Abstract
The utility model relates to a wastewater treatment device, in particular to a novel oil-extracting waste water filtering tank. The novel oil-extracting waste water filtering tank comprises a tank body, wherein a water inlet is formed at the upper end of the tank body; a water outlet is formed at the lower end of the tank body; a bearing layer is positioned at the inner lower part of the tank body; three filtering material layers are arranged above the bearing layer; and the upper filtering material layer is a fiber ball-type filtering material layer, the middle filtering material layer is a husk-type filtering material layer, and the lower filtering material layer is an ore-type filtering material layer. Filtering materials of the oil-extracting waste water filtering tank are good in regeneration, high in filtering capacity, and long in replacement cycle.
Description
Technical field
The utility model relates to sewage-treatment plant, is specifically related to a kind of novel oil production sewage water filtration tank.
Background technology
Oil extraction-generated waste water after treatment, re-injection is to geology, replenishes stratum energy, improves oil recovery.Important treatment facility is the oil extraction-generated waste water filtering tank in the oil extraction-generated waste water processing procedure, oil extraction-generated waste water filtering tank filtrate in usefulness is the quartz sand filter media layer composition of different-grain diameter at present, filtrate is single, deoiling function is poor, and easily through after flushing, filtering, the filter effect variation serious mixed layer appears,, filtrate is short service time, affects operating efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the novel oil production sewage water filtration tank that a kind of media regeneration performance is good, filter capacity is high, the filter material replacement cycle is long is provided.
The technical solution of the utility model is:
Novel oil production sewage water filtration tank, comprise tank body, the tank body upper end arranges water inlet, and the tank body lower end sets out the mouth of a river, and supporting layer is positioned at the tank body bottom, the supporting layer top is filter material layer, it is characterized in that, filter material layer divides three layers, and the upper strata is the ball filter material layer of fiber, the middle level is shell class filter material layer, and lower floor is ore class filter material layer.
Described supporting layer below arranges collector pipe.
Described collector pipe is the wrapping wire welded pipe.
The beneficial effects of the utility model are: three-layer filter layer from top to bottom proportion increases successively, the original state of filter material layer can be not destroyed because repeatedly washing, repeatedly filtering, all the time near desirable filtering ponds state, good filtration effect, the media regeneration performance is good, and the filter material replacement cycle reaches 3 years, adopts the wrapping wire welded pipe to collect filtered water, the decrease resistance to water-flow improves the rate of filtration.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The ball filter material layer 3 shell class filter material layers of 1 tank body, 2 fibers 4 ore class filter material layers 5 supporting layers 6 wrapping wire welded pipes 7 water inlets 8 delivery ports.
The specific embodiment
Novel oil production sewage water filtration tank, comprise tank body 1, tank body 1 upper end arranges water inlet 7, and tank body 1 lower end sets out the mouth of a river 8, supporting layer 5 is positioned at tank body 1 bottom, supporting layer 5 tops are filter material layers, and filter material layer divides three layers, and the upper strata is the ball filter material layer 2 of fiber, the middle level is shell class filter material layer 3, lower floor is ore class filter material layer 4, and supporting layer 5 belows arrange collector pipe, and collector pipe is wrapping wire welded pipe 6.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
