Abstract

The utility model discloses an oil separation tank, which is characterized in that: a filter basket is provided between one side of the water inlet on the box and a front clapboard; an upper filter screen and a lower filter screen are installed in the filter basket; a limber hole is provided on the lower part of the front clapboard; a water containing space is formed between the front clapboard and a middle clapboard; a water port is provided on the upper part of the middle clapboard; a space is formed between the middle clapboard and a rear clapboard; a cloth water plate is provided in the space horizontally; an oil outlet is opened on the upper part of one side of the box corresponding to the space; adsorptive separation materials and coal slag are filled in the cavity formed on one side of the water outlet on the middle clapboard and the box and under the cloth water plate; parts of the rear clapboard insert the adsorptive separation materials and coal slag and is not connected with the box bottom.

Description

Oil trap

Affiliated technical field:

The utility model relates to a kind of device that oil-polluted water is purified, and especially can make the oily water separation in the oil-polluted water, removes solid contaminant and impurity in the sewage simultaneously, makes the oil trap of sewage purification.

Background technology:

At present, the main type of known oil trap has parallel flow intercepter, parallel-plate-interceptor, the board-like oil trap of inclination, small-sized oil trap etc., they all are to utilize the nature floating method to carry out the device of oily water separation, promptly in oil trap, because flow velocity reduces, float on the water surface on the relative density oil droplet that particle diameter is bigger less than 1.0, relative density is sunken at the bottom of the pond, to reach the purpose of oily water separation, contamination precipitation greater than 1.0 impurity.The advantage of this class oil trap is, simple structure, be convenient to operational management, deoiling effect is stable; But shortcoming is more: the one, and Chi Tida, floor space is many, and the 2nd, relative density is suspended in the sewage less than 1.0 impurity, and decontamination effect improving is poor, and the 3rd, odor pollution impurity can't remove.

Summary of the invention:

Big in order to overcome existing oil trap pond body, floor space is many and can not remove the deficiency of relative density less than the stink of suspended impurity in 1.0 the sewage and odorant pollutant, the utility model provides a kind of oil trap, this oil trap can not only be with the oily water separation in the oil-polluted water, and relative density in the waste water totally can be reached decomposition, catalysis malodorant less than 1.0 contaminant removal, remove a bad smell.

The technical scheme that its technical problem that solves the utility model adopts is: be equiped with filter basket between one side of the water-in on the casing and preceding dividing plate, filtering net and following filtering net are housed in the filter basket, one limbers is arranged at the bottom of preceding dividing plate, preceding dividing plate and median septum constitute a water space, one outlet pass is arranged at median septum top, median septum and rear bulkhead constitute a space, level is equipped with a water distribution board in this space, to having an oil outlet by spatial casing one upper lateral part, in the cavity that water outlet one side on median septum and the casing constitutes, under the water distribution board, adsorption and separation material and cinder in filling, some inserts rear bulkhead in adsorption and separation material and the cinder, is not connected with bottom half.When oil-polluted water flows into casing from the filter basket that water-in enters in the oil trap, solid contaminant bigger in filter basket is by strainer filtering, and smaller slightly solid-state pollution impurity is filtered at filtering net down again.The effusive sewage of solid contaminant that has been filtering from filter basket, through preceding dividing plate, median septum, water distribution board, inflow is filled with in the lower box of adsorption and separation material and cinder, utilize the nature floating method to carry out oily water separation, float on the water surface on the relative density oil droplet that particle diameter is bigger less than 1.0, when sewage when median septum enters, oil level raises, oil is discharged from oil discharge outlet; And the oil droplet of the less not come-up of particle diameter and pettiness solid impurity all with sewage in water distribution board flows into the casing Lower Half casing that is filled with adsorption and separation material and cinder (because rear bulkhead stops, sewage can't direct current to the exit), methods such as the separation through separating sorbing material and cinder, filtration, absorption, oxidation, precipitation, the clean water that oozes out is discharged from water outlet.

The beneficial effects of the utility model are, can not only be with the oily water separations in the oil-polluted water, and relative density in the waste water totally can be reached decomposition, catalysis malodorant less than 1.0 contaminant removal, remove a bad smell.
