Enhanced denitrification reactor used for advanced denitrification and advanced denitrification method of reactor

Abstract

The invention provides an enhanced denitrification reactor used for advanced denitrification and an advanced denitrification method of the reactor, and belongs to the field of sewage treatment equipment manufacturing. The enhanced denitrification reactor used for advanced denitrification comprises a water inlet pipe, a gas inlet pipe, a pre-stirring reactor and the like; the water inlet pipe and the gas inlet pipe are connected with a shell of the pre-stirring reactor, and a stirring flow-pushing device is arranged in the shell of the pre-stirring reactor and connected with a motor through a rotating shaft; one end of each branch water pipe communicates with the pre-stirring reactor, and the other end is connected to one corresponding influent water distribution system; and two sides of every two adjacent-stage baffling material-hanging plates are connected by one corresponding water blocking plate, each influent water distribution system is arranged in one corresponding water blockingplate, an overflow plate is arranged at the water outlet end in a water flow direction and connected with one end of a nth-stage baffling material-hanging plate, and the water outlet pipe is arrangedat one side of the overflow plate and connected with a reactor outer shell. When the reactor provided by the invention is adopted for inflowing water, advanced denitrification is performed by a fibrous filler of the baffling material-hanging plates, and the reactor adopts a biological denitrification principle, and has the advantages of a good denitrification effect, a short process and a high automation degree.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment manufacturing, and in particular relates to an enhanced denitrification reactor for deep denitrification and a deep denitrification method thereof. Background technique [0002] The regeneration and utilization of sewage is often inseparable from nitrogen and phosphorus removal technology. This is because the traditional secondary biological treatment technology of urban sewage aims to reduce the concentration of carbon-containing organic matter and suspended solids expressed in comprehensive indicators of BOD5 and COD in sewage. Nitrogen and phosphorus can only remove the amount taken up by bacterial cells due to physiological needs. Usually, the removal rate of nitrogen after secondary treatment is only 20% to 40%, the removal rate of phosphorus is only 10% to 30%, and most of nitrogen and phosphorus have not been removed. When recycled sewage with high nitrogen and phosphorus content ...
