Description
Technical field
The utility model belongs to sewage disposal technology technical field, is specially a kind of cascade filtration oil trap.
Background technology
Because municipal sewage plant generally adopts biochemical treatment process, therefore the employing of pretreatment technology should be conducive to generate subsequent treatment process.In food and drink waste water, containing higher vegetable and animals oils, is to improve the effect of biochemical treatment, should arrange except grease pre-treatment facility entering before water drain.At present, the pre-treatment structures of food and drink waste water adopt oil trap more, utilize the difference of specific gravity of oil and water, separate and remove the larger suspension oil of particle in sewage.
Existing common parallel flow intercepter, waste water enters from one end, flow out from the other end, because pool inner water advection speed is very little, relative density be less than 1.0 and the larger oil product impurity of particle diameter at the effect float downward of buoyancy, and, be gathered in the surface in pond, collect oil slick by the oil header and the Oil scraper that are located at pool surface.And in actually operating, in food and drink waste water, contain bone, dish leaf is even scrubbed the impurity such as cloth, starch, albumen, carbohydrate, washing composition and the colloidalmaterial of use, this kind of oil trap cannot effectively be removed organism and the impurity in waste water; In addition, grease in food and drink waste water and the suspended particle overwhelming majority are very tiny, be difficult to pass through gravity separation within the limited residence time, can be described as helpless to this part grease and suspended particle oil trap, oil trap can only be removed part oil slick by gravity separation, and oil trap does not have biochemical degradation function substantially simultaneously.
Summary of the invention
Existing for parallel flow intercepter cannot removal of contamination and there is no the defect of biochemical degradation function, the utility model proposes a kind of cascade filtration oil trap.
Cascade filtration oil trap of the present utility model, comprises the first tank, the second tank and the 3rd tank, it is characterized in that the external water inlet pipe of the first tank, and water inlet pipe mouth place arranges small-sized baffle plate; In the first tank, around water inlet pipe, the enclosing that mesh grille is made is set, the first tank is communicated with the second tank by several pipe fittings I; Along water (flow) direction, at least two dividing plates of vertical setting in the second tank, space is left with the second tank in dividing plate bottom, and as waste water path, the second tank end is connected with the 3rd tank by pipe fitting II; In the 3rd tank, cylinder mould is set, the in-built seedy filtrate of cylinder mould, the 3rd tank end sets out water pipe.
Food and drink waste water imports cascade filtration oil trap from water inlet pipe, and baffle plate has played the effect of energy dissipating, slows down the waste water force and velocity of a current, the enclosing of mesh grille filters for swill, alleviates throw out cleaning difficulty in oil trap, increases removal efficiency, waste water flows into the second tank by the first tank along pipe fitting I, in the second tank inner fluid floating, waste oil is blocked by dividing plate, waste water passes through from the path of dividing plate bottom, finally be left to the 3rd tank by the pipe fitting II of the second tank end, in the 3rd tank, add coarse filtrate, in the time that wastewater streams filters the bed of material, first the suspended particle that particle diameter is larger is trapped within the space of top layer filtrate, thereby make the space between this metafiltration material more and more less, it is more and more higher that retaining power becomes thereupon, result forms the filter membrane that one deck is mainly made up of the solid particulate being trapped gradually, further remove suspended substance and vegetable and animals oils, and can play and improve oil trap water level, increase the effect of the depth of water.
Described pipe fitting I adopts Y-tube, and pipe fitting II adopts swan neck.Pipe fitting I adopts Y-tube.
Further, the second tank terminal position arranges pipe fitting III, and after pipe fitting III adopts, high front low mode accesses in the enclosing of the first tank again, again filters.
As preferably, described coarse filtrate adopts H type improvement polypropylene fibre, tilts to install with the angles of 30 °.H type improvement polypropylene fibre removal CODcr and oily effect are better, and while tilting to install with the angles of 30 °, the residence time of profit on polypropylene material is longer.
As an alternative, described coarse filtrate adopts remodeling flyash, modified fibrous globule filtering material or wherein one or more materials of walnut shell filtering material.Above-mentioned materials all has good removal effect, durable in use, and hydrophilic oleophobic performance is good, and with low cost.
Cascade filtration oil trap of the present utility model, suitable size, each Plant arrangement compactness, convenient operation and management, easy to use, economical; Adopt tertiary effluent groove, in the second tank, add polylith dividing plate, strengthened oil removal efficiency; Pollutants removal rate contrast parallel flow intercepter is significantly increased.
