Background technology

Aeration tank is the structures utilizing activated sludge process to carry out sewage disposal. the mixing condition that certain dwell time of sewage, oxygen amount required for meeting aerobic microbiological and sewage and activated sludge are fully contacted is provided in pond. Aeration tank is mainly made up of cell body, aerating system and three parts of intake-outlet. Chinese patent ZL201510430649.1 provides a kind of multi-functional Treatment of Sludge Aeration tank, the middle part of Aeration tank cell body is provided with the separating screen of one horizontal positioned, cell body is divided into contraminated zone and mud district by separating screen, cell body be respectively arranged at two ends with charging aperture and discharge gate, coagulation device it is sequentially provided with between charging aperture and discharge gate, two stage treatment device, tertiary treatment device and level Four process device, described coagulation device is vertical stirring oar, described two stage treatment device is horizontal stirring paddle, described tertiary treatment device is ventilation circular ring, it is T-shaped sterilizing platform that described level Four processes device, vertical stirring oar and horizontal stirring paddle are arranged on mud district, the compound action of device and separating screen is processed by four sets, Aeration tank is not only completed the Air Exposure to sewage and mud, the initial gross separation operation to mud and sewage and disinfecting action are simultaneously completed, conveniently mud and sewage are processed respectively, optimize the production technology of sewage and mud.

But in the process of Air Exposure, often produce substantial amounts of foam, for above-mentioned foam, typically no it processed or adopts defoamer to process. The main cause bubbled is the existence part chemical component in waste water. This kind of chemical component is cut into little molecule under the hydraulic shear effect that low pressure stream aerating system is stronger, in conjunction with tiny bubble thus forming foam. The existence harm of foam is relatively larger, flows out as taken partial sludge out of, it is easy to makes sludge reflux amount big, increases cost; Reduce oxyty, be unfavorable for the growth etc. of aerobic flora; And the method that the Aeration tank of routine solves foam is to add defoamer, and for most sewage, its internal chemical component is complicated, and the chemical component in sewage is relatively big on the impact of defoamer, and therefore, the result of use of defoamer is also inconspicuous.

This utility model adopts the following technical scheme that for solving the problems referred to above:

A kind of multi-functional Aeration tank, including cell body, described cell body side is provided with water inlet, the described cell body side relative with described water inlet is provided with discharge outlet and mud discharging mouth, described discharge outlet position is higher than described mud discharging mouth, it is characterized in that: described cell body center of inside level is provided with separating screen, described separating screen is arranged above contraminated zone, it it is mud district below described separating screen, it is sequentially provided with stirring paddle along water inlet direction bottom described mud district, breather and froth breaking pipe, described stirring paddle central shaft connects stirring paddle track, described stirring paddle can carry out horizontal reciprocating along described stirring paddle track and move, described froth breaking tube-surface is provided with froth breaking pipe apopore, described froth breaking pipe apopore is for being spaced structure, discharge outlet place described in top, described contraminated zone is provided with every mud plate.

Further, described water inlet connects described mud district.

Further, the shaft of described stirring paddle is made by transparent with machine glass, and the middle part of shaft is provided with fixing light source assembly.

Further, described adopt stainless steel mesh every mud plate, described can form enclosed region every mud plate.

Further, the described sieve number adopted every mud plate is less than described separating screen.

Further, described breather can be strip or annular.

The beneficial effects of the utility model are in that:

(1) provide a kind of multi-functional Aeration tank, be provided with multi-stage treatment units and froth breaking pipe, sewage can be carried out preliminary treatment, have and can eliminate the bubble produced in aeration process;

(2) stirring paddle central shaft connects stirring paddle track, described stirring paddle can carry out horizontal reciprocating along described stirring paddle track and move, stirring area can be increased, reduce stirring paddle number, save cost, matched by transparent shaft and light source assembly in addition, not only ensure that the sewage between mud district and contraminated zone can circulate, ensure that the lighting effect in mud district simultaneously, improve the work efficiency of overall aeration operation;

(3) froth breaking pipe apopore is for being spaced structure, it is possible to improve defoaming effectiveness;

(4) every the sieve number of mud plate employing less than described separating screen, it is possible to filter the silt that particle diameter is less, sand factor in drain pipe is reduced, it is prevented that drain pipe blocks.
