Description
Technical field
The utility model relates to a kind of air-flotation type waste disposal plant.
Background technology
Method of wastewater treatment can be divided into two big classes: biochemical process and physico-chemical processes.Physico-chemical processes mainly is to adopt coagulation-settlement process or coagulate gas floating process to handle waste water.Coagulation-settlement process is the traditional technology that widely adopt in the waste water treatment field, its characteristics are that the Technology difficulty is little, and are easy and simple to handle, but occupation of land is big, precipitation is not thorough, treatment effect is unstable, especially when waste strength was higher, the sludge quantity of generation can reach 10～30% of wastewater flow rate.Coagulate gas floating process then is that coagulation-settlement process is combined with air-float technology: sewage carries out coagulating earlier, then adopt air-float technology to make the suspended substance in the sewage form scum silica frost at adhesive attraction float downward to the water surface of a large amount of intensive microbubbles, utilize again and scrape slag equipment scum silica frost is removed, reach the purpose that purifies water.Adopt coagulate gas floating process to handle trade effluent and sanitary wastewater, the clearance height of suspended substance in the waste water, good sewage processing effect.
Present coagulation air-float device is made up of coagulation reaction tank and air-floating apparatus, and air-floating apparatus is made up of air flotation pool, reliever, molten gas equipment.Wherein coagulation reaction tank can be built very greatly, but air flotation pool can not be too big.The reason that the restriction air flotation pool maximizes mainly is the equilibrium that is difficult to realize hydraulics in Da Chi, and pool inner water flow velocity degree is unbalanced, not only can destroy the suspension flco behind the coagulation, also can cause the short circuit of air flotation zone, influences air flotation effect.Therefore the waste water air-float technology of the especially difficult flocculation of the Industrial Wastewater Treatment form that adopts coagulation reaction tank and air flotation pool branch to build, and device miniaturization more, a present cover air-floating apparatus maximum day the amount of disposing of sewage can only 3000 tons.Want to improve sewage treatment capacity, can only increase the tricks of air-floating apparatus, certainly will cause problems such as occupation of land, investment are big, operation inconvenience like this.
Pressure air-dissolving mode in the air-float technology mainly contains: 1) air compressor machine pressure air-dissolving form: molten gas equipment is made up of dissolving, air compressor machine, pressure pump.Water fully enters dissolving after the water pump pressurization, and by air compressor machine air is introduced in the dissolving.Help improving the solubleness of air in water though improve the pressure of air dissolving system, but in the pressure air-dissolving system, the dispersity of gas, liquid two-phase and flow velocity are subjected to the restriction of system condition, solubleness can not reach capacity, general molten gas efficient only is 60～70%, has directly influenced the air supporting treatment effect; 2) intubate molten gas form in full before the pump: molten gas equipment by pump before intubate, dissolving, pressure pump form, air by pump before intubate introduce in the pressure pump, under the effect of water pump impeller, mix, cut with water, realize gas miscible in water, then enter dissolving, will mix gas release soluble in water by the perforation dissolved air water rising pipe in the air flotation pool again and come out.Because mixing, the cutting of the miscible main dependence water pump impeller of air, the air capacity of dissolving in also will be restricted, and molten gas efficient has only 30～50%, and dissolved air water quality instability, and the air supporting treatment effect is undesirable.
The utility model content
