Description

A kind of oil interceptor of idetified separation effect

Technical field

This utility model belongs to technical field of sewage, the oil interceptor of a kind of idetified separation effect.

Background technology

In food and drink waste water, main component is leftover and water, organic with starch based, dietary fiber class, Animal fat class etc. Thing is main component, has that nutritional labeling is high, moisture content high, oils and fats and a feature such as salt content fermentation high, perishable is smelly.Therefore need Before food and drink waste water enters sewer, take pretreatment measure, thus improve the Biochemical Treatment of Sewage Plant.

At present, common oil interceptor is divided into parallel flow intercepter and tilted plate intercepter.When using parallel flow intercepter, useless Water is from the inflow pond, one end in pond, and flows through pond with relatively low horizontal flow velocity (2～5mm/s), and in flow process, density is little Elaioleucite in water rises to the water surface, and density is sunken at the bottom of pond more than the granule foreign of water, and the water other end from pond flows out.In oil removal The water side in pond arranges oil collecting pipe.Oil collecting pipe is typically made with the steel pipe of diameter 200～300, opens along length in the side of tube wall A width of 60 ° or the Chi Kou of 90 ° of arc.Oil collecting pipe can be rotated about axis.During oil extraction oil collecting pipe opened pond directional steering horizontal plane Below to collect oil slick, and oil slick is derived outside pond.In order to enable oil extraction in time and get rid of bed mud, also should arrange in large-scale oil interceptor Frizing mud scraper.The scraper plate translational speed of frizing mud scraper typically should be close with flow velocity in pond, to reduce the impact on current.Make When using tilted plate intercepter, the minimum diameter of the separable oil droplet of this style of oil interceptor is about 60um, the corresponding rate of climb It is about 0.2mm/s.The oily waste water time of staying in tilted plate intercepter is generally no greater than 30min, for parallel flow intercepter 1/4 1/2.The scum silica frost of oil interceptor, based on oil, also contains moisture and some solid impurities.Rely solely on oil droplet and water Density contrast produces and floats and carry out oil, water separation, and the removal efficiency of oil is generally 70%～about 80%, and the water outlet of oil interceptor is still Divide containing a number of oil emulsion and the oil being attached on suspended solid, the most difficult drop to below discharge standard.And absolutely Oils and fats and other impurity in most of food and drink waste waters are the most tiny, therefore traditional process technique is difficult to the method by precipitation Remove this partial contamination thing.

Summary of the invention

Owing to traditional parallel flow intercepter has no ability to remove most impurity and animal oil in waste water, therefore this reality Oil interceptor by novel proposition a kind of idetified separation effect.

The oil interceptor of idetified separation effect of the present utility model, it is characterised in that be made up of five separate ponds, Wherein:

First pond connects with inlet channel, the first pond, the second pond, the 3rd pond, the 4th pond and the 5th water Pond is sequentially communicated by pipe fitting I, pipe fitting II, pipe fitting III and pipe fitting IV respectively, described pipe fitting I, pipe fitting II, pipe fitting III and Pipe fitting IV uses the H type swan neck of upper and lower opening；First pond, the second pond, the 3rd pond and the 4th pond degree of depth are gradually Shoal；The 5th pond degree of depth is the deepest, and inside arranges filtrate, and filtrate is fixed by adjacent metal mesh sheet, and end accesses drain pipe.

The bottom water inlet height of described pipe fitting I, pipe fitting II, pipe fitting III and pipe fitting IV is gradually upper to be moved.

Described pipe fitting V uses tee T, tee T bottom slot.

Described the first pond, the second pond, the 3rd pond and the 4th pond are the most adjacent, use swinging design.

As preferably, the filtrate in the 5th pond arrange before and after two groups, filtrate uses particle diameter at 2-3cm chestnut Carbon Materials；Gold Belonging to mesh sheet uses aperture to be 1cm steel fabric sheet.Chestnut charcoal is the one of activated carbon, the most relatively common, has easily processing, price Cheap, retain the feature of advantages of good adsorption effect.

H type swan neck can effectively stop in pond the top oils and fats in waste water and bottom granule after precipitated and separated miscellaneous Matter enters next pond, the top of H type swan neck and lower all use open design, it is simple to swan neck clear and coherent；Along with The volume in one to the 4th pond is gradually lowered, thus causes in pond after precipitated and separated, top oil layer and bottom waste residue The height of layer changes, for guaranteeing that oils and fats and waste residue do not enter next pond, therefore pipe fitting I, pipe fitting II, pipe fitting III and pipe fitting The bottom water inlet height of IV is gradually upper to be moved.

Food and drink waste water is entered the first pond by introducing pipe, when in pond, the height of waste water is less than pipe fitting I vertical component effect overhead height Before (less than transverse pipe), waste water can precipitate in the first pond.Owing to employing the reason of pipe fitting I, add oil-water separation Efficiency, also increase the treatment effect to waste water, the water inlet of pipe fitting I should be arranged on the position on the lower, centre in the first pond Put, it is ensured that waste water is after precipitated and separated, and oils and fats and the bottom waste residue on its top will not enter into next pond.Second afterwards Pond, the 3rd pond and the 4th pond have employed same design, it is ensured that waste water is obtained in that the abundant time of staying.Directly Enter the 5th pond to waste water, the 5th pond be provided with two groups of filtrates being arranged in parallel, first group of grain filtrate be used for retaining and The particle that in absorption waste water, particle diameter is bigger, second group of grain filtrate is for strengthening a upper process retained and adsorb, purpose It is to remove the particle that in waste water, particle diameter is less, eliminates the float in waste water and animal oil further.

Pipe fitting I, pipe fitting II, pipe fitting III, pipe fitting IV and pipe fitting V all use H type swan neck, this utility model oil interceptor phase Compared with parallel flow intercepter, dirt-removing power significantly improves.This oil interceptor is made up of five ponds, and the-the four pond, the first pond is adopted Designing by swinging, the 5th pond is filtered water reservoir, further enhancing the process of waste water, and feature is that floor space is little, operation Convenient, it is easy to clear and coherent, the unpowered design of omnidistance employing, efficient energy-saving.

Oil interceptor Inlet and outlet water water-quality ratio is relatively:

5th front end, pond refer to through the-the four pond, the first pond but without the 5th pond in that of chestnut charcoal Effluent part.From form, former water behind anterior pond, SS, the COD in water_cr, total dissolved solid, total oil, animals and plants Oil, colourity all have and significantly decline;BOD₅, ammonia nitrogen, anion surfactant, total nitrogen also have certain decline, through No. 5 Behind pond, the indices in water declines further, reaches " sewage enters town sewer water standard " (CJ_343-2010) Sewage enters town sewer water quality A grade standard.Sum up the reason that improves of water quality and have three: during the hydraulic retention of 1, waste water Between substantially increase, precipitate and separate effect is notable.2, after using H type swan neck, hence it is evident that reduce the oils and fats in a upper pond and give up Slag enters next number pond.3, chestnut charcoal adsorbs and has retained the oils and fats of some in waste water, and water quality substantially improves.
