Abstract
The utility model provides an industrial park sewage treatment device and aims to overcome the defects of individually using an A<2>/O process or a biological aerated filter (BAF) in the conventional industrial park sewage treatment process. The device comprises a high level water tank, an A<2>/O reactor, the BAF and a settling pond, wherein the high level water tank is connected with the bottom of an anaerobic pond through a pipeline; the top of an aerobic pond is connected with the settling pond through a pipeline; the upper part of the settling pond is connected with the BAF through a pipeline; aerators of which the aeration gas is supplied by an air compressor are arranged in the aerobic pond and the BAF; a nitrification liquid returning pipe and a nitrification liquid returning pump are arranged between the aerobic pond and an anoxic pond; and the bottom of the settling pond is connected with the bottom of the anaerobic pond through a sludge returning pipe which is provided with a sludge returning pump. The defects of high blockage possibility due to independent usage of the BAF and instable nitrogen content in discharged water due to independent usage of the A<2>/O process are overcome by the industrial park sewage treatment device, and the industrial park sewage treatment device is high in impact load resistance and has good denitrification and dephosphorization effects.
Description
Technical field
The utility model relates to a kind of sewage disposal device.
Background technology
At present, the A that adopt when handling industrial park sewage more
2/ O technology and biological aerated filter process.
A
2/ O technology is the mainstream technology of bio-denitrifying sewage dephosphorization, and it is on A/O technology basis, to have increased an oxygen-starved area, and system is made up of anaerobic pond, anoxic pond and three functional zone of Aerobic Pond.Get into anaerobic pond through the waste water of preliminary sedimentation tank post precipitation and returned sluge, the circulation nitrification liquid by Aerobic Pond with being pumped into anoxic pond.Carry out the release of phosphorus at anaerobic pond, carry out denitrification denitrogenation in anoxic pond, carry out nitrated and picked-up phosphorus at Aerobic Pond, water outlet is discharged through the second pond post precipitation.The flow process of this technology is comparatively simple, and working cost is lower, and has the effect of synchronous denitrification dephosphorizing, is that sewage treatment area is used more technology, but has the unsettled shortcoming of water outlet nitrogen content.
BAF (Biological aerated filter, be called for short BAF) technology comes across Europe in the seventies and eighties in 20th century, and it is on the basis of bio-contact oxidation, to introduce the thought of feedwater rapid filter and a kind of aerobic waste water treatment process that produces.This technology collection filters, bio-oxidation is three-in-one and biological absorption, can play the effect of second pond, sand filter and common aeration tank simultaneously, but has the problem of BAF strainer easy blocking.
Because the sewage situation in the industrial park is complicated, uses above treatment process effectively not handle sewage separately.
Summary of the invention
The purpose of the utility model is to adopt A in the sewage treatment process of existing industrial park separately in order to overcome
2The existing defective of/O technology or BAF provides a kind of industrial park waste disposal plant.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of industrial park waste disposal plant comprises elevated tank, A
2/ O reactor drum, BAF pond and settling tank, A
2/ O reactor drum is made up of anaerobic pond, anoxic pond and three functional zone of Aerobic Pond; Elevated tank is connected with the bottom of anaerobic pond through pipeline; The Aerobic Pond top is connected with settling tank through pipeline; Settling tank top is connected with the BAF pond through pipeline; Be respectively arranged with the aeration head that aeration is provided by air in Aerobic Pond and the BAF pond, nitrification liquid return line and nitrification liquid reflux pump are housed between Aerobic Pond and the anoxic pond, the settling tank bottom is connected with the bottom of anaerobic pond through the mud return line that sludge reflux pump is housed.
Utilize lift pump that sewage is risen to elevated tank, sewage is at A
2In/O the reactor drum with the mud thorough mixing; Muddy water mixed solution overflow gradually gets into the settling tank deposition; Mud-water separation is passed through the water outlet of settling tank top to the BAF pond; A part of mud of settling tank is back in the anaerobic pond through sludge reflux pump, and another part is discharged from the shore pipe of settling tank bottom, and the nitrification liquid in the Aerobic Pond is back to anoxic pond.
The utility model sewage treatment facility adopts " A
2/ O technology and BAF " method that combines, overcome the problem of independent use BAF strainer easy blocking and used A separately
2The unsettled shortcoming of/O technology water outlet nitrogen content has good capacity of resisting impact load and denitrogenation dephosphorizing effect.
