convenient to maintain, and has remarkable progress 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 insert-type baffle anaerobic pool and a sewage denitrification method. Background technique [0002] The traditional biological denitrification technology is accomplished through ammonification, nitrification, denitrification and assimilation. The traditional biological denitrification process is mature, and the denitrification effect is good, but there are many processes, large land occupation, additional carbon source, high energy consumption, and high cost. Sulfur autotrophic denitrification process uses reduced sulfur as electron donor, NO 3 The autotrophic denitrification process for the electron acceptor can effectively remove nitrogen in the water body, and has the advantages of no need for additional carbon source, low operating cost, low sludge output, high efficiency, and simple process. [0003] However, wh...
