Abstract

The invention relates to a combined device for oily sewage treatment and belongs to the field of sewage treatment of oil fields. In order to solve the problem that the existing sewage treatment device is low in utilization ratio and sewage cannot be recycled, the invention provides a combined device capable of recycling. The combined device comprises a grating, an adjusting oil separator, an advection oil separator, a floatation device and an active carbon adsorption filter which are sequentially connected by virtue of a pipeline. The adjusting oil separator and the advection oil separator are externally connected with an oil collecting pond, respectively, the flotation device is externally connected with a dosing device, and a deslagging outlet is externally connected with a sludge drying pond. The combined device can be used for recycling sewage, so that no novel impurities in the treatment process are generated, the sewage production volume is reduced, and meanwhile, the device is simple and low in cost.

Description

A kind of oily water treatment combination unit
Technical field
The invention belongs to field of oilfield sewage treatment.
Background technology
Oilfield sewage mainly comprises the oily(waste)water that other type in water (having another name called oil field extracted water), drilling waste water and station deviate from by crude oil, because oilfield sewage kind is many, the reasons such as stratum difference and drilling technology, each disposing polluted water in oil station water quality difference is large, and this is that the process of oilfield sewage brings difficulty.China's onshore petroleum industry is mostly in some arid areas, water resources critical shortage, the recycling of sewage can not only Gu Jieyue enterprise cost, meet environmental requirement again, the repeating utilization factor of American industry sewage reaches 1700%, namely reuses 17 times, and the utilization ratio of China's Huanghe valley industrial sewage is also less than 30%, the sewage produced in oil recovery process is turned waste into wealth, carries out secondary after process, repeatedly apply, be of great practical significance.
Summary of the invention
The object of this invention is to provide a kind of oily water treatment combination unit, be intended to solve sewage disposal utilization ratio low, can not the problem of recycle.
The present invention is achieved by the following technical programs: a kind of oily water treatment combination unit, comprise be connected successively by pipeline barrier, regulate oil trap, advection oil separation tank, air-floating apparatus and charcoal absorption strainer, described adjustment oil trap and parallel flow intercepter external oil sump respectively, described air-floating apparatus is circumscribed with chemicals dosing plant, and deslagging exports external sludge drying pond.
Described adjustment oil trap comprises multiple oil trap be connected in series successively.
Described parallel flow intercepter comprises multiple oil trap be connected in series successively.
Described air-floating apparatus is that more than 1 or 1 air-floating apparatus is composed in series.
The external back-washing equipment of described charcoal absorption strainer, backwash water outlet access regulates oil trap.
The present invention has following beneficial effect:
Can carry out repeatedly circular treatment to oily(waste)water, improve sewage treating efficiency, decrease sewage generation, not produce new impurity in treating processes, the equipment simultaneously adopted is simple, with low cost.
Accompanying drawing explanation
Below in conjunction with specific embodiment, the present invention will be further described.
Fig. 1 is the schematic flow sheet of oily water treatment combination unit provided by the invention.
In figure: 1. barrier, 2. regulate oil trap, 3. advection oil separation tank, 4. oil sump, 5. air-floating apparatus, 6. charcoal absorption filtration unit, 7. chemicals dosing plant, 8. sludge drying pond.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further.
Embodiment: as shown in the figure, oily(waste)water combined treatment device flow process is as follows: oilfield sewage as shown by arrows, enters barrier 1, except comparatively bigger material in decontaminated water, prevents blocking pipe, protects the normal operation of follow-up sewage disposal device; After barrier 1 processes, sewage enters and regulates oil trap 2, oil trap 2 is regulated to comprise the oil trap of multiple series connection, be preferably two, water is introduced into first oil trap, utilize gravitational separation process to carry out oil removal process, oil slick enters oil sump 4 by oil trap, along with liquid level constantly raises, oily(waste)water overflow to the second oil sump is separated further, and oil slick enters oil sump 4; After process, sewage enters parallel flow intercepter 3, and parallel flow intercepter 3 comprises the oil trap of multiple series connection, is preferably two, and this parallel flow intercepter 3 fouling is simple, the oil droplet that separable removal diameter is greater than 150 μm, and its processing mode is similar to adjustment oil trap 2; Oily(waste)water carries out after oily water separation through oil trap, still containing fine oil slick and oil in water emulsion, therefore flotation process removing is adopted, before sewage enters air-floating apparatus 5, by chemicals dosing plant 7 dosing coagulant, by the purification further such as oil-in-water, COD, its scum silica frost produced enters sludge drying pond 8, carries out mummification, burning disposal; After the effect of air-floating apparatus 5, sewage enters charcoal absorption strainer 6, carry out deep purifying, charcoal absorption strainer 6 is circumscribed with back-washing equipment, regularly it is cleared up, backwash water is entered by pipeline and regulates oil trap 2 to process again, and in figure, all oily(waste)waters are entered subordinate's treatment unit process by upper stage arrangement and all realized by the effect of pump.
oily water treatment combination unit described in the embodiment of the present invention, can carry out circular treatment to sewage, ensures not produce new impurity in treating processes, and decrease sewage generation, the equipment simultaneously adopted is simple, with low cost.
above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
