Further, described air flotation pool device also comprises the first air-dissolving air-float pond and the second air-dissolving air-float pond, and described oil trap, the first air-dissolving air-float pond are also connected described collection mud sump with the second air-dissolving air-float pond.

Further, described homogenizing tank is two.

Compared with prior art, the beneficial effects of the utility model are:

A kind of waste disposal plant described in the utility model, for the design of pitch sewage, carry out multiple-stage treatment by multiple pond to the sewage produced in asphalt production process, SS and COD clearance is high, and the mud in sewage is concentrated to collection mud sump, facilitate postorder process.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model, in the accompanying drawings:

Fig. 1 is the structural representation of a kind of waste disposal plant described in the utility model.

Wherein 1---homogenizing tank; 2---oil trap;

3---equalizing tank; 4---hydrolysis acidification pool;

5---anoxic pond; 6---Aerobic Pond;

7---settling tank.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.

A kind of waste disposal plant described in the utility model, comprises the homogenizing tank 1, oil trap 2, equalizing tank 3, air flotation pool device, hydrolysis acidification pool 4, anoxic pond 5, Aerobic Pond 6, the settling tank 7 that connect successively.

Oil trap 2 utilizes suspended substance in waste water different with the proportion of water, and reach the object of both separation.Waste water flows into from one end of oil trap 2, flows through pond body with less flow velocity, and in flow process, the elaioleucite that density is less than water rises to the water surface, and water flows out from the other end of oil trap 2.Oil header is set on the top of oil trap 2, collects oil slick and derived oil trap 2.

Equalizing tank 3 can carry out preliminary sedimentation, separation; And regulating water quality, be that water quality can be balanced, also have adjusted the speed of current simultaneously.

Air flotation pool device comprises air-dissolving air-float pond, cavitation air flotation pond 10, first 11 and the second air-dissolving air-float pond 12.Cavitation air flotation pond 10 by aerator by air transfer under water, in bubble floating process, microbubble can be attached on suspended substance, thus take suspended solid to the water surface and remove, it can remove the grease in water, solid suspension material, BOD and COD, and be by solid sludges automatically and remove from waste water continuously.

Air-dissolving air-float pond delivers in air vessel by air compressor by air, and air is brought into dissolving by fluidic device, is forced to be dissolved in water under 0.35MPa pressure, forms dissolved air water, deliver in air flotation slot.Then when release suddenly, the air be dissolved in water is separated out, form a large amount of microbubble groups, with pumping come and suspended substance in the sewage flocculated after dosing fully contact, and be adsorbed in the suspended substance of wadding a quilt with cotton and having collected in slow uphill process, its density is declined and floating to the water surface, reaches the object removing SS and COD.

Second air-dissolving air-float pond 12 mainly uses a large amount of microbubble to flutter to catch absorption fine particle gluing thing to make it to float, and reaches the object of solid-liquid separation.

Waste water through the second air-dissolving air-float pond 12 enters hydrolysis acidification pool 4, hydrolysis acidification pool 4 is dissolved organic matter by insoluble hydrolysis of organic matter under a large amount of hydrolytic bacteria, the effect of acidifying bacterium, the macromolecular substance of difficult for biological degradation is converted into the process of the small-molecule substance of readily biodegradable, thus improve the biodegradability of waste water, for subsequent disposal establishes good basis.

The biochemical sludge of oily sludge and settling tank 7 generation that oil trap 2, cavitation air flotation pond, the first air-dissolving air-float pond 12, air-dissolving air-float pond 11, second and settling tank 7 are all connected the generation of collection air-dissolving air-float pond 12, mud sump 13, first air-dissolving air-float pond 11, second is concentrated in collection mud sump 13 and is for further processing.

Macromole organic granular, for coordinating Aerobic Pond 6 denitrogenation dephosphorizing, is resolved into small molecules organic granular by anoxic pond 5, can improve the biodegradability of waste water, is generally used for the pre-treatment of Aerobic Pond 6.

The effect of Aerobic Pond 6 allows active sludge carry out aerobic repiration, further organic substance decomposing become inorganics.

Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
