Abstract
The utility model relates to a full-automatic dissolved air flotation device. The full-automatic dissolved air flotation device comprises an air floatation box body, an adjustment barrage, a water inlet, a water outlet, a pollution outlet, a dissolved air tank, a mud scraper and a residue collection groove, wherein the mud scraper is arranged on the upper portion of the air floatation box body. The dissolved air flotation device further comprises a dissolved air pump and a water-receiving water-removing system, wherein the dissolved air pump is arranged on the outer side of the lower portion of the air floatation box body, one end of the dissolved air pump is connected with the dissolved air tank, the other end of the dissolved air pump is connected with a return pipe and communicated with the inside of the air floatation box body, and the water-receiving water-removing system is arranged on the lower portion of the air floatation box body and is connected with the adjustment barrage. The full-automatic dissolved air flotation device is modified on the foundation of a traditional dissolved air flotation device. According to the full-automatic dissolved air flotation device, the dissolved air pump is used to replace a traditional booster pump, an air compressor, an ejector, a high-pressure dissolved air tank, an air-water mixer, a release head and the like. The problems of complex system, unstable operation and bubbling of big air bubbles in a traditional device are resolved. The return pipe is scientifically arranged inside the device, a water-receiving air-removing system is additionally arranged, and therefore outflowing water is prevented from carry air bubbles to affect further treatment.
Description
Technical field
The utility model relates to the treatment unit of a kind of municipal effluent and trade effluent, relates in particular to a kind of full-automatic dissolved air flotation device.
Background technology
The difference of pressure of living in when air-dissolving air-float is separated out from water according to bubble can be divided into two kinds of vacuum type air supporting method and pressure air-dissolving air-float methods.The former utilizes and vacuumizes, and at normal pressure or dissolved under pressure air, under negative pressure, discharges microbubble then, and air feed is floating to be used; The latter is under the pressurization situation, makes force air soluble in water, and decompression suddenly discharges dissolved gases from water then, adheres to wadding grain, come-up together with the microbubble form.
The vacuum type air flotation pool, though energy consumption is low, the adhesion of bubble formation and bubble and wadding grain is more stable; But the bubble burst size is restricted; And all facilities parts all will be sealed in the air flotation pool; The complex structure of air flotation pool; Only be applicable to and handle the not high waste water (not being higher than 300mg/l) of Pollutant levels, so practical application is few.
Pressure air-dissolving air-float method basic procedure has three kinds of whole process dissolved air flotation, part dissolved air flotation and partial reflux dissolved air flotations.A, whole process dissolved air flotation dissolve large-minded, and all waste water is through pressure pump, and required pressure pump and dissolving are all big than other two kinds of flow processs, and investment and running power consumption are bigger.B, part dissolved air flotation are to get the pressurization of part waste water and dissolve gas, and all the other waste water directly get into air flotation pool and in air flotation pool, mix with molten gas waste water, and are lower than the power consumption of whole process dissolved air flotation.C, partial reflux dissolved air flotation are that the water of getting after a part is handled refluxes; Recirculation water pressurizes and dissolves gas; Decompression back gets into air flotation pool, mixes and air supporting partial reflux pressurized dissolved air flotation save energy with oily(waste)water from flocculation basin; Can make full use of flotation (coagulation) agent, treatment effect is superior to full pressurized dissolved air flotation flow process.Partial reflux (reflux ratio 50%) pressurized dissolved air flotation technology is the air supporting method that the most often adopts both at home and abroad at present.But also there is deficiency in the traditional dissolved air flotation device that utilizes partial reflux pressurized dissolved air flotation principle to produce: the air-floating apparatus building block is many, system complex, bubble diameter are big, install fluctuation of service, water outlet entrained bubbles.
The utility model content
The utility model provides a kind of simple in structure, clean effect good, detersive efficiency is high full-automatic dissolved air flotation device in order to overcome the above problems.
The technical scheme of the utility model is: comprise air supporting casing, regulating weir, water-in, water outlet, sewage draining exit, dissolving, mud scraper and dreg collecting slot; Described mud scraper is arranged on air supporting casing top; Described dissolved air flotation device also comprises air dissolved pump and receives the water dewatering system; Described air dissolved pump is arranged on the air supporting lower box outside, and air dissolved pump one end connects dissolving, and the other end connects return line and is communicated in the air supporting casing; Described receipts water degasification system is arranged on the air supporting lower box and connects regulating weir.
The utility model improves on the basis of traditional air-dissolving air-float; Air-floating apparatus adopts air dissolved pump to replace traditional force (forcing) pump, air compressor machine, ejector, high pressure dissolving, gas-water mixer and discharges first-class; Overcome the problem that conventional apparatus system complex, fluctuation of service and air pocket seethe, the device interior science is provided with reflux line, sets up the inner water degasification system of receiving; Avoid the water outlet entrained bubbles, influence subsequent disposal.
