Multifunctional sludge nitrification biological filter tower

Abstract

The invention discloses a multifunctional sludge nitrification biological filter tower. A denitrification area is arranged at the lower part of a tower body; a nitrification area is arranged at the upper part of the tower body; the denitrification area is isolated from the nitrification area through a three-phase separator; a water inlet is formed in the bottom of the tower body and is communicated with a water distribution pipe in the tower body; a water outlet is formed in the top of the tower body and is communicated with a water collecting tank at the top of the tower body; the top of a gas collecting box of the three-phase separator is directly communicated with an exhaust port in the top end of the tower body through a methane rising pipe; an aeration device is arranged at the lower part of the nitrification area. According to the multifunctional sludge nitrification biological filter tower, denitrification process equipment and nitrification process equipment in sludge treatment are combined into a whole, so that the occupied area and the manufacturing materials are greatly reduced; the investment and the using cost are reduced. The process line is reasonable; another piece of equipment is not required to be arranged for flow pushing and stirring; the operating cost is low; the treatment effect is good.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a multifunctional sludge nitrification biological filter tower for sewage treatment. Background technique [0002] In water treatment processes such as industrial sewage, urban sewage, food wastewater, chemical sewage and landfill leachate, denitrification and nitrification processes are usually used, and sludge nitrifying bacteria and aerobic bacteria are used to treat COD, BOD, ammonia nitrogen and total nitrogen in sewage. and total phosphorus removal. The existing denitrification and nitrification equipment are independent, and need to set up push flow and mixing equipment, which occupy a large area, consume a lot of energy, and have high investment and operating costs. At present, there is also improved equipment that combines the two processes into one, but it is only a relatively simple combination and cannot handle the connection of the two processes wel...

Problems solved by technology

The existing denitrification and nitrification equipment are independent, and need to set up push flow and mixing equipment, which occupies a large area, consumes a lot of energy for operation, and has high investment and operation costs

At present, there is also improved equipment that combines the two processes into one, but it is only a relatively simple combination and cannot handle the connection of the two processes well.
