Abstract
The invention discloses a dissolved air flotation device of a mid-set type hexagonal reaction tank and relates to solid-liquid separation in the field of sewage treatment. The device comprises a tank body, the tank body is divided into a left contact chamber and a right reaction tank, the bottom of the left contact chamber is provided with a backflow water inlet, the reaction tank comprises several spliced orthohexagonal tanks, the orthohexagonal tank in the center of the reaction tank is a triple reaction tank, the triple reaction tank comprises three spliced diamond-shaped tanks, and a stirrer is arranged in each one of the diamond-shaped tanks. The dissolved air flotation device has a simple structure, a low making cost and high stability, is not easily damaged and improves deposition efficiency.
Description
Technical field
The present invention relates to the solid-liquid separation of sewage treatment area, particularly relate to air-dissolving air-float.
Background technology
Air-dissolving air-float (DAF) is pneumatically supported one, it utilizes the characteristic of water different solubility at various pressures, the water of the most pending (or after processing) is carried out pressurization aerating, increase the Underwater sound field of water, be passed through in the water adding coagulant, discharge in the case of normal pressure, air separates out and forms minute bubbles, stick to, on impurity wadding grain, cause wadding grain global density to rise less than water, so that solid-liquid separation.
Air-dissolving air-float is typically made up of dissolving, water pump, dissolved air release, cell body etc., traditional air-dissolving air-float is generally square or rectangle (also have a few part conglobate without doing of triple response groove), triple response groove is generally square or rectangle, is positioned at the front end of air-dissolving air-float.Its structure floor space is relatively big, and medicament diffusion is uneven, and it is longer that alumen ustum forms the time, and deposition efficiency is poor, and cost of manufacture is the highest, structural instability.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of simple in construction, cost of manufacture is low, and stability is high, not cracky, improves the air-dissolving air-float putting hexagon reactive tank in deposition efficiency.
nullFor realizing the object of the invention，Provide techniques below scheme: in put the air-dissolving air-float of hexagon reactive tank，Including cell body，Cell body is divided into left contact room and two regions of right side reactive tank，Bottom, left contact room is provided with recirculation water import，Reactive tank bottom, right side is provided with outlet，Nearly top is provided with slag-drip opening，It is characterized in that described reactive tank is spliced to form by several regular hexagon cell bodies，The regular hexagon cell body being positioned at reactive tank center is triple response groove，Described triple response groove is spliced by 3 prismatic cell bodies，It is provided with agitating device in each prismatic cell body，Prismatic cell body is all separated into three impartial parallelogram regions，Triple response groove top is provided with water inlet，Described right side reaction tank bottom is placed with a circle collecting conduit around triple response groove，Described collecting conduit includes a supervisor and connects with supervisor and vertically disposed be in charge of，Described being in charge of offers gully-hole，Gully-hole Surface coating has stainless steel filter screen.
As preferably, contact chamber is regular hexagon.
As preferably, regular hexagon cell body is 1:15 with the ratio of cell body.
The method have the benefit that the present invention is positioned at the center of air-dissolving air-float by arranging triple response groove, have an advantage in that:
1, each cell body is all the diamond structure of standard, it is possible to fabulous utilizes bulk, and comparatively speaking, such structure is formed into the structure that fixed volume container consumptive material is minimum, and it has again fabulous stability, not cracky simultaneously.
2, regular hexagon structure makes reactive tank cell body and extraneous contact surface in open sector, the more conducively diffusion of medicament, shortens the time that alumen ustum is formed so that precipitate highly efficient fast.
3, generally speaking, the response time of every kind of medicament and sewage is 3-4 minute, and the time needed for alumen ustum precipitation is 45-60 minute, therebetween ratio 1:15, and the ratio between the volume of each cell body of triple response groove and sedimentation tank cell body (removing a cell body as contact chamber) is the most also 1:15, thus without spending the too many time go calculation and build sedimentation tank cell body, only the appearance in pond, center need to be simply copied just.
4, under regular hexagon structure makes same homalographic, center is shorter to the distance of periphery, it is easier to builds the bucket bottom sedimentation tank, the most more saves material, saved cost of manufacture.
