Description

air floatation equipment for landfill leachate treatment

Technical Field

The utility model relates to a sewage treatment technical field specifically is kinds of air supporting equipment that are used for landfill leachate to handle.

Background

The leachate in the garbage transfer station has -degree, complex and variable components, the concentration of pollutants can be different by several orders of magnitude, and the leachate is characterized by high concentration of pollutants, large water quality change, strong odor, yellow brown or grey brown, and very high animal and vegetable oil content in water.

The conventional air floatation equipment is mainly used for treating domestic sewage and process sewage, no special air floatation equipment for removing oil and suspended matters from leachate of a garbage transfer station exists at present, the existing air floatation equipment is limited in volume, the depth of a scum collecting tank is insufficient, foams overflow to a water outlet tank when foams are too much, in addition, the effluent still contains a large amount of suspended matters due to unreasonable design of a water outlet form, and the purification effect is not obvious.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing kinds of technical scheme that can solve above-mentioned problem.

be used for landfill leachate to handle air supporting equipment, the water tank comprises a water tank, the dissolved air pump, side is equipped with the dashpot in the water tank, the top that is located the top water tank of dashpot is equipped with the water inlet, the delivery outlet of dissolved air pump is connected with the releaser, the interior bottom of dashpot is located to the releaser, the outside of water tank is equipped with out the basin with the top of the relative side of dashpot, the side that goes out the basin and be close to the dashpot is equipped with the overflow board, the bottom of going out the basin is equipped with the delivery port, be located and be equipped with the dross collecting vat on the inboard water tank top surface of overflow board, the interior top surface of water tank is located the notch department of dross collecting vat and installs the sediment machine of scraping, the outer bottom of dross collecting vat is equipped with the baffle, the.

, a water inlet pipe extending to the bottom of the buffer tank is installed in the water inlet.

And , connecting the bottom of the water outlet groove with a return pipe communicated with the input port of the dissolved air pump.

And , connecting a demulsifier input pipe communicated to the bottom in the buffer tank on the water tank adjacent to the water inlet.

And , the depth of the scum collecting tank is 1/2 of the depth of the water tank.

And , arranging an emptying port at the bottom of the water tank outside the buffer tank.

Compared with the prior art, the utility model discloses the beneficial effect who gains does: the utility model has novel structure, increases the depth of the scum collecting groove, and avoids the problem that the scum foam can not be discharged to overflow to the water outlet groove in time because the content of suspended matters in the garbage percolate is too high and the scum is too much in the aeration process; and the baffle is additionally arranged at the outer bottom of the scum collecting tank, so that the effluent flows into the effluent tank through the overflow plate after being rectified by the baffle, the retention time of the sewage in the air floatation equipment is prolonged, and a more sufficient purification effect is obtained.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only the embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without inventive labor.
