Description
Technical field
The present invention relates to a kind of air-floating apparatus, particularly a kind of organism gas float treatment unit.
Background technology
Flotation waste water treatment is meant manages in water, to feed or produce a large amount of micro bubbles, and it is adhered on the impurity wadding grain, causes the state of density less than water, and relies on buoyancy that it is floated to the water surface, thereby realize solid-liquid separation.Because the density of air is much littler than water, has only 1/775 of water, therefore adhered to the wadding grain of some amount microbubble, its ascent rate is much faster than the sinking velocity of former wadding grain, thereby causes the disengaging time much shorter of air supporting method than the precipitator method.In addition, the air supporting method not only go turbid, be superior to settling tank aspect discoloring, and the COD in reducing polluted source, xylogen and improve and unique advantage is all arranged aspect the oxygen in water.Lower than settling tank cost, the residence time is short, and floor space is little.
The biological filter be under aerobic condition, utilize attached to the microbial film on the carrier to water in a kind of method of removing of biodegradable material.There are ordinary biofilter (trickling filter), high-rate filter, tower biological filter, BAF etc. in biological filter commonly used at present.Its principle is: in the biological filter, sewage is evenly distributed in the surface, filter tank through water distributor, under action of gravity; Spray to drip shape, a part is adsorbed on filter material surface, becomes the water layer that adheres to that is film like; Another part is then with the form seepage flow filtering layer of film; Become mobile water layer, arrive water exhaust system at last, flow out outside the pond.During the effluent stream filter bed; Filtrate has been held back the suspended substance in the sewage; While is adsorbed on colloid in the sewage and dissolved matter on the surface of oneself; Organism is wherein utilized with growth and breeding by mikrobe, and these mikrobes have further been adsorbed the material that is suspension, colloid and dissolved state in the sewage again, have formed microbial film gradually.After the microbial film maturation; Perch on microbial film mikrobe promptly with the organism in the sewage as nutrition; Organism in the sewage is carried out the adsorption and oxidation effect; Pollutent in the water inlet contacts materialization and the biochemical action that produces with the filter tank filtrate simultaneously, and ammonia nitrogen, nitrite in the water are effectively removed, and sewage is purified.In the operational process of biological filter, hydraulic load, organic loading and oxygen supply condition are the important factors that influences the biological filter performance.In conjunction with above-mentioned analysis; The biological filter is an aerobic treatment process, if can make full use of the dissolved oxygen in leading portion treatment process (air supporting) water outlet, then can reduce aeration rate; Cut down the consumption of energy, so it can be regarded as a kind of efficient low-consume purification of water quality treatment process with Sustainable development meaning.
Summary of the invention
The objective of the invention is to organically physico-chemical process and biochemical method combined; Flat flow organism gas float treatment unit is provided; It effectively utilizes the solid-liquid separation function of traditional air flotation pool, and the space uses fully under the zone of action liquid that again can be creatively that traditional air supporting is vacant, introduces microbial film; Handle through biological chemistry, reach the purpose of removing BOD in the sewage.
For achieving the above object, the present invention adopts following technical scheme to realize:
The organism gas float treatment unit; Comprise air flotation pool, air dissolving system and material collection system, laterally be provided with reaction zone of action, disengaging zone and the Rinsing Area that is interconnected successively in the said air flotation pool, said air dissolving system comprises air dissolved pump, dissolving and dissolved air release; Said material collection system comprises scraping device and receiving tank; Below, said reaction zone of action is provided with dissolved air release, it is characterized in that bottom, said disengaging zone sets gradually biochemical zone of action and aeration aerating district.The densification that the aeration aerating district forms and trickle small bubbles provide sufficient and oxygen efficiently for biochemical zone of action.When this zone of flowing through downwards through the sewage of solid-liquid separation, the BOD in the sewage is effectively degraded at this.
Further, arrange the biofilm packing layer in the said biochemical zone of action, through COD in the biochemical method degradation water.
Further, the below of said biofilm packing layer is provided with dissolved air release, reaches high efficient aeration and prevents that biofilm detachment from influencing the purpose of system's effluent quality with this.
Further, in the said aeration aerating district micro bubble generation device is set.
Further, said scraping device comprise motor, by said motor-driven sprocket wheel and the traction scraper plate that drives by said sprocket wheel.
Further, bottom, said disengaging zone is provided with the perforation header that communicates with said Rinsing Area.
Further, be connected with liquid level on the said Rinsing Area and regulate weir plate.
The invention has the beneficial effects as follows:, reach the reduction COD of sewage effectively through the combination of physical chemistry and biochemical method; Adopt the dissolved air release aeration, greatly improved aeration efficient, energy efficient.
