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.
As shown in Figure 1, a kind of asphalt production oil-contained waste water treatment device 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, settling tank 7, intermediate pool 8, acidication tower 9 and the BAF device 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 12, air-dissolving air-float pond 11, second, cavitation air flotation pond 10, first and the 3rd air-dissolving air-float pond 13.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 3rd air-dissolving air-float pond 13 is by 1/3 pond, 2/3 pond 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.
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.
Acidication tower 9 is also be 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 small-molecule substance of readily biodegradable.
BAF device comprises BAF distribution reservoir 14 and BAF pond 15, BAF distribution reservoir 14 is one, and BAF pond 15 is two, and BAF distribution reservoir 14 connects the bottom in BAF pond 15.
BAF (biological aerated filter) is called for short BAF, its principle is with microbial film on the filler in reactor, microorganism in microbial film has oxygenolysis, filler and biomembranous absorption detention effect and the food chain classification predation formed along water (flow) direction, and the denitrification of the inner microenvironment of microbial film and anaerobism section.
BAF pond 15 processed waste water enters clean water basin 16 and discharges.
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.
