Abstract

The utility model provides a sewage deodorizing device that is used for deodorizing sewage from buried type ascending counterflow anaerobic filter tank, comprising a buried type ascending counterflow anaerobic filter tank, a lifting pump system, a deodorizing tower and an underflow artificial marsh. The sewage deodorizing device is characterized in that the buried type ascending counterflow anaerobic filter tank is wholly buried underground; the underflow artificial marsh is arranged on the upper surface of a cover plate of the filter tank; the underflow artificial marsh and the filter tank are superposed with each other so as to form a stereoscopic structure. After the contaminations such as COD, BOD and SS in the sewage are removed by the buried type ascending counterflow anaerobic filter tank; the filtered water is sent to the top end of the deodorizing tower by the lifting pump and is sprayed downwards; the air is lifted upwards from the air inlet at the bottom of the deodorizing tower; the air and the sewage form convection so that the sewage is deodorized. The deodorized sewage automatically flows to the underflow artificial marsh so that N contamination and P contamination are removed; and finally the deodorized sewage is discharged from the water outlet of the underflow artificial marsh. The sewage deodorizing device has the advantages of improving the concentration of the oxygen dissolved in the sewage and eliminating the stench pollution of the sewage.

Description

The sewage deodorization device

Affiliated technical field

The utility model relates to a kind of sewage deodorization treatment unit, specifically refers to it is a kind of sewage deodorization device that carries out buried raising and adverse current anaerobic filter water outlet the deodorization processing.

Background technology

By buried raising and adverse current anaerobic filter; The lift pump system, (patent No.: ZL200820053407.0), the major function of buried raising and adverse current anaerobic filter is to remove COD in the patented technology " tridimensional oligodynamic wastewater treatment facilities " that underflow type artificial wet land is formed; BOD; SS pollutent, the major function of underflow type artificial wet land then are to remove N, P and other pollutents.This technology has the microkinetic operation, and floor space is few, and processing efficiency is high, convenient for maintenance management, and can remove COD simultaneously, BOD, SS, N, the advantage of P pollutent.But should technology when actual motion, foul smell is distributed in buried raising and adverse current anaerobic filter water outlet, directly gets into underflow type artificial wet land, and peripheral personnel and environment are polluted.

Summary of the invention

The purpose of the utility model is, in tridimensional oligodynamic wastewater treatment facilities, do not increase under the prerequisite of any power machine, provides a kind of the sewage deodorization device that deodorization is handled is carried out in buried raising and adverse current anaerobic filter water outlet.

In order to achieve the above object, the technical scheme of the utility model is following design:

A kind of sewage deodorization device of buried raising and adverse current anaerobic filter water outlet deodorization; Comprise buried raising and adverse current anaerobic filter, lift pump system, deodorization tower; Underflow type artificial wet land; It is characterized in that: buried raising and adverse current anaerobic filter integral body is embedded in underground, and underflow type artificial wet land is arranged on above the cover plate of buried raising and adverse current anaerobic filter, and the two is overlapped into three-dimensional arrangement.Sewage is removed COD through buried raising and adverse current anaerobic filter, and BOD is behind the SS pollutent; Riser flows automatically to pump well from the water side, and through lift pump, water pipe and valve are delivered to by body of the tower again; Shower nozzle, the top of the deodorization tower that filler and blast inlet are formed sprays downwards, and air is pulled out to rise upwards from the tower bottom blast inlet to flow; Air and sewage form convection current, and the sewage after the deodorization flows automatically to the water distributor of underflow type artificial wet land, through matrix fill; Water loving plant is removed N and P pollutent, and header and the water outlet from underflow type artificial wet land outwards discharges at last.

The utlity model has following advantage:

1, sewage drops in and is ground into the tiny globule on the inner-tower filling material from deodorization cat head spray, fully contacts with air again, can improve the concentration of dissolved oxygen in the sewage greatly, and then improves the clearance of pollutent in the sewage.

2, get into underflow type artificial wet land after the sewage deodorization again, eliminated the pollution of foul smell to surrounding enviroment, improved the operational condition of tridimensional oligodynamic wastewater treatment facilities operation.
